INHERITANCE
Inheritance is actually what?
Inheritance is a big advantage in object-based programming because of a property or method defined in the superclass, this property is automatically inherited from all subclasses.Superclass is a parent class that can be bequeathed to the subclass. And what about super classs or superclass defines this?
The way you just simply use the keyword "extends"
Well this is an example of a super class:

public class DokterUmum{
public String kodeDokter,namaDokter;
public double biayaObat,biayaPeriksa;
public DokterUmum(){
this.kodeDokter="e4500";
this.namaDokter="Ulil";
this.biayaObat=45000.0;
this.biayaPeriksa=40000.0;
}
public void setNamaDokter(String namaDokter){
this.namaDokter=namaDokter;
}
public void setKodeDokter(String kodeDokter){
this.kodeDokter=kodeDokter;
}
public void setBiayaObat(double biayaObat){
this.biayaObat=biayaObat;
}
public void setBiayaPeriksa(double biayaPeriksa){
this. biayaPeriksa= biayaPeriksa;
}
public String getKodeDokter(){
return kodeDokter;
}
public String getNamaDokter(){
return namaDokter;
}
public double getBiayaObat(){
return biayaObat;
}
public double getBiayaPeriksa(){
return biayaPeriksa;
}
public double TotalBiaya(){
return(biayaObat+biayaPeriksa);
}
}

Setelah decompile maka hasilnya seperti ini :

Do not worry about these results do not mean the program you are wrong .... ok
Because that was the response from java to the super class.
Well this is an example of a subclass program:

class DokterJantung extends DokterUmum
{
public double biayaSpesialis;
public String titleBelakang;
public DokterJantung(){
this.biayaSpesialis=50000.0;
this.titleBelakang="Maria SP.J";
}
public void setBiayaSpesialis(double biayaSpesialis)
{
this.biayaSpesialis=biayaSpesialis;
}
public void setTitleBelakang(String TitleBelakang)
{
this.titleBelakang=TitleBelakang;
}

public double getBiayaSpesialis(){
return biayaSpesialis;
}

public String getTitleBelakang(){
return titleBelakang;
}
public double TotalBiaya(){

return (biayaObat+biayaPeriksa+biayaSpesialis);
}
public static void main (String[]args){
DokterJantung dj = new DokterJantung();
dj.setBiayaSpesialis(70000.0);
dj.setTitleBelakang("Sarwinto SP.J");
System.out.println("Biaya Spesialis =" +dj.getBiayaSpesialis());

System.out.println("Nama Dokter =" +dj.getTitleBelakang());
double TotalBiaya=dj.TotalBiaya();
System.out.println("Total Biaya =" +TotalBiaya);
}
}

These are the results compiled from the subclass is above the super classnya DokterUmum

Well this is an example of a subclass program:...

Insert Component

2009-06-14T22:00:00.000-07:00

Often it is necessary to add a component between components that are already placed in a form. Whenever you add a component between two existing components, the GUI Builder automatically shifts them to make room for the new component. To demonstrate this, we'll insert a JTextField component between the Title: and Nickname: components we added previously.

1. Insert a JTextField component between two JLabel components

* In the Palette window, select the JTextField component from the Swing Controls section.
* Move the cursor over the Title: and Nickname: JLabels on the second row such that the JTextField overlaps both and is aligned to their baselines.
* Observe that the Text Field component is inserted between the Title: and Nickname: Labels.
2. Add a Text Field component.

* Drag a new Text Field component and place it just beside Nickname: Label component.
* Extend the newly added Text Field component to the right edge of the Panel.
Good luck!!!

How to Creating Java Files

2009-05-24T23:15:00.000-07:00

NetBeans IDE contains templates and wizards that you can use to create all kinds of source files,

from Java source files to XML documents and resource bundles.
The easiest way to create a file is to right-click the directory
node in the Filesystem window where you want to create
the file and choose from the New submenu in the node's
contextual menu. The New submenu contains shortcuts to
commonly-used templates and an All Templates command
that you can use to choose from all NetBeans templates

To demonstrate some of the IDE's source creation and
editing features, let's recreate the ColorPreview class that
comes with the colorpicker example in the IDE's sample
code. Right-click any directory in your mounted filesystems and choose New > Java Class. Name the
file ColorPreview and click Finish. The file opens in the Source Editor.

Java Identifier,,,

2009-04-27T23:47:00.000-07:00

Identifiers are names we give to our variables, constants, classes, and methods.
Identifiers is token to word presntation.

Identifiers must comply with these rules:

* The first character of an identifier must be a letter, an underscore(_), or a dollar sign($).
* The rest of the characters in the identifier can be a letter, underscore, dollar sign, or digit. Note that spaces are NOT allowed in identifiers.
* Identifiers are case-sensitive. This means that age and Age are different identifiers.
* Identifiers cannot match any of Java's reserved words.

Although not required, we strongly recommend that you name your identifiers using Java naming conventions.

Examples:
These identifiers are valid:

MyClass
$amount
$change
username
user_name
_sys_var1
totalGrades;
TotalGrades;
one
zero

And These identifiers are NOT valid:

My Class // spaces are not allowed
numberOf*s // the asterisk cannot be used
final // final is a reserved word
1Way // identifiers cannot start with a digit

Token_Ring,,,

2009-04-13T00:49:00.000-07:00

Token ring local area network (LAN) technology is a local area network protocol which resides at the data link layer (DLL) of the OSI model. It uses a special three-byte frame called a token that travels around the ring.

Unlike Ethernet, Token Ring uses a ring topology whereby the data is sent from one machine to the next and so on around the ring until it ends up back where it started. It also uses a token passing protocol which means that a machine can only use the network when it has control of the Token, this ensures that there are no collisions because only one machine can use the network at any given time.
*The Basics
Here is an animated GIF that shows the basic operation of a Token Ring, and below is an explanation of what is going on.
Although 16Mbps is the standard ring speed these days (and Fast Token Ring is being developed) we will consider a 4Mbps Token Ring in this tutorial to explain the basic concepts.

Post Office Protocol 3???

2009-04-13T00:27:00.000-07:00

POP3 (Post Office Protocol 3) is the most recent version of a standard protocol for receiving e-mail. POP3 is a client/server protocol in which e-mail is received and held for you by your Internet server.
Periodically, you (or your client e-mail receiver) check your mail-box on the server and download any mail, probably using POP3.
This standard protocol is built into most popular e-mail products, such as Eudora and Outlook Express.
It's also built into the Netscape and Microsoft Internet Explorer browsers.

POP3 is designed to delete mail on the server as soon as the user has downloaded it. However, some implementations allow users or an administrator to specify that mail be saved for some period of time. POP can be thought of as a "store-and-forward" service.

An alternative protocol is Internet Message Access Protocol (IMAP). IMAP provides the user more capabilities for retaining e-mail on the server and for organizing it in folders on the server. IMAP can be thought of as a remote file server.

POP and IMAP deal with the receiving of e-mail and are not to be confused with the Simple Mail Transfer Protocol (SMTP), a protocol for transferring e-mail across the Internet.
You send e-mail with SMTP and a mail handler receives it on your recipient's behalf. Then the mail is read using POP or IMAP.

Reasons to Use a Java Scripting Language

2009-04-02T02:01:00.000-07:00

Most scripting languages are dynamically typed. You can usually create new variables without predetermining the variable type, and you can reuse variables to store values of different types. Also, scripting languages tend to perform many type conversions automatically, for example, converting the number 10 to the text "10" as necessary. Although some scripting languages are compiled, most languages are interpreted. Script environments generally perform the script compilation and execution within the same process. Usually, these environments also parse and compile scripts into intermediate code when they are first executed.

These qualities of scripting languages help you write applications faster, execute commands repeatedly, and tie together components from different technologies. Special-purpose scripting languages can perform specific tasks more easily or more quickly than can more general-purpose languages. For example, many developers think that the Perl scripting language is a great way to process text and to generate reports. Other developers use the scripting languages available in bash or ksh command shells for both command and job control. Other scripting languages help to define user interfaces or web content conveniently. Developers might use the Java programming language and platform for any of these tasks, but scripting languages sometimes perform the job as well or better. This fact doesn't detract from the power and richness of the Java platform but simply acknowledges that scripting languages have an important place in the developer's toolbox.

Combining scripting languages with the Java platform provides developers an opportunity to leverage the abilities of both environments. You can continue to use scripting languages for all the reasons you already have, and you can use the powerful Java class library to extend the abilities of those languages. If you are a Java language programmer, you now have the ability to ship applications that your customers can significantly and dynamically customize. The synergy between the Java platform and scripting languages produces an environment in which developers and end users can collaborate to create more useful, dynamic applications.

For example, imagine a calculator with a set of core operations. Although the base calculator may have only four or five fundamental operations, you can provide programmable function keys that the user can customize. Customers can use whatever scripting language they prefer to add mortgage calculations, temperature conversions, or even more complex functionality to the calculator. Another example of this collaboration could be a word processor that allows customers to provide customized filters for generating various file formats. Examples throughout the remainder of this article will show how to use scripting to provide customizable Java applications for your customers.

File Sync Service

2009-02-28T03:54:00.000-08:00

Access your files from anywhere!

What's File Sync, or file synchronization? You may also have heard it called File Mirroring, or File Replication. Simply, file sync automatically copies files from one computer to another. Let's describe the problem...

Have you ever left important documents on a laptop, and left it at home or worse, had it stolen? Have you had your hard drive crash, and lost weeks or months of work? What about when the technicians at work imaged your machine, and lost all of your files on your workstation's hard drive? There are many people that have been in a situation like this... ourselves included. We use our own file sync system to keep our files safe. If our hard drive crashes... no problem. Install the client on a new computer, and the files automatically download to the new machine. Forgot the laptop? No problem again. Connect to the web site using the web browser on any machine, and download whatever files are needed. Simple yet powerful.

As well as disaster recovery, use file synchronization for keeping the versions of the files the same on all your machines. When working on a file on one machine, then a different one, it's annoying to have to copy your files back and forth, making sure you are always working on the most recent copy. With file sync, you don't have to carry a floppy, CD, USB stick or whatever to constantly update the file on multiple computers. The file sync system does all the work for you!

There's another benefit of file sync that many of our customers use. If your company or group needs to share files for collaboration work or teleworking, but don't have a server to share them, you can sign up for a shared file sync account. All the files that you choose will be synchronized among all your machines quickly and easily. The files you use will always be available, securely transmitted and stored.

Don't worry about files "out there" on the Internet, either. The Little Networks File Sync uses Blowfish as it's encryption system on the server. Using 128-bit strong encryption, it is very secure. Not even the administrators of the system know what files are stored there. All communications to sync files use SSL, a well-known and secure means of encrypting your communication streams.

You can think of file sync in a couple ways.. as a means of keeping your files up-to-date on all your machines, and as insurance for your data. Did you know 60% of companies that lose their data close down within 6 months? And 72% of business that suffer major data loss disappear within 2 years? Did you know that thousands of PC's from businesses are stolen every year, particularly laptops? Think about what would happen if all your critical business data was lost, and then think about how much it is worth to you. No matter how much it is, it's worth it to be able to recover from a data loss. Look at our Get File Sync! page to find out how easy it is to ensure that your valuable data is available anytime, anywhere.

A free 50 MB account is available, at no cost or obligation to you. Try our time-tested file synchronization solution now!!!!Ok!

How LCDs Work?

2009-02-28T01:13:00.000-08:00

You probably use items containing an LCD (liquid crystal display) every day. They are all around us -- in laptop computers, digital clocks and watches, microwave ovens, CD players and many other electronic devices. LCDs are common because they offer some real advantages over other display technologies. They are thinner and lighter and draw much less power than cathode ray tubes (CRTs), for example.

But just what are these things called liquid crystals? The name "liquid crystal" sounds like a contradiction. We think of a crystal as a solid material like quartz, usually as hard as rock, and a liquid is obviously different. How could any material combine the two?
We learned in school that there are three common states of matter: solid, liquid or gaseous. Solids act the way they do because their molecules always maintain their orientation and stay in the same position with respect to one another. The molecules in liquids are just the opposite: They can change their orientation and move anywhere in the liquid. But there are some substances that can exist in an odd state that is sort of like a liquid and sort of like a solid. When they are in this state, their molecules tend to maintain their orientation, like the molecules in a solid, but also move around to different positions, like the molecules in a liquid. This means that liquid crystals are neither a solid nor a liquid. That's how they ended up with their seemingly contradictory name.

So, do liquid crystals act like solids or liquids or something else? It turns out that liquid crystals are closer to a liquid state than a solid. It takes a fair amount of heat to change a suitable substance from a solid into a liquid crystal, and it only takes a little more heat to turn that same liquid crystal into a real liquid. This explains why liquid crystals are very sensitive to temperature and why they are used to make thermometers and mood rings. It also explains why a laptop computer display may act funny in cold weather or during a hot day at the beach.

BOOT ORDER,,,

2009-02-23T01:53:00.001-08:00

This is the most important setting for when you first build your computer. The boot order determines which devices the motherboard will look at for an operating system or installer. The options typically include Hard Drive, Optical Drive, Floppy Drive, Network and Other. The standard order at first startup is Floppy, Hard Drive, Optical Drive and Other. This will generally cause the system to find the hard drive first which will not have a functional operating system on the computer.

The proper sequence for the installation of a new operating system should be Floppy, Optical Drive, Hard Drive and Other. This allows the computer to but from the OS installation CD that has a bootable installer program on it. Once the hard drive has been formatted and the OS installed, it is important to then restore the boot order of the computer to the original of Floppy, Hard Drive, Optical Drive and Other.

Wireless Networking Equipment

2009-02-14T04:58:00.000-08:00

What sort of hardware is required to build a wireless network is dependent on the type of network you intend to build.
If you have two devices with wireless network adapters- whether wireless enabled PDA's, laptops or desktop computers- you can technically connect them in an ad hoc wireless network. Essentially, any devices enabled with wireless network adapters within range of each other can all communicate with each other over such an ad hoc network.

If you want to build a more traditional network- where multiple clients connect to a central point which acts as a gateway to the rest of the world- you will also need a wireless router or wireless access point to implement an infrastructure mode network.

A wireless router has a physical network connection which would be connected to a wired network. It could be connected to a hub or switch on a network or for home users would generally be connected to your cable or DSL modem. All of the wireless-enabled clients would then connect to the wireless router. Typically the wireless router will act as the DNS server and Internet gateway for the clients attached to it and it can also be configured to provide IP addresses automatically using DHCP.

A wireless access point (AP) can be used to join wireless devices to a wired network, or to extend the range of a wireless network. They don't provide the DNS, DHCP, firewall or other functions commonly found in wireless routers. They simply take a wired or wireless network input and relay it to the wireless devices within its broadcast range.

*To summarize, the primary components of a wireless network include:

1. Wireless Network Adapter: this is often a slim, credit-card sized pcmcia device. There are wireless network adapter PCI cards for desktop computer systems as well as adapter cards that allow desktop computers to use the PCMCIA cards. Another option for wireless network adapters is USB which simply plug into an available USB port to provide wireless connectivity.
2. Wireless Router:Acts similar to a wired router to connect networked devices to other networks or to the Internet. Common features of a wireless router include DNS, DHCP, firewall and encryption.
3. Wireless Access Point:A wireless access point is more like a hub for wireless networks. It does not implement a different IP address range or provide the other features of a wireless router. It simply relays network traffic to the wireless devices within its broadcast range.
4. Wireless Antenna:In some cases a wireless antenna may be required to either extend the broadcast range of a router or access point or to increase the range from which a wireless network adapter can receive a signal.

GUI Definition

2009-02-09T22:25:00.000-08:00

A graphical user interface (GUI) is a human-computer interface (i.e., a way for humans to interact with computers) that uses windows, icons and menus and which can be manipulated by a mouse (and often to a limited extent by a keyboard as well).

GUIs stand in sharp contrast to command line interfaces (CLIs), which use only text and are accessed solely by a keyboard. The most familiar example of a CLI to many people is MS-DOS. Another example is Linux when it is used in console mode (i.e., the entire screen shows text only).

A window is a (usually) rectangular portion of the monitor screen that can display its contents (e.g., a program, icons, a text file or an image) seemingly independently of the rest of the display screen. A major feature is the ability for multiple windows to be open simultaneously. Each window can display a different application, or each can display different files (e.g., text, image or spreadsheet files) that have been opened or created with a single application.

An icon is a small picture or symbol in a GUI that represents a program (or command), a file, a directory or a device (such as a hard disk or floppy). Icons are used both on the desktop and within application programs. Examples include small rectangles (to represent files), file folders (to represent directories), a trash can (to indicate a place to dispose of unwanted files and directories) and buttons on web browsers (for navigating to previous pages, for reloading the current page, etc.).

Commands are issued in the GUI by using a mouse, trackball or touchpad to first move a pointer on the screen to, or on top of, the icon, menu item or window of interest in order to select that object. Then, for example, icons and windows can be moved by dragging (moving the mouse with the held down) and objects or programs can be opened by clicking on their icons.

Advantages of GUIs

A major advantage of GUIs is that they make computer operation more intuitive, and thus easier to learn and use. For example, it is much easier for a new user to move a file from one directory to another by dragging its icon with the mouse than by having to remember and type seemingly arcane commands to accomplish the same task.

Adding to this intuitiveness of operation is the fact that GUIs generally provide users with immediate, visual feedback about the effect of each action. For example, when a user deletes an icon representing a file, the icon immediately disappears, confirming that the file has been deleted (or at least sent to the trash can). This contrasts with the situation for a CLI, in which the user types a delete command (inclusive of the name of the file to be deleted) but receives no automatic feedback indicating that the file has actually been removed.

In addition, GUIs allow users to take full advantage of the powerful multitasking (the ability for multiple programs and/or multiple instances of single programs to run simultaneously) capabilities of modern operating systems by allowing such multiple programs and/or instances to be displayed simultaneously. The result is a large increase in the flexibility of computer use and a consequent rise in user productivity.

But the GUI has became much more than a mere convenience. It has also become the standard in human-computer interaction, and it has influenced the work of a generation of computer users. Moreover, it has led to the development of new types of applications and entire new industries. An example is desktop publishing, which has revolutionized (and partly wiped out) the traditional printing and typesetting industry.

Despite the great convenience of the GUI however, system administrators and other advanced users tend to prefer the CLI for many operations because it is frequently more convenient and generally more powerful1. On Unix-like operating systems, GUIs are actually just attractive, convenient coverings for command line programs (i.e., programs which operate from a CLI), and they rely on them for their operation.

One of the great attractions of Unix-like operating systems is that they have maintained their CLI capabilities while continuing to improve their GUIs, thereby allowing advanced users to harness the full power of the computer while simultaneously making it easier for beginning and intermediate users. In contrast, the newer versions of Microsoft Windows (such as 2000 and XP) have downgraded their CLIs to marginal roles.

Brief History

The origin of the GUI can be traced back to Vannevar Bush, a scientist and futurist who worked at the Massachusetts Institute of Technology (MIT) during World War II. In his now classic 1945 magazine article As We May Think, Bush proposed an information administration tool, the Memex, that would allow data to be stored on microfilm and made easily accessible, linkable with hyperlinks and programmable.

In 1963 Ivan Sutherland, a graduate student at MIT, developed a program for his Ph.D. dissertation called Sketchpad, which allowed the direct manipulation of graphic objects on a CRT screen using a light pen. His concept included the capability to zoom in and out on the display, the provision of memory for storing objects and the ability to draw precision lines and corners on the screen.

Douglas Engelbart, who had already been researching in human-computer interaction at Stanford University in the early 1950s, was greatly inspired by Bush's concepts. He unveiled the first primitive mouse in 1968 at the Fall Joint Computer Conference in San Francisco. Termed the X-Y Position Indicator, it was housed in a small wooden box with wheels, and it took the cursor with it on the display screen when it was rolled around on a horizontal surface.

Much additional progress occurred at Xerox Palo Alto Research Center (PARC), which Xerox Corporation established in 1970 in Palo Alto, California for the purpose of creating "the architecture of information" and "humanizing computers." This included developing the first usable GUI, which was incorporated into PARC's Alto computer. The Alto, which debuted in 1974, was envisioned as a smaller, more portable replacement for the mainframes that dominated computing at that time. However, it and its successor, the Xerox Star, never achieved commercial success, presumably due to their very high prices.

Steve Jobs, the co-founder of Apple Computer, was heavily inspired by the innovations at nearby PARC, and he thus decided to incorporate a GUI into his company's computers. Apple considerably extended PARC's work, including developing overlapping windows, manipulable icons, a fixed menu bar, dropdown menus and a trash can.

The Apple Macintosh, launched in 1984, was the first commercially successful use of a GUI. It was so successful, in fact, that the GUI was subsequently adopted by most other developers of operating systems and application software, and it is now used on (or at least available for) virtually all types of computers. Moreover, GUIs are employed in a wide range of other products as well, ranging from industrial controls to toys.

Microsoft announced development of its first operating system that incorporated a GUI in November 1983, and the initial version, Windows 1.0, was released in November 1985. Windows 2.0, released in December 1987, represented a major improvement over the primitive Windows 1.0 with its addition of icons and overlapping windows, but it was not until 1995 with the launching of Windows 95 that Microsoft was able to offer a relatively high quality GUI.

The Future

GUI design has made tremendous progress subsequent to the introduction of the Macintosh and Windows 95, and it is continuing to advance. This is the result of several factors, including advances in computer hardware (e.g., faster processors, more memory and higher resolution display devices), improvements in software and ever-greater demands by users and application developers.

A particularly important new application for GUIs in recent years has been browsers. In fact, browsers have come to rival the desktop metaphor (i.e., images representing files, folders and a trash can) that has characterized most general purpose GUIs to date. Other concepts are also being developed which could provide alternatives to the desktop metaphor.

One of the most interesting areas of exploration is GUIs that provide the user with the illusion of navigating through a three-dimensional space. Another area of research is increasing user control over GUI objects, such as being able to rotate and freely change the size and transparency of icons. Also being studied is the increased use of natural languages to interact with computers as a supplement or complement to GUIs.

1For example, CLI programs often offer more options than do their GUI counterparts, thereby providing greater flexibility of use. Also, multiple CLI commands can be combined using pipes to perform tasks that would be much more cumbersome to perform with GUI programs. In addition, the command line version of a program can sometimes to be used to perform a task when its GUI counterpart malfunctions or is not available.

Multitasking

Main article: Computer multitasking
Main article: Process Management(computing)
Multitasking refers to the running of multiple independent computer programs on the same computer, giving the appearance that it is performing the tasks at the same time. Since most computers can do at most one or two things at one time, this is generally done via time sharing, which means that each program uses a share of the computer's time to execute.

An operating system kernel contains a piece of software called a scheduler which determines how much time each program will spend executing, and in which order execution control should be passed to programs. Control is passed to a process by the kernel, which allows the program access to the CPU and memory. At a later time control is returned to the kernel through some mechanism, so that another program may be allowed to use the CPU. This so-called passing of control between the kernel and applications is called a context switch.

An early model which governed the allocation of time to programs was called cooperative multitasking. In this model, when control is passed to a program by the kernel, it may execute for as long as it wants before explicitly returning control to the kernel. This means that a malicious or malfunctioning program may not only prevent any other programs from using the CPU, but it can hang the entire system if it enters an infinite loop.

The philosophy governing preemptive multitasking is that of ensuring that all programs are given regular time on the CPU. This implies that all programs must be limited in how much time they are allowed to spend on the CPU without being interrupted. To accomplish this, modern operating system kernels make use of a timed interrupt. A protected mode timer is set by the kernel which triggers a return to supervisor mode after the specified time has elapsed. (See above sections on Interrupts and Dual Mode Operation.)

On many single user operating systems cooperative multitasking is perfectly adequate, as home computers generally run a small number of well tested programs. Windows NT was the first version of Microsoft Windows which enforced preemptive multitasking, but it didn't reach the home user market until Windows XP, (since Windows NT was targeted at professionals.)

What is a database???????

2009-01-24T05:40:00.000-08:00

A database is a collection of information that is organized so that it can easily be accessed, managed, and updated. In one view, databases can be classified according to types of content: bibliographic, full-text, numeric, and images.

In computing, databases are sometimes classified according to their organizational approach. The most prevalent approach is the relational database, a tabular database in which data is defined so that it can be reorganized and accessed in a number of different ways. A distributed database is one that can be dispersed or replicated among different points in a network. An object-oriented programming database is one that is congruent with the data defined in object classes and subclasses.

Computer databases typically contain aggregations of data records or files, such as sales transactions, product catalogs and inventories, and customer profiles. Typically, a database manager provides users the capabilities of controlling read/write access, specifying report generation, and analyzing usage. Databases and database managers are prevalent in large mainframe systems, but are also present in smaller distributed workstation and mid-range systems such as the AS/400 and on personal computers. SQL (Structured Query Language) is a standard language for making interactive queries from and updating a database such as IBM's DB2, Microsoft's Access, and database products from Oracle, Sybase, and Computer Associates.

XML WEB SERVICES

2009-01-02T01:36:00.000-08:00

Dalam pengertian yang sederhana , XML Web Services dapat di definisikan sebagai aplikasi yang diakses oleh aplikasi yang lain. Mungkin orang berpendapat itu semacam web site, tetapi itu bukan demikian. Ada perbedaan - perbedaan yang membedakan dengan web site.
Sesuai dengan namanya, XML Web Service menyimpan datanya dalam format XML dan karenanya menjadi multi platform dalam hal accessibilitynya. Bagi anda yang telah mengenal pemrograman dengan VB6, Delphi, Java, atau bahasa lain maka anda telah mengenal adanya berbagai library yang didalamnya terdapat berbagai function, property, dan event untuk memudahkan pembuatan aplikasi. Web Service dapat disamakan dengan library tersebut tetapi tidak memerlukan registrasi khusus ke dalam sistem operasi yang menyimpannya. Web Service tersimpan di Web Server sehingga dapat diakses oleh berbagai bahasa pemrograman dengan lebih mudah baik dalam lingkungan LAN maupun Internet.
Sistem Web Service ini diharapkan meningkatkan kolaborasi antar pemrogram dan perusahaan, yang memungkinkan sebuah fungsi di dalam Web Service dapat dipinjam oleh aplikasi lain tanpa perlu mengetahui detil pemrograman yang terdapat di dalamnya.

MEMBUAT PARTISI HARDISK DENGAN FDISK

Mungkin tutorial ini hanya akan jadi kenangan para maniak komputer angkatan 80-90an. Walaupun sudah tidak populer lagi saat ini, kiranya akan masih dapat bermanfaat buat ilmu pengetahuan. Minimal kita akan tahu kalau partisi pake DOS lumayan asyik juga, dan kakek-kakek kita dulu juga pake ini :D.Yang perlu anda siapkan :1. Komputer, yang jelas jadul / zaman dulu pentium satu atau sederajat, kl Pentium 4 kasian komputernya.2. Disket Bootable ato CD bootable atau yg gitulah3. Mulai experimen dengan memasukkan disket tadi dan menekan tombol power pada PC
Langkah-langkah mempartisi:1. Menampilkan Semua Partisiini tidak harus dilakukan, ini hanya untuk mengeahui partisi apa saja yang ada dalam hard disk anda. Boleh langsung lompat ke nomor 2.2. Menghapus Semua Partisi sebelum kita membuat partisi baru, maka kita harus menghapus terlebih dahulu semua partisi yang ada. Penghapusan tidak bisa langsung dimulai dari nomor 1 (primary dos partition) jika yang lainnya berisi partisi, harus dimulai dari nomor 4 (non-dos partition).3. Membuat Partisi Barusetelah semua partisi dihapus, barulah dibuat partisi baru.4. Mengaktifkan Partisiselanjutnyamengaktifkan partisi yang telah kita buat. Setup akan secara otomatis memilih drive C (drive 1) untuk partisi aktif.
