Hi! I'm Java...

Java is a computer programming language. It enables programmers to write computer instructions using English based commands, instead of having to write in numeric codes. It’s known as a “high-level” language because it can be read and written easily by humans. Like English, Java has a set of rules that determine how the instructions are written. These rules are known as its “syntax”. Once a program has been written, the high-level instructions are translated into numeric codes that computers can understand and execute. Who Created Java? In the early nineties, Java was created by a team led by James Gosling for Sun Microsystems. It was originally designed for use on digital mobile devices, such as cell phones. However, when Java 1.0 was released to the public in 1996, its main focus had shifted to use on the Internet. It provided more interactivity with users by giving developers a way to produce animated webpages . Over the years it has evolved as a successful language for

I'm the Server Operating System

Server Operating System A server operating system is software that was especially developed to serve as a platform for running multi-user computer programs, applications that are networked and programs critical to business computing. This type of operating system (OS) often comes bundled with the most common types of applications deployed in the client-server model, a term used to indicate the exchange of information between computers. For example, a hypertext transfer protocol (HTTP) or web server hosts or "holds" the text files, images files and scripts that work together to form a website. When someone connects to the Internet and types in a web address, the server that holds the files of the site delivers or "serves" the requested pages to the client computer or the machine that made the request. Frequently used applications in the client-server model handle operations for sharing files and printers across a network, hosting and serving web pages via the
