History of C language

By
The C language was developed at AT & T (American Telegraph & Telephone)  Bell Laboratories in the early 1972's by a system programmer named Dennis Ritchie. It was written originally for programming under an operating system called UNIX which itself was later rewritten almost entirely in C. Its name encrypted as C, derives from the fact that it is based on an earlier version written by Ken Thompson, another Bell laboratories system engineer. He adapted it from a language that was known by the initials BCPL (Basic Combined Programming Language). Thompson derived his programming language name as B, the first of the initials BCPL. When the language was modified and improved to its present state, the second letter of BCPL, C was given to it. The C language is often described as a middle level language. It permits programs to be written in much the same style as that of most of high-level programming language. It also interacts with the inner workings of the computer. The American National Standards Institute (ANSI) has established certain standards for C which is known as ANSI C in addition to the original version of C developed by Dennis Ritchie. The another popular version of C is Turbo C.

What is Java Applets?

By
An applet is a special kind of Java program that is designed to be transmitted over the Internet and automatically executed by a Java-compatible web browser. Furthermore, an applet is downloaded on demand, without further interaction with the user. If the user clicks a link that contains an applet, the applet will be automatically downloaded and run in the browser. Applets are intended to be small programs. They are typically used to display data provided by the server, handle user input, or provide simple functions, such as a loan calculator, that execute locally, rather than on the server. In essence, the applet allows some functionality to be moved from the server to the client.
