Computer programmers write, test and implement code necessary to make certain functions happen on a computer. In this section, learn about programs like Perl and Java or how relational databases and algorithms work.
Although numerous computer languages are used for writing computer applications, the computer programming language, C, is the most popular language worldwide. Learn more about the benefits of learning C programming from this article.
When you use programming to tell a computer what to do, you also get to choose how it's going to do it. That's where computer algorithms come in. The algorithm is the basic technique used to get the job done.
The relational database was born in 1970 when E.F. Codd, a researcher at IBM, wrote a paper outlining the process. At the time, databases were "flat," and stored as one long text file. Learn how the relational database changed the way we work.
CGI, or common gateway interface, allows Web servers to store dynamic Web pages that can change and update rather than remain a fixed page. This article explains the process, plus shows you how to write your own scripts.
Perl is easy to use once you know the basics. It can be used to create DOS batch files, C shell scripts, CGI scripts for Web pages and more. Get a great introduction to this versatile programming language.
