What Is Perl?

Perl is a language of the practical extraction and reporting. This language was created by Larry Wall in 1987. That time he was working on the bug-tracking system and the AWK programming language.

Perl is a high level programming language of interpretation. The programming languages can be referred to different levels:

  • high level - only people can understand such type of languages;
  • interpretation level - can translate the languages from the high level into the low one, and vice versa;
  • low level - the languages can be understood only by machines.

For example, machines are able to perceive only a binary code (low-level language) which is rather hard to understand for people. Perl consists of the simple English words, it is easily perceived by people, hence, it refers to the high-level languages.

But the computers do not understand such language. In order to solve this problem, there is an interpreting level among the program languages.

Where Can Perl Be Utilized?

  • Web development, namely programming with the CGI (Common Gateway interface) usage.
  • Automation of the tasks for web server and other administrative tasks. With Perl, one can automate mail and system cleaning up.
  • Networking.
  • Bioinformatics.

Perl is used for generating reports and extracting information. It can create reports via using resources and discover security errors in the network.

Talking about CGI programming, the programs of such type assist web server to dynamically interact with users.

Executing functional testing, UI checking, usability testing, performance control, unit testing, configuration checking, web application system testing, the specialists may face Perl.
