PERL is a computer programming language similar to C developed for running on Unix and Unix like systems. Though PERL is mainly used in Linux environment in the web servers its also gaining popularity for usage in Windows and Mac OSX and other OS platforms. PERL is platform independent. PERL was developed by its founder Larry Hall in the 1980s who was working with NASA at that time in the data processing department. He developed this code to make processing of NASA data faster and to produce reports from huge collection of data .
Courtesy this for the term PERL a Back Acronym has been formed called Practical Extraction and Report Language.
PERL is considered to be on of the best choices for developing Common Gateway Interface programmes courtesy its superior ability to handle Text and Images. PERL is considered to be as fast as C language but with less amount of coding and as a result of that PERL is considered an easier computer language to learn code than that with C and C++.
Applications and Usage:
PERL has two main versions available today they being PERL 5 and PERL 6. They are completely different software but have the same predecessor that is PERL. PERL 5 is extensively used for creation of Graphics Software alongside being used as a popular Common Gateway Interface programme for Apache Web Servers.
Apache Web Servers with the help of the mod_Perl can run PERL CHI scripts and that makes it an immensely popular choice for developing CHO scripts and web software with PERL language.
Courtesy its versatile usage which spans an wide array of IT services its known as “the Swiss Army chainsaw of scripting languages”. But courtesy is complex and considered jagged code it at times it also has been Back Acronymed as “Pathologically Eclectic Rubbish Lister” which is stated to be a term given by the founder Larry Hall himself.
In-spite of its rigged coding its immensely popular with web software developers and in the web hosting industry. It also ha a decent number of followers from other spheres of the IT industry like Software Developers, Programmers, System Administrators, Network Administrators.
Software Architecture and System Requirements:
Perl is a Free Open Source Software which is available under Artistic License and the GNU General Public License. Back in the 1980s it was developed by Larry Hall while he was working at NASA for Unix Computers. Present day PERL is platform independent but is mostly used in Unix and Unix like Systems like Linux. Its popularity in the Windows platform and Windows Web Servers have grown over the last few decades. It is stated that any software or code that has been developed properly with PERL will transfer from one Operating System to another without any problem.
PERL is considered to be one of the most versatile and popular Computer Languages developed in the world till date. Derived from the language C its similar in syntax architecture to that of the C Language but is less complex and much easier to learn than the C language.

What is CGI?
CGI is the acronym for Common Gateway Interface which is a process by which the Web Servers talk and exchange information with various web software that runs on the web servers. Though CGI scripts can be be written by any programming language, courtesy a plugin of Apache known as mod_Perl most web servers use PERL in the operational back end.
What is Apache
Apache is a modern day http web server that most web hosting companies use today. It makes possible of running various CGI programs written in PERL to run via a module called mod_Perl.
What is Active PERL?
It is a distribution of PERL developed by the company ActiveState. The free version aimed at the open source community is very popular among web developers and software developers. ActiveState also has some paid versions of the software targeted at Business houses and big Enterprises.
Is PERL better than C language?
PERL is less comprehensive and less structured language than C or C++ and in effect it tries to be a simpler kind of programming language compared to the other two. C though can run faster that PERL at times but complex PERL programmes can run faster than complex C programmes on a fast computer. In short PERL is a simpler language that C or C++ and lighter and less complex coding. And unlike C or C++ PERL developers believe that there are many ways to do a task and not just only one.
Perl the holy grain of CGI on the Internet, who doesn’t want to learn it! Its a language how much you might want to hate it for its complex coding its something you cant do without on the net today. When it became quite apparent that I will be working in the CGI industry PERL was surely my chosen language to pick up. By that time I was working as a web software developer and depended on C++ so once I came across this course I did not hesitate to pick it up. Now a days starting from Apache to eCommerce Gateways and normal web interfaces everything runs on PERL. Kudos to that man Larry Wall for this PERL. The tutorial presented here is comprehensive and I have gained a lot of insight on the language. So what ever my fears were regarding learning a new programming language has got totally trashed while learning the course. It’s a good one. Take it up!
Being a Web Programmer it was natural for me to chose to learn PERL as a coding language as so many site software are based and developed in PERL. So not learning it was not an option. Once I took up the course it has been a decent experience in learning it as the instructor has given a nice over view of the language. I liked learning the course here in this site. Thanks to EduCBA.
Being an Web Development student I am learning this as a side hobby language kind of. I know how important it is to learn and use in the modern day world where everything in the Internet almost gets coded by PERL. Its complex and now a days many want to work on Python which is a simpler script but I personally like the methodology of PERL. I am personally a fan of PERL 5. The language though looks over powering at times thanks to the tutor in this site I did not have any problems in picking it up.
I always wanted to learn PERL. I am in the software development industry and I though am a C++ programmer I find PERL easy to use and less comprehensive than C++. Its a good language to learn. I also got my eyes on Python which philosophically is very different from PERL. But learning PERL is like learning the secret code of the world wide web as everything now a days are coded in PERL for the Internet industry.
So shying away from PERL is not a good idea. So I decide to take up this course. PERL has drawn inspirations from C and C++ also so learning it was easy for me. I should add here that the trainer has explained the concepts of PERL in a very easy and comfortable way for everyone to pick it up for. So it was a good decision to take up this course and learn it. It has been a good experience so far.
Career Benefits of this training
PERL happens to be the most commonly used web programming language out there in the world today.
