The Linux operating system was first made by Linus Torvalds in the University of Helsinki of Finland. It was just a hobby for him then, but his interest to develop a system that was supposed to exceed the Minix (small UNIX system) standards gave birth to the Linux system. It was in 1991 when he first released the 0.02 version. By 1994, the 1.0 version of Linux Kernel was born. His efforts at improving the system continued, and now, the rest is history. The CompTIA recognizes the need for the Linux system in the IT industry so much so that it has included it in its certification exams.

The CompTIA (Computing Technology Industry Association) Linux certificate is awarded to those who have proven knowledge of the Linux operating systems. The basic requirement to get the certificate is to pass the certification exams. Those qualified to take the certification exams are Information Technology (IT) professionals who already have between six to twelve months of experience in the Linux system. The computer-based, multiple-choice exam is based around the following subject matter: installation methods, boot loader configuration, managing packages (Debian and RPM management systems), using bash shell, security considerations, navigating directories via command line, security considerations, network administration (including TCP/IP configuration), managing configuration files, and mounting file systems (NFS, SMB or ext3).

The focus of the exam is on Linux as a server and network operating system, although configuration and performance of the X Window system is included in it, meaning only a few questions are related to Linux as a desktop platform. The Linux exam is designed to be vendor-neutral. The exam is more appropriate for technicians, rather than systems administrators.
