The industry (which is made up of employers and professionals) mutually recognize the importance of skills validation. Skills validation through certification exams is a standard way of checking the foundation or advanced knowledge and proficiencies of the candidate. CompTIA is the currently known provider of certain Information Technology professional certifications. Its former name was the Association of Better Computer Dealers, Inc. (ABCD). It is a non-profit trade association (or five microcomputer dealerships that banded together) and was organized in 1982. It changed its name to Computer Technology Industry Association (CompTIA) to project its evolving role in the computer industry, not only in the United States but globally as well.
The CompTIA certification exam now includes the CompTIA Linux Certification. This is administered through Pearson VUE and Prometric testing centers. Linux certification is a validation of the knowledge in Linux operating systems. IT professionals with between six months to one year of practical experience using Linux are qualified to take the certification examination. Your Linux operational expertise is tested in the following areas: installation, configuration, hardware, documentation, management, security, and trouble shooting for the Linux operating system on workstations and servers. A revision in the exam contents was made in 2005 to adjust to the expanding range of Linux job tasks. Some notable additions and improvements are in the areas of security and documentation. And to answer criticisms about the excessive amount of questions regarding hardware-related concerns, there is now lesser emphasis made on the topic in the revised edition.
With this said revision, the CompTIA Linux certificate holder is now expected to be better (based on performance and productivity.) The CompTIA Linux exams are vendor neutral and are aimed more at technicians rather than systems administrators.
