There are many different types of computer certifications. Some certifications demonstrate that a person understands how general computer hardware and operating systems operate, as well as how to maintain them. Other certifications are for software and hardware created by a specific technology manufacturer and supported by a private entity rather than a neutral body. Another type of computer certification relates to knowledge of various web design technologies. Finally, there are computer certifications for networking technologies, maintaining computer security, and combating cybercrime.
Some computer certifications are for computer hardware and software maintenance and repair. While there are certifications for specific hardware manufacturers, the CompTIA A+® certification is a widely recognized computer certification that is recognized by many organizations. This certification focuses on understanding the fundamentals of computer hardware. The computer certification’s overall goal is to show that the certified technician understands personal computer hardware, how to identify problems with it, and how to repair it. This certification also verifies a basic understanding of commonly used computer operating systems, as well as how to configure and test them.
A vendor-specific computer certification refers to a technology or technologies developed and maintained by a specific commercial or non-commercial entity. Apple Inc., for example, offers a variety of computer certifications, some of which are for demonstrating competency with specific Apple software and others for performing maintenance on their proprietary hardware. Furthermore, Cisco Systems, a computer networking company, supports a variety of computer certifications relating to their many networking technologies, including voice communications and security infrastructure. While there are generalized computer certifications for topics like computer maintenance and networking, many information technology vendors offer specialized certifications that demonstrate various levels of competency with their hardware and software.
There are also website design certifications that demonstrate knowledge of various aspects of website design and implementation. Certifications in web development languages such as hypertext markup language and cascading style sheets, for example, can help a professional demonstrate proficiency. Other design computer certifications may cover vendor-specific technologies like Adobe® Flash®, as well as advanced combinations of a variety of design techniques.
Networking and security are two additional computer certification categories. Certifications in computer networking usually cover the configuration and management of various network systems and devices, such as wireless devices and the coordination of large-scale computer backups and installations. There are also numerous computer security certifications available, ranging from computer forensics to securing large corporate networks.
