IT is typically used in the context of enterprise operations as opposed to personal or entertainment technologies. IT encompasses both computer technology and telephony.
The term information technology was coined by the Harvard Business Review, in order to make a distinction between purpose-built machines designed to perform a limited scope of functions and general-purpose computer machines that could be programmed for various tasks.

Computer Forensic Analyst
Network Security Analyst
The field of computer forensics is the information security branch of law enforcement and is closely related to forensic science and criminal justice work; therefore, most computer forensic analysts work for law enforcement agencies. The role of the analyst is to recover data like documents, photos and e-mails from computer hard drives and other data storage devices, such as zip and flash drives, that have been deleted, damaged or otherwise manipulated. Analysts often work on cases involving offenses committed on the Internet ('cyber crime') and examine computers that may have been involved in other types of crime in order to find evidence of illegal activity. As an information security professional, a computer forensic analyst may also use their expertise in a corporate setting to protect computers from infiltration, determine how a computer was broken into or recover lost files.

Network analysts can come from a wide range of people with computer expertise, as long as these individuals understand how computers communicate with one another and work together. They may have to work on a variety of networking systems for the Internet, Intranets, wide area networks (WAN) or local area networks (LAN). Analysts usually begin a job by asking questions of their employer and assessing their desires for the system and its functionality. For instance, in analyzing the scope of a project, they determine what hardware and software is necessary, what type of data is to be used, how the information is to be shared across a network and how the network will ultimately be configured.
The work of a network analyst is highly analytical by nature. In preparing a system, analysts may use flow charts in diagramming how computer programmers can perform system checks. They use various complex techniques of modeling data and information engineering. Analysts may need to run a series of tests in assessing the viability and troubleshooting of the systems they create.

Computer programmers write, or code, the programs that tell computers what to do. This is accomplished by converting the software program, designed by software engineers, into a series of instructions a computer can follow. The job is multifaceted in that it entails creating, adapting, modifying, troubleshooting and maintaining programs. Although having a bachelor's or master's degree is most often required for computer programming jobs, those with related work experience may only need a certificate or associate's degree. Depending on where they work, programmers may also need to seek certification.
Systems programmers develop systems that act as the computer's brains. Applications programmers develop systems that allow computers to do different jobs. According to the U.S. Bureau of Labor Statistics (www.bls.gov), job opportunities for computer programmers were projected to decline by 8% between 2014 and 2024. This is below average growth due to outsourcing of jobs since many users are now able to write their own programs. In addition, some programming functions may become automated. Programmers now often assist software engineers in a number of their duties, such as the identification of user needs and program design. The demand for programmers is highest for individuals who have good technical skills and a solid grasp of the programming needs of specific employers' businesses.
