 Definition

Information technology (IT) which evolved out of information and communication technology (ICT) can be said to be the architectures, methodologies, regulations and the use of computers in storing, transmitting, retrieving and manipulation of data or information programmed for various tasks.

 Jobs and careers

Job posting sites commonly use IT as a category in their databases. The category includes a wide range of jobs across architecture, engineering and administration functions. People with jobs in these areas typically have school degrees in computer science and/or information systems. They may also possess related industry certifications. Short courses in IT basics can also be found online and are especially useful for those who want to get some exposure to the field before committing to it as a career.

The following are the visible jobs in Information Technology:

Technical Support:

Tech support is generally what most non-IT folk think of when they imagine an information technology department. These types of IT experts can be known by a variety of titles—“help desk technicians,” “operations analysts,” or “problem managers”—but at the end of the day, their main job is to provide expert troubleshooting advice to clients. Technical support typically handles both hardware and software issues at the user level, helping out the less tech-savvy with their computer problems—making communication skills, problem solving, and well-rounded tech knowledge an asset.

Programmers:

Computer programmers are the brains behind software functions—they write and test the code that makes up software programs. This might range from simple computer games or word processors all the way up to complicated operating systems and database management systems. The type of skills you need typically depends on what specific area you’re programming in—but attention to detail, logical thinking, and teamwork are all assets to get this important job done right.

Web Developers:

Web developers often have the most visible jobs. They’re the ones who are responsible for building websites and the infrastructures behind them—making a careful balance of creativity and technical prowess a must for those looking to join this area of information technology.  Web developers may also be known as “web producers,” “multimedia architects,” and “internet engineers”, making their titles as diverse as their work portfolios.

Computer Systems Analyst:

Computer systems analysts are the multitaskers of information technology; they have to understand computer hardware, software, and networks—and how they all come to work together. It’s a large part of their job to make recommendations to their company for which systems are the best to use, and to tailor them to best suit their organization’s needs—including costs. This job requires a multitude of different skills, including the ability to analyze information quickly and effectively, excellent communication, and the ability to persuade when necessary.
