What Is Information Technology (IT)?

Information technology (IT) is the design, development, implementation, support and management of computer-based information systems, including software applications and computer hardware. Increasingly important across all business sectors, IT uses computers and software to convert, store, protect, process, transmit, and securely retrieve information.

IT professionals perform a variety of duties that range from installing applications to designing complex computer networks and information databases. Other areas of information technology include data management, networking, engineering computer hardware, database and software design, as well as the management and administration of entire systems. 

What Topics Do IT Courses Cover?

With a wide range of software and specializations to choose from, IT courses address a diverse set of training topics. Here are just a few you might cover in your IT training course:

Systems Design and Software Development

The design and development of systems is the process of defining the hardware and software architecture, components, modules, interfaces, and data for a system to satisfy specified requirements. It also includes requirements analysis, system design, implementation, documentation, and quality assurance. Systems design and development is also often referred to as systems engineering, SDD, and more generally IT development. 

IT Security

Hackers are getting smarter, which means IT professionals need to stay one step ahead. Since businesses are increasingly reliant on IT to support their activities, this makes them ever more vulnerable to threats from malicious software like ransomware, spyware, and viruses or even their own staff.

IT security courses will get you up-to-date on the latest software developments which can make the difference between success and failure for your business. IT security training costs far less than the cost an organisation can suffer due to a significant breach.

Network and System Administration

Responsible for the day-to-day operation of computer networks, a Network and System Administrator organizes, installs, and supports an organization's computer systems. These can include local area networks (LANs), wide area networks (WANs), network segments, intranets, and other data communication systems.

Certification in the appropriate products is usually required by all companies because it validates the IT professional's knowledge and use of best practices.
