Information Technology (IT) – Computer, internet mobile phone and satellite systems that speed up communication and the flow of information

To remember the meaning of the term Information Technology, use the following mnemonic:

Information used to arrive slowly but technical knowledge (information technology) has now allowed us to speed up communications.

IT services include:

• The provision and setting up of hardware (the machines and devices) and software (the programs, or sets of instructions, that run on the hardware);
• The configuring of networks (an organisation's network infrastructure typically includes its internet connectivity and internal networking between computers and other devices, such as printers);
• Mobile device management (laptops, tablets, payment terminals and mobile phones);
• Cloud computing (storage and access of information on remote computers, which guards against data loss);
• Cyber security (hardware and software that guards against attacks on systems by hackers who might steal or destroy data, or plant computer viruses.)
