Some of the details about the given examples of Information Technology are as follows:
• Computer Software - this is a collection of computer programs and related data that provide instructions for a computer to decipher what to do and how to do it. It is a collection of computer programs, procedures and associated documentation that is concerned with the operation of the data processing system. The term can be contrasted to hardware, which is the physical devices that make up a computer.
• Information systems - this is an academic discipline that joins the business field with computer science to create a new scientific area of study. It is supported by theoretical foundations of informations and computations so that scholars can explore various business models as well as related them to computational algorithmic processes. An Information Systems discipline focuses functionality rather than design.
• Computer hardware - the hardware found within a computer is the physical components that make up the structure of the device. Software can then be installed upon this hardware to make the computer run. Typically a computer will contain an abundance of hardware that includes, but is far from limited to, a mother board, CD-Rom drive and sound cards.
• Programming languages - these are artificial languages designed to be used within Information Technology to express computations that can be performed by a machine. These languages can be used to create programs that control the behavior of a machine and to express algorithms precisely.
These examples are just a few of the ways Information Technology can be used. In the modern world, more and more used of IT are being discovered and created all the time.
