The Basics of Information Technology

Software

Software can be defined as the set of instructions for the computer - it dictates what is to be done. Software runs on (i.e. operates on) hardware. A list of instructions that undertakes a particular requirement or task is known as a "program." The two major categories of software are "system software" and "application software." System software is made up of control programmes for the computer itself, such as the operating system and database management system (DBMS). Application software is any programme that processes data for the user (e.g. inventory, payroll, spreadsheets, word processors, etc.).

Often people confuse software with data however it is not data - it tells the hardware how to deal with the data - in simple terms software is "run" (i.e. a set of instructions is initiated) and data is then processed. The data itself often comes in the form of databases - which are files that are originated and managed by a database management system (DBMS). DBMSs can manage data in many different formats such as text, sound, images and video Database and file structures are determined by the software being used.

Required Equipment and Connections for setting up a basic PC workstation

You need to, at least, budget for the cost of an entry (beginner) level PC with some basic software such as Microsoft Works, a printer and a scanner.

Your Internet connection via a high-speed line (in this example, DSL) would involve the cost of a modem plus the ISP's costs. This type of standard starter pack should suffice in most startup situations and the facilities can always be "ramped up" should demand increase.
