Fundamentals of Information Technology seeks to provideyou with an understanding of the uses of computers. The

course additionally aims to endow you with practical skills ofusing a word processor, a spreadsheet, the Internet, and anoperating system, efficiently.


5/13

View the following pictures and formulate a definition of theterm information technology.

Introduction to computers and information technology


6/13

Information Technology (IT), is the term used to describethe equipment, hardware and computer programs (software),that allows us to access... and present data and information(Gay and Blades, 2005).


Information Technology is the integration of variouscomputing tools used for information processing withintodays society. It is mostly an adventure into how weconduct business and how we live our lives (Long, 2005).

Additionally, we can view IT as a field of study in which welearn how best to remain competitive in society withinventions; as well as attain vocational and life-lasting skillsto use these inventions.


7/13

Technically, a computer is any counting device; morespecifically, it is

...an electronic device capable of interpreting andexecuting programmed commands for input, output,

computation, and logic operations (Long, 2005).


Consequently, we can consider the computer system as a setof components that interact to achieve a common goal.The purpose, therefore, of a computer system is to use

all its working components to produce quality information.

9/13

A computer system has only four fundamental components:Inputhandles the gathering of data

Processingtransformation of data to information

Outputhandles the dissemination of processed data

Storagesafe keeping of information for future use


Note: The computer system (and not the computer) is madeup of four components.


10/13

An input device is any peripheral device that allows one toenter data or instructions into a computer.



11/13

An output device is any peripheral device that conveysinformation to one or more individuals.


Highlight three outputdevices that are

commonly used today.


12/13

The processor is the electronic component that interpretsand carries out instructions to operate the computersystem (which resides on the motherboard).



13/13

Storage components hold data, instruction, as well asinformation for future use; these items are kept onstorage media (which are housed within the system unit).
