Information is data which is changed into meaningful output. Technology on the other hand refers to the use of hardware and software to meet the requirements of the system.
Information technology describes the equipments used to capture, store, transmit or present information. some of the technologies required capture store transmit and present information include: computer, communication, data, application systems.
COMPUTER: these are the type of hardware processors which will be required to change the input into some meaningful output . also it should be remembered that there are important peripheral devices that can be connected to these systems such as scanner, camera, and microphone to add value to them .
TYPE OF COMPUTER:
Mainframes: have traditionally been used for decades and have vast
processing and data handling systems , and can incorporate a number of central processing.
Mini computer: are similar in nature to mainframes they tend to be more robust and do not require high technical mainframe or their own specialized environment as mainframe do ,therefore they tend to have a lower initial capital and maintenance cost.
Microcomputer: or PC systems are increasingly being used by the modern business and individual users as the main method of interface with their information. It consists of a monitor,Central processing .
Laptops: or notebooks are a portable version of PC s and often have exactly the same processing capabilities as PC s but having the major advantage of being portable.
DATA :the development of a centralised database via a communication link would help to improve the access.
Data capture is the point at which the data enters the system(optical character recognition, mark reader ,bar coding , microphone and speakers, magnetic swipe.)
Data processing : in computer science is the analysis and organization of data by the repeated use of one or moire computer programs. Data processing is used extensively in business , engineering and science
