COMMUNICATION SYSTEMS
4. INFORMATION SYSTEM
An Information System (IS) is a collection of people, hardware, software,
Communication devices, network and data resources organised to collect,
Process, store and distribute data and information within an organisation for a specific purpose.
Types of information System
There are two major types of information system, which are:
1. Data Processing System: This refers to a set of programs used to process, organise and manipulate large amounts of data used daily in organizations for transacting business, e.g. Computerised billings system used by PHCN, accounting payroll systems like Peachtree and Tally, Word Processing Systems like Microsoft Word, etc.
2. Global Positioning System (GPS): This consists of a group of orbiting satellites in space that transmit signals to GPS receivers on earth, which can provide information regarding the exact location of a person or item, c.g a car using a GPS enabled device.
Satellite communication provides a communication link between two or more with the help of satellites. Radio wave signals are beamed or transmitted from an earth based station towards the satellite orbiting in space; the satellite points on the earth. It involves the transfer of signals between sender and receiver amplifies the signal and retransmits it back to the receiver ‘s antenna present on the earth’s surface. This sending can be done at the same time or after some delay.
