ELEMENTS OF INFORMATION SYSTEM

12

ELEMENTS OF INFORMATION SYSTEM

Computer Networks: A group of two or more computers linked together by

some form of cabling (fiber-optic, coaxial, or twisted wire) or by wireless technology to share data or resources such as a printer

Hardware: Physical components of a computer network

Software: Programs that instruct a computer in what to do

13

TELECOMMUNICATIONS AND NETWORKS Multimedia Communication Systems

Connected network of communication appliances; TV or Fax that may be linked to forms of mass media (such as print publications or TV programming) Examples: Fax, TV, Cell phones, printers and

photocopiers that may be linked by satellite with other remote networks

Communication Devices PDAs, GPS, cell phones

Communication Channels Wired or wireless media that make communication

possible Microwave, Satellite, underground cables, fiber optic etc

14

TELECOMMUNICATIONS AND NETWORKS

System Architecture: Location of Computer system’s elements Data entry Data processing systems

Networking Wide Area Networks (WANs): Computers linked

over long distances Local Area Networks (LANs) : Computers linked in

a smaller area, such as all of a firm’s computers within a single building

Wi-Fi (Wireless Fidelity): An access point that forms its own small network

15

TELECOMMUNICATIONS AND NETWORKS

Connecting the hardware: Modem: Device that provides a computer to computer link

over telephone wire Fiber Optic Cable: Glass fiber cables that carry data in the

form of light pulses

Client-Server Network– Clients

• The laptop or desktop computers through which users make requests for information or resources

– Servers• The computers that provide the services shared by users
