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
