Lecture 6
Telecommunications and Networking
Objectives
• Compare and contrast the major types of
networks.
• Describe the wireline communications media and
transmission technologies.
• Describe the most common methods for
accessing the Internet.
• Ref.: Chapter 6 - 8
Faculty of Information Technology Introduction to MIS
2
Computer Network
• A is a system that connects computer network
computers and other devices (e.g., printers) via
communications media so that data and
information can be transmitted among them.
Faculty of Information Technology Introduction to MIS
3
• Bandwidth refers to the transmission capacity of
a network; it is stated in bits per second.
Bandwidth ranges from narrowband (relatively
low transmission capacity) to broadband
(relatively high network capacity)
Faculty of Information Technology Introduction to MIS
4
• Broadband is wide bandwidth data transmission which
transports multiple signals and traffic types. The medium
can be coaxial cable, optical fiber, radio or twisted pair (25
Mbps for download - 4 Mbps for upload – DSL(digital
subscriber line), ADSL(Asymmetric digital subscriber line))

7
Network Fundamentals
• A is such a pathway. communications channel
It is comprised of two types of media: cable
(twisted-pair wire, coaxial cable, or fiber-optic
cable) and broadcast (microwave, satellite, radio,
or infrared)
Faculty of Information Technology Introduction to MIS
8
• Wireline media cable media or use physical
wires or cables to transmit data and information.
Twisted-pair wire and coaxial cables are made of
copper, and fiber-optic cable is made of glass.
The alternative is communication over broadcast
media or .wireless media
