Learning Objectives

At the end of the session a student will be able to:

List and describe the stages of evolution of

telecommunications and data networks

Describe and explain the major networking architectures

Describe the key components of the major networkingarchitectures

Describe the status of contemporary networking solutions

Explain with an example the basic concepts of a client-

server networking paradigm


3/19

Telecommunication

Science of communicating over long distanceusing telephone or radio technology

Use microelectronics (small semiconductor chips)

and PC tech.

Transmit, receive, and switch voice, data and video

Using different transmission media (copper, fiber,

electromagnetic transmissions)


4/19

Telephony

Traditional voice communication

Use telephones

All telephones and subscribers share the

telephone network

Thus constrained by peak load

LAN

Consists of a shared transmission medium and

a set of hardware and software for interfacing

devices to the medium and regulating the

orderly access to the medium Topologies: ring, bus, tree, and star

Usually owned by the organization using the

network to interconnect equipment
