5. What is a Computer Network ?
• A network can be defined as the communication between two
hosts using intermediate network devices and some form of
connectivity.
• The main purpose of this communication is to share available
information and resources.
• Data originates from one sending End device, flows through the
network and arrives at the receiving End device.

6. Hosts (End devices)

7. Intermediate Devices
Hub
Bridge
Switch
Router
Repeater
Wireless Access
Point
These are the network devices which help to interconnect End hosts together

8. Components of a network
NIC Cables Operating System
Protocols

9. Local Area Networks (LAN / WLAN)
 A local-area network can connect many computers in a relatively small geographical area
such as home, an office or a campus
 It allows users to access high bandwidth internet, share information and devices

10. Metropolitan Area Network
A network spread between multiple non contiguous buildings within the
single metropolitan area

11. Wide Area Network
• A network that connects two or more local-area networks over a potentially large
geographic area

12. How communication takes place
• All connected devices require a method of communication which
are called network protocols
• Without protocols, devices would lack the ability to understand
the electronic signals they send to each other over network
connections
• Network protocols serve these basic functions:
• address data to the correct recipient(s)
• physically transmit data from source to destination, with security protection if
needed
• receive messages and send responses appropriately

15. What is Switching ?

16. What is Routing?
• Routing is the process of moving packets from one host to another host
in a network, or between or across multiple networks.
• It is usually performed by dedicated devices called Routers.
• Routers don’t just route traffic to other networks, they learn which are
the fastest routes and use them first.
• Also there are many different routing protocols available to use
according to the type of network or the organization’s need.
