2.  A computer network is a group of
interconnected computers.
 First Network : The Advanced Research
Projects Agency (ARPA) funded the design
of the "Advanced Research Projects
Agency Network" (ARPANET) for the
United States Department of Defense.

3.  Network topology is the pattern of
interconnection between computer in a
network. Network topology shows the
physical layout of a network and shows
links between them.
There are following types of topologies
prevalent across different networks.

4.  Bus Topology
 Star Topology
 Ring Topology
 Mesh topology
 Tree Topology

5.  One wire connects all nodes.
 Terminator ends the wires.
Advantages:
Easy to setup
Small amount of wire
Disadvantages:
Slow
Easy to crash

6.  All computers connected to a hub
 Packets sent to hub
 Hub sends packet to destination
Advantages:
 Easy to setup
 One cable can not crash network
Disadvantages:
One hub crashes all network.
Uses lots of cable

7.  Nodes connected in a circle
 Tokens used to transmit data
 Nodes must wait for token to send
 Advantages
 Time to send data is known
 No data collisions
 Disadvantages
 Slow
 Lots of cable

8.  Each node relays data for the network.
All mesh nodes cooperate in the distribution
of data in the network.
Advantages:
 Data will always be delivered
 Easy to trouble shoot
Disadvantages:
 Lots of cable
 Hard to setup

9.  Combines characteristics of linear bus and star topologies.
It consists of groups of star-configured workstations
connected to a linear bus backbone cable.
 Advantages
 Easy to add new devices.
 Easy to remove any branch
Disadvantages:
 More cable.
 One branch fail may fail all network.

10.  Any computer which satisfies its all available
facilities to all other computers of a network
( likes – access of files , communication ,
printing etc.) is termed as server.

11.  The most common component of a LAN is the
workstation. A workstation is an individual.
Single user microcomputer with
communications capabilities added.

12.  A cable is two or more wires running side by
side and bonded, twisted, or braided
together to form a single assembly

13.  Twisted-pair cabling
 Coaxial cable
 Fiber-optic cable

14.  Hubs also called wiring concentrators , provide a
central attachment point for network I cabling.
 In general, a hub refers to a hardware device that
enables multiple devices or connections to be
connected to a computer.
Hubs can be divided into
three types :
Passive hubs
Active hub
Intelligent hub

15. AnA network interface card (NIC) is a circuit board
or card that is installed in a computer so that it can be
connected to a network. ter(NIC) is a circuit bo A n
A network interface card provides the computer with a
dedicated, full-time connection to a network. etwor

the computer with a dedicated, full-time
connection to a network ard or is installed
in a computer so that it can be connected
to a net

16. A network switch (also called switching hub,
bridging hub, officially MAC bridge) is a computer
networking device that connects devices together
on a computer network, by using
packet switching to receive, process and forward
data to the destination device.
