 Introduction to Computer Networks (Class 10 SEBA)

Important Questions Answer

1. What is computer network?

Ans: A computer network is a set of computer and other units that are connected with each other. In a computer network information can be stored among connected computers.

For example if there is a printer connected to the network that Printer can be used by all the computers of the network.

2. Give some example of wire technologies.

Ans: Some example of wire technologies are Coaxial Cable, Twisted Pair Cable and Optical Fibre Cable.

3. Give some example of wireless technologies.

Ans: Some example of wireless technologies are Wi-Fi, Bluetooth and WiMAX.

4. Classify the type of computer network based on connecting technology.

Ans: Base on the connecting technology the computer network is divided into three types. They are : wired, wireless and hybrid.

5. Classify the type of computer network based on the size of the network.

Ans: Base on the size of the network computer network is divided into four types. They are : 

       PAN : Personal Area Network

       LAN : Local Area Network

       MAN : Metropolitan Area Network

       WAN : Wide Area Network.

6. What is the graphical range of PAN?

Ans: The graphical range of PAN is 10.

7. What is Leased Telecommunication Circuits?

Ans: Leased Telecommunication Circuit is a communication line between two or more location functioning according to a commercial contract.

8. What are nodes?

Ans: Nodes are the peripheral devices or computer in a computer network.

9. How can you refer to a computer in a computer network?

Ans: We can refer to a computer in a computer network by its Hostname, IP address or MAC address.

10. What is Hostname?

Ans: The hostname name is the name of the computer or any connected device in a computer network.

11. Give a brief comparison between different type of computer network.

Ans: 

PAN	LAN	MAN	WAN
PAN's ownership is private. Normally one pen is owned by a single person.	LAN's ownership is private that is everyone can create their LAN by connecting multiple devices.	MAN's ownership may or may not be private. That is MAN may not be owned by one organisation.	WAN's ownership is not private. Most of the time WANs are owned by multiple organisation.
The Data transferred rate of PAN is very high	The Data transfer rate of a LAN is slower than PAN	The Data transferred rate of MAN is slower than LAN	The Data transfer rate of WAN is slower than MAN
There is no congestion in PAN since data lines are not shared	There may be a little congestion in LAN. The congestion depend upon the number of communication device	Normally the congession in a MAN is more than that of LAN	In WAN, there is more congestion than MAN, LAN and PAN.
There is no design issue in PAN and maintenance is easy.	LAN's design and maintenance are easy	MAN's design and maintenance are more difficult than LAN	WAN's designs and maintenance are more difficult than LAN as well MAN

12. What is the full form of IP address?

Ans: The full form of IP address is Internet protocol address.

13. What is IP address? Name two type of IP address.

Ans: An internet protocol address is a numerical level that is assign to network device to identify them uniquely.

The two type of IP address are internet protocol version 4 (IPv4) and internet protocol version 6 (IPv6).

14. What is the length of IPv4 and IPv6?

Ans: The length of IPv4 address is 32 bit and the length of IPv6 is 128 bit.

15. Differentiate between IPv4 and IPv6.

Ans: i) The length of IPv4 address is 32 bit where as the land of the IPv6 is 128 bit.

     ii) IPv4 address are most often written in dot decimal notation which  contain fourth segment of 8 bit
