Q5) Answer the following questions :-
It is a collection of computers and devices (which are sued for connecting to a
network) that are connected by the communication means /channels or
Networking is the connection of computers with the help of cables or wires, with an
intention of sharing information from one computer to another.
The main purpose of computer network are :-
a) Resource sharing :- The main purpose for computer network is to run all the devices
connected to it properly like printer, scanner, plotter etc. If any person in the network need to print some important document, but has no separate printer, then he/she can directly make use of the printer connected in a network. In this manner you use/ connect less devices in the network but in a cheaper mode.
b) Acts as media for communication :- The devices connected in the network plays an important role in communication like of transferring files and data to each other within
the network.
c) Reliability and availability :- If any device connected to any computer in the network is damaged/ or defective, then till the faulty device is replaced/repaired we can make use of other devices connected to other computers in the network. If incase any important file/data you need from any of the computer in the network and that computer is faulty or file/data by mistakenly gets deleted or corrupted, then you can retrieve/access the data back again from the other computer connected into a network.
d) Cost reduction :- Its very difficult/expensive for any user to purchase/use the devices (hardware or software) separately for his use but he can make use of the devices connected into the network which ever he does not have.
b) Solution:
LAN, MAN, and WAN are the different types of networks. They are been
explained in detail below :-
i) LAN :- The abbreviation of LAN is Local Area Network which means this network is
used to connect the computers and devices to each other at a very limited (small)
geographical area i.e is school computer lab, home, office building, or within a
buildings. The devices that are connected into the LAN network are called as Nodes.
By making use of cables Nodes are been connected to the LAN.
ii) MAN :- MAN stands for Metropolitan Area Network that is established in a
metropolitan area such as city or tow. A MAN typically includes one or more LAN
but covers a smaller area than a WAN. Telephone companies, cable television
operators, and other organizations makes use of MAN network.
iii) WAN :- The abbreviation of WAN is Wide Area Network which means this network
is used to connect the computers to each other who located at a very far distance
say globally. The data/information can be exchanged/transferred to each other
(computers connected into a network) all over the world. In WAN connection the
computers are connected to each other with the help of cables, telephone lines,
fibre optics, microwaves or satellites. Connecting the computers in WAN network is
a very difficult task, as there can be a probability of faults or short circuits arises if in
case the wires/cables breaks down. As compared to other networks the speed is
very low. Internet can be the perfect example of WAN.
c) Solution:
The Network Operating Systems are divided into two main categories as Peer-toPeer network and Client Server Network.
i) Peer-to-Peer network :- When two or more computers that makes use of the same
program or same type of programs in the communication and for sharing the data
is called Peer-to-Peer network. Every peer in the network in term so responsibilities
and acts as servers for the others in the network. Such type of networks always
works better in small environment. There is requirement of special management
and administration for every computers in this network. There is a limitation of 10
computers to be added within the peer-to-peer network.
ii) Client Server network :- In the network one or more computers can be servers and
other computers are known as clients. Clients requests services from the services is
known as Client/ Server Network. Novell Netware and Windows NT server are the
examples of Client/Server network.
d) Solution:
Dedicated Servers are the servers that are sued for accomplishing specific task.
e) Solution:
a) Client :- It is a computer that mostly depends on the server for each and every
resources. For ex :- a server might store a network version of network of word
processing software. Every client on the network can access the word processing
software on the server.
b) Server :- The other name for the server is the host computer that helps in
accessing and controlling of the hardwares and softwares in the network and
provides the area for storing programs, data and information. he applications, files,
printers and other information is made available when the user connects/makes
use of server. There are different types of servers which are :-
i) Dedicated Servers :- This servers are used for performing specific task.
ii) File servers :- It is used to store and manage files.
iii) Print server :- It is used to manage the printers/ adjust its settings and the
documents that are to be printed.
iv) Database server :- It is used to store database and allows/permits to access the
database.
v) Network server :- We can manage the in traffic that comes in between the
network.
vi) Web server :- It is a computer that is helps in sending/transferring the
requested web pages to the computer.
c) Connector :- The two networks are joint by the device called as a connector. Hubs,
bridges and routers are some common connectors.
f) Solution:
The difference between Lan, MAN, And WAN are as follows :-
i) LAN :- The abbreviation of LAN is Local Area Network which means this network is
used to connect the computers and devices to each other at a very limited (small)
geographical area i.e is school computer lab, home, office building, or within a
buildings. The devices that are connected into the LAN network are called as Nodes.
By making use of cables Nodes are been connected to the LAN.
ii) MAN :- MAN stands for Metropolitan Area Network that is established in a
metropolitan area such as city or tow. A MAN typically includes one or more LAN
but covers a smaller area than a WAN. Telephone companies, cable television
operators, and other organizations makes use of MAN network.
iii) WAN :- The abbreviation of WAN is Wide Area Network which means this network
is used to connect the computers to each other who located at a very far distance
say globally. The data/information can be exchanged/transferred to each other
(computers connected into a network) all over the world. In WAN connection the
computers are connected to each other with the help of cables, telephone lines,
fibre optics, microwaves or satellites. Connecting the computers in WAN network is
a very difficult task, as there can be a probability of faults or short circuits arises if in
case the wires/cables breaks down. As compared to other networks the speed is
very low. Internet can be the perfect example of WAN.
g) Solution:
The different types of hardwares that are used for network are as follows :-
i) Computer :- As we know that computers play an important role in linking with
each other in network. The users who are using the linked computers in a network
works more properly. The computers that are connected within the network does
not need to be the same. For ex :- desktop computers like IBM- compatible and
Machintosh or portable computers like notebooks, Tablet Pc are been used in the
network.
ii) Network Interface Card (NIC) :- For providing/ or making access of the computer
or other devices in a network like printer an extension/expansion card named as
NIC (Network Interface Card) is been made use. This network card acts as a bridge
between the computers and the physical medias/devices like cables by which the
data travels.
iii) Connector :- The two networks are joint by the device called as a connector.
Hubs, bridges and routers are some common connectors.
iv) Cables :- For connecting the computers and other devices in a networks, the
cables such as flexible metal or fibre optic wires are been made use of.
v) Resource :- During the processing of the program any part of the computer
system or a network such as disk drive, printer or memory must be allotted. It is
known as resource. It refers to data, information and hardware devices that can
be accessed by a group of computers through the use of shared connection.
Q6) Application Based Questions :-
Solution:
If two students are working separate computers in the school computer lab. And A
wants to see a file created by B on his computer. Yes A can access the computer of B by
making use of the Bus topology which is known as line topology.
