Computer Networks Class 7 MCQ with Answers and Explanations:

(1) The process of exchanging information, data etc from one computer to another.

(a) Computer communication        b) Migration           c) Translation         d) None of these

Explanation :-  The process/way of exchanging or transferring of information, data, instructions etc form one computer to the other is to be termed as Computer Communication. Previously only the bigger computers had the only abilities to communicate with each other but nowadays even the smaller computers and devices can communicate with each other by making use of computer networks.

 

(2) The connection of computers which are communicated to each other through various communication channels.

(a) Computer network             b) Internet                     c) E-mail                    d)  None of these

Explanation :-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.

 

(3) The inclusion of physical devices that are connected in a network.

(a) Network hardware b) Internet                     c) E-mail                    d)  None of these

Explanation :- Network hardware is the inclusion of physical devices which are used in a network. The devices can be a Computer, NIC card, Connector, Cables etc.

 

(4) NIC stands for

(a) Not In Connection

b) Network Interface Card

c) New Instruction Card

d) Newly Inserted Card

Explanation :-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.

 

(5) The device that is used for joining the two networks together.

(a) Bridges b) Routers                                c) Joiner                        d) Connector

Explanation :-  In the networking Connector is the device that connects two networks together. It acts just similar to the bridge, the is connected at both the ends of the river passing through it. Routers, hubs, bridges etc are some commonly used connectors.

 

(6) A flexible metal or fibre-optic wire that is sued connect computers and other devices in the network.

(a) Connectors       b) Cables                          c) NIC cards                      d) Internet

Explanation :-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.

 

(7) The process of allocation of computer system or network at the time of processing of a program.

(a) Hubs         b) Resources                    c) NIC                         d) All of these

Explanation :-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.

 

(8) This network connects the computers and the devices in a limited geographical area such as home, school, building etc.

(a) LAN                         b) WAN                        c) WLAN                     d) MAN

Explanation :-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.

 

(9) This network includes one or more LAN’s but covers a small geographic area as compared to WAN.

(a) LAN            b) WAN                        c) WLAN                     d) MAN

Explanation :-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.

 

(10) This network is used to connect the computers at a very far distance say globally.

(a) LAN            b) WAN                             c) WLAN                          d) MAN

Explanation :-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.

 

(11) The structure of the computers that are connected to each other in a network.

(a) Topology                        b) Maps                              c) Graphs                        d) Routes

Explanation :-The outline structure of the computers and the devices that are connected to each other in the computer network. Star, Ring , Bus etc are some examples of network topologies.

 

(12) In this topology, the computers are connected to each other in a round (circle) shape

a) Ring                             b) Bus                              c) Star                              d) None of these

Explanation :-In the Ring topology, the computers are connected to each other with cables in a closed loop form. The computers and devices are connected to each other in a round like ring shape.

 

13) The group of computers that sues the same program/ same type of programs for the purpose of communicating and sharing of data.

(a) Global network

b) WAN

c) Client server network

d) Peer-to-Peer network

Explanation :-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.

 

(14) Host computer is the other name

(a) Client       b) Server                              c) IBM                           d) Machintosh

Explanation :-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 :-

Dedicated Servers b)  File servers    c) print server     d)  database server    e) Web server f)  network server

 

15)  This computer depends on the server computer for each and every resources

(a) Client           b) Server                              c) IBM                           d) Machintosh

Explanation :-Client 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.
