Correct Answer: (e) None of these
Solution:

Router, Switch, and Hub, all are connecting devices. MPPCS considered this question as bonus in their answer key.

2. A ........ is used to transfer data packets between two computer networks. [M.P.P.C.S. (Pre) 2021]

Correct Answer: (b) Router
Solution:

A network switch connects devices within a network (often a local area network or LAN) and forwards data packets to and from those devices. Switches send packets directly to devices, rather than sending them to networks like a router does.

A router is a networking device that forwards data packets between computer networks. Routers perform the traffic directing functions on the Internet. Data sent through the Internet, such as a web page or email, is in the form of data packets.

A brouter (also known as the bridging router) is a device that combines features of both bridge and router. Working as a router, it is capable of routing data packets across networks and working as the bridge, it is capable of filtering local area network traffic.

A computer gateway in a network examines the data packet and then passes it to the other network. It checks compatibility between the two networks and then converts the data packet to ensure that it can be transmitted between them.

3. To increase the length of a network without loss of signal strength, we would use- [M.P.P.C.S. (Pre) 2008]

Correct Answer: (a) Repeater
Solution:

The repeater is a networking component that extends the length of a network by amplifying the signal so that it can travel further along the cable without any loss.

4. Celeron, Pentium, and Core series are of- [R.A.S./R.T.S.(Pre) 2013]

Correct Answer: (c) Computer processor
Solution:

Celeron, Pentium, and Core are the series of computer processor.

5. ROM is a memory- [Uttrakhand U.D.A./LDA (Mains) 2006]

Correct Answer: (a) To read only
Solution:

ROM means Read-only memory. Once data has been written onto a ROM chip, it cannot be removed and can only be read. Unlike main memory RAM (Random-access memory), ROM retains its contents even when the computer is turned off. ROM is referred to as being non-volatile, whereas RAM is volatile.

6. In a computer, the permanent memory is called- [U.P.P.C.S. (Mains) 2012, Uttarakhand Lower Sub. (Pre) 2010]

Correct Answer: (b) ROM
Solution:

ROM is considered as the permanent memory of computer. Data or information in ROM is not destroyed or erased even after the computer is turned off.

7. A means of specifying location of data in memory is called- [Uttarakhand Lower Sub. (Pre) 2010]

Correct Answer: (b) Address
Solution:

A means of specifying location of data in memory is called address.

8. CD ROM stands for: [Uttarakhand P.C.S. (Mains) 2002]

Correct Answer: (b) Compact Disc Read Only Memory
Solution:

CD-ROM (Compact Disc Read-Only memory) is a type of optical disc. Normally CD-ROMs are already mounted and cannot be erased and filled with new data. The CD-ROMs can hold up to 700 MB data.

9. In computer terminology, RAM stands for- [Uttarakhand P.C.S. (Pre) 2002-03]

Correct Answer: (b) Random Access Memory
Solution:

RAM is an acronym for random-access memory. It is considered as temporary memory and works only when the computer is functioning. Once the computer is switched off, all the data which is stored in RAM are lost or erased.

10. A name for the short term memory of the computer that is lost when the computer is turned off- [U.P. Lower Sub. (Mains) 2013]

Correct Answer: (d) RAM
Solution:

RAM is an acronym for random-access memory. It is considered as temporary memory and works only when the computer is functioning. Once the computer is switched off, all the data which is stored in RAM are lost or erased.
