44. Which of the following language is used by computer to process data? [S.S.C. Online C.P.O.S.L. (T-4) 5.07.2017 (Shift-2)]

Correct Answer: (b) Binary
Note:

The computer uses binary language to interpret data. A computer is a machine and only a numeric language is understood. Thus, whatever information we process in the computer, is stored in 0 and 1.

45. Convert decimal number 106 to binary. [S.S.C. Online CHSL (T-1) 21.01.2017 (Shift-3)]

Correct Answer: (b) 1101010
Note:

Step 1: Divide (106) successively by 2 until the quotient is 0:

106/2 = 53 remainder is 0

53/2 = 26 remainder is 1

26/2 = 13 remainder is 0

13/2 = 6 remainder is 1

6/2 = 3 remainder is 0

3/2 = 1 remainder is 1

1/2 = 0 remainder is 1

Step 2: Read from the bottom (MSB) to top (LSB) as 1101010.

So, 1101010 is the binary equivalent of decimal number 106 (Answer).

46. Convert decimal number 101 to binary. [S.S.C. Online CHSL (T-1) 18.01.2017 (Shift-2)]

Correct Answer: (a) 1100101
Note:

Step 1: Divide (101) 10 successively by 2 until the quotient is 0:

101/2 = 50 remainder is 1

50/2 = 25 remainder is 0

25/2 = 12 remainder is 1

12/2 = 6 remainder is 0

6/2 = 3 remainder is 0

3/2 = 1 remainder is 1

1/2 = 0 remainder is 1

Step 2: Read from the bottom (MSB) to top (LSB)

as 1100101. So, 1100101 is the binary equivalent of decimal number 101 (Answer).

47. defines data types and the relationships among them. [S.S.C. Online CHSL (T-1) 30.01.2017 (Shift-II)]

50. What is a bridge used for in a computer network? [S.S.C. Online MTS (T-I) 17.09.2017 (Shift-1)]

Correct Answer: (d) Connecting two networks
Note:

Bridges are used to connect two subnetworks that use interchangeable protocols. It combines two LANs to form an extended LAN. The main difference between the bridge and repeater is that the bridge has a penetrating efficiency.

A bridge accepts all the packets and amplifies all of them to the other side. The bridges are intelligent devices that allow the passing of only selective packets from them. A bridge only passes those packets addressed from a node in one network to another node in the other network.
