(a) PLX Devices
(b) NVIDIA Corporation
(c) ENOcean Private Company
(d) INTEL Corporation

Correct Answer: (d) INTEL Corporation

Solution:Intel purchased the rights from Nippon Calculating Machine Corporation and launched the Intel® 4004 processor and its chipset with an advertisement in the November 15, 1971, issue of Electronic News:

"Announcing a New Era in Integrated Electronics." That's when the Intel® 4004 became the first general- purpose programmable processor on the market-a "building block" that engineers could purchase and then customize with software to perform different functions in various electronic devices.

42. A/an________ is a central server on a computer network that enables connected clients to access the server's storage capacities. [S.S.C. Online CHSL (T-I) 16.10.2020 (Shift-III)]

(a) application server
(b) file server
(c) print server
(d) web server

Correct Answer: (b) file server

Solution:A file server is a central server instance in a computer network that enables connected clients to access the server's storage capacities. The term encompasses both the hardware and software needed to implement such a server.

43. Related to computers, what is 'Wetware'? [S.S.C. Online Graduation Level (T-1) 31.08.2016 (Shift-2)]

(a) Computer programs
(b) Circuitry
(c) Human brain
(d) Chemical storage devices

Correct Answer: (c) Human brain

Solution:Wetware is a term drawn from the computer-related idea of hardware or software but applied to biological life forms. Here the prefix "wet" is a reference to the water found in living creatures. Wetware is used to describe the elements equivalent to hardware and software found in a person, namely the central nervous system (CNS) and the human brain.

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)]

(a) Octal
(b) Binary
(c) Hexagonal
(d) Triad

Correct Answer: (b) Binary

Solution: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)]

(a) 1101000
(b) 1101010
(c) 1100110
(d) 1110000

Correct Answer: (b) 1101010

Solution: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)]

(a) 1100101
(b) 1100111
(c) 1101001
(d) 1101011

Correct Answer: (a) 1100101

Solution: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).

48. In the following list of devices which device is used in datalink layer? [S.S.C. Online Graduation Level (T-1) 30.08.2016 (Shift-III)]

(a) Repeaters
(b) Routers
(c) Application gateway
(d) Bridge

Correct Answer: (d) Bridge

Solution:According to the OSI model, seven layers are used to define the internal workings of the communication system of a network. The data link layer is found between the physical and network layers. Bridge is used in this layer.

Correct Answer: (d) Connecting two networks

Solution: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.
