Computer (Part-2)

31. How many GB are equal to 1 TB? [S.S.C. Online CHSL (T-1) 18.01.2017 (Shift-III)]

(a) 128
(b) 256
(c) 512
(d) 1024

Correct Answer: (d) 1024

Solution:Terabyte is equal to 1024 gigabytes in binary.

32. One gigabyte is equal to all of these except _________. [S.S.C. Online CHSL (T-4) 31.01.2017 (Shift-III)]

(a) 1000 megabytes
(b) trillion bytes
(c) million kilobytes
(d) one-thousandth of a terabyte

Correct Answer: (b) trillion bytes

Solution:There are trillions of bytes in 1 terabyte, while there are million kilobytes in 1 gigabyte as well as 1 GB ∼ 1000 MB and 1 TB ∼ 1000 GB
⇒ I GB ∼ $\frac{1}{1000}$ TB

33. Which of the following is not correct? [S.S.C. Online MTS (T-1) 20.09.2017 (Shift-III)]

(a) 1 TB 1024 GB
(b) 1 GB 1024 MB
(c) 1 MB 1024 KB
(d) 1 byte 1024 bits

Correct Answer: (d) 1 byte 1024 bits

Solution:Option (d) is not correct, as 1 byte contains 8 bits and not 1024 bits. The rest of the options are correct.

34. The unit of measurement of a word length is ________ . [S.S.C. Online CHSL (T-1) 15.01.2017 (Shift-III)]

(a) Meter
(b) Byte
(c) Bit
(d) Millimetre

Correct Answer: (b) Byte

Solution:The unit of measurement of a word length is a bit. The number of bits that a computer can process at a time in parallel is called its word length. The commonly used word lengths are: 8, 16, 32 or 64 bits. It is a measure of the computer power of a computer. For example, when we talk of a 32-bit computer, it means that its word length is 32 bits.

35. How many bits is equal to one byte? [C.P.O. S.I. 5.06.2016 (Shift-1)]

(a) 8
(b) 10
(c) 12
(d) 14

Correct Answer: (a) 8

Solution:A bit is represented by a lowercase b. While a byte can hold a letter or symbol, a bit is the smallest unit of storage, storing just one binary digit. The standard number of bits in a byte is 8, but that number can vary from system to system, depending on the hardware.

36. Which of the following pair is INCORRECT? [S.S.C. Online MTS (T-1) 5.10.2017 (Shift-II)]

(a) 1 KB = 8192 bits
(b) 1 KB = 8000 bits
(c) 1 MB =1024 KB
(d) 1 GB = 1024 MB

Correct Answer: (b) 1 KB = 8000 bits

Solution:1 KB =1024×8 bits = 8192 bits
1 MB = 1024 KB
1 GB = 1024 MB
Hence option (b) is wrong.

37. Which of the following has the highest storage capacity? [S.S.C. Online C.P.O.S.I. (T-1) 1.07.2017 (Shift-2)]

(a) Gigabyte
(b) Megabyte
(c) Terabyte
(d) Kilobyte

Correct Answer: (c) Terabyte

Solution:Terabyte has the highest storage capacity among the given options. Suitable options have the following storage capacity of kilobytes. It is followed by Megabyte, Gigabyte, Terabyte, Petabyte, Exabyte, Jetabyte and Potabyte respectively.

38. How is data stored in a computer? [S.S.C. Online MTS (T-1) 19.09.2017 (Shift-1)]

(a) Octal
(b) Hexadecimal
(c) Binary
(d) Decimal

Correct Answer: (c) Binary

Solution:Computers store data in binary form as it is the language that is understood by the computer.

39. Which of the following is an application protocol? [S.S.C. Online Graduation Level (T-1) 27.08.2016 (Shift-1)]

(a) HTTP
(b) TCP
(c) IP
(d) UDP

Correct Answer: (a) HTTP

Solution:HTTP is a protocol for fetching resources such as HTML documents. HTTP stands for Hypertext Transfer Protocol. It is the foundation of any data exchange on the Web and it is a client-server protocol, which means requests are initiated by the recipient, usually the Web browser.

40. HTTP in computer science stands for? [S.S.C. Online CHSL (T-1) 24.01.2017 (Shift-II)]

(a) HyperText Transmission Protocol
(b) HyperText Transfer Protocol
(c) Hyper Text Technology Protocol
(d) HyperText Total Protocol

Correct Answer: (b) HyperText Transfer Protocol

Solution:HTTP (HyperText Transfer Protocol) is an application-layer protocol used for transmitting hypermedia documents, such as HTML, over the internet. It serves as the foundation for communication on the World Wide Web and operates as a request-response protocol between clients (browsers) and servers.
