31. 1024 kilobytes are equal to: [M.P.P.C.S. (Pre) 2016]

Correct Answer: (a) 1 megabyte
Solution:

The length of a word in computers is measured in bits.

8 Bits = 1 Byte

1024 Byte = 1 Kilobyte

1024 kilobyte = 1 Megabyte

32. One kilobyte is equal to [U.P.P.C.S. (R.I.) 2014, Uttarakhand P.C.S. (Pre) 2005, Uttarakhand P.C.S. (Mains) 2002]

Correct Answer: (c) 1024 bytes
Solution:

The length of a word in computers is measured in bits.

8 Bits = 1 Byte

1024 Byte = 1 Kilobyte

1024 kilobyte = 1 Megabyte

33. 1 kilobyte is equal to: [U.P. Lower Sub. (Mains) 2015]

Correct Answer: (d) 1024 bytes
Solution:

The length of a word in computers is measured in bits.

8 Bits = 1 Byte

1024 Byte = 1 Kilobyte

1024 kilobyte = 1 Megabyte

34. In Binary system, one kilobyte (1 KB) is equal to [U.P.P.C.S. (Mains) 2017]

Correct Answer: (a) 1024 Byte
Solution:

The length of a word in computers is measured in bits.

8 Bits = 1 Byte

1024 Byte = 1 Kilobyte

1024 kilobyte = 1 Megabyte

35. Choose the smallest memory size unit- [M.P.P.C.S. (Pre) 2015]

Correct Answer: (a) KB
Solution:

In the terms of computer 0 and 1 is known as binary digits. In short, it is also known as bits. The composition of 8 bits is known as bytes.

1 Byte = 8 bits

1 Kilobyte (KB) = 1024 Bytes

1 Megabyte (MB) = 1024 Kilobyte

1 Gigabyte (GB) = 1024 Megabyte

1 Terabyte (TB) = 1024 Gigabyte

36. Arrange the following units of measure for digital information into correct order, starting with the smallest unit first and going to the largest unit: [Rajasthan P.C.S. (Pre) 2023]

A. Kilobyte

B. Byte

C. Megabyte

D. Terabyte

E. Gigabyte

F. Bit

Correct Answer: (b) F, B, A, C, E, D
Solution:

In the terms of computer 0 and 1 is known as binary digits. In short, it is also known as bits. The composition of 8 bits is known as bytes.

1 Byte = 8 bits

1 Kilobyte (KB) = 1024 Bytes

1 Megabyte (MB) = 1024 Kilobyte

1 Gigabyte (GB) = 1024 Megabyte

1 Terabyte (TB) = 1024 Gigabyte

37. Which of the following relation is not correct? [U.P.R.O./A.R.O. (Pre) 2021]

Correct Answer: (c) 1 Gigabyte = 1024 Kilobytes
Solution:

In the terms of computer 0 and 1 is known as binary digits. In short, it is also known as bits. The composition of 8 bits is known as bytes.

1 Byte = 8 bits

1 Kilobyte (KB) = 1024 Bytes

1 Megabyte (MB) = 1024 Kilobyte

1 Gigabyte (GB) = 1024 Megabyte

1 Terabyte (TB) = 1024 Gigabyte

38. 1 MB memory is- [Uttrakhand U.D.A/LDA (mains) 2006]

Correct Answer: (a) 1024 Kilobytes
Solution:

In the terms of computer 0 and 1 is known as binary digits. In short, it is also known as bits. The composition of 8 bits is known as bytes.

1 Byte = 8 bits

1 Kilobyte (KB) = 1024 Bytes

1 Megabyte (MB) = 1024 Kilobyte

1 Gigabyte (GB) = 1024 Megabyte

1 Terabyte (TB) = 1024 Gigabyte

39. In computer language how many bytes are there in one megabyte? [M.P.P.C.S. (Pre) 2005]

Correct Answer: (d) 10,48,576
Solution:

I megabyte = 1024 kilobyte

= 1024 × 1024 byte

= = 10,48,576 byte (approx. 1.05 million bytes)

40. A million bytes is approximately- [M.P.P.C.S. (Pre) 2008]

Correct Answer: (c) Megabyte
Solution:

I megabyte = 1024 kilobyte

= 1024 × 1024 byte

= = 10,48,576 byte (approx. 1.05 million bytes)
