MCQs
| 1. | ______ represents 4 bits or half a byte of memory. (OSSC BSSO 2022) | |
| A. | Binary | |
| B. | Nibble | |
| C. | Hexa | |
| D. | Gigabyte | |
Answer: Option B
Explanation:
4 bits = 1 nibble. So the answer is nibble.
8 bits = 1 byte. So 4 bits = half a byte = nibble.
Other useful information:
Bit/Binary digit = 0 (or) 1
4 bits = 1 nibble
8 bits = 1 byte
1024 bytes = 1 kilobyte (KB)
1024 kilobytes = 1 megabyte (MB)
1024 megabytes = 1 gigabyte (GB)
1024 gigabytes = 1 terabyte (TB)
1024 terabytes = 1 petabyte (PB)
1024 petabytes = 1 exabyte (EB)
1024 exabytes = 1 zettabyte (ZB)
1024 zettabytes = 1 yottabyte (YB)
| 2. | The smallest unit of memory in a computer is (MPPSC AE 2022) | |
| A. | Megabyte | |
| B. | Nibble | |
| C. | Byte | |
| D. | Bit | |
Answer: Option D
Explanation:
Bit/Binary digit = 0 (or) 1
4 bits = 1 nibble
8 bits = 1 byte
1024 bytes = 1 kilobyte (KB)
1024 kilobytes = 1 megabyte (MB).
So megabyte > byte > nibble > Bit. So bit is the smallest.
| 3. | 1 Petabyte (PB) = 1024 ______ (SSC CHSL 2020) | |
| A. | Zettabytes (ZB) | |
| B. | Exabytes (EB) | |
| C. | Terabytes (TB) | |
| D. | Gigabytes (GB) | |
Answer: Option C
Explanation:
1024 terabytes = 1 petabyte (PB). So terabytes is the answer.
Other useful information:
Bit/Binary digit = 0 (or) 1
4 bits = 1 nibble
8 bits = 1 byte
1024 bytes = 1 kilobyte (KB)
1024 kilobytes = 1 megabyte (MB)
1024 megabytes = 1 gigabyte (GB)
1024 gigabytes = 1 terabyte (TB)
1024 terabytes = 1 petabyte (PB)
1024 petabytes = 1 exabyte (EB)
1024 exabytes = 1 zettabyte (ZB)
1024 zettabytes = 1 yottabyte (YB)
| 4. | Arrange the following units of memory in ascending order:(Allahabad High Court Group D Mains 2023) A. Megabyte B. Gigabyte C. Kilobyte D. Petabyte E. Terabyte Choose the most appropriate answer from the options given below: | |
| A. | B, C, A, D, E | |
| B. | C, B, A, D, E | |
| C. | C, A, B, E, D | |
| D. | C, B, D, A, E | |
Answer: Option C
Explanation:
1024 bytes = 1 kilobyte (KB)
1024 kilobytes = 1 megabyte (MB)
1024 megabytes = 1 gigabyte (GB)
1024 gigabytes = 1 terabyte (TB)
1024 terabytes = 1 petabyte (PB)
So ascending order will be kilobyte < megabyte < gigabyte < terabyte < petabyte.
So the answer is C, A, B, E, D.
| 5. | 1024 GB is equivalent to: (MP Patwari 2017) | |
| A. | 1 TB | |
| B. | 1 GB | |
| C. | 1 PB | |
| D. | 1 MB | |
Answer: Option A
Explanation:
1024 gigabytes = 1 terabyte (TB). So 1 TB is the answer.
Other useful information:
Bit/Binary digit = 0 (or) 1
4 bits = 1 nibble
8 bits = 1 byte
1024 bytes = 1 kilobyte (KB)
1024 kilobytes = 1 megabyte (MB)
1024 megabytes = 1 gigabyte (GB)
1024 gigabytes = 1 terabyte (TB)
1024 terabytes = 1 petabyte (PB)
1024 petabytes = 1 exabyte (EB)
1024 exabytes = 1 zettabyte (ZB)
1024 zettabytes = 1 yottabyte (YB)
