MCQs
| 1. | Group of 4 bits forms (RRB ALP 2019) | |
| A. | Byte | |
| B. | Nibble | |
| C. | Gigabyte | |
| D. | Terabyte | |
Answer: Option B
Explanation:
4 bits = 1 nibble. So the answer is 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. | In the context of memory size in computer data storage, one gigabyte is equal to how many megabytes? (SSC CHSL 2020) | |
| A. | 64 MB | |
| B. | 32 MB | |
| C. | 1012 MB | |
| D. | 1024 MB | |
Answer: Option D
Explanation:
1024 megabytes = 1 gigabyte (GB). So the answer is 1024 MB.
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)
| 3. | The largest unit of data measurement among the following is (UPPCL ARO 2018) | |
| A. | Gigabyte | |
| B. | Terabyte | |
| C. | Exabyte | |
| D. | Petabyte | |
Answer: Option C
Explanation:
1024 megabytes = 1 gigabyte (GB)
1024 gigabytes = 1 terabyte (TB)
1024 terabytes = 1 petabyte (PB)
1024 petabytes = 1 exabyte (EB)
So exabyte is the largest unit of data measurement.
| 4. | BIT is also known as _____. (SSC CPO 2017) | |
| A. | Binary language | |
| B. | Binary digit | |
| C. | Binary Number | |
| D. | Gigabyte | |
Answer: Option B
| 5. | ________ is the smallest unit of data in a computer. (SSC CHSL 2019) | |
| A. | Gigabyte | |
| B. | Terabyte | |
| C. | Bit | |
| D. | Byte | |
Answer: Option C
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)
1024 megabytes = 1 gigabyte (GB)
1024 gigabytes = 1 terabyte (TB)
So terabyte > gigabyte > byte > bit. So bit is the smallest.
