MCQs
| 1. | 1 yotta byte = ______ (UGC NET 2023) | |
| A. | 1024 Terabytes | |
| B. | 1024 Exabytes | |
| C. | 1024 Zettabytes | |
| D. | 1024 Petabytes | |
Answer: Option C
Explanation:
1024 zettabytes = 1 yottabyte (YB). So 1024 zettabytes 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)
| 2. | For a Computer, BIT stands for (NTPC 2017) | |
| A. | Binary Digit | |
| B. | Built-in Integer | |
| C. | Binary Task | |
| D. | Binary Integer Transfer | |
Answer: Option A
| 3. | Select the smallest (computer) memory size ? (CISF Constable/Tradesmen 2021) | |
| A. | Terabyte | |
| B. | Gigabyte | |
| C. | Kilobyte | |
| D. | Megabyte | |
Answer: Option C
Explanation:
1024 bytes = 1 kilobyte (KB)
1024 kilobytes = 1 megabyte (MB)
1024 megabytes = 1 gigabyte (GB)
1024 gigabytes = 1 terabyte (TB).
So terabyte > gigabyte > megabyte > kilobyte.
So kilobyte is the smallest memory size.
| 4. | How many terabytes make one petabyte ? (SSC CHSL 2021) | |
| A. | 1024 | |
| B. | 1048 | |
| C. | 1084 | |
| D. | 1042 | |
Answer: Option A
Explanation:
1024 terabytes = 1 petabyte (PB). So 1024 terabytes make one petabyte.
