答案:
1 mark for
- A tebibyte = 1024 gibibytes / 1048576 kibibytes / $2^40 bytes whereas a gigabyte = 1000 megabytes / 1 000 000 kilobytes / $10^9 bytes
- Tebi is binary prefix giga is denary prefix
讲解:这道题主要是让我们答出 tebibyte 和 gigabyte 的区别。
- 1 TiB = 1024 GiB (Gibibytes), 1 GiB = 1024 MiB (Mebibytes), 1 MiB = 1024 KiB (Kibibytes), 因此 1 TiB = $2^40 字节
- 1 GB = 1000 MB (Megabytes), 1 MB = 1000 KB (Kilobytes), 因此 1 GB = $10^9 字节。
