Which of the following is the correct abbreviation for a byte?

The abbreviation for a byte is represented by a capital "B". In the context of computer science and information technology, a byte typically consists of 8 bits, and the uppercase "B" distinguishes it from a bit, which is abbreviated as a lowercase "b". Understanding the difference between these abbreviations is crucial for interpreting data sizes correctly, especially when discussing storage capacities or data transfer rates.

The lowercase "b" represents a bit, which is the smallest unit of data in computing. Other choices like "Kb" and "MB" refer to kilobytes and megabytes, respectively, which are units that encompass multiple bytes (1 kilobyte equals 1024 bytes, and 1 megabyte equals 1024 kilobytes). Each of these units builds on the byte as a fundamental measurement of data size, but they are not the correct abbreviation for a single byte.
