First, there are two types of prefix when talking about digital
information (read bytes): SI prefixes and binary prefixes. SI
prefixes are powers of 1,000 (1,0001, 1,0002, 1,0003, etc.): - 1
kB = 1 kilobyte = 1,0001 bytes = 1,000 bytes; - 1 MB = 1
megabyte = 1,0002 bytes = 1,000,000 bytes; - 1 GB = 1 gigabyte =
1,0003 bytes = 1,000,000,000 bytes; - and so on. As you can see,
only SI symbols mega and above are capitalized. Therefore, KB is
not a valid prefix. Binary prefixes are powers of 1,024 (1,0241,
1,0242, 1,0243, etc.): - 1 KiB = 1 kibibyte = 1,0241 bytes =
1,024 bytes; - 1 MiB = 1 mebibyte = 1,0242 bytes = 1,048,576
bytes; - 1 GiB = 1 gibibyte = 1,0243 bytes = 1,073,741,824
bytes; - and so on. As you can see here, every binary symbol is
capitalized and an lower-case i is added before the B symbol to
indicate that we are talking about kibibytes instead of
kilobytes, mebibytes instead of megabytes, etc. However, binary
prefixes are not widely used, as shown in the screenshot below.
What happens here is th
