memory capacity
Storage capacity refers to the recording capacity of a memory, a storage medium or a data carrier.
The storage capacity is specified in bits, characters or bytes (B). Since the storage capacity of hard disks, flash memories or other memories is usually millions or billions of characters, this number is represented by a prefix. A distinction must be made here between the generally used prefixes and those standardized in IEC 60027-2, because these specifications are always a power of "2". Thus, a kilobyte( KB) is `2^10` and thus 1,024. According to the IEC standard, this prefix is called Kibi and the corresponding storage capacity Kibibyte (KiB). The same applies to the megabyte( MB), which is defined by the International Electrotechnical Commission (IEC) as MebiByte (MiB), or the terabyte( TB), which is called Tebibyte.
In modern surveillance technology and Big Data, we are talking about amounts of data measured in zettabytes(ZB) or even yottabytes(YB) and used as a resource.
