1 MB = 1 024 000 bytes (= 1000×1024 B) is the definition used to describe the formatted capacity of the 1.44 MB 3.5-inch HD floppy disk, which actually has a capacity of 1 474 560 bytes. [5] Randomly addressable semiconductor memory doubles in size for each address lane added to an integrated circuit package, which favors counts that are ...
In computer architecture, 512-bit integers, memory addresses, or other data units are those that are 512 bits (64 octets) wide. Also, 512-bit central processing unit (CPU) and arithmetic logic unit (ALU) architectures are those that are based on registers , address buses , or data buses of that size.

On a disk that uses 512-byte sectors, a 512-byte cluster contains one sector, whereas a 4-kibibyte cluster contains eight sectors. A cluster is the smallest logical amount of disk space that can be allocated to hold a file.
File size is a measure of how much data a computer file contains or how much storage space it is allocated. Typically, file size is expressed in units based on byte . A large value is often expressed with a metric prefix (as in megabyte and gigabyte ) or a binary prefix (as in mebibyte and gibibyte ).
The correct meaning was often clear from the context; for instance, in a binary-addressed computer, the true memory size had to be either a power of 2, or a small integer multiple thereof. Thus a "512 megabyte" RAM module was generally understood to have 512 × 1024 2 = 536 870 912 bytes, rather than 512 000 000.
A partition type 0x04 indicates this form of FAT16 with less than 65,536 sectors (less than 32 MB for sector size 512). The benefit of FAT16 was the use of smaller clusters, making disk usage more efficient, particularly for large numbers of files only a few hundred bytes in size.
