For example, a processor with 65,536 bytes of cache memory might be said to have "64 K" of cache. In this convention, one thousand and twenty-four kilobytes (1024 KB) is equal to one megabyte (1 MB), where 1 MB is 1024 2 bytes.
5,242,880 bits (640 kibibytes) – the maximum addressable memory of the original IBM PC architecture megabyte (MB) 8,000,000 bits (1,000 kilobytes) – the preferred definition of megabyte: 8,343,400 bits – one "typical" sized photograph with reasonably good quality (1024 × 768 pixels). 2 23: mebibyte (MiB) 8,388,608 bits (1,024 kibibytes ...
In this convention, one thousand and twenty-four megabytes (1024 MB) is equal to one gigabyte (1 GB), where 1 GB is 1024 3 bytes (i.e., 1 GiB). Mixed 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 .
In the original IBM PC, the basic RAM limit is 640 KB. This is to allow for hardware addressing space in the upper 384 KB (upper memory area (UMA)) of the total addressable memory space of 1024 KB (1 MB).
4096 bytes = 4 KiB: A memory page in x86 (since Intel 80386) and many other architectures, also the modern Advanced Format hard disk drive sector size. 4 kB: About one page of text from a novel; 120 kB: The text of a typical pocket book; 1 MiB: A 1024×1024 pixel bitmap image with 256 colors (8 bpp color depth) 3 MB: A three-minute song (133 ...
The 5.25-inch diskette sold with the IBM PC AT could hold 1200 × 1024 = 1 228 800 bytes, and thus was marketed as "1200 KB" with the binary sense of "KB". [40] However, the capacity was also quoted "1.2 MB", [ 41 ] which was a hybrid decimal and binary notation, since the "M" meant 1000 × 1024.
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). [1]
