80,000,000 bits – In 1985 a 10 MB harddisk cost US$710, [5] equivalent to $2,011 in 2023. 98,304,000 bits – capacity of a high-resolution computer monitor as of 2011, 2560 × 1600 pixels, 24 bpp 50 – 100 megabits – amount of information in a typical phone book
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]
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 .
An alternative system of nomenclature for the same units (referred to here as the customary convention), in which 1 kilobyte (KB) is equal to 1,024 bytes, [38] [39] [40] 1 megabyte (MB) is equal to 1024 2 bytes and 1 gigabyte (GB) is equal to 1024 3 bytes is mentioned by a 1990s JEDEC standard. Only the first three multiples (up to GB) are ...
3 MB: A three-minute song (133 kbit/s) 650–900 MB – a CD-ROM; 1 GB: 114 minutes of uncompressed CD-quality audio at 1.4 Mbit/s; 16 GB: DDR5 DRAM laptop memory under $40 (as of early 2024) 32/64/128 GB: Three common sizes of USB flash drives; 1 TB: The size of a $30 hard disk (as of early 2024)
The ISQ symbols for the bit and byte are bit and B, respectively.In the context of data-rate units, one byte consists of 8 bits, and is synonymous with the unit octet.The abbreviation bps is often used to mean bit/s, so that when a 1 Mbps connection is advertised, it usually means that the maximum achievable bandwidth is 1 Mbit/s (one million bits per second), which is 0.125 MB/s (megabyte per ...
As MS-DOS 3.0 formatted all 16 MB-32 MB partitions in the FAT16 format, a 20 MB hard disk formatted under MS-DOS 3.0 was not accessible by MS-DOS 2.0. [27] MS-DOS 3.0 to MS-DOS 3.30 could still access FAT12 partitions under 15 MB, but required all 16 MB-32 MB partitions to be FAT16, and so could not access MS-DOS 2.0 partitions in this size range.
1976 – 1976 IBM 3350 "Madrid" – 317.5 megabytes, eight 14-inch disks, re-introduction of disk drive with fixed disk media; 1979 – IBM 3370 introduced thin-film heads, 571 MB, non-removable; 1979 – IBM 0680 Piccolo – 64.5 megabytes, six 8-inch disks, first 8-inch HDD; 1980 – The IBM 3380 was the world's first gigabyte-capacity disk ...
