When b is 2, the unit is the shannon, equal to the information content of one "bit". A system with 8 possible states, for example, can store up to log 2 8 = 3 bits of information. Other units that have been named include: Base b = 3 the unit is called "trit", and is equal to log 2 3 (≈ 1.585) bits. [3] Base b = 10
One hour of SDTV video at 2.2 Mbit/s is approximately 1 GB. Seven minutes of HDTV video at 19.39 Mbit/s is approximately 1 GB. 114 minutes of uncompressed CD-quality audio at 1.4 Mbit/s is approximately 1 GB. A single-layer DVD+R disc can hold about 4.7 GB. A dual-layered DVD+R disc can hold about 8.5 GB. A single-layer Blu-ray can hold about ...
2 0: bit: 10 0: bit 1 bit – 0 or 1, false or true, Low or High (a.k.a. unibit) 1.442695 bits (log 2 e) – approximate size of a nat (a unit of information based on natural logarithms) 1.5849625 bits (log 2 3) – approximate size of a trit (a base-3 digit) 2 1: 2 bits – a crumb (a.k.a. dibit) enough to uniquely identify one base pair of DNA
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 ...
The Xbox One S is available in 500 GB, 1 TB, and a "special edition" 2 TB model, which originally retailed at US$299, $349, and $399 respectively. The 2 TB model was released on August 2, 2016, [105] [336] and 1 TB and 500 GB models were released on August 23, 2016. [337] A Gears of War 4 special edition was also released. [338]
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 .
Memory bandwidth is the rate at which data can be read from or stored into a semiconductor memory by a processor. Memory bandwidth is usually expressed in units of bytes/second , though this can vary for systems with natural data sizes that are not a multiple of the commonly used 8-bit bytes.
Since then, the increase in density has matched Moore's Law, reaching 1 Tbit/in 2 in 2014. [2] In 2015, Seagate introduced a hard drive with a density of 1.34 Tbit/in 2, [3] more than 600 million times that of the IBM 350. It is expected that current recording technology can "feasibly" scale to at least 5 Tbit/in 2 in the near future.
