USB, short for Universal Serial Bus, is an industry standard that defines cables, connectors and communications protocols for connection, communication, and power supply between computers and devices. USB was designed to standardize the connection of computer peripherals including keyboards, pointing devices, digital cameras, printers, portable media players, disk drives and network adapters to personal computers, both to communicate and to supply electric power.

Created in the mid 1. USB Implementers Forum USB IF. OvervieweditIn general, there are three basic formats of USB connectors the default or standard format intended for desktop or portable equipment for example, on USB flash drives, the mini intended for mobile equipment now deprecated except the Mini B, which is used on many cameras, and the thinner micro size, for low profile mobile equipment most modern mobile phones. Also, there are 5 modes of USB data transfer, in order of increasing bandwidth Low Speed from 1. Full Speed from 1. High Speed from 2. Super. Speed from 3. Super. Speed from 3. USB devices have some choice of implemented modes, and USB version is not a reliable statement of implemented modes. Modes are identified by their names and icons, and the specifications suggests that plugs and receptacles be colour coded Super. Speed is identified by blue. Unlike other data buses e. Ethernet, HDMI, USB connections are directed, with both upstream and downstream ports emanating from a single host. This applies to electrical power, with only downstream facing ports providing power this topology was chosen to easily prevent electrical overloads and damaged equipment. Thus, USB cables have different ends A and B, with different physical connectors for each. Therefore, in general, each different format requires four different connectors a plug and receptacle for each of the A and B ends. USB cables have the plugs, and the corresponding receptacles are on the computers or electronic devices. In common practice, the A end is usually the standard format, and the B side varies over standard, mini, and micro. The mini and micro formats also provide for USB On The Go with a hermaphroditic AB receptacle, which accepts either an A or a B plug. On The Go allows USB between peers without discarding the directed topology by choosing the host at connection time it also allows one receptacle to perform double duty in space constrained applications. There are cables with A plugs on both ends, which may be valid if the cable includes, for example, a USB host to host transfer device with 2 ports, but they could also be non standard and erroneous and should be used carefully. The micro format is the most durable from the point of view of designed insertion lifetime. The standard and mini connectors have a design lifetime of 1,5. Mini B connectors increased this to 5,0. The micro connectors were designed with frequent charging of portable devices in mind, so have a design life of 1. Likewise, the springy component of the retention mechanism, parts that provide required gripping force, were also moved into plugs on the cable side. Historyedit. The basic USB trident logo8A group of seven companies began the development of USB in 1. Compaq, DEC, IBM, Intel, Microsoft, NEC, and Nortel. The goal was to make it fundamentally easier to connect external devices to PCs by replacing the multitude of connectors at the back of PCs, addressing the usability issues of existing interfaces, and simplifying software configuration of all devices connected to USB, as well as permitting greater data rates for external devices. A team including Ajay Bhatt worked on the standard at Intel 1. USB were produced by Intel in 1. The original USB 1. January 1. 99. 6, defined data transfer rates of 1. Mbits. Low Speed and 1. Mbits Full Speed. Microsoft Windows 9. OSR 2. 1 provided OEM support for the devices. The first widely used version of USB was 1. September 1. 99. 8. The 1. 2 Mbits data rate was intended for higher speed devices such as disk drives, and the lower 1. Mbits rate for low data rate devices such as joysticks. Apple Inc. s i. Mac was the first mainstream product with USB and the i. Macs success popularized USB itself. Following Apples design decision to remove all legacy ports from the i. Mac, many PC manufacturers began building legacy free PCs, which led to the broader PC market using USB as a standard. The USB 2. 0 specification was released in April 2. USB Implementers Forum USB IF at the end of 2. Hewlett Packard, Intel, Lucent Technologies now Nokia, NEC, and Philips jointly led the initiative to develop a higher data transfer rate, with the resulting specification achieving 4. Mbits, 4. 0 times as fast as the original USB 1. The USB 3. 0 specification was published on 1. November 2. 00. 8. Its main goals were to increase the data transfer rate up to 5 Gbits, decrease power consumption, increase power output, and be backward compatible with USB 2. USB 3. 0 includes a new, higher speed bus called Super. Speed in parallel with the USB 2. For this reason, the new version is also called Super. Speed. 2. 0 The first USB 3. January 2. 01. 0. As of 2. 00. 8update, approximately 6 billion USB ports and interfaces were in the global marketplace, and about 2 billion were being sold each year. The USB 3. 1 specification was published in July 2. In December 2. 01. USB IF submitted USB 3. USB Power Delivery 2. USB Type C specifications to the IEC TC 1. Audio, video and multimedia systems and equipment for inclusion in the international standard IEC 6. Universal Serial Bus interfaces for data and power, which is currently based on USB 2. The USB 3. 2 specification was published in September 2. Version historyeditOvervieweditRelease name. Release date. Maximum transfer rate. Note. USB 0. 8. December 1. Prerelease. USB 0.
