Usb - or Universal Serial Bus technology has come to be a widespread, simple, cheap way of connecting all kinds of devices. Its popularity has come about extremely swiftly as the history of Usb only stretches back to the mid-1990s. This article gives an overview of Usb technology, its history and its future.
History:

Usb technology was industrialized in order to present a thorough means by which devices, particularly computer-related devices, could interconnect and communicate. It was created by a collaboration of Intel, Compaq, Microsoft, Digital, Ibm, and Northern Telecom. In the early days of the Ibm Pc, there were a myriad of connections for dissimilar types of devices including, At, serial, parallel, joystick, Scsi & Ps/2. None of these ports were compatible with each other & each served essentially the same function. Enter Usb. Not only did Usb give one interface, it provided power for some devices and it enabled users to plug a large whole of devices into one machine.
Pre-releases of the Usb thorough came in 1994 with the final Usb 1.0 specification being released to market in November 1995. The thorough was improved upon in September 1998 with Usb 1.1 which many of the problems identified in the customary thorough were fixed.
Usb could work at 1.5 or 12 mbps but with competition from Firewire & with technology placing greater demands on bandwidth, Usb 2.0 released in August 2000, could handle speeds of 480mbps.
Adoption:
All connectors face an adoption question and Usb was no different. There is only a market for a expedient that is interconnectable if there are other devices in the market that it can connect to. These network corollary can hamper the adoption of every expedient (if you are the only someone with a telephone, it's not much use but if you're one of millions with the same, standardised system, the increased market for the thorough makes it more affordable and more provocative to others).
Usb was given a real boost by the iMac which offered Usb ports only & no inheritance option. This meant that there was a market where Usb could gain a foothold.
The Present:
Usb devices accomplish many functions extremely well. Devices can be hot-swapped - that is they could be connected & disconnected without it being primary to reboot a Pc. Devices from many thousands of manufacturers can intercommunicate, many devices can be installed without a exact expedient driver, some devices can be connected to computers without the need for an external power furnish and others can recharge by being connected via a Usb device.
Usb connectors are robust in that they do not rely on pins that are easy to bend or break. Usb cables are designed so that static electricity is discharged before a connection is made manufacture the thorough more durable.
The connections are extremely usable & it is easy to connect Usb devices or to realise that you have the wrong end of the cable. By design, the cables are easy to attach & remove - there is no need for screws - meaning that they are surely accessible by all.
Future:
The hereafter for Usb is the Usb 3.0 thorough that will work at 4.8 gbps, ten times the current rate. This new thorough will only be backwards-compatible with Usb 2.0 but will include some power conservation features. Increased speed & better power consumption will help Usb compete with the other standards on the market along with Firewire 800 & eSata.
To put the doing of the new Usb thorough into perspective, currently, it would take 15 minutes to copy a 27gb high definition film; the new thorough will mean that this can be ended in 70 seconds.
The Usb thorough is extremely usable and durable & it has massive popularity. Many movable 'phones have a Usb connection & Usb Flash drives make the transfer of large amounts of data an extremely simple process. A subculture of Usb gadgets has sprung up in recent years with weird & wacky devices like Usb fridges, vacuums, toasters, slippers & back massagers all hitting the market to massive amounts of interest and varying degrees of success. It is provocative that whilst it was the brainchild of a whole of clubs along with Microsoft & Intel it was Apple that gave Usb its popularity. Windows machines did not deal well with Usb even as late as Windows 98 but the iMac showed how Usb devices could be used to give a great deal of collection through extreme simplicity.
