 peripheral devices exist such as printers, modems, graphics scanners, text scanners, code readers, magnetic card readers, external monitors, voice command interfaces, external storage devices, and so on. Despite the reductions in size, computer terminals still must physically interface with the peripheral devices. This typically involves either the running of a cable from one of the computer terminal to each device (hereinafter “hard-wiring”) or the computer terminal must be docked with the device while the information transfer is to take place.
Hard-wiring poses several problems. If there are many peripheral devices, there must be as many cables attached to the computer terminal. This place a strain on the input/output capabilities of many computer devices. In addition, the wired mass of cabling often creates an eyesore and safety hazard. In addition, attempts to hide cabling behind walls often proves very costly, and such hidden wires are always more difficult to relocate.
Another problem exists when several computer terminals share a peripheral device. Not only must each computer be connected, often via hard-wiring, to the peripheral device, but it must utilize a communication protocol for sharing the communication channel to the peripheral device with the other connected computer terminals. This poses significant problems with different types of computers that do not share a common hard-wired interface or communication protocol.
In smaller computer terminal settings, hand-held or portable terminals, the cabling and connection problem become more severe. For example, excess cabling can transform an otherwise light, portable device into either a stationary device or a heavy, luggable device having dangerous trip cords for cabling.
Physical connections created by hard-wiring often proves to be relatively expensive because cables break and must be replaced. Cable replacement is even more common in portable environments where cables are subject to frequent handling, temperature extremes, dropping and other physical trauma.
An operator who is using, holding or carrying several devices and feels all tied up is not just inconvenienced, he may be severely limited in his mobility and flexibility as he moves about the work area. This loss of mobility and flexibility directly undercuts the entire reason for having small and portable computers and peripheral devices, and greatly increases the likelihood of operator injury.
Attempts to alleviate or eliminate these problems have been made but have not been greatly successful. One solution is to incorporate a computer terminal and all of the peripherals into one unit. However, this solution proves unsatisfactory for several reasons. For example, the incorporation of many devices into one unit greatly increases the

Despite the reduction in size, computer terminals however must physically interface with the peripheral devices.

 Another problem exists when several computer terminal share a peripheral device. Not only must each computer be connected, frequently via hard - wiring, to the peripheral device, but it must use a communication protocol for share the communication channel to the peripheral device with the other connected computer terminals. This poses significant trouble with different types of computers that do not share a coarse hard - wire interface or communication protocol. 
 In smaller calculator terminal settings, hand - held or portable terminal, the cabling and joining problem become more severe. For example, excess cabling can transform an otherwise unaccented, portable device into either a stationary device or a heavy, luggable device have dangerous trip cords for cabling.
