From Wikipedia, the free encyclopedia

In a computer or data transmission system, to reset means to clear any pending errors or events and bring a system to normal condition or initial state usually in a controlled manner. It is usually done in response to an error condition when it is impossible or undesirable for a processing activity to proceed and all error recovery mechanisms fail. A computer storage program would normally perform a "reset" if a command times out and error recovery schemes like retry or abort also fail.

The ability for an electronic device to be able to reset itself in case of error or abnormal power loss is an important aspect of embedded system design and programming. This ability can be observed with everyday electronics such as a television, audio equipment or the electronics of a car, which are able to function as intended again even after having lost power suddenly. A sudden and strange error with a device might sometimes be fixed by removing and restoring power, making the device reset. Some devices, such as portable media players, very often have a dedicated reset button as they are prone to freezing or locking up. The lack of a proper reset ability could otherwise possibly render the device useless after a power loss or malfunction.

A soft reset is performed by restarting system software without resetting the hardware.

reset is also an Windows Terminal Server command. The syntax is RESET { SESSION }.

In addition, reset is a BSD/Linux/UNIX command to restore a console to a normal state. This command is an alias of the tset terminal initialization command. [1]
