Expansion Card

Tags:

An expansion card is added on card, simply card, inner card, software adapter, or development board. Extension card can be card or an electric table included in to the expansion slot of the PC or other non-laptop to provide a brand new capability, like the ability for connecting to a different computer-using a network cable to that pc.
 

Even vacuum-tube based computers had modular construction, but individual functions for peripheral devices filled a cabinet, not just a printed circuit board. Processor, memory and I/O cards became feasible with the development of integrated circuits.

 

Expansion cards allowed a processor system to be adapted to the needs of the user, allowing variations in the type of devices connected, additions to memory, or optional features to the central processor (such as a floating point unit). Minicomputers, starting with the PDP-8, were made of multiple cards, all powered by and communicating through a passive backplane.
