With the invention of USB, the computer have became more flexible in that devices can be added to augment performance without requiring the use of an expansion card. In 2005, both PCI and AGP were replaced with PCI Express. The AGP bus was designed specifically for video. This was followed by the AGP bus in 1997. Intel launched their PCI slot as replacement for ISA in 1991. Following on Altair-8800’s debut, Intel began manufacturing expansion slots on a large scale for use in the corporate sector. The very first computer with expansion capabilities, the Altair-8800, was introduced in 1975. The adoption of expansion cards occurred rapidly in the computing world because of the ability for users to customize performance. The basic purpose of expansion cards is to enhance the existing abilities of the motherboard. For example, video graphics cards are used to enhance the video quality on a computer.Įxpansion cards are also known as add-on cards or interface cards. Just because something is supported by the chipset, doesn’t mean the.

Many different classes of expansion card are available, including sound cards, video graphics cards, network cards and so on.
