What Are Expansion Slots in Computer?

Computers have come a long way since they were first invented. The first computers were large, expensive and hard to use.

Today, computers are smaller, cheaper and easier to use. But one thing has not changed, the need for expansion slots.

Expansion slots are necessary because they allow you to add more features and capabilities to your computer. For example, if you want to add a printer or a scanner to your computer, you will need an expansion slot.

There are different types of expansion slots, the most common being PCI (Peripheral Component Interconnect) and AGP (Accelerated Graphics Port). PCI slots are used to add devices such as printers, scanners and modems.

AGP slots are used to add video cards.

Most computers come with one or two PCI slots and one AGP slot. If you want to add more than two devices or add a high-end video card, you will need an expansion card that plugs into an available slot.

Expansion slots are a necessary part of any computer system. They allow you to expand the capabilities of your computer by adding new devices.
