An expansion
slot is a long narrow socket on the Motherboard into which different expansion
cards can be plugged in. There are three different types of expansion slots
i.e.
ISA(Industry Standard Architecture)
IT is a slow speed slot used for modems (rare to find in
modern computers).
PCI (Peripheral Component
Interconnect)
It is faster
in speed then ISA slot. It is used for sound for sound cards, graphic cards,
network card and Modems
AGP (Accelerated Graphics Port)
It is a high
speed slot used only for graphics/3d graphic cards.

Nice clear pictures of slots, I need some material to read on AGP and ISA slot. When will you post that?
Thanks

(****ISA****)
Industry Standard Architecture was the first standard for add-on components for the PC. The ISA bus was an 8-Bit or 16-Bit local bus, which connected straight on to the motherboard and into the main bus framework of the PC. As an up-grade the EISA (Extended ISA) was introduced, which had a 32-bit data bus, this obviously doubled the data exchange rate between the peripheral components. The EISA Bus could also take the old ISA cards; this was the big advantage of EISA, which used backward compatibility. Many components were designed to connect to these slots which greatly enhanced the computer capability.
(*** AGP ***)
The Advanced Graphics Port was specifically introduced to combat the data bottleneck, which was being created at the changeover point between the local PCI bus and the main data bus. In the past graphics cards connected into the PCI bus and the amount of data required for video slowed down all cards on the PCI bus. The AGP has now conquered this problem by adding a separate port and connection to the main data bus, which also run at a faster data transfer speed. Newer versions of the APG are being introduced which is speeding up the data transfer rate even more.
Thanks for the information Waqaar! I really appreciate it.
welcome forever legacy computer
