slots and types of slots of mother board ,what is mean of slots what is use of lots ,how to configure slots to mother board ,how we can identifies slot with different mother board so you will get all kind of information about slots so dont forget to read go ahead click here for LIVE CHAT

Industry Standard Architecture (ISA):

This type of slot is the oldest still in use today. If you open up an old 286, you’ll see a few of these. An 8-bit ISA slot is capable of 0.625MB/sec transfer rate between the card and the motherboard. Later versions of this slot were 16-bit, capable of 2MB/sec. This is still slow compared to today’s standards, but cards such as modems do not require anything faster than this. If you look at your motherboard’s slots, the longer black ones are the ISAs. If they are all one size, they are all ISA.

This type of slot is not used very often in desktop machines. It is used mainly in servers, or computers that host networks. With such a computer, the demands placed on its components are too big for ISA to handle. Also, the EISA bus is capable of bus mastering, which allows components attached to the bus to talk to each other without bothering the CPU.

Micro Channel Architecture (MCA):

Not too common either, this bus was created by IBM. It is 32-bit, like EISA, but you can’t stick ISA cards into it. MCA was capable of bus mastering, plus it could look at other devices plugged into it and identify them, leading to automatic configuration. MCA also produced less electrical interference, reducing errors. MCA is history. Don’t get it. Nobody uses it.

Video Electronics Standard Association (VESA):

This used to be considered a very fast interface made up mainly for video cards of the time that demanded a little more bandwidth. The VESA-Local Bus, or VL-Bus, is connected straight to the CPU’s own internal bus, hence the name “local”.

Peripheral Component Interconnect (PCI):

PCI was developed by Intel, like the VL-Bus. It is different than the VL-Bus except that it runs at the same speed. There is a fast interface unit between the card and the CPU that does the talking. This unit made the bus independent of the CPU. The dependency was a drawback of the VL-Bus, which was limited to the 486. Also, you can plug cards into it without any configuring.

Personal Computer Memory Card International Association (PCMCIA):

This is a special socket in which you can plug removable credit-card size devices. These circuit cards can contain extra memory, hard drives, modems, network adapters, sound cards, etc. Mostly, PCMCIA cards are used for laptops, but many PC vendors have added PCMCIA sockets to their desktop machines.

Accelerated Graphics Port (AGP):

AGP is a more recent bus technology designed specifically for graphics cards. The bus sits directly on the system front side bus, giving it direct access to the CPU and the system memory. This means it is not hampered by the slower speeds of the PCI bus.
