While talking about this technology, people often confuse it with a casino slot which is completely something different.

The first expansion card of slot-type was Altair 8800, which is added to themicrocomputer. For hardware simulation, the old expansion cards also have built-in hard disk cards, clock cards, calendar cards and compatibility cards.Usually, the opening of the expansion slot is on the back of a PC. It offers an electrical link to the motherboard for an expansion card. For extra security purpose,thebolts were used to attach the card to the slot.

Some computer system has a mixture of PCI and PCI Express slots.

  1. AGP:

AGP stands for accelerated graphic ports and it is a speedy point to point channel. It is used to attach a video card to the computer system. You can solve the complex operations like texture mapping with the help of this AGP card because it can access the system memory.
