Alternatively described as a bus slot or expansion port, one expansion slot is link or port situated inside a computer system on the motherboard or riser plank that allows a computer hardware development card to be connected. Because that example, if you want to download a new video map in the computer, you’d purchase a video expansion card and install the card into the compatible expansion slot.

You are watching: Which of the following expansion buses are most commonly used for video cards in older computers

Many the the belowexpansion map slots room obsolete.You’re most likely only walk to conference AGP, PCI, and PCI Express when working with computers today. In the snapshot belowis an example of what growth slots may look prefer on a motherboard. In this picture, there are three different types of growth slots: PCI Express, PCI, and also AGP.

PCI – Network card, SCSI, Sound card, video cardPCI Express – video cardAGP – video clip cardISA – Network card, Sound card, video clip cardAMR – Modem, Sound cardCNR – Modem, Network card, Sound cardEISA – SCSI, Network card, video clip cardVESA – video card


PCI Express: The best kind of development slot to have actually in your computer is the PCI Express, additionally written together PCIe. Without boring you, the PCI Express kind of growth slot communicates v the motherboard, and also therefore v the microprocessor, both quickly and also efficiently.

PCI: The PCI slot is the most common form of internal expansion for a PC.

some PCs have a mixture of PCI and also PCI to express slots. If so, go with PCI Express once you have actually that option.

AGP: This form of growth slot was especially designed to address graphics adapters. In fact, AGP was standing for sped up Graphics Port. Larger PCs may sport this expansion slot, however the best video clip cards use PCI Express.

ISA: The most ancient form of growth slot is the ISA, which represents (get this) market Standard Architecture. That’s due to the fact that it never really had actually a name until another, far better type of development slot came along. ISA slot hang around to be compatible v older expansion cards.
