Which of the following slots on a motherboard are best for a video card?
Each correct answer represents a complete solution. Choose two.

A.
PCIe

B.
PCI

C.
AGP

D.
EISA

Explanation:

AGP and PCIe are the best slots for a video card.
PCI Express (PCIe), also known as 3rd Generation I/O (3GIO), is a type of computer bus. It is a new
I/O bus technology that has more bandwidth than PCI and AGP slots. It uses two low-voltage
differential pairs, at 2.5Gb/s in each direction. It is designed to replace PCI and AGP expansion slots.
The bus is available in several different bus widths: x1, x2, x4, x8, x12, x16, and x32. PCIe is able to
transfer data in
both directions at a time. PCIe hardware will work on operating systems that support PCI.
AGP is a high speed 32-bit bus designed for high performance graphics and video support. It allows a
video card to have direct access to a computer’s RAM, which enables fast video performance. AGP
provides a bandwidth of up to 2,133 MB/second.
Answer option D is incorrect. The Extended Industry Standard Architecture (EISA) is a 32-bit PC
expansion bus designed as a superset of a 16-bit ISA bus. The EISA bus is designed to increase the
speed and expand the data width of the legacy expansion bus while still supporting older ISA cards.
EISA slots are obsolete now.
Answer option B is incorrect. PCIe and AGP slots are better than PCI slot for a video card.
