Answer 1

Explanation:

An expansion bus is a computer bus which moves information between the internal hardware of a computer system (including the CPU and RAM) and peripheral devices. It is a collection of wires and protocols that allows for the expansion of a computer.

Answer 2

Answer:

An expansion bus is an assortment of wires that allows for computer expansion with the use of an expansion board, a printed circuit board inserted into an expansion slot on the motherboard or backplane that provides additional features to a computer system.

An expansion bus provides an input/output pathway for transferring information between internal hardware, such as RAM or the CPU, and expansion devices such as a graphics card or sound card

There are several different types of expansion buses with diverse features, such as:

Industry Standard Architecture (ISA)

Accelerated Graphics Port (AGP)

Peripheral Component Interconnect (PCI)

PCI Express (PCI-X)

One of the early types of expansion buses was the ISA, which was used with IBM-compatible computers. It supported a network card, video card or additional serial ports. However, the ISA bus had a tendency for bottlenecks and was replaced by the PCI bus
