What is the expansion bus Crystal?

The expansion bus runs at the speed of the system clock. The expansion bus crystal sets the speed for the expansion bus.

What is expansion bus?

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.

What is the function of expansion bus?

Expansion buses are used to connect devices to the motherboard using the motherboard’s data bus. They allow the flow of data between that device and other devices in and connected to the computer. Early computers moved data between devices and the processor at about the same rate as the processor.

What is the most common expansion bus?

PCI and PCI Express are common expansion buses in computers.

Why do we need expansion buses?

The expansion bus allows the CPU to communicate with peripheral devices. Expansion bus and associated slots are required because basic PC system cannot satisfy all needs of users. Expansion bus slots or I/O bus designs in general, provide the opportunity to add more devices to PC.

Which statements about the expansion bus is true?

Motherboards

What are expansion bus slots?

In computing, an expansion card (Also called expansion board, adapter card or accessory card) is a printed circuit board that can be inserted into an electrical connector, or expansion slot (also referred to as a bus slot) on a computers motherboard, backplane or riser card to add functionality to a computer system.

What is the difference between PCIe bus and expansion bus?

Peripheral Component Interconnect Express (PCIe or PCI-E) is a serial expansion bus standard for connecting a computer to one or more peripheral devices. PCIe provides lower latency and higher data transfer rates than parallel busses such as PCI and PCI-X. PCI Express slots on a motherboard.

What is the difference between a system and an expansion bus?

System Bus vs Expansion Bus Summary: Difference Between System Bus and Expansion Bus is that system bus, also called the front side bus (FSB), is part of the motherboard and connects the processor to main memory. While an expansion bus allows the processor to communicate with peripherals.

Which bus connects the CPU and expansion boards?

PCI(Peripheral Component Interconnect): PCI Bus connects the CPU and expansion boards such as modem cards ,network cards and sound cards. These expansion boards are normally plugged into expansion slots on the motherboard. That’s why PCI bus is also known as expansion bus or external Bus.

Which of the following is not part of the expansion bus?

PROM stands for Programmable Read Only Memory and is not a type of expansion slot or bus design. Today, PCI has become the most used expansion slot design in PCs. Older PCs incorporated both PCI and ISA slots for computability with older expansion devices.

How does the expansion bus crystal set the system clock?

The expansion bus crystal sets the speed of the system clock. A separate expansion bus crystal enables the expansion bus to run at a different speed than the frontside bus.

What is the name of the expansion bus?

B) The expansion bus crystal sets the speed of the system clock. C) The CPU communicates with RAM via the expansion bus. D) The frontside bus is another name for the expansion bus. The expansion bus crystal sets the speed of the system clock.

What was the speed of the IBM expansion bus?

In the original IBM PC, that speed was about 14.318 MHz ÷ 2, or about 7.16 MHz. The latest expansion buses run much faster, but remember that old speed of roughly 7 MHz; as you learn more about expan- sion slots, you’ll see that it’s still needed on even the most modern systems. PC Bus

Which is faster the expansion bus or the CPU?

IBM settled on a standard expansion bus speed of about 7 MHz—faster than the CPU! (This was the only occurrence in the history of PCs that the expansion bus was faster than the CPU.) This expansion bus was called the PC busor XT bus.
