What are the most common expansion buses today?

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)

What is common bus?

The basic computer has eight registers, a memory unit, and a control unit . Paths must be provided to transfer information from one register to another and between memory and registers. A more efficient scheme for transferring information in a system with many registers is to use a common bus. ...

What is a bus expander?

Bus expanders are computer boards or cable systems that connect to other interface boards, using only one I/O slot while remaining compliant with the bus standard. Bus expanders allow increased bus loads across all buses while maintaining the integrity of legacy firmware and software.

Is cache a memory?

cache memory, also called cache, supplementary memory system that temporarily stores frequently used instructions and data for quicker processing by the central processing unit (CPU) of a computer. The cache augments, and is an extension of, a computer's main memory.

What are expansion slots?

Definition of expansion slot

: a socket on the motherboard of a computer into which an expansion card may be inserted.

What is a RAM?

Random access memory (RAM) is a computer's short-term memory, which it uses to handle all active tasks and apps. None of your programs, files, games, or streams would work without RAM. Here, we'll explain exactly what RAM is, what RAM means, and why it's so important.

How a common bus system can be constructed?

A bus can be constructed using multiplexer which enable a sets of registers to share a common bus for data transfer. The select lines S1 and S0 indicate which of four register will have its contents transferred to the bus.

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.

What is the difference between system bus and expansion bus?

The system bus supports the CPU, RAM, and other motherboard components. The system bus runs at speeds that support the CPU. The expansion bus supports any add-on devices via the expansion slots and runs at a steady 7.16 MHz.

What is the function of expansion bus?

Functions of Expansion Bus :

Expansion bus slots are long thin connectors provided on motherboard near backside of computer and these are used to connect all add-on cards in a computer system. They provide direct electrical connection with PC's main logical circuitry.
