A control bus is a computer bus that is used by the CPU to communicate with devices that are contained within the computer. This occurs through physical connections such as cables or printed circuits.
The CPU transmits a variety of control signals to components and devices to transmit control signals to the CPU using the control bus. One of the main objectives of a bus is to minimize the lines that are needed for communication. An individual bus permits communication between devices using one data channel. The control bus is bidirectional and assists the CPU in synchronizing control signals to internal devices and external components. It is comprised of interrupt lines, byte enable lines, read/write signals and status lines.
When the CPU writes data to the main memory, it transmits a signal to the write command line. The CPU also sends a signal to the read command line when it needs to read. This signal permits the CPU to receive or transmit data from main memory.
A data bus is a computer subsystem that allows for the transferring of data from one component to another on a motherboard or system board, or between two computers. This can include transferring data to and from the memory, or from the central processing unit (CPU) to other components. Each one is designed to handle so many bits of data at a time. The amount of data a data bus can handle is called bandwidth.
A typical data bus is 32-bits wide. This means that up to 32 bits of data can travel through a data bus every second. Newer computers are making data buses that can handle 64-bit and even 96-bit data paths. At the same time they are making data buses to handle more bits, they are also making devices that can handle those higher bitrates.
An address bus is a computer bus architecture used to transfer data between devices that are identified by the hardware address of the physical memory (the physical address), which is stored in the form of binary numbers to enable the data bus to access memory storage.
The address bus is used by the CPU or…
