Where is external data bus?
motherboard
The external data bus connects the processor to adapters, the keyboard, the mouse, the hard drive, and other devices. An external data bus is also known as an external data path. You can see the external data lines by looking between the expansion slots on the motherboard.
What is external bus controller?
The external bus interface, usually shortened to EBI, is a computer bus for interfacing small peripheral devices like flash memory with the processor. It is used to expand the internal bus of the processor to enable connection with external memories or other peripherals.
What is DMA explain its function?
Direct memory access (DMA) is the process of transferring data without the involvement of the processor itself. It is often used for transferring data to/from input/output devices. A separate DMA controller is required to handle the transfer. The controller notifies the DSP processor that it is ready for a transfer.
What is a local bus?
Also called the “system bus,” a local bus is the pathway between the CPU, memory and peripheral controller chips. The term was popular in the early 1990s with the introduction of the VESA local bus (see VL-bus). See bus and PC data buses. Local Bus. Peripheral controller cards plug into slots on the local bus.
What is external interface?
(1) A connection to a device outside the computer’s cabinet. Contrast with internal interface. (2) A connection to the WAN side of a router. The WAN may be a public or private network. Contrast with internal interface.
What is external hardware?
External hardware components, also called peripheral components, are those items that are often externally connected to the computer to control either input or output functions. These hardware devices are designed to either provide instructions to the software (input) or render results from its execution (output).
What is buses in computer and its types?
A computer bus is also known as a local bus, data bus, or address bus, a bus is a link between components or devices linked to a computer. A bus, for instance, carries data through the motherboard between a CPU (Central Processing Unit) and the system memory.
