What is an external bus on a computer?
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 the function of the bus in a computer?
A bus is a high-speed internal connection. Buses are used to send control signals and data between the processor and other components. Three types of bus are used. Address bus – carries memory addresses from the processor to other components such as primary storage and input/output devices.
What is internal and external bus?
An internal bus enables the communication between internal components, such as a video card and memory. An external bus is capable of communicating with external peripherals, such as a USB or SCSI device.
What is bus in digital system?
A bus is a subsystem that is used to connect computer components and transfer data between them. A “bus topology” or design can also be used in other ways to describe digital connections. A bus may be parallel or serial. Parallel buses transmit data across multiple wires.
What is power bus?
A bus in a power system is defined as the vertical line at which the several components of the power system like generators, loads, and feeders, etc., are connected. These quantities are the magnitude of the voltage, the phase angle of the voltage, active or true power and the reactive power.
Why busbar is required?
Busbars distribute electricity with greater ease and flexibility than some other more permanent forms of installation and distribution. Sometimes spelled bus bar or buss bar, they are often metallic strips of copper, brass, or aluminum that both ground and conduct electricity.
How many types of busbar are there?
Main and Transfer Bus Arrangement Such type of arrangement uses two type of busbar namely, main busbar and the auxiliary bus bar. The busbar arrangement uses bus coupler which connects the isolating switches and circuit breaker to the busbar.
