Data bus is bi-directional because same bus is used for data transmission from microprocessor to memory location of I/O device and vice versa.

Data Transfer means moving data from one component to another

USB 3.0 is the third major-version of the Universal Serial Bus (USB) standard to connect computers with other electronic gadgets. USB 3.0 can transfer data up to 5 Giga byte/second.

Address Bus is used to point the memory location.

Basic set of machine level instructions that a microprocessor is designed to execute is called as an instruction set.

(i) Address Bus

Ultra violet rays are used to erase the contents of EPROM. EPROM retains its contents until it is exposed to ultraviolet light. The ultraviolet light clears its contents making it possible to reprogram the memory.

HDMI (High Definition Multimedia Interface) is an audio/video interface which transfer the uncompressed video and audio data from a video controller, to a compatible computer monitor, LCD projector, digital television, etc.

A program counter (PC) is a CPU register in the computer processor which has the address of the next instruction to be executed from memory. It is a digital counter needed for faster execution of tasks as well as for tracking the current execution point.

Instruction is a command which is given to the computer to perform an operation on a piece of data.

It depends on
(a) Clock speed
(b) Instruction set
(c) Word size
