Access time is the time delay or latency between a request to an electronic system, and the access being completed or the requested data returned

Clock speed is the speed at which the microprocessor executes instruction.

It is extremely fast memory would store data that is frequently accessed and if possible, the data that is closer to it. This helps to achieve the fast response time.

Electrically Erasable Programmable Read-Only Memory is a special type of PROM that can be erased I by exposing it to an electrical charge

It denotes read and write operation, where 1 (R) denotes read operation and 0 (\(\bar{W}\)) denotes write operation.

The Storage unit of a computer system depends on Access time and storage capacity

The basic storage units are
(i) Primary memory
(ii) Secondary memory

(i) Data bus: Bidirectional
(ii) Address bus: Unidirectional

 A bus is a collection of wires used for communication between the internal components of a computer

(i) MAR (Memory Address Register)
(ii) MDR (Memory Data Register)

Ultra-violet-rays is used to erase the content of a EPROM.

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

The Program Counter (PC) is a special register in the CPU which always keeps the  address of the next instruction to be executed.

A command which is given to a computer to perform an operation on data is called an instruction

A Microprocessor's performance depends on the following characteristics:
(a) Clock speed
(b) Instruction set
(c) Word size
