Introduction Micro Operation is the functionality of ALU & the control unit of CPU that describes how an instruction is executed. It is the key concept of instruction execution. A digital system performs a sequence of micro-operations on data stored in registers or memory. Definition A micro-operation is an elementary Read more…
Introduction The instruction cycle is the basic operational process of a computer system. It is the process by which a computer retrieves a program instruction from its memory, determines what actions the instruction describes, and then carries out those actions. This cycle is repeated continuously by a computer’s central processing Read more…
Introduction On the occurrence of an interrupt, an interrupt request (in the form of a signal) is issued to the CPU. The CPU on receipt of interrupt request suspends the operation of the currently executing program, saves the context of the currently executing program and starts executing the program which Read more…
History The term RAID was coined by researchers David Patterson, Garth A. Gibson, and Randy Katz at the University of California, Berkeley in 1987. Introduction RAID stands for ‘Redundant Array of Inexpensive Disks’. Now, it is ‘Redundant Array of Independent Disks’ that signify the performance and reliability gains. Definition RAID is an advanced, specific, physical Read more…
Introduction Sequential circuits are digital circuits that have a state or memory, which allows to store information and perform operations based on that stored information. Terminology Clock-Pulse/Clock Signal A clock pulse is a periodic digital signal that is used to synchronize the timing of operations of digital circuits, particularly in Read more…
Introduction It is one of the basic and important types of Logic Circuits. Definition Combinational circuits are digital logic circuits that produce output based solely on the current input values, without any consideration of previous inputs or internal memory. Features These circuits are composed of logic gates and perform specific Read more…
Introduction The logic circuit is a combination of logic gates together as an integrated circuit, to perform some incredibly complex calculations. Definition A logic circuit is a type of electronic circuit, that consists of one or more logic gates in a certain specific sequence, used/found in electronic devices to perform Read more…
Definition Logic gates are fundamental building blocks of digital circuits that perform logical operations on binary inputs to produce a binary output. Features Logic gates are the core components of electronic devices or circuits that implement Boolean functions, which are mathematical functions that operate on binary variables (0 and 1). Read more…
Definition Error detection and correction methods are techniques used to identify and correct errors that may occur during data transmission or storage. Characteristics The errors can result from various factors, such as noise, interference, or hardware issues during transmission. Error detection and correction methods are techniques used in various fields, Read more…
Alphanumeric Representation Definition It is a set of characters containing alphabets (A-Z, a-z), the decimal digits (0-9) and special characters/symbols (roughly 10-15 in numbers) consist of at least 80-100 elements. Alphanumeric Characters are represented in computer in following form – ASCII Representation It is one of the International standard code Read more…
