Introduction In computer architecture, a processor register is a very fast computer memory used to speed up the execution of computer programs by providing quick access to commonly used values. A register is a word of internal/CPU memory like the accumulator. Most early machines used stack or accumulator type of architectures to manipulate data but these days all CPUs made are of Read more…
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. Micro-operations form the basis of executing 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 Interrupts are crucial for managing asynchronous events and ensuring efficient CPU utilization. Understanding the different types of interrupts and their handling mechanisms is fundamental for system programming, operating system design, and hardware interfacing. Definition An interrupt is an exceptional event that causes the CPU to temporarily transfer its processing 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…
