We always press the power button of laptop or PC without even thinking what is really happening inside the laptop as soon as we press the power button, how does it lead to start the computer? What are the components that help our system to start? etc. So, today in this article we will learn about How does Computer really starts?...
Von Neumann Architecture: Von Neumann Architecture is a digital computer architecture whose design is based on the concept of stored program computers where program data and instruction data are stored in the same memory. This architecture was designed by the famous mathematician and physicist John Von Neumann in 1945....
MRAM stands for magnetoresistive random access memory and is a non-volatile type of RAM....
The full form of SSD is Solid State Drive. SSD does not use Mechanical Components like HDDs. HDDs use Disks to store and retrieve data by revolving very fast at about 5400rpm or 7200rpm, but SSD use chips to store and retrieve data. SSDs are faster than HDDs because the speed of HDD depends upon the rate of revolution of the disks contained inside, whereas SSDs have no such concept of disks....
Prerequisite – Compact Disk (CD)
CD-R stands for Compact Disc – Recordable. It is a digital optical disc storage format which was introduces in 1988. CD-R is such type of compact disc that can be written only once. It can be read many times. It is made of a reflective metal disk with a layer of green or opaque bye on top. It is a blank CD in which data can be stored once and after storing data it is converted into CD-ROM.
CD-R disks can be read by most plain CD readers. It can also be read by CD readers manufactured prior to the introduction of CD-R....
Full form of SMPS is Switch Mode Power Supply. It is one of the crucial parts of a motherboard or a PCB(Printed Circuit Board)...
1. Arithmetic Pipeline :
An arithmetic pipeline divides an arithmetic problem into various sub problems for execution in various pipeline segments. It is used for floating point operations, multiplication and various other computations. The process or flowchart arithmetic pipeline for floating point addition is shown in the diagram....
According to IEEE standard, floating-point number is represented in two ways:...
In computer central processing units, micro-operations (also known as micro-ops) are the functional or atomic, operations of a processor. These are low level instructions used in some designs to implement complex machine instructions. They generally perform operations on data stored in one or more registers. They transfer data between registers or between external buses of the CPU, also performs arithmetic and logical operations on registers. In executing a program, operation of a computer consists of a sequence of instruction cycles, with one machine instruction per cycle. Each instruction cycle is made up of a number of smaller units – Fetch, Indirect, Execute and Interrupt cycles. Each of these cycles involves series of steps, each of which involves the processor registers. These steps are referred as micro-operations. the prefix micro refers to the fact that each of the step is very simple and accomplishes very little. Figure below depicts the concept being discussed here....
Prerequisite – Difference between Micro-controller (µC) and Microprocessor (µP) Micro-controller is a single Integrated Circuit (IC) which is comparable to a little stand alone computer and it is designed to govern a specific operation in an embedded system...
