Difference between Hard Disk and Floppy Disk
In computers, different types of disks are used to store data and information. The two most popular types of disks are hard disk and floppy disk. Both hard disk and floppy disk are the type of secondary storage devices used to store permanent data and information. The primary difference between hard disk and floppy disk is that the hard disk is made of aluminum, while the floppy disk is made up of plastic. In this article, we will discuss the important differences between hard disk and floppy disk. But before that let us first discuss the basics of hard ...
Read MoreDifference between CVT and UPS
There are two different technologies namely, CVT (Constant Voltage Transformer) and UPS (Uninterrupted Power Supply) that are used for providing power conditioning and protection. A CVT is an electrical device used to provide a constant output voltage despite variations in the input voltage or load, whereas a UPS is an electronic device used to provide power during power outages and voltage fluctuations. Read this article to learn more about CVT and UPS and how they are different from each other. What is a CVT? A CVT is an electrical device that is used to provide a constant and stable ...
Read MoreDifference between Computer and Embedded System
A computer is a general purpose electronic device that is used to perform a wide range of computing tasks, whereas an embedded system is a specialized computer that is used to perform one or more specific functions. Read this article to learn how a computer is different from an embedded system. What is a Computer? A computer is an electronic machine that is designed to accomplish a wide range of computing tasks. Hence, a computer is basically a versatile electronic device that can be utilized for a variety of applications from general word processing and web browsing to complex ...
Read MoreDifference between CD-R and CD-RW
Both CD-R and CD-RW are types of optical storage devices. A CD-R (Compact Disk- Recordable) is a write-once read-many device, which means data can be written to it only once but can be read many times. In contrast, a CD-RW (Compact Disk-Rewritable) is a CD that allows data to be written multiple times. Read this article to learn more about CD-R and CD-RW and how they are different from each other. What is CD-R? CD-R stands for Compact Disk-Recordable. CD-R is a type of optical storage disk that is used for storage of digital data. It is a type ...
Read MoreDifference between AT and ATX Power Supply
In a computer system, power supply or power supply unit is a hardware component that supplies required electrical power to other components of the computer system. The power supply unit converts a 220 V AC (Alternating Current) supply into a low voltage DC (Direct Current) supply. The major function that a computer power supply unit performs are − Rectification − Conversion of alternating current supply into direct current supply. Voltage transformation − Decreases the high AC voltage into low voltages. Voltage regulation − Regulates the output voltage to make it constant even when the input voltage is fluctuating. ...
Read MoreDifference between AT and ATX Motherboard
In a computer system, motherboard is a crucial part of the system. This is because, the complete electronic circuit of the computer system is designed on it. Motherboard includes several electronic circuits and slots for connecting various system components like RAM, HDD, CPU, etc. At present, there are several types of motherboards available in market. In this article, we will discuss the two important types of motherboards namely, AT motherboard and ATX motherboard, and the important differences between them. So, let us start with a basic introduction of AT and ATX motherboard. What is AT Motherboard? AT Motherboard stands ...
Read MoreBrushless DC Motors
An electric motor is an energy conversion device that converts electrical energy into mechanical energy. Therefore, the input to an electric motor is electricity, while the output of the electric motor is mechanical energy in the form of rotation of the shaft. Based on the type of electrical energy that motor requires to operate, the electric motors are classified into two types, i.e. AC Motor and DC Motor. An AC Motor or alternating current motor is one that transforms electrical energy in the form of alternating current into rotational mechanical energy. On the other hand, an electric motor which transforms ...
Read MoreBenefits of Hosted Desktop
What is a Hosted Desktop? A type of cloud computing service model that allows users to access a desktop environment virtually from anywhere with the help of an internet connection is referred to as a hosted desktop. The hosted desktop is also known as virtual desktop because the users can access the virtual desktop environment from any device like tablet or smartphone without having a physical computer. Hosted desktop is a termed as Desktop as a Service (DaaS). In the hosted desktop model, a desktop environment is hosted on servers in a data center and it can be then ...
Read MoreBakery Algorithm in Process Synchronization
It is a prerequisite to understand the terms "process synchronization", "critical section", and "inter-process communication" before we proceed to discuss the Bakery Algorithm in Process Synchronization. What is Process Synchronization? In a multiprocessing system, the process synchronization is a method of coordinating execution of multiple processes so it is ensured that all the processes access shared resources in a controlled and predictable manner. The primary goal of process synchronization is to avoid the problem of race conditions in the system. Though, it also resolves many other issues related to synchronization in a concurrent system. Therefore, the process synchronization ensures that ...
Read MoreBad Block in Operating System
In operating systems, a bad block is a sector on a dick drive or a flash of the computer system which is not usable due to a permanent damage to the disk like physical damage of the disk surface or failed transistors of flash memory. In this article, we will discuss the bad block in detail along with their different types, causes, replacement, etc. So let’s get started with the basic definition of bad block in operating system. What is a Bad Block in Operating System? The storage area of a memory device such as disk drive or flash drive ...
