Difference between Semiconductors and Superconductors
An electric conductor is defined as a material that allows the flow of electric current or electric charges across it. In this article, we will discuss the differences between two important types of electric conductors: semiconductors and superconductors. What is a Semiconductor? Semiconductors are defined as a category of electric conductors whose conductivity ranges between that of insulators and conductors. Semiconductors are formed by mixing or doping impurity atoms with pure semiconductor elements. This addition of impurities enhances the conducting capabilities of the semiconductor material. Based on the type of element being doped, semiconductors are categorized into the following two ...
Read MoreDifference between Frequency and Phase Modulations
In communication systems, modulation is a process of changing the characteristics of a data carrier wave so that it can cover the desired distance for data transmission. Modulation is a necessary process in communication systems to increase the reliability of data communication. In the modulation process, an additional signal, called carrier signal, is generated that can go up to long distances, then the message signal is superimposed with this carrier signal, so that the carrier signal transmit the message signal over a long distance without getting affected by the external disturbances. This process is known as modulation. There are ...
Read MoreDifference Between DVD-R and DVD+R
DVD stands for Digital Versatile Disk. DVD is a type of optical storage device used to store digital information. DVD uses red laser to read and write on the disk. DVD is a cheap method of storing and transferring of data in computers. Based on the nature, DVDs come in several formats such as, DVD-ROM DVD-RAM DVD-R DVD+R DVD-RW DVD+RW In this article, we will talk about DVD-R and DVD+R, and the important differences between DVD-R and DVD+R. What is DVD-R? DVD-R stands for Digital Versatile Disk Recordable. DVD-R is pronounced as DVD Dash R. DVD-R is ...
Read MoreDifference between Dual Core and Octa Core Processors
In computers and any other computing device, the processor is the most significant component of the system as it performs the most crucial task, i.e. processing. These days, we have several types of processors such as single core processor, dual core processor, quad processors, hexa core processor, octa core processor, etc. To understand the meaning of “core” in processor, consider the example of a highway with heavy traffic. If the highway have only one-way mode, then all the vehicles should pass one by one in a queue. Therefore, the taken to reach the destination by a vehicle will be more. ...
Read MoreDifference between Desktop and Tablet
Both desktop and tablet are the types of microcomputers as they have the CPU in the form of a microprocessor unit. This article is primarily meant for explaining the important differences between desktop and tablet. The most fundamental difference between desktop and tablet is that the desktop is a type of non-portable microcomputer designed to use regularly at one location, whereas a tablet is a type of portable microcomputer which is designed to carry from one place to another. Basically, a tablet is a smartphone equipped with most features of a microcomputer. Before going to discuss the differences between ...
Read MoreDifference between Desktop and Laptop
We use computers to perform numerous works in offices, home, industries, etc. Several types of computers have been developed for different purposes. The two most common types of computers are desktop and laptop. Both desktop and laptop are the types of microcomputers used in almost every office and home. The fundamental difference between desktop and laptop is that the desktop computer is a type of computer having its peripherals like mouse, keyboard, monitor, speakers, etc. connected together through wires and cables, therefore, desktop computers are non-portable computers. On the other hand, the laptop is a compact form of microcomputer in ...
Read MoreDifference between CD-ROM and Magnetic Disks
CD-ROM and Magnetic disks are the types of permanent (non-volatile) storage media used in computers and many other digital devices to store data and information in digital form. In this article, we will discuss the important differences between CD-ROM and magnetic disks. The most fundamental difference between CD-ROM and magnetic disks is that CD-ROM is a type of optical storage device, whereas magnetic disks, as the name implies, be the type of magnetic storage device. Before discussing the differences between CD-ROM and magnetic disks, let us first know a bit about them individually. What is a CD-ROM? CD-ROM stands for ...
Read MoreASCII vs. UNICODE
ASCII and UNICODE are the two most extensively used character encoding schemes in computer systems. The most basic difference between ASCII and UNICODE is that ASCII is used to represent text in form of symbols, numbers, and character, whereas UNICODE is used to exchange, process, and store text data in any language. What is ASCII? ASCII stands for American Standard Code for Information Interchange. It is a standard developed for character encoding in electronic communication. ASCII was first published in 1963. In computers and other electronic systems, it is used for representing text as symbols, characters, and numbers. In ASCII, ...
Read MoreC-LOOK vs C-SCAN Disk Scheduling Algorithm
In computer systems, disk scheduling is required for smooth operation of the system. Disk scheduling is done by the operating system of the computer, in which it schedules I/O requests arriving on the disk. Therefore, disk scheduling is also called as I/O scheduling. In computer systems, disk scheduling or I/O scheduling is important because there could be multiple I/O requests received from the different processes at the same time, but the disk controller can serve only one request at once, and all other requests have to wait for next schedule. In operating systems, several disk scheduling algorithms used such as ...
Read MoreBooting Process in DOS Operating System
What is Booting? Booting is a process of starting a computer or computer like device such as a smartphone, etc. Therefore, booting of a computing device start when we press the power button of the device, it makes the computer or the device ready for use. Actually, when a computer or any computing device is switched off, its operating system remains in the secondary memory like hard disk of the system. But for execution of a software, it must be in the main memory of the system. Hence, booting may also be defined in other words as, the process of ...
