A file containing a virus is called infected file. wearable computer: A wearable computer is an electronic device capable of storing and processing data that is incorporated into a person's clothing or personal accessories. A computer network is a group of computers that use a set of common communication protocols over digital interconnections for the purpose of sharing resources located on or provided by the network nodes.The interconnections between nodes are formed from a broad spectrum of telecommunication network technologies, based on physically wired, optical, and wireless radio-frequency methods that … (The term hardware describes the physical aspects of computers and related devices.) Information and translations of computer applications in the most comprehensive dictionary definitions resource on the web. a brief computer history The computer as we know it today had its beginning with a 19th century English mathematics professor name Charles Babbage. There are various types of computer security which is widely used to protect the valuable information of an organization. Volatile vs. non-volatile memory. A desktop computer is a personal computing device designed to fit on top of a typical office desk. Computer hardware is a collective term used to describe any of the physical components of an analog or digital computer. These information system processing steps are:- Input --> Processing --> Output . It may be a tower (also known as a system unit ) or an all-in-one machine, such as an iMac. In contrast, a computer’s hard disk or SDD is its long-term memory, where things are stored more or less permanently. They are designed to be more portable than traditional desktop computers, with many of the same abilities. The computing Performance of a "supercomputer" is measured very high as compared to a general purpose computer. Its principal characteristics are: It responds to a specific set of instructions in a well-defined manner. The computing Performance of a supercomputer is measured in FLOPS (that is floating-point operations per second) instead of MIPS. Description: It fits the description of a computer virus in many ways. In Windows, the desktop includes a task bar, which is located at the bottom of the screen by default. Definition of computer applications in the Definitions.net dictionary. Memory can be either volatile and non-volatile memory. Shortcut definition is - a route more direct than the one ordinarily taken. Definition: A supercomputer is the fastest computer in the world that can process a significant amount of data very quickly. “A short circuit is a connection between two parts of an electrical circuit that you don’t want to be there,” says Karl Berggren, professor of electrical engineering in the Department of Electrical Engineering and Computer Science. A computer's memory is where short-term data is stored so it can be recalled quickly. Meaning of computer applications. Laptops are able to be folded flat for transportation and have a built-in keyboard and touchpad. It includes the desktop background (or wallpaper) and icons of files and folders you may have saved to the desktop. It is the process of preventing and detecting unauthorized use of your computer system. Input refers to the collecting and gathering of data. handtop (ultra personal computer): A handtop is a full-featured portable computer that is slightly larger than a PDA, but much smaller than a laptop. A laptop computer is a small personal computer. If this file is copied to a computer, virus is also copied to the computer. An embedded computer is a computer that is integrated into other devices and is dedicated to the functions of that device. Computer hardware is the collection of physical parts of a computer system. He also heads the Quantum Nanostructures and Nanofabrication Group in the Research Laboratory for Electronics. Computer definition stems from the three steps it gets through to compute a given data. ... A printer is a device that accepts text and graphic output from a computer and transfers the information to paper, usually to standard size sheets of paper. This includes the computer case, monitor, keyboard, and mouse. computer definition. ... Watch a short film about the (ancient) history of printing: He designed the Analytical Engine and it was this design that the basic framework of the computers of today are based on. You may already know that you can use a computer to type documents , send email , play games , and browse the Web . Monitors are similar to TVs but usually display information at a much higher resolution . Definition of Computer Virus “A computer virus is a program that may disturb the normal working of a computer system”. It can execute a prerecorded list of instructions (a program). A microcomputer is a complete computer on a small scale, designed for use by one person at a time. Virus attaches itself to files stored on floppy disks, USBs, email attachments and hard disks. The storage, on the other hand, is home to long-term data like the operating system, applications, and files that need to be kept indefinitely. A human computer, with microscope and calculator, 1952. According to the Oxford English Dictionary, the first known use of the word "computer" was in 1613 in a book called The Yong Mans Gleanings by English writer Richard Braithwait: "I haue [sic] read the truest computer of Times, and the best Arithmetician that euer [sic] breathed, and he reduceth thy dayes into a short number." What does computer memory look like? Software is a general term for the various kinds of program s used to operate computer s and related devices.

Computer memory typically comes in the form of random access memory (RAM) or dynamic random access memory (DRAM). There are two generally, similar and accepted meanings of the phrase personal computer (PC):. A monitor is a piece of computer hardware that displays the video and graphics information generated by a connected computer through the computer's video card. This memory module connects to the memory slot on a computer motherboard. Computer definition is - one that computes; specifically : a programmable usually electronic device that can store, retrieve, and process data.
