Computer Science

Output device: An output device is any peripheral that receives data from a computer, usually for display, projection, or physical reproduction. For example, the image shows an inkjet printer, an output device that can make a hard copy of any information shown on your monitor. Another example of an output device is a computer monitor, which displays an image that is received from the computer. Monitors and printers are two of the most common output devices used with a computer. Types of output devices: The following list contains many different output devices.

Input device: In computing , an input device is a peripheral (piece of computer hardware equipment) used to provide data and control signals to an information processing system such as a computer or information appliance . Examples of input devices include keyboards , mouse , scanners , digital cameras and joysticks . Many input devices can be classified according to: modality of input (e.g. mechanical motion, audio, visual, etc.) whether the input is discrete (e.g. pressing of key) or continuous (e.g. a mouse's position, though digitized into a discrete quantity, is fast enough to be considered continuous) the number of degrees of freedom involved (e.g. two-dimensional traditional mice, or three-dimensional navigators designed for CAD applications) Pointing devices , which are input devices used to specify a position in space, can further be classified according to: Whether the input is direct or indirect. With direct input, the input space coincides with ...

Computer Engineering: Computer engineering is a discipline that integrates several fields of electrical engineering and computer science required to develop computer hardware and software . [1] Computer engineers usually have training in electronic engineering (or electrical engineering ), software design , and hardware-software integration instead of only software engineering or electronic engineering. Computer engineers are involved in many hardware and software aspects of computing, from the design of individual microcontrollers , microprocessors , personal computers , and supercomputers , to circuit design . This field of engineering not only focuses on how computer systems themselves work, but also how they integrate into the larger picture. [2] Usual tasks involving computer engineers include writing software and firmware for embedded microcontrollers , designing VLSI chips, designing analog sensors , designing mixed signal circuit boards , and designing opera...

Computer science is the study of the theory, experimentation, and engineering that form the basis for the design and use of computers . It is the scientific and practical approach to computation and its applications and the systematic study of the feasibility, structure, expression, and mechanization of the methodical procedures (or algorithms ) that underlie the acquisition, representation, processing, storage, communication of, and access to information . An alternate, more succinct definition of computer science is the study of automating algorithmic processes that scale. A computer scientist specializes in the theory of computation and the design of computational systems. [1] Its fields can be divided into a variety of theoretical and practical disciplines . Some fields, such as computational complexity theory (which explores the fundamental properties of computational and intractable problems), are highly abstract, while fields such as computer graphics emphasiz...
