 What are input devices?

In computing, an input device is a piece of equipment that is used to provide data and control signals to an information processing system, such as a computer or information device. Examples of input devices include keyboards, mouse, scanners, cameras, joysticks, and microphones.
                                 OR
An input device is a term for a physical piece of hardware that connects to a basic device, such as a computer, to provide input to the user. Input devices are generally a class of peripheral devices connected to the primary device. Top examples include: Keyboards.

What is keyboard?

A computer keyboard is an input device modeled after a typewriter keyboard that uses a set of buttons or keys to act as mechanical levers or electronic switches.
There are two layouts of keyboard available QWERTY or non QWERTY.

What is mouse?

Mouse is also an Input device.A mouse is a small, mobile device that lets you control a lot of things on a computer. Most types of mice have two buttons, and some have a wheel between the buttons. Most types of mice are connected to a computer by a cable, and use the power of the computer to operate. Some types of mouse are wireless.

What is scanner?

A scanner, also called an optical scanner, is a computer input device that uses a light beam to scan codes, text, or graphic images directly into a computer or computer system.A scanner is an input device that scans documents such as images and text pages. When a document is scanned, it is converted to digital format. It creates an electronic version of the document that can be viewed and edited on a computer.

What is joystick?

In computers, Joyce Stick is a cursor control device used in computer games and assistive technology. The Joyce Stick, named after the control stick used by pilots to control aircraft's elevators and elevators, is a hand-held lever that is centered at one end and transmits its points to the computer. 

What is microphone?

An example is a microphone transducer, a device that converts information from one form to another. Voice information is available as air pressure samples. The microphone converts this information into electrical current patterns.

What are output devices?

An output device is any piece of computer hardware device that converts information into a human comprehensible form or, historically, a readable physical machine for use with other non-computerized devices. Examples include monitors, printers, speakers, headphones, projectors, GPS devices, optical mark readers, and braille readers. be text, graphics, touch, audio, or video.

What is monitor?

The monitor is an electronic visual computer display that includes the screen, the circuit and the case to which the circuit is attached. Older computer monitors used cathode ray tubes (CRT), which made them bigger, heavier and more inefficient.

What is printer?

A printer is a device that accepts text and graphic output from a computer and transfers information to paper, usually a standard size, 8.5 "by 11" sheet of paper. Printers vary in size, speed, sophistication and price.

What is projector?

A projector or image projector is an optical device that presents an image (or moving images) on a surface, usually a projection screen. Most projectors produce images by flashing light through a small transparent lens, but some newer types of projectors can project the image directly using a laser.

Language translators

 What is language translator? Any program written in high level language is known as source code. However, computers cannot understand the source code. Before running it, the source code must first be translated into a form that the computer understands. Translator is a program that converts source code into machine code. There are generally three types of translators:  compilers Interpretor Assembler What is compilers? The compiler takes the source code as a whole and translates it into machine code at once. Once converted, the object code can be run at any time without assistance. This process is called compilation. Compilers have several advantages: Compiled programs run faster, because they have been translated. A compiled program can be provided as an executable file. An executable file is a file that is ready to be executed. Because an executable file cannot be easily edited, programmers prefer to provide an executable rather than a source code.Developers improve the cod...

What is RAM and ROM?

   What is RAM? RAM stands for Random Access Memory. Practically all computers now Or they rely on memory to perform all their functions. It becomes without RAM. It is impossible to go far after the PC is turned on. Software Applications installed on a computer are largely dependent on RAM. it is Responsible for keeping data while any application is running. Once The application is closed without saving, data is lost.RAM is short for "Random Access Memory" and although it may seem mysterious, RAM is one of the most basic elements of computing. RAM is the fastest and temporary data storage space that a computer needs to access right now or in the next few moments. The difference between Ram and Sam RAM is considered "random access" because it can access any memory cell. This is done directly if the intersection of rows and columns is well known. On the contrary RAM is Serial Access Memory (SAM). SAM stores data as a series of memory cells. Which can only be accessed ...

what is printer and its types?

 What is printer? "A printer is an external output device that takes data from a computer and generates output in the form of graphics / text on a paper".   There are two types of printers.  Impact printer Non-impect printer  What is Impect printer? An impact printer makes contact with the paper. It usually forms the print image by pressing an inked ribbon against the paper using a hammer or pins. Following are some examples of impect printer.  Dot-Matrix Printers: The dot-matrix printer uses print heads containing from 9 to 24 pins. These pins produce The dot-matrix printer uses print heads containing from 9 to 24 pins. These pins produce produces more dots that a 9 pin dot-matrix printer, which results in much better quality and clearer characters. The general rule is: the more pins, the clearer the letters on the paper. The pins strike the ribbon individually as the print mechanism moves across the entire print line in both directions, i-e, from lef...
