INPUT DEVICE

MEANING :- Input devices are peripherals you can attach to your computer that allow it to receive input from a user. Most computers come standard with two universal input devices: the keyboard and the mouse. Other input devices include game controllers, such as joysticks and game pads, web cams and microphones, scanners and digital cameras. Computers rely on data from input devices; without input devices, a computer cannot receive any information from the user and cannot be operated.

FUNCTION :- Input devices refer to devices such as mice, keyboards, webcams and the microphone. Their main function is to allow the user to control the machine through data input. They are also a medium through which the user communicates with the computer.

EXAMPLES OF INPUT DEVICE It can be used for shortcuts, like copy,

paste, empty trash, etc. It is also used for answering this question. It has many

uses such as type writing ...not just typing but typing with fast speed that consume a lot of time. keyboard also very helpful in Dos command which is

one of the best security system where a mouse can't work.

In computing, a mouse is a pointing device that functions by detecting two-dimensional motion relative to its supporting surface. Physically, a mouse consists of an object held under one of the user's hands, with one or more buttons.The mouse sometimes features other elements, such as "wheels", which allow the user to perform various system-dependent operations, or extra buttons or features that can add more control or dimensional input. The mouse's motion typically translates into the motion of a pointer on a display, which allows for fine control of a graphical user interface.

OUTPUT DEVICE

MENING OF OUTPUT DEVICE:-An output device is any device used to send data from a computer to another device or user. Most computer data output that is meant for humans is in the form of audio or video. Thus, most output devices used by humans are in these categories. Examples include monitors, projectors, speakers, headphones and printers.

FUNCTION OUTPUT DEVICE:-Out put devices refers to those peripherals which gives you the result of a processed input. It can be images on a screen, vibration from a joy pad, print out.

Headphones are a pair of small loudspeakers that are designed to be held in place close to a user's ears. Headphones either have wires for connection to a signal source such as an audio amplifier, radio, CD player, portable media player or mobile phone, or have a wireless receiver, which is used to pick up signal without using a cable. They are sometimes known as ear speakers or, colloquially, cans.[2] The alternate in-ear versions are known as earphones or ear buds. In the context of telecommunication, a headset is a combination of headphone and microphone

Radio is the wireless transmission of signals through free space by electromagnetic radiation of a frequency significantly below that of visible light, in the radio frequency range, from about 30 kHz to 300 GHz.[1] These waves are called radio waves. Electromagnetic radiation travels by means of oscillating electromagnetic fields that pass through the air and the vacuum of space.Information, such as sound, is carried by systematically changing (modulating) some property of the radiated waves, such as their amplitude, frequency, phase, or pulse width. When radio waves strike an electrical conductor, the oscillating fields induce an alternating current in the conductor. The information in the waves can be extracted and transformed back into its original form.

STORAGE DEVICE

A storage device is a device for storing something. The something may be energy, water, data, etcEnergy storage devices: battery, gasholder, petrol tank.Water storage device: water tankData storage device: CD, DVD, hard drive, RAM and ROM chips, magnetic tape, floppy disks

FUNCTION OF STORAGE DEVICE:-Storage devices save all of your computer's permanent information. Things that you download, your preferences and settings, programs and games that you have installed, your operating system, etc. are all installed on your hard drive. When your computer needs to load something, it searches through your HDD to locate the files that it needs. Without storage devices, your computer would not function and would be unable to go beyond the BIOS screen when booting.

CD-ROM drives are very popular for playing and installing media. CD-ROM drives are classified as 5.25-inch drives because they fit into the 5.25-inch drive bays that are used in computer cases. CD-ROM drives come in many forms, including external, internal, and more.

DVD stands for Digital Versatile (or Video) Disc. It is used for storing information in digital form
