Types of Output Devices in Computer
In Computer, Any device that gives the output or result/information that is called Output Device.
An output device is any peripheral device that receives data from a computer, usually for display, projection. An output device works by receiving a signal from the computer and using that signal to perform a task to display the output. There are two types of output devices as shown in Figure:
Soft Copy Output Devices:
Soft copy output devices are those output devices which produce an electronic version of an output.
Example:
1. Monitor
2. Speaker
3. Projector
Some features of a Soft copy output include:
2. The user can easily edit the soft copy output.
3. Soft copy can’t be used by people who don’t have a computer.
4. Searching data in a soft copy is easy and fast.
5. Electronic distribution of a soft copy is cheaper. It can be done easily and quickly.
Monitor:
The most common output device is the Monitor. The monitor visually relays an image, which is created by the computer’s operating system. So, Monitor also is referred to as a VDT (Video Display Terminal) and VDU (Video Display Unit). The computer user sends manipulations through input devices, which enter the motherboard and processor. A monitor is made up of circuitry, a screen, a power supply, buttons to adjust screen settings, and casing that holds all of these components.
Speaker:
A Speaker is an output device that connects to a computer to generate sound. The signal used to produce the sound that comes from a computer speaker is created by the computer’s sound card. Speaker is used to describing the user who is giving vocal commands to a software program.
Projector:
A Projector is an output device that can take images generated by a computer and reproduce them by projection onto a screen, wall, or another surface. In most cases, the surface projected onto is large, flat, and lightly coloured.
Hard Copy Output Devices:
Hard copy output devices are those output devices that produce a physical form of output.
Example:
1. Printer
2. Plotter
Some features of a Hard Copy output include:
2. Editing the hard copy is difficult.
3. Hard copy output can be easily distributed to people who don’t have a computer.
4. Searching data in a hard copy is a tiring and difficult job.
5. Distribution of a hard copy isn’t only costly but also slower.
Printer:
The Printer is an important accessory of any computer system, especially for a graphics system. The printer is used for documentation, print media, or books, etc.
There are mainly five types of printer:
1. Dot Matrix Printer
2. Line Printer
3. Laser Printer
4. Inkjet Printer
5. Electrostatic Printer
Plotter:
A Plotter is a vector device that can directly reach specific positions on printer paper without raster scan device. A plotter is a computer hardware device much like a printer that is used for printing vector graphics. Instead of toner, plotters use a pen, pencil, marker, or another writing tool to draw multiple, continuous lines onto the paper rather than a series of dots like a traditional printer. It is widely used for Computer-Aided Design (CAD).
