COMPUTER OUTPUT DEVICES



Task 1. Preparing a PPT presentation on output devices.

What is Output Device?

Definition: Output device is a hardware component that is used for displaying the results of data which are processed by computer system. Output devices allow to convert the electronic information into the humans’ readable format. This format may be audio, visual, textual, or hard copy such as a printed document.
Key difference in between input device and output device is that input device helps to insert data to computer, but output device retrieve data from computer’s storage memory.
These output devices are two kinds that are either wired or wireless.
Types of Output Devices:

Visual Output Devices

When output devices let uses to view the result or output as image or video format on the screen, then these output devices are known as ‘Visual Output Devices’. For examples are video card, projector, monitor and so on.

Data Output Devices

As the name suggests, when user are capable to read and understand. But it can’t get to access otherwise. These types of result are usually produced in textual format. For example – GPS and more

Print Output Devices

These types of output devices let you to produce a printed hard copy of electronic data processed by computer system are known as print output devices. For example are plotter, printer, braille reader, and more.

Sound Output Devices

These kinds of output devices receive the information from the computer in audio formats is known as sound output devices. For examples are sound card, headphones, speakers, etc.
