Quick Answer: What Are The Major Functions Of Output Devices?

What Are the Functions of Output Devices on a Computer?

Input devices are the hardware that give computers instructions.

Output devices relay the response from the computer in the form of a visual response (monitor), sound (speakers) or media devices (CD or DVD drives).

What are the output devices and their functions?

In brief, output unit is responsible for providing the output in user readable form. It can be text, graphics, tactile, audio, and video. Some of the Output devices are Visual Display Units (VDU) i.e. a Monitor, Printer, Graphic Output devices, Plotters, Speakers etc.

What are the main functions of input and output devices?

An input device sends information to a computer system for processing, and an output device reproduces or displays the results of that processing. Input devices only allow for input of data to a computer and output devices only receive the output of data from another device.

What are the 5 output devices?

Computer Basics: 10 Examples of Output Devices

  • 10 Examples of Output Devices. Monitor.
  • Monitor. The most common output device used with computers is the monitor, which displays video images and text.
  • Printer. Printers are another common output device found in homes in offices.
  • Computer Speakers.
  • Headphones.
  • Projector.
  • GPS.
  • Sound Card.

What is output function?

An output function is a function that an optimization function calls at each iteration of its algorithm. Typically, you use an output function to generate graphical output, record the history of the data the algorithm generates, or halt the algorithm based on the data at the current iteration.

Why do we use output devices?

Output devices provide data in different forms like audio, visual and hard copy. It is usually used for display, projection or physical reproduction. Monitors and printers are two of the most familiar output devices used with a computer.

What are types of output devices?

A computer output device is used to extract information from a computer. There are visual, audio, print and data output devices. Different types of specific hardware include monitors, speakers and headphones, printers and external hard drives.

What are the functions of an input device?

The function of an input device is to communicate information to a computer or other sort of information processing equipment. Input devices are types of peripheral devices that communicate with processing units. The most common forms of input device for personal computers are keyboards and mice.

What are the 5 types of monitor?

Types of computer monitors

  • CRT (cathode ray tube) monitors. These monitors employ CRT technology, which was used most commonly in the manufacturing of television screens.
  • LCD (liquid crystal display) monitors. The LCD monitor incorporates one of the most advanced technologies available today.
  • LED (light-emitting diodes) monitors.

What is output devices with examples?

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.

Monitors and printers are two of the most common output devices used with a computer.

Is CPU input or output?

Central processing unit

The CPU is also known as the processor or microprocessor. The CPU is responsible for executing a sequence of stored instructions called a program . This program will take inputs from an input device, process the input in some way and output the results to an output device .

What are the types of function?

The eight types are linear, power, quadratic, polynomial, rational, exponential, logarithmic, and sinusoidal.

How do you determine a function?

It is relatively easy to determine whether an equation is a function by solving for y. When you are given an equation and a specific value for x, there should only be one corresponding y-value for that x-value. For example, y = x + 1 is a function because y will always be one greater than x.

What is a function example?

Typical examples are functions from integers to integers or from the real numbers to real numbers. If the function is called f, this relation is denoted y = f (x) (read f of x), the element x is the argument or input of the function, and y is the value of the function, the output, or the image of x by f.
