How do computers use input and output to give and get information?

Question of the Day: How do computers use input and output to get and give the information that they need to solve problems?

1. Typing on a Keyboard (Input) Makes Letters Appear on a Screen (Output)
2. Moving a Mouse or Touch Screen (Input) Changes What Appears on the Screen (Output)

Can a device you use with your computer be both input and output?

Devices for communication between computers, such as modems and network cards, typically perform both input and output operations.

What are the output and input devices of computer?

Keyboard and mouse are the most commonly used input devices. Microphone gives sound or voice input to the computer. Output devices are used to display the result or information on the computer. Monitor and the printer are the commonly used output devices.

Why all input and output devices must be connected to the system unit?

Input and output devices allow the computer system to interact with the outside world by moving data into and out of the system. An input device is used to bring data into the system.

How does data becomes an information in input output process?

DATA PROCESSING CYCLE. Data procesing refers to the transformating raw data into meaningful output. Data Input- the collected data is converted into machine-readable form by an input device, and send into the machine. Output is the production of the required information, which may be input in future.

What is the role of input and output devices in a computer system class 9?

The functioning of a computer system is based on the combined usage of both input and output devices. Using an input device we can give instructions to the computer to perform an action and the device reverts to our action through an output device.

Which of the following is used for input and output both?

The correct answer is Memory. Input devices are used to enter data or instructions into a computer. e.g. Keyboard, Mouse, Digital camera, Scanner, Microphone, etc. The output device receives the information from the processing unit and provides the result in a human-readable form.

What are computer output devices?

An output device is any piece of computer hardware equipment which converts information into a human-readable form. Some of the output devices are Visual Display Units (VDU) i.e. a Monitor, Printer graphic Output devices, Plotters, Speakers etc.

What is the role of an input device and an output device?

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.

How does a computer take input to the user?

Input: Getting Data from the User to the Computer. Some input data can go directly to the computer for processing. Input in this category includes bar codes, speech that enters the computer through a microphone, and data entered by means of a device that converts motions to on-screen action.

What is the input and output of a computer?

But users are very much aware of the input and output associated with the computer. They submit input data to the computer to get processed information, the output. Sometimes the output is an instant reaction to the input. Consider these examples:

What is the first interaction a user has with a computer?

A user’s first interaction with a computer screen may be the screen response to the user’s input. When data is entered, it appears on the screen. Furthermore, the computer response to that data-the output-also appears on the screen. Computer screens come in many varieties, but the most common kind is the cathode ray tube (CRT).

How do factory workers input and output data?

Factory workers input data by punching in on a time clock as they go from task to task. The time clock is connected to a computer. The outputs are their weekly paychecks and reports for management that summarize hours per project on a quarterly basis. A college student writes checks.

What is the meaning of output device?

output device. any hardware component that conveys information from a computer or mobile device to one or more people. printer. an output device that produces text and graphics on a physical medium such as paper.
