An input device is essentially a piece of hardware component used to provide data and control signals to an information processing system such as computer or information device. Common inputs devices on modern computers include keyboards, mouse and touch screen which are used to enter commands and data directly. Other examples of input devices include scanners, digital cameras, joysticks and microphones. An output device is any hardware component that use received data from a computer to perform a task.

Computer Basics: What Is an Output Device? 10 Examples

Paul's passion for technology and digital media goes back over 30 years. Born in the UK, he now lives in the US. Read on for 10 examples and the definition of an "output device. An output device is a piece of computer hardware that receives data from a computer and then translates that data into another form. That form may be audio, visual, textual, or hard copy such as a printed document. The key distinction between an input device and an output device is that an input device sends data to the computer, whereas an output device receives data from the computer.

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. Some input devices are:. They are directly connected to an electronic module inside the systems unit called a device controller. For example, the speakers of a multimedia computer system are directly connected to a device controller called an audio card such as a Soundblaster , which in turn is connected to the rest of the system. Most modern automobiles are controlled by a computer. Do you think that the computer in your car has:.

Input and Output Devices

Inputs are the signals or data received by the system and outputs are the signals or data sent from it. Every task we have the computer do happens inside the central processing unit CPU and the associated memory. Once our program is loaded into memory and the operating system directs the CPU to start executing our programming statements the computer looks like this:. Historically this was done with punched cards and printouts. Tape drives were used for electronic storage.

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. Most devices are only input devices or output devices, as they can only accept data input from a user or output data generated by a computer. For example, as shown in the top half of the image, a keyboard sends electrical signals, which are received as input. Those signals are then interpreted by the computer and displayed, or output , on the monitor as text or images.

Первое послание, которое он отправил Халохоту, не оставляло места сомнениям, тем более что они это уже обсуждали: убить Энсея Танкадо и захватить пароль. Стратмор никогда не спрашивал у Халохота, как тот творил свои чудеса: тот просто каким-то образом повторял их снова и. Энсей Танкадо мертв, власти убеждены, что это сердечный приступ, прямо как в учебнике, кроме одного обстоятельства.

 Вас подбросить в аэропорт? - предложил лейтенант - Мой Мото Гуччи стоит у подъезда. - Спасибо, не стоит. Я возьму такси.  - Однажды в колледже Беккер прокатился на мотоцикле и чуть не разбился. Он больше не хотел искушать судьбу, кто бы ни сидел за рулем.

 Я же сказала вам, что ревела навзрыд, опоздав на самолет. Он перевел взгляд на слова, нацарапанные на ее руке. Она смутилась.

Молодые люди поднялись по ступенькам, и двигатель автобуса снова взревел. Беккер вдруг понял, что непроизвольно рванулся вперед, перед его глазами маячил только один образ - черная помада на губах, жуткие тени под глазами и эти волосы… заплетенные в три торчащие в разные стороны косички. Красную, белую и синюю. Автобус тронулся, а Беккер бежал за ним в черном облаке окиси углерода.

 Да, - сказал Фонтейн, - и двадцать четыре часа в сутки наши фильтры безопасности их туда не пускают. Так что вы хотите сказать. Джабба заглянул в распечатку. - Вот что я хочу сказать. Червь Танкадо не нацелен на наш банк данных.
