Choose the correct option and mark your choice against the corresponding question number in the given answer sheet by darkening the corresponding circle with a lead pencil. Now they are also used with nonportable desktop computer systems because they occupy less table space.

Input and Output Devices of Computer

Output Device can produce the final product of machine processing into a form usable by humans. It provides man to machine communication. Keyboard is most common input device is used today. The data and instructions are input by typing on the keyboard. The message typed on the keyboard reaches the memory unit of a computer.

In computing , an input device is a piece of equipment used to provide data and control signals to an information processing system such as a computer or information appliance. Examples of input devices include keyboards , mouse , scanners , cameras , joysticks, and microphones. A 'keyboard' is a human interface device which is represented as a layout of buttons. Each button, or key, can be used to either input a linguistic character to a computer, or to call upon a particular function of the computer. It acts as the main text entry interface for most users.

Input and Output Devices Question and Answers | Basic Computer Knowledge

A peripheral device is generally defined as any auxiliary device such as a computer mouse or keyboard, that connects to and works with the computer in some way. RAM—random access memory—straddles the line between peripheral and primary component; it is technically a storage peripheral, but is required for every major function of a modern computer and removing the RAM will effectively disable any modern machine. Many new devices such as digital watches, smartphones and tablet computers have interfaces which allow them to be used as a peripheral by a full computer, though they are not host-dependent as other peripheral devices are. According to the most technical definition, the only pieces of a computer not considered to be peripherals are the central processing unit, power supply, motherboard, and computer case. Usually, the word peripheral is used to refer to a device external to the computer case, like a scanner, but the devices located inside the computer case are also technically peripherals. In a system on a chip, peripherals are incorporated into the same integrated circuit as the central processing unit.

The Input Devices are the hardware that is used to transfer transfers input to the computer. The data can be in the form of text, graphics, sound, and text. Output device display data from the memory of the computer. Output can be text, numeric data, line, polygon, and other objects. The most commonly used input device is a keyboard. The data is entered by pressing the set of keys.

Chapter 9: Input-Output Devices

The transfer of data from a CPU to peripheral devices of computer is achieved through. Which key is used in combination with another key to perform a specific task? Students can learn and improve on their skillset for using Input and Output Devices Question and Answers Basic Computer Knowledge effectively and can also prepare for competitive examinations like They are explained in elaborated manner to get clear subject knowledge.

Such devices make up the peripheral equipment of modern digital computer systems. Peripherals are commonly divided into three kinds: input devices, output devices, and storage devices which partake of the characteristics of the first two. An input device converts incoming data and instructions into a pattern of electrical signals in binary code that are comprehensible to a digital computer. An output device reverses the process, translating the digitized signals into a form intelligible to the user.

Input device

Гул становился все громче. И вдруг впереди словно зажглась заря. Темнота стала рассеиваться, сменяясь туманными сумерками.

 Я сказала.  - Она смотрела ему прямо в. Хейл наклонил голову набок, явно заинтригованный такой скрытностью. И, как бы желая обратить все в игру, сделал еще один шаг. Но он не был готов к тому, что произошло в следующее мгновение.



Hardware refers to the physical, tangible computer equipment and devices, which provide support for major functions such as input, processing internal storage, computation and control , output, secondary storage for data and programs , and communication.
