What are the 2 main input devices and 2 main output devices?

What are the 2 main input devices and 2 main output devices?

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.

What are two basic input output operations?

There are three basic types of input-output according to the method of controlling and synchronising data transfer: (i) Program-controlled I/O (ü) Interrupt-controlled I/O (iii) Direct-memory-access I/O. the I/O device signalling its readiness to transmit or receive data and the data transfer actually taking place.

What are the 2 categories of input devices?

Input devices are broken down into 3 categories: keyboards, pointing devices, and Data-Entry devices.

What are 2 input and output devices?

Answer: Input Devices: Computer related input devices are Keyboard, Mouse, Touchpad, TrackPoint, Scanner, Microphone, Digital Cameras, Barcode reader, Joystick, Webcam, etc. Output Devices: Few examples of output devices are Printers, Projector, Plotters, Monitor, Speakers, Head Phone, etc .

What are the two output devices?

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

Which are both input and output devices?

For instance, a keyboard or computer mouse is an input device for a computer, while monitors and printers are output devices. Devices for communication between computers, such as modems and network cards, typically perform both input and output operations.

What are the two types of input output addressing methods?

The two most common methods are either ‘memory mapped’ or ‘dedicated port addressed’.

What are the types of input and output devices?

Input/output devices are usually called I/O devices. They are directly connected to an electronic module inside the systems unit called a device controller….Input and Output Devices

• Keyboard.
• Mouse.
• Microphone.
• Bar code reader.
• Graphics tablet.

What are input output devices?

An input device is something you connect to a computer that sends information into the computer. An output device is something you connect to a computer that has information sent to it.

What are the input output device?

I/O devices are the pieces of hardware used by a human (or other system) to communicate with a computer. For instance, a keyboard or computer mouse is an input device for a computer, while monitors and printers are output devices.

What are the different types of input and output devices?

To work with these data, we require different types of devices. These devices can help us enter data into the computer. These devices are called input and output devices. They mainly cover devices like mouse, keyboard, printer, speaker, joystick, etc which can be used with a computer.

What does an I / O device ( input / output device ) mean?

Because most hardware devices do not require an input and output communication with the computer, most IO devices are storage devices. So, when you encounter an I/O error or I/O device error it’s an indication that the operating system cannot read or write to a device. Write protection is enabled.

When do you need to input data into a computer?

Before a computer can process your data, you need some method to input the data into the machine. The device you use will depend on what form this data takes (be it text, sound, artwork, etc.). Similarly, after the computer has processed your data, you often need to produce output of the results.

What kind of input does a keyboard do?

· Keyboard is character-based input device capable of inputting alphanumeric data · Keyboard input is decoded internally in the form of Unicode, ASCII or EBCDIC codes · In multi-user systems many keyboards can be connected to the computer system
