Input Devices:

• Input devices are the component of the computer system that accepts incoming data and instructions.
• It converts them into a pattern of electrical signals in binary code that is understandable to a digital computer.

Output Devices:

• Output devices are the component of a computer system that converts the digitized signals into a form understandable to the user.
• The output devices are generally known as the reverse of input devices.
• Output devices also send data from one computer system to another.

Key Points

•  A Visual Display Unit (VDU) is also referred to as a Monitor and VDU (video display unit), a monitor is an output device that displays video images and text.
• A printer is an external hardware output device that takes the electronic data stored on a computer or other device and generates a hard copy.
• A floppy disk is a type of disk storage composed of a disk of thin and flexible magnetic storage medium, sealed in a rectangular plastic enclosure lined with fabric that removes dust particles. It can be both an input and output device.​

Important Points

The Central Processing Unit (CPU):

• The CPU is the brain of the computer.
• Sometimes referred to simply as the processor or central processor, the CPU is where most calculations take place.
• The CPU executes the programs and controls the operation of all the hardware.
• A central processing unit (CPU), also called a central processor, main processor, or just processor is the electronic circuitry that executes instructions comprising a computer program.
• The CPU performs basic arithmetic, logic, controlling, and input/output (I/O) operations specified by the instructions in the program.

​Thus, CPU is not a computer output device.

Mistake Points

• The question is "Which one is not a computer output device?"
• Floppy is both input and output.
• CPU is the only option that is not an output device.
