The monitor

A monitor visual display for computers. The display device in modern monitors is typically a thin film display thin panel, while older monitors used a cathode ray tube about as deep as the screen size.
Originally, computer monitors were used for data processing while television screens were used for entertainment. From the 1980s onwards, computers (and their monitors) have been used for both data processing and entertainment, while televisions have implemented some computer functionality.

CPU(Central Processing Unit!)

The CPU is commonly preferred to be known as the brains of a computer. The CPU is responsible for executing a sequence of stored instructions called a program. This program will take inputs from an input device, process the input in some way and output the results to an output device.CPUs aren’t only found in desktop or laptop computers, many electronic devices now rely on them for their operation. Mobile phones, DVD players and washing machines are examples of equipment that have a CPU.
PROGRAM:A list of instructions written in programming language.
Input:Everything that goes into a system.
Output:Anything that comes out of a computer. Output can be meaningful information or gibberish, and it can appear in a variety of forms -- as binary numbers, as characters, as pictures, and as printed pages. Output devices include display screens, loudspeakers, and printers.Output device: Thes are devices such as speakers and printers.DVD:Used to store data.E.G. A movie
