Computers have come a long way since their invention in the early 1800s. They are now an integral part of our lives, used in a variety of ways to make our lives easier. We use them for work, play, communication, and more. But what exactly does a computer do?
Simply put, a computer is a device that performs calculations and processes information. It can be used to store, retrieve, and edit data. Computers can also be used to generate visuals and sounds. They are able to do all of this because they are made up of different parts that work together.
The most important part of a computer is the central processing unit, or CPU. This is the part of the computer that performs the calculations and processes the information. The CPU is helped by the random access memory, or RAM. This is where the data that is being processed is stored. The computer also has a hard drive, which is where the data is permanently stored.
The computer also has a number of input and output devices. The input devices are the devices that allow you to input information into the computer. The most common input device is the keyboard. Other input devices include the mouse, the trackball, the touchpad, and the joystick. The output devices are the devices that allow you to see and hear the results of the calculations that the computer has performed. The most common output device is the monitor. Other output devices include the printer, the speaker, and the microphone.
So, that is what a computer does. It performs calculations and processes information. It can store, retrieve, and edit data. It can also generate visuals and sounds. It does all of this with the help of its input and output devices.

What are the 5 main functions of a computer?
A computer is a device that can be programmed to carry out a sequence of arithmetic or logical operations. The five main functions of a computer are input, processing, output, storage, and communication.
Input is the process of getting data into the computer. This can be done through the use of a keyboard, mouse, scanner, or other input device.
Processing is the process of manipulating the data that has been input into the computer. This can be done through the use of software programs that run on the computer.
Output is the process of getting the results of the processing done by the computer out to the user. This can be done through the use of a monitor, printer, or other output device.
Storage is the process of storing data on the computer. This can be done through the use of a hard drive, floppy disk, CD-ROM, or other storage device.
Communication is the process of sending and receiving data between computers. This can be done through the use of a network or the Internet.
