Answer:
A computer is a complex machine. While most of it works on a microscopic level, it certainly has recognizable macroscopic components that contribute to its uses. A computer can be used to do just about anything from simple calculations to preparing reports to sending rockets into space to simulating the spread of cancer in body organs. Some of the parts are, the motherboard, the power supply, the central processing unit, the optical drive ect. The motherboard plays roles like storing some simple information when the computer is off, such as the system time. The power supply, as you might have already guessed is the powerhouse of the computer. The CPU mainly does arithmetic and logical tasks. It will make a bunch of calculations to ensure the functions of the computer are carried out efficiently. An optical drive is used to read CDs and DVDs, which can be used to listen to music or watch movies. They can also be used to install software, play games, or write new information into a disk.
