A computer is made up of simple parts a microprocessor, memory storage, a motherboard that connects the two, a keyboard and a mouse for navigating through programs and files, and a monitor to view information on the computer. (DCP Live the blog) One of the reasons computers are such a powerful tool is because they are so simple, as stated above. Also computer are a great tool to use because of their able to connect to any other computer in the world. Computers allow for mass amounts of information that were previously unable to be seen to be readily available for use anywhere in the world. Before computers one had to go to a library and look in books for information, now the information is available at the touch of a button through the power of computers.
Every day the majority of us interact with computers in one way or another. Be it the computer we use at work or home, the computers in some of the newer cars, or even our cellphones, which are just small computers, we rely on computers for a lot of things. But not many people know how a computer actually works. What’s inside of a computer that makes everything it does possible? Three of the most important pieces of hardware in the computer are the hard drive, the Random Access Memory (RAM), and the Central Processing Unit (CPU).

Today's world relies heavily on computers, and most people know how to use a computer, whether for school, business or leisure. Most people do not understand how it works, and only ask questions when it does not work. The computer has several parts and in order to understand each part, it is easier to compare them to something everyone can understand. There are several books available for those interested in understanding the how and why a computer works. In the book, Is This Thing On, there is a comparison of the central processing unit, or CPU: "The CPU is to information on the computer what the post office is to a letter" (Stokes 15).
