How Does the Computer Work?
Specific purpose: To inform and educate the audience about how the computer works. Central idea: The types of hardware that all computer systems use and the types of software that make them run. Attention Statement:
Most of American families nowadays have at least one or more computer in their house. Computer has become a very important piece in our life. May be some people don’t realize it but we use computer almost every day. Like millions of computer users, microcomputers we used to play games, explore the Internet, write papers, or create a professional-looking proposal or flyer. However, have you ever wondered? How does the computer perform all these applications exactly like you want it to behind your computer case or monitor screen? I will tell you the types of hardware that all computer systems use and the types of software that makes them run. Transition: Let’s start about the basic things of computer A computer is an electronic machine that processes information—in other words, an information processor: it takes in raw information (or data) at one end, stores it until it's ready to work on it, chews and crunches it for a bit, then spits out the results at the other end. This process is BIOS (basic input and output system). Taking in information is called input, storing information is better known as memory (or storage), chewing information is also known as processing, and spitting out results is called output. (Woodford) Transition: Now let’s move on to the rest of hardware inside the computer In the past computers used vacuum tubes, silicon, or other inefficient items to run. Once nanotechnology came into the game it changed the way computers did just about everything. All the information is stored inside chips. These chips each have their own functions and are embedded with certain tasks to do. From wires they communicate with one another to perform certain tasks or send information from one area to another at a...
