dont have to be in order, around 200 words or less will be fineThe hardware is the tangible (metal and plastic) stuff you buy. It provides a place to store process and retrieve information, provides power to the screen and other input and output devices, and is the “place” that software runs.The software is what will interest us most in this course. It is the instructions or logic that tells the computer what to do.The networks allow communication between individual computers. This communication allows us to talk to each other, but it also allows a set of computers to work together to create programs that are much larger and faster than one computer alone could create.The data is the “bits” of information that are stored inside the computer. Video, numbers, text and images are all examples. In the end, computers are simply a means to collect, store, process and give us back the right bits of data. As we will see later, I will use the term Information to talk about a particular kind of data.The equations are strung together sequentially by computer code. The code is also called logic to reflect the fact that it is the reasoning the computer uses to complete its tasks.The numbers are called data. They can be different each time the computer code is run, so they can’t be stored inside the code. As we will see later in the course, the numbers are generally stored in a database.An application is a program or set of programs that work as a unit to allow you to do something on a computer.In computers, a network is the way computers talk togetherThe servers are the software that delivers information; they “serve” information from one computer to another through the Internet.Most computers run browsers, which are programs that receive and display information for the user. To do this, they send requests to Web servers.The Web is the world’s library. It is the place where all (or at least the most) of the world’s information resides.
