Week One: Computer Concepts Describe all the parts of an information system. The information system is made up of five parts. First there are the people which are the most important part. Then there are procedures. Procedures are the guidelines for people to follow when using software, hardware, and data. Next there is the software, also known as programs. The software consists of step-by-step instructions that tell the computer how to work. Next is the hardware. The hardware is the equipment that processes the data to create information. Some examples of computer hardware are keyboard, mouse, and a monitor. Last there is the data. Data is unprocessed facts; this could be text, numbers, images, or sounds. What is an operating system? Give two examples. An operating system is the most important part of your computer. The job of the operating system is to handle all of the technical details such as managing the computer resources, providing an interface between the computer and the user, and to run applications. Two of the most known examples of an operating system are Windows XP and Mac OS X. List three common output devices. Monitors are the most used output devices. Monitors present visual images of text and graphics. They come in all different sizes. Printers are also common in everyday life. Printers translate information that has been processed by the system unit and present the information on paper. Headphones are a form of audio-output devices. These devices translate audio information from the computer into sounds that people can understand. They are used for things such as playing music. Differentiate between primary and secondary storage. Primary storage, also known as memory, holds data and programs but if the electricity is lost all the information is lost. Secondary storage also holds data and programs, however if the electricity is lost the information is saved. Secondary storage is used as a backup storage....
