章节摘录

插图：PeopleWhen one computer system is set up to communicate with another computer system, connectivity beeomes a sixth system element. In other words, the manner in which the various individual systems are connected-for example, by phone lines, microwave transmission or satellite-is an element of the total computer system.Software is the term used to describe the instructions that tell the hardware how to perform a task; without software instructions,the hardware doesn't know what to do. People operate the computer hardware ; they create the computer software instructions and respond to the procedures that those instructions present. You will learn more about software and procedures later. Right now we want to discuss the importance of data and information.The purpose of a computer system is to convert data into information. Data is raw, unevaluated facts and figures, concepts, or instructions. This raw material is processed into useful information. In other words, information is the product of data processing. This processing includes refining, summarizing, categorizing, and otherwise manipulating the data into a useful form for decision making. For example, the facts and figures contained in a stack of customer orders waiting to be entered into a computer-based order entry system are data; after the data is entered and processed, an output report about how that data affected product inventory would be information.People "capture" data in a variety of ways——for example, by reading, listening, or seeing. Then they may record the data on a document. For instance, Roger 5hu records his name on an employee timecard by first entering the letter R. This letter,and each of the remaining letters in his name, is an element of data,as are the numbers 12/22 and 5, used to indicate the date and the number of overtime hours worked. By themselves, these data elements are useless;we must process .
