1 Rev.Confirming Pages VISUAL SUMMARY Information Technology, the Internet, and You INFORMATION SYSTEMS The way to think about a microcomputer is to realize that it is one part of an information system. There are several parts of an information system: People are an essential part of the system. The purpose of information systems is to make people, or end users like you, more productive. Procedures are rules or guidelines to follow when using software, hardware, and data. They are typically documented in manuals written by computer professionals. Software (programs) provides step-by-step instructions to control the computer to convert data into information. Hardware consists of the physical equipment. It is controlled by software and processes data to create information. Data consists of unprocessed facts including text, numbers, images, and sound. Information is data that has been processed by the computer. Connectivity allows computers to connect and share information. To be computer competent, end users need to understand information technology (IT), including software, hardware, data, and connectivity. PEOPLE People are the most important part of an information system. This book contains several features to demonstrate how people just like you use computers. These features include the following: Making IT Work for You presents several interesting and practical applications. Topics include using digital video editing and locating job opportunities. Tips offer a variety of suggestions on such practical matters as how to improve slow computer performance and how to protect your privacy while on the web. Explorations direct you to important information and websites that relate to computers and technology. Ethics boxes pose a variety of different ethical/ unethical situations for your consideration. Environment discusses important and relevant environmental issues. The impact of computers and other technologies is more critical today than ever before. Careers in IT presents job descriptions, employment demands, educational requirements, salary ranges, and advancement opportunities. Computing Essentials website integrates the textbook with information on the web, including animations, career information, tips, test review materials, and much more. Information Technology, the Internet, and You ole16864_ch01_ indd /9/12 2:42 PM
2 Rev.Confirming Pages To prepare for your future as a competent end user, you need to understand the basic parts of an information system: people, procedures, software, hardware, data, and connectivity. Also you need to understand the Internet and the web and to recognize the role of technology in your professional and personal life. SOFTWARE Software, or programs, consists of system and application software. System Software System software enables application software to interact with computer hardware. Operating systems coordinate resources, provide an interface, and run applications. Utilities perform specific tasks to manage computer resources. Device drivers are specialized programs to allow input and output devices to communicate with the rest of the computer system. Application Software Application software includes general-purpose, specialized, and mobile applications. General purpose widely used in nearly all career areas; programs include browsers, word processors, spreadsheets, database management systems, and presentation graphics. Specialized focus more on specific disciplines and occupations; programs include graphics and web authoring. Mobile apps designed for mobile devices; most popular are for text messaging, Internet browsing, and connecting to social networks. 20 HARDWARE Hardware consists of electronic devices that can follow instructions to accept input, process the input, and produce information. Types of Computers Supercomputer, mainframe, midrange (server), and microcomputer are four types of computers. Microcomputers can be desktop, notebook (laptop computer), tablet, or handheld (PDAs and smartphones are the most widely used handheld microcomputers). Microcomputer Hardware There are four basic categories of hardware devices. System unit contains electronic circuitry, including the microprocessor and memory. Random-access memory (RAM) holds the program and data currently being processed. Input/output devices are translators between humans and computers. Input devices include the keyboard and mouse. Output devices include monitors and printers. Secondary storage holds data and programs. Typical media include hard disks, solid-state storage (solid-state drives, flash memory cards, and USB drives), and optical discs (CD, DVD, and Blu-ray). Communication devices allow microcomputers to communicate with other computer systems. Modems modify audio, video, and other types of data for transmission and processing.

3 Rev.Confirming Pages DATA CONNECTIVITY Data is the raw unprocessed facts about something. Common file types include Document files created by word processors. Connectivity Connectivity describes the ability of end users to use resources well beyond their desktops. The Wireless Revolution The wireless revolution is the widespread and increasing use of mobile (wireless) communication devices. Internet The Internet is the world s largest computer network. The web provides a multimedia interface to resources available on the Internet. Worksheet files created by spreadsheet programs. Cloud Computing Cloud computing uses the Internet and the web to shift many activities from users computers to computers on the Internet. CAREERS IN IT Database files created by database management programs. Career Description Webmaster Develops and maintains websites and web resources. See page 51. Software engineer Analyzes users needs and creates application software. See page 82. Computer support specialist Provides technical support to customers and other users. See page 112. Computer technician Repairs and installs computer components and systems. See page 141. Technical writer Prepares instruction manuals, technical reports, and other scientific or technical documents. See page 174. Network administrator Creates and maintains computer networks. See page 229. Presentation files created by presentation graphics programs.
