Chapter 19 Vocabulary In a bulleted list, type the following vocabulary words and their definitions • Computer • Ergonomics • E-learning • Hardware • Random access memory (RAM) • Software • Operating system • Word processing • Spread sheet • Database management • Presentation program • Desktop publishing

  3. The Importance of Computers • People depend on computers to handle all kinds of tasks. • Paying bills online • Buying gas • Withdrawing money from the bank • Businesses of all sizes use computers to collect data and keep track of records.

  4. Computers for Business • A personal computer (PC) is a small computer that is intended to be used by one person. • A desktop computer is a personal computer that is small enough to fit in an individual work space. • Top PC makers • Dell • Hewlett-Packard • Apple is also a leading computer maker; however, its MacIntosh systems are considered “Macs” rather than PCs.

  5. Computers for Business • In most companies, computers are linked through either a central mainframe computer or a network. • A mainframe is a fast powerful computer with a large storage capacity. • Linking workstations allows users to share files, data, and printers, send e-mails, and access the Internet.

  6. The Computer Workstation • A well-organized computer workstation is important for both business and home use. • Well-designed workstations can help workers: • reduce stress • avoid straining their eyes, neck, shoulders, and wrists • Increases efficiency

  7. The Computer Workstation • To create a safe and comfortable computer workstation: • Place the tools you need most, close to you. • Place your monitor at or just below eye level and at arm’s length. • Keep your wrists straight when you type. • Use a chair that is adjustable, and keep it at a height that suits you. • Position your chair so that it supports your lower back. • Keep your feet flat on the floor or on a footrest.

  8. Computers As Learning Tools • Businesses also use computers to provide workers with the information, tools, and training they need to do their job. • Some training companies specialize in online education and tutorials for workers. • Training with simulation software lets employees practice new task at their own pace. • E-learning allows workers to be trained in an efficient and cost effective way.

  9. Parts of a Computer System • 3 main parts to a computer system: • Hardware • Microprocessor • Memory • Input/Output devices • Data and storage devices • Software • Data • Characters • Sounds • Graphics • numbers

  10. Microprocessors • A microprocessor is a small computer chip, the brain of the computer. • It is also called the CPU (Central Processing Unit). • Receives instructions and carries them out at extremely high speeds. • Each chip contains millions of circuits for data storage.

  11. Microprocessors • Examples of devices that use computer chips: • calculators • PDAs • Electronic toys • Mobile phones

  12. Memory • Memory is hardware that stores information for instant retrieval and processing. • When a computer is using information, it stores it in random access memory. • As soon as you turn off the computer, RAM loses information

  13. Input & Output Devices • An input device is hardware that is used for entering data into a machine, such as a computer. • Input devices include: • Keyboards • Computer mice • Touchpads • Joysticks • scanners

  14. Input & Output Devices • An output device is hardware that is used for producing results from a machine. • Output devices include: • Computer monitors • Printers • Fax machines • speakers

  15. Data Storage Devices • Data storage devices save information for later use. • Data storage devices include: • CD-ROM drives • DVD drives • Portable storage devices are also popular because they can be easily moved from one machine to another. • Disks • Flash drives • DVDs

  16. Data Storage • Data storage is measured in: • 1 Kilobyte: 1,024 bytes • 1 Megabyte: 1,024 kilobytes • 1 Gigabyte: 1,024 megabytes • 1 Terabyte: 1,024 gigabytes

  17. What is hardware? • The physical parts of a computer. • Hardware can be external or internal. • External: located outside of the system unit • Internal: located inside the system unit of the computer

  18. Printer Keyboard Mouse Head Set Speakers Headphones Monitor Tower External Hardware • **All external hardware must be connected to the tower through a port.

  19. Parts of the Computer Worksheet

  20. Internal Hardware: located inside • Power Supply: provides the electricity for the computer • to run • Video Card: controls the graphics that are displayed on the monitor • Modem: connects computers to a network and allows them to communicate through the internet • RAM: Random Access Memory • Temporary location for computer to hold data

  21. Internal Hardware • Motherboard: Main circuit board of a computer • All computer system components connect to it. • BIOS: Basic Input/Output System • Wakes up computer and reminds it what to do. • Hard Drive: Information in the computer is stored here • on magnetic cylinders • CPU: Central Processing Unit • The brains of the computer. • Floppy Disk Drive, CD-ROM Drive, Sound Card

  24. Software Programs • Computers are just machines and require instruction from people. • Software is referred to as a program or an application.

  25. What is software? • The instructions, also called computer programs, • that are used to tell a computer what it should do. • What software have you used?
