Ch4:1.Desktop publishing programs mix text and graphics to createprofessional publications.Image editors create and modify bitmap image files.Illustration programs modify vector images.Image galleries are libraries of electronic images, widely available from the Web.A graphics suite is a collection of individual graphics programs sold as a unit.2.Video editing software allows you to reorganize, add effects, and moreto digital video. Audio editing software allows you to c reate and edit audio clips. You can add audio effects, like filters, to your tracks.3.Multimedia integrates all sorts of media, including video, music, voice,graphics, and text into one presentation.The creation of multimedia presentations involves four steps:Plan and analyze, design, create, and support.4.Creating a site is called Web authoring. Web sites are an interactivemultimedia form of communication.Web authoring programs are specifically designed to create Web sites.5.Three areas are virtual reality, knowledge-based system, and robotics. VR creates computer-generated simulated environments. Knowledge-based (expert) systems are programs that duplicate the knowledge that humans use to perform specific tasks. Robotics is concerned with developing and using robots.Ch5：1.System software works with end users, application software, andcomputer hardware to handle the majority of technical details. Operating systems, Utilities, Device drivers and Language translators. 2.Operating systems’ functions include managing resources, providing auser interface, and running applications between different applications stored in memory.Three categories of operating systems are Embedded, Network, Stand-alone.3.Windows, Mac OS, and Linux are all OS.Windows is the most widely used operating system. It designed to runwith Intel and Intel-compatible microprocessors. Mac OS is an innovative, powerful, easy-to –use operating system; designed to run with Macintosh computers. UNIX was originally designed to run on minicomputers in network environments.4.Utilities are specialized programs designed to make computing easier. Troubleshooting, Antivirus programs, uninstall programs, backup programs.Utility suites combine several programs into one package.5.Device driver works with the operating system to allowcommunication between the device and rest of the computer system. Windows’Add Printer Wizard provides step-by-step guidance for selecting the appropriate printer driver and installing that driver. Windows Update automates the process of updating device drivers.Ch6：1.Four basic types are: desk-top, notebook, tablet PC, and handheld. Desktop system units contain the system’s electronic components and selected secondary storage devices.Notebook system units contain the electronic components, selected secondary secondary storage devices, and input devices.Tablet PC system units are highly portable devices that support the use ofa stylus or pen to input commands and data.2.It has two basic components: the control unit and the arithmetic-logicunit. The control unit tells the rest of the computer system how to carry out a program’ instructions. The arithmetic-logic unit performs arithmetic and logical operations.3.Memory holds data, instructions, and information. There are threetypes of memory chips:RAM chips hold the program and data is presently processing. RAM are temporary or volatile because their contents are lost if power is disrupted. ROM chips have programs built into them at the factory. They are nonvolatile storage and control essential system operations.CMOS chip provide flexibility and expandability to computer systems.4.●Graphics cards connect the system board to the computer’s monitor.●Sound cards accept audio input from a microphone and c onvert it intoa form that can be processed by the computer.●Modem cards allow distant computers to communicate with eachother.●Network interface cards are used to connect a computer to one ormore other computers.●TV tuner cards changes the TV signal into one that can be displayedon your monitor.5.●Serial ports are used to connect many devices to the system unit.●Parallel ports are used to connect external devices that need tosend or receive a lot of data over a short distance.●Universal serial bus ports are faster and can be used to connectseveral devices to the system unit.●FireWire ports provide connections to specialized FireWiredevices such as camcorders.Tow specialty ports:MIDI ports are used to connect musical instruments such as electronic keyboards.IrDA ports provide wireless mechanism for transferring data between devices.Ch7：1.Input devices translate words, images, and actions into a form acomputer can process.Output is data or information processed by a computer. Output devices translate processed text, graphics, audio, and video into a form humans can understand.2.P2023.P203-2044.Output is data or information processed by a computer. Output devices translate processed text, graphics, audio, and video into a form humans can understand.bination devices combine input and output capabilitiesFax Machines send and receive images via standard telephone lines.Multifunctional devices typically combine the capabilities of a scanner, printer, fax, and copy machine.Internet Telephones receive and send voice communication.Terminals are input and output devices that connect to a mainframe or other type of computer.。
