  • Ref:understanding computers 12th edition
  • Fifth-generation (now and the future)Infancy stageNo precise classificationMay be based on artificial intelligence (AI)Likely use voice inputMay be based on optical computers and utilize nanotechnology
  • Input devices-Used to input data into the computer-Keyboards, mice, scanners, cameras, microphones, joysticks, etc.Processing devices-Perform calculations and control computer’s operation-Central processing unit (CPU) and memoryOutput devices-Present results to the user-Monitors, printers, speakers, projectors, etc.Storage devices-Used to store data on or access data from storage media-Hard drives, DVD disks and drives, USB flash drives, etc.Communications devices-Allow users to communicate with others and to electronically access information -Modems, network adapters, etc.
  • Software: The programs or instructions used to tell the computer hardware what to doSystem software: Operating system allows a computer to operateBoots the computer and launches programs at the user’s directionMost use a GUI to interact with the user via windows, icons, menus, buttons, etc.Windows, Mac OS, Linux, etc.
  • Application software: Performs specific tasks or applicationsCreating letters, budgets, etc.Managing inventory and customer databasesEditing photographsScheduling appointmentsViewing Web pagesSending and receiving e-mailRecording / playing CDsDesigning homesPlaying games
  • Computer network: A collection of hardware and other devices that are connected together.-Users can share hardware, software, and data-Users can communicate with each otherNetwork servers: Manage resources on a networkClients: Access resources through the network serverComputer networks exist in many sizes and types-Home networks-School and small business networks-Large corporate-Public wireless networks-The Internet
  • Internet: The largest and most well-known computer network in the worldIndividuals connect to the Internet using an Internet service provider (ISP)World Wide Web: One resource (a vast collection of Web pages) available through the Internet-Web sites contain Web pages stored on Web servers-Web pages viewed using a Web browser (Internet Explorer, Safari, Firefox, Opera, etc.A wide variety of information is available through the Web

    3. 3. computer in education• Schools now use the computer as an overall student-based learning tool• Universities are even more integrated [Classrooms, computer labs, dorms, libraries / Wireless hotspots and Internet assignments]• Lecturers/Teachers [Prepare handouts, exams, and class presentations / Maintain course Web pages• Distance learning [Students participate from locations other than the / raditional classroom setting using computers and Internet access]
    4. 4. computer in workplaceComputers have become a universal on-the-job tool for decision-making, productivity, and communication:• Used by all types of employees• Used for access control and other security measures• Use by service professionals is growing• Used extensively by the military• Employees in all lines of work need to continually refresh their computer skills
    5. 5. computer on the goComputers are encountered in nearly every aspect of daily life• Portable PCs and handheld computers• Wi-Fi hotspots and Internet cafes• ATM machines and retail stores• Self-checkout systems and consumer kiosks• M-commerce systems• GPS systems
    6. 6. what is a computer and what does itdo?• A programmable, electronic device that accepts data, performs operations on that data, and stores the data or results as needed• basic operations: input data > process data > store data > communicate data
    7. 7. Computer HardwareHardware: The physical parts of a computer• Internal hardware [Located inside the main box (system unit) of the computer]• External hardware [Located outside the system unit and plug into ports located on the exterior of the system unit]Hardware associated with all five computer operations
