  5. 5. Desktops and Mobile Computers • A personal computer (PC) is a computer that can perform all of its input, processing, output, and storage activities by itself and is intended to be used by one person at a time • A mobile computer is a portable personal computer, designed so that a user easily can carry it from place to place
  6. 6. Desktops and Mobile Computers • A desktop, or desktop computer, is a personal computer designed to be in a stationary location, where all of its components fit on or under a desk or table
  7. 7. Desktops and Mobile Computers • A laptop, also called a notebook computer, is a thin, lightweight mobile computer with a screen in its lid and a keyboard in its base
  8. 8. Desktops and Mobile Computers • A tablet is a thin, lightweight mobile computer that has a touch screen
  9. 9. Desktops and Mobile Computers • A handheld computer is a computer small enough to fit in one hand
  10. 10. Servers • A server is a computer dedicated to providing one or more services to other computers or devices on a network • Rack server • Blade server • Tower server
  11. 11. Servers
  12. 12. Servers • A mainframe is a large, expensive, powerful server that can handle hundreds or thousands of connected users simultaneously
  13. 13. Supercomputers • A supercomputer is the fastest, most powerful computer — and the most expensive
  14. 14. Terminals • A terminal is a computer, usually with limited processing power, that enables users to send data to and/or receive information from a server, or host computer • A thin client is a terminal that looks like a desktop but has limited capabilities and components • Most retail stores use a POS terminal to record purchases, process credit or debit cards, and update inventory
  15. 15. Terminals • An ATM (automated teller machine) is a self- service banking terminal that connects to a host computer through a network
  16. 16. Terminals • A self-service kiosk is a freestanding terminal that usually has a touch screen for user interaction
  17. 17. Cloud Computing • Cloud computing refers to an environment of servers that house and provide access to resources users access through the Internet
  18. 18. Mobile Devices • A smartphone is an Internet-capable phone that usually also includes a calendar, an appointment book, an address book, a calculator, a notepad, games, browser, and numerous other apps • Many smartphones have touch screens. Instead of or in addition to a touch screen, some have a built-in mini keyboard on the front of the phone or a keyboard that slides in and out from behind the phone
  19. 19. Mobile Devices • A digital camera is a mobile device that allows users to take photos and store the photographed images digitally
  20. 20. Mobile Devices
  21. 21. Mobile Devices • A portable media player, sometimes called a personal media player, is a mobile device on which you can store, organize, and play or view digital media
  22. 22. Mobile Devices • A digital media player or streaming media player is a device, typically used in a home, that streams digital media from a computer or network to a television, projector, or some other entertainment device.
  23. 23. Mobile Devices • An e-book reader (short for electronic book reader), or e- reader, is a mobile device that is used primarily for reading e- books and other digital publications
  24. 24. Mobile Devices • A wearable device is a small, mobile computing device designed to be worn by a consumer. These devices often communicate with a mobile device or computer using Bluetooth. Three popular types of wearable devices are activity trackers, smartwatches, and smartglasses.
  25. 25. Game Devices • A game console is a mobile computing device designed for single-player or multiplayer video games • A handheld game device is a small mobile device that contains a screen, speakers, controls, and game console all in one unit • Game controllers include gamepads, joysticks and wheels, dance pads, and a variety of motion- sensing controllers
  26. 26. Game Devices
  27. 27. Embedded Computers • An embedded computer is a special-purpose computer that functions as a component in a larger product Consumer electronics Home automation devices Automobiles Process controllers and robotics Computer devices and office machines
  28. 28. Embedded Computers
  29. 29. Putting It All Together
  30. 30. Ports and Connections • A port is the point at which a peripheral device attaches to or communicates with a computer or mobile device so that the peripheral device can send data to or receive information from the computer or mobile device • A connector joins a cable to a port. A connector at one end of a cable attaches to a port on the computer or mobile device, and a connector at the other end of the cable attaches to a port on the peripheral device
  31. 31. Ports and Connections
  32. 32. Ports and Connections • A USB port, short for universal serial bus port, can connect up to 127 different peripheral devices together with a single connector • Instead of connecting peripheral devices directly to ports on a mobile computer, some mobile users prefer the flexibility of port replicators and docking stations
  33. 33. Ports and Connections
  34. 34. Ports and Connections • Instead of connecting computers and mobile devices to peripheral devices with a cable, some peripheral devices use wireless communications technologies Bluetooth Wi-Fi NFC
  35. 35. Protecting Hardware • Some schools and businesses use cables to lock computers and help prevent theft of equipment
  36. 36. Protecting Hardware • Some mobile computers and devices include fingerprint readers, which can be used to verify a user’s identity.
  37. 37. Protecting Hardware • Hardware can fail for a variety of reasons: aging hardware; random events such as electrical power problems; and even errors in programs or apps • Undervoltage • Overvoltage or power surge • A surge protector, also called a surge suppressor, uses electrical components to provide a stable current flow and minimize the chances of an overvoltage reaching the computer and other electronic equipment
  38. 38. Protecting Hardware • An uninterruptible power supply (UPS) is a device that contains surge protection circuits and one or more batteries that can provide power during a temporary or permanent loss of power
