CMW Chapter 9

  1. A _ covers a large geographic area, such as a city, country, or the world, using a communications channel that combines many types of media.
    Wide Area Network (WAN)
  2. The _ is...
    a. the design of computers, devices, and media in a network
    b. categorized as either client/server or peer to peer
    network architecture
  3. A _ server is a dedicated server that stores and manages files.
  4. A _ is a legal document that permits users to install software on multiple computers, usually at a volume discount.
    site liscence
  5. A _ is a network that connects computers and devices in a limited geographical area, such as a home, school computer laboratory, or office building.
    local area network (LAN)
  6. Each computer or device on a local area network, called a _, often shares resources such as printers, large hard disks, and programs.
  7. A _ is a high-speed network that connects networks in an area such as a city or town and handles the bulk of comminications activity across that region.
    metropolitan area network (MAN)
  8. A _ server is a dedicate server that manages printers and print jobs.
  9. A _ server is a dedicated server that stores and prvides access to a database.
  10. A _ server is a dedicated server that manages network traffic activity.
  11. _ topology...
    -a cable forms a closed loop
    -all computers and devices are arranged along the loop
    -if one node fails, the other computers are also affected
  12. _ Topology...
    -all of the computers and devices (nodes) on the network are connected to a single wire
    -if one node fails, the network goes down
  13. _ Topology...
    -all of the computers and devices (nodes) on the network are connected to a central device.
    -the central device that provies a common connection point for nodes on the network is called the _.
    -if one node fails, only that node is affected. the rest of the network is okay.
    -most schools and buisnesses use this type of network.
  14. _ is the most popular LAN technology because it is relatively inexpensive and easy to install and maintain.
  15. _ has been adopted as a network standard for Internet communications.
    TIP/IP (Transmission control protocol/internet protocol)
  16. When a computer send data over the Internet, the daata is divided into small pieces, or _.
  17. Each _ computer in a house can...
    -share a single high-speed Internet connection
    -access files and programs on other computers in the house
    -share peripherals such as a printer, scanner, external hard disk, or DVD drive.
  18. A _ is a LAn that uses no phyisical wires.
    WLAN (wireless local area network)
  19. A _ is a an adapter card, PC card, or flash card that enables a computer or device to access a network.
    NIC (network interface card)
  20. _ is...
    -the ammount of data, instructions, and information that can travel over a communications channel
    -determined by the amount of traffic or usage at one given time
  21. _ is the time it takes a signal to travle fomr one location to another on a network.
  22. The _ is the world's largest WAN (wide area network)
  23. On a network a _...
    -controls access to the hardware, software, and other resources on the network.
    -provides a centralized storasge area for programs, data, and information.
    host computer
  24. _ technology uses short-range radio waves to transmit data between two devices.
  25. _ is a newer networlk standard developed by IEEE that specifies how woreless devices communicate over air in a wide area.
