  6. 6.  A Network is a system of two or more computers that are connected through a series of cables Examples: Infrared light beams, satellite connections, wireless towers, or telephone linesSource: Image Courtesy of Microsoft Clip Art
  7. 7. The Local Area Network (a.k.a) LAN is a… Smaller network limited to a geographic setting. The computers are connected through cables. Examples: 1 Home or 1 School computer lab or librarySource: Screen shot Image Courtesy of Microsoft Clip Art
  8. 8. The Wide Area Network(WAN) is… Any area over 30 miles It connects a larger geographic area Examples: Arkansas, the United States, and the Global World Includes global networks(e.g. The Internet)Source: Image Courtesy of Microsoft Clip Art
  9. 9.  The MAN network is the Metropolitan Area Network. It has a span of 30 miles Its reach is about 2 buildingsSource: Screenshot Courtesy of: Learn-networking.com
  10. 10.  A Workstation is a personal home computer It can be a desktop computer used in a business. It connects human beings together through the use of the desktop computer. E.g. A Tokyo stockbroker communicates with a Wall Street stockbroker through email communication.
  11. 11.  A Node is a device that is connected to a computer Example: Printer, Scanner, Server, Laptop The Internet is not required within a network Most Common Node: Desktop Style computer(Workstation)Source:
  12. 12.  A Cluster is a group of server operating systems. Computers connected to be viewed as a “Single System” Within a Local Area Network (LAN) Runs on its own operating system Screenshot Courtesy of Cluster Computing
  13. 13.  Client: A Part of the network that receives the data. Host: A part of the network that gives the data. The data is accessed from the Host
  14. 14.  Server: The same data or information different users receive. E.g. Five different people in various countries search for the word Red Rose in the Google Search Engine and they all receive the same results. Network Interface Cables (NIC): A card that is installed in a computer that allows wireless or Ethernet cable usage to access the internet.
