Networks
  1. What is a network?
    1. A network is an interconnected collection of computers
    2. Types of Networks?
      1. LAN- Local Area Network
        1. WAN- Wide Area Network
          1. MAN- Metropolitan Area Network
          2. What is a topology?
            1. The arrangement of computers in a network.
              1. Examples of topologies
                1. Star
                  1. Pro: If one system breaks, it does not effect the network
                    1. Con: it is dependent of the central computer, and wiring is expensive.
                    2. Ring
                      1. Pros: Easy to access/transmit data. Doesn't require server and works better than a star.
                        1. Cons: One malfunctioning node can stop the whole network. It is slower than Ethernet too. Moving, adding, and changing devices can be straining.
                        2. Bus
                          1. Pros: If one node fails, the others are not affected. Simple and easy to set up.
                            1. Cons: If the cable malfunctions, the network goes down. Cables and number of nodes are limited.
                            2. Hierarchial
                              1. Cons: If one node fails, the others fail as well
                                1. Pros: Data can be easily shared as all nodes are interconnected to one another.
                            3. Parts of a Network
                              1. Cables
                                1. Connectors
                                  1. Network Software
                                    1. Network Interface Card
