    Study Notes

    Network Protocols

    • Network protocols define how messages are exchanged between the source and the destination.
    • Standards help products from different manufacturers interoperate.
    • Three layers of the OSI model (Application, Presentation and Session) are comparable in function to the application layer of the TCP/IP model.
    • An IP address is encapsulated at the network layer of the OSI model.
    • A segment is processed when a host computer is de-encapsulating a message at the transport layer of the TCP/IP model.
    • Layer 4 of the OSI model is responsible for the ordered and reliable delivery of data between source and destination.
    • A protocol data unit is the general term used to describe a piece of data at any layer of a networking model.

    Networking Devices

    • A router is a device that determines the path that messages should take through internetworks.
    • The environment where the selected medium is to be installed is one of the criteria used to select a network medium.

    Networking Devices

    • A router determines the path that messages should take through internetworks.
    • When selecting network media, consider the environment where the selected medium is to be installed.
    • Intermediary devices connect individual hosts to the network.
    • End devices originate the data that flows through the network.
    • An intranet is a private network that is used by employees of an organization.
    • Satellite, dialup, and dedicated leased lines are Internet connection options that do not require physical cables to be run to the building.
    • BYOD is a networking trend that involves the use of personal tools and devices for accessing resources on a business or campus network.
    • A converged network delivers data, voice, and video over the same network infrastructure.
    • Cloud computing allows applications to be accessed over the Internet by individual users or businesses using any device, anywhere in the world.
    • With powerline networking technology, a device connects to an existing home LAN using an adapter and an existing electrical outlet.

    Network Security

    • Implementing a firewall and installing antivirus software provide minimum security requirements for a small office network.
    • Video conferencing requires QoS (Quality of Service).
    • Using strong, complex passwords supports data confidentiality.

    Network Characteristics

    • A scalable network grows in size without impacting existing users.
    • A broadcast message is sent to all devices on a local area network.
