    Study Notes

    Network Protocols

    • Network protocols define how messages are exchanged between source and destination.
    • Standards are important for developing and implementing protocols because they allow products from different manufacturers to interoperate successfully.

    OSI Model Layers

    • The Application layer of the OSI model is similar to the Application layer of the TCP/IP model.
    • The Presentation and Session layers of the OSI model are also similar to the Application layer of the TCP/IP model.
    • An IP address is encapsulated at the Network layer of the OSI model.

    TCP/IP Model

    • The Transport layer of the TCP/IP model processes segments.
    • Layer 4 of the OSI model is responsible for describing the ordered and reliable delivery of data between source and destination.
    • A protocol data unit (PDU) is a general term for a piece of data at any layer of a networking model.

    Network Devices

    • A router determines the path that messages should take through internetworks.
    • End devices originate data that flows through the network.
    • Intermediary devices connect individual hosts to the network.

    Network Types

    • An intranet is a private network used within a company or organization.
    • The Internet is a global network that connects computers and networks worldwide.
    • An extranet allows authorized outside users access to a company's internal network.
    • A local area network (LAN) connects computers and devices within a limited geographical area.
    • Bring Your Own Device (BYOD) allows employees to use their personal devices to access resources on a business or campus network.
    • Converged networks deliver data, voice, and video over the same network infrastructure.
    • Cloud computing allows applications to be accessed over the Internet by any device, anywhere in the world.
    • Powerline networking uses existing electrical wiring to extend an existing home LAN.

    Network Security

    • Implementing a firewall and antivirus software offer minimal security requirements for a small office network.
    • Quality of Service (QoS) is required for network traffic that needs priority, like video conferencing.

    Network Scalability

    • A scalable network can grow in size without impacting existing users.

    Network Communication

    • Broadcast communication sends a message to all devices on a local area network.
    • Encapsulation is the process of placing one message inside another message for transfer.

    Protocol Stack

    • The correct order of the protocol stack used to prepare a web request for transmission from the client's perspective is: HTTP, TCP, IP, Ethernet.
