Study Notes

OSI Model

  • The OSI model is a reference model from the International Organization for Standardization (ISO) that provides a common basis for the coordination of standards development for the purpose of systems interconnection.

Layers of the OSI Model

  • The application layer is used by end-user software such as web browsers and email clients, providing protocols like HTTP, FTP, POP, SMTP, and DNS.

  • The presentation layer prepares data for the application layer, defining how to encode, encrypt, and compress data.

  • The session layer creates communication channels (sessions) between devices, opening and closing them as needed, and setting checkpoints during data transfer.

  • The transport layer takes data, breaks it into segments, and reassembles them on the receiving end, carrying out flow control and error control.

  • The network layer breaks up segments into network packets, routes packets using network addresses (like IP addresses), and reassembles them on the receiving end.

  • The data link layer establishes connections between physically-connected nodes, breaking up packets into frames and sending them from source to destination.

  • The physical layer is responsible for the physical cable or wireless connection, defining the connector, electrical cable or wireless technology, and transmission of raw data.

Advantages of OSI Model

  • Helps determine required hardware and software to build a network.
  • Helps understand and communicate the process followed by components communicating across a network.
  • Aids in troubleshooting by identifying which network layer is causing an issue.

TCP/IP Model

  • Is older than the OSI model and was created by the US Department of Defense (DoD).
  • Combines OSI layers 5, 6, and 7 into one Application Layer.
  • Combines OSI layers 1 and 2 into one Network Access Layer.

IP Addresses

  • An Internet Protocol (IP) address is a unique numerical identifier for every device or network that connects to the internet.
  • IP addresses can be static (assigned to a device and remaining constant) or dynamic (changing each time a device connects to the internet).
  • Class A addresses are for networks with a large number of total hosts.
