Study Notes

TCP/IP and OSI Models

The OSI model was designed to describe the functions of a communication system by dividing it into smaller, simpler components.
The TCP/IP model, on the other hand, was designed and developed by the Department of Defense (DoD) in the 1960s and is based on standard protocols.

Layers of the TCP/IP Model

The TCP/IP model consists of four layers:
- Process/Application Layer
- Host-to-Host/Transport Layer
- Internet Layer
- Network Access/Link Layer

Comparison of TCP/IP and OSI Models

TCP/IP has 4 layers, whereas OSI has 7 layers.
TCP/IP is more reliable, whereas OSI is less reliable.
TCP/IP does not have strict boundaries, whereas OSI has strict boundaries.
TCP/IP follows a horizontal approach, whereas OSI follows a vertical approach.
TCP/IP uses both session and presentation layers in the application layer itself, whereas OSI uses different session and presentation layers.

TCP and Transport Layer

TCP (Transmission Control Protocol) is used to communicate with a web server.
TCP breaks up the web page into manageable chunks, labels them with numbers, and transports the pieces across the correct session.

IP and Network Layer

IP (Internet Protocol) is a network layer protocol that uses unique addresses for the web server and the computer.
IP provides the means for the computer to determine whether the web server is local or on the Internet.
IP allows the computer to figure out how to reach the Internet web server via the default gateway.

Network Access/Link Layer

The network access/link layer is responsible for converting the web request into a message that is sent from the computer to the default gateway.
This layer uses protocols such as Ethernet, LLC, and MAC to transmit the data.
