ICT259: The OSI Reference Model and TCP/IP Protocol Model are both abstract descriptions for layered communications: Computer Networking Report, SUSS, Singapore

The OSI Reference Model and TCP/IP Protocol Model are both abstract descriptions for layered communications and computer network protocol design. They are used to standardize and characterize functions of communication systems and ensure the operability of various communication systems. Therefore, you can see their application in all kinds of computer network communications.

Identify one computer network communication: 

• Place an online food delivery order on a mobile phone to the server.
• Send a picture via Bluetooth to a friend.
• Sharing a file through peer-to-peer software.
• Validate a blockchain transaction.

Use either OSI or TCP/IP model to explain the process from communication between source and destination, how the data flow from one layer to another, and between the end devices and intermediate devices in the network
