NETWORKING

TCP/IP Layer model
Application Layer
-
defines how data is presented to the user and which protocols are used for different types of communication, like web browsing, file transfer, or email.
Example: When you type google.com.au into your browser, the Application Layer handles how the request is sent using the HTTP protocol.
Transport layer
-
manages the communication between two devices using protocols like TCP (Transmission Control Protocol). TCP ensures that data packets arrive correctly.
Example: When you send a message, TCP breaks it into smaller data packets and ensures that each packet reaches the recipient and is reassembled in the correct order.
Internet layer
responsible for moving data packets across different networks and ensuring they reach the right destination.
-
Example: When you visit a website, the Internet Layer ensures that your request (as data packets) is sent to the correct server using IP addresses.
Network access layer
-
includes the hardware, such as Ethernet cables or Wi-Fi signals, and deals with how data is transmitted between your device and the router or modem.
