Internet protocols

Internet protocols

1. A network protocol defines how all of the operations within and out of the network interact.

2. IP- a unique address that identifies a computer.

3. The TCP protocol takes the data from the users application and passes it to the IP protocol

   • The IP protocol then organises the data into packets and sends it across the internet.
     • The IP then receives the data on the other side and transmits it across a network
       • The IP passes it to the TCP protocol which gives it back to the recipient.

4. The FTP protocol is good for uploading and downloading large files ONLY! It can be slower than the HTTP protocol as the HTTP protocol can download multiple files within the same connection. It also has increased security benefits because it can download encrypting files.

   • FTP and https tell the URL what to do with the webpage.

5. https keeps you safe and secure online- it is combined with SSL which makes sure all purchases are secure.
