PPP & SLIP

PPP - Point to Point Protocol - RFC 1968

- Method of connecting to the Internet

- Communication between two Computer(You and your ISP Server) via Serial Interface

- Provides error checking

- It can provide encryption

- Layer 2 Data Link in the OSI Model

- Full-Duplex

Your Computer >>> ISP Server >>> Internet

SLIP - Serial Line Internet Protocol - RFC 1055

- Communication via Dial Up

- Max speed of 2400bps

- This Protocol was before PPP

- No Encryption or Error Checking
