Communication between
Computers
� Connectionless Communication
� Do not guarantee delivery
� Faster compared to connection-oriented
� Example: ordinary postal service� Example: ordinary postal service
� IP, UDP, IPX
� Connection-Oriented Communication
� Guarantee delivery
� Slower compared to connectionless
� Example: Registered Courier
� TCP, SPX, X.25

� SLIP: Serial Line Internet Protocol
� Used to transmit IP packet over serial lines and telephone connections
� As part of dial-up connection� As part of dial-up connection
� Supports TCP/IP only
� Do not support encryption
� PPP: Point-to-Point Protocol
� Used to transmit IP packet over serial lines and telephone connections
� Supports multiple protocols
� Support encryption
