Chapter 1
- 5 aspects of networking
- network applications and
network programming
- data communications
- study of low-level mechanisms and
technologies used to send information
across a physical communication medium
- physical media influence protocol design
- study of low-level mechanisms and
technologies used to send information
across a physical communication medium
- packet switching and
networking technologies
- instead of forming a dedicated circuit,
packet switching allows senders to
transmit data over a shared network
- divides data into blocks
and includes information
about the intended
recipient in each packet
- instead of forming a dedicated circuit,
packet switching allows senders to
transmit data over a shared network
- internetworking with TCP/IP
- TCP/IP
- internet
protocol
suite
- goal: interconnect many packet switching
technologies into a functioning whole
- internet

- TCP/IP's
relevance rests in
its ability to
subsume new
technologies as
they emerge
