The objective of this lesson is to provide a general
overview of the Open Systems Interconnection (OSI) Reference Model that modern
computer networks are modeled after, with particular attention to TCP/IP
networks (the Internet). At the end of
this lesson, students should be able to:
1.
Define relevant
network terminology
2.
Describe the function
of the 7 layer OSI Reference Model
3.
Explain the
relationship of TCP/IP within the 7 OSI Model
4.
List 3 key points
about the TCP/IP
5.
Define basic hardware
for Internet connections
6.
Explain the difference
between a standard and protocol
1. Network Definitions Crossword Puzzles
2.
