Presents a survey of computer network elements. Course focuses on low-level and applied concepts and issues. Local area networks are emphasized; internetworking issues such as routing are also covered. Hands-on activities include: packet sniffing and "wire-level" network traffic, constructing an Ethernet cable, and configuring a LAN
At the end of the course students will be able to:
1. Describe the basic function of each layer of the OSI model.
2. Identify and describe the major protocols at each layer of the TCP/IP protocol stack.
3. Identify the hardware components in a Local Area Network (LAN).
4. Characterize the performance of various network cabling options.
5. Construct and use an Ethernet cable.
6. Use a protocol analyzer such as Wireshark to inspect traffic on a LAN.
7. Construct subnet masks for IPv4 network addresses.
8. Describe how routing works in the IPv4 Internet.
