Students

For the last 8 years I have been lecturing to community college students at the H. Lavity Stoutt Community College. Although my area of expertise is databases and web design, I also lecture in the areas of computer networking and Java programming.

This area of my website is dedicated to my students. From here they can view and print handouts from classes that they may have missed or lost the handouts to. There is also an area where I publish papers that I write from time on issues pertinent to the field and of use to students.

 

Handout 9 - Subnetting

Subnetting

A subnet is a physical segment of a TCP/IP network that uses IP addresses derived from a single Network ID. Large networks are typically divided into several subnets for ease of management and sometimes because of physical limitations. Each segment of the network, or subnet, would use a different Network ID or Subnet ID.

Handout 8 - The TCP/IP Protocol Suite

The TCP/IP Protocol Suite

The TCP/IP suite was developed by the Department of Defence (DOD) before the OSI Model, and consequently it does not map directly onto the OSI Model. However, it does map closely to the layers of the OSI Model.
