I taught for at the community college level for many years, Questy's Webmaster's Portal, formerly at Questy.com, was used as outline for students to review material covered in the classes that I taught. 

Webmaster Site Designer is a series on  how to implement and maintain hypertext-based websites using authoring and scripting languages, use web management tools and digital media tools, and apply human factor principles to design.

Site designer skills are a combination of minimal technical and non-technical skills required by a website designer that are not product- or system specific.  While we will discuss various software packages, and use available software to illustrate concepts, the focus is the understanding of the concepts and issues rather than any particular software.

On a small to mid size network there may be little, if any, distinction between a Systems Administrator and a Network Administrator, and the tasks may all be the responsibility of a single post. As the size of the network grows, the distinction between the areas will become more well defined.

In larger organizations the administrator level technology personnel typically are not the first line of support that works with end users, but rather only work on break and fix issues that could not be resolved at the lower levels.

Network administrators are responsible for making sure computer hardware and the network infrastructure itself is maintained properly. The term network monitoring describes the use of a system that constantly monitors a computer network for slow or failing components and that notifies the network administrator in case of outages via email, pager or other alarms.

The typical Systems Administrator, or sysadmin, leans towards the software and NOS (Network Operating System) side of things. Systems Administrators install software releases, upgrades, and patches, resolve software related problems and performs system backups and recovery.
