NETWORKINGNetworking is a Department under the School of Computer Science. Courses focus on the interconnection of computing systems to share resources, and ultimately should provide an ever-increasing level of complexity in subject material, much as advancing classes in a traditional university do. Networking is the practice of enabling and harnessing the transmission of data from one computer system to another. A crude analogy of a data network is pictured at right: two tin cans connected by a simple string. Note that what this basic analogy suggests holds true for actual implementations of data networks: - The network exists merely as a medium for communications of some kind, across it
- A protocol of some form is needed to initiate and carry on conversations (this is not intrinsic to the network itself)
- The same protocol (a spoken language) can also be used with different media for the same purpose; different networks have different advantages and uses
A network may require one engineer to design it, another engineer to build it, and another engineer entirely to administer it. The skills needed for each stage in the process are related but not necessarily dependent; hence, Networking is interdisciplinary. The distinction between Networking and Computer Science in general is difficult to precisely define; it is better perhaps to consider that Networking grew out of Computer Science, because of a need to extend the existing capabilities of a computer (which includes data transmission) across large distances and with other unlike systems. However, an extensive background in Computer Science is not necessary to study or even practice Networking. A Network Engineer is a qualified individual who works with networks of some form, but the scope of that work and the skills required may be as diverse - even from one job to the next - as those of any scientist. Networking is the practice of enabling and harnessing the transmission of data from one computer system to another, and can be divided into three categories: - Connectivity Concepts - The principles and methods devices use to communicate over a network
- Mediums - The actual, physical method used to communicate.
- Administration - The process of maintaining a network.
| SUGGESTED COURSE PROGRESSIONRequired- Introduction to the Internet
Obviously there wouldn't be many web pages without the Internet. But what is it? What is is the difference between DNS, TCP/IP, HTTP, a web server and all the other stuff that makes up this super highway? - Using HTML and CSS
The building blocks of every web page are the HyperText Markup Language (HTML) and Cascading Style Sheets (CSS). Basically, when all is said and done, 90% of what a user actually sees is comprised of these two items.
OptionalProgramming LanguagesChoose one (or more) language(s) from the following. These languages are the basis for enterprise applications. They are languages that are generally independent of the web and are therefore some of the most powerful languages in use today. On the other hand, their power also adds to their complexity. Study of Java, Visual Basic, C# or others can be an entire topic by themselves. - Java - Java, in and of itself is not a web specific language. It is a powerful standalone language capable of creating Desktop applications, Browser based applications (Applets), or full web server applications. Web development concentrates on applets and full web server applications.
- Java Applets
- Java Server Pages
- optional: Enterprise Java Beans
- .Net Language - Microsoft's latest web development environment is focused around its .net framework. There are several languages used to develop web server based applications.
Choose one (or more) language(s) from the following. On the lighter side, these languages are more closely related to web development. While they can be just as complete as the languages listed above, they tend to have a more "web development feel."

| WEB 2.0webmailWeb-based or webmail is email that is accessed through the web and stays on the web. The main benefit is that the user can access their mail at any location with a computer that has a internet connection. The first webmail service was Hotmail and is still one of the most popular.Discussion boardsreplacing newsgroups, a discussion board is an online bulletin board where you can read and leave messages for the public or members of that site. The first discussion boards were available on bulletin board systems.IMInstant Messaging - Anyone on a given e-mail system can send a message and have it pop up instantly on the screen of anyone else logged onto that system. examples of instant messaging systems are AOL, MSN and Yahoo
PROS: allows a faster way of communication than email, and can reduce long distance bills CONS: lack of privacy, many IM products don't communicate with another, and can destroy concentration when working.BlogA blog (short for weblog) is a personal online journal that is frequently updated and intended for general public consumption. Blogs are defined by their format: a series of entries posted to a single page in reverse-chronological order.Blogs generally represent the personality of the author or reflect the purpose of the Web site that hosts the blog. Topics sometimes include brief philosophical musings, commentary on Internet and other social issues, and links to other sites the author favors, especially those that support a point being made on a post.
Before blogging became popular, digital communities took many forms, including Usenet, commercial online services such as GEnie, BiX and the early CompuServe, e-mail lists and Bulletin Board Systems (BBS).VoIPVoice Over Internet Protocol is a type of internet telephony in which the net is used to make phone calls, either one on one or for audio-conferencing. You can make long distance phone calls that are surprisingly cheap or even free.
Skype is one of the most popular program that use VoIP, and is currently expanding into the wireless cellular division. The expansion of the WiMax network will dramatically change the current market of cellular technology.WebcastWebcasting is where customized text, video, and audio samples are sent to you automatically on a regular basis. You choose the categories or channels of websites that will automatically send you updated information. It saves time because you don't have to search for the information.
