	NETWORKING Networking 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. Topic: WEB DEVELOPMENT Web Development as opposed to Web Design is the process of creating websites with functionality above and beyond displaying static content. While Web Design is concerned with the layout, look, feel and aesthetics of a website, Web Development is concerned with how the content is delivered, where it is stored, who can edit it, and what viewers can do with it. What you can learn here The following topics have been ordered to help provide a pathway for you to learn the main skills of web development. Optional Prerequisites Install a Web Server - If you are going to have a web site you have to have a way to serve the pages. This lesson shows you how to get a basic web server running. Getting Started Web Design/Getting Your Site On the Web - So you've got your site, now you need to get it on the web for everyone to see! Select and Install a Content Management System - Do you want to upload your HTML files to your site every time you make a change or do you want to edit your site through the site itself? Do you want to have users and security? Do you need extra functionality? A Content Management System sets the stage for your website. Using the Right Tools - See a growing list of selecting the right tools for the job! Web Development Web Application Frameworks - Before we start extending the web, lets look at how it works. Security - "Security is hard." Jim Fulton, chief Zope architect. Web Languages - ASP.Net, Java, PHP, Python, Ruby. All you need is one language to create the next greatest thing. Now, which one.... Data Persistence - In addition to having the programming skills, you also need to do something with all that data. How and where you store it can have a significant impact on your system.
