The Internet

The Internet was a new concept that was developed initially for the sharing by universities in the United States of America. Computers joined through a worldwide network by cabling, either optic or copper wire, and microwave. Initially the speed of the network was quite slow, however, fast Broadband is now available and is the norm.

The Internet is a structure that enables access to the World Wide Web. This means the hardware, the topology and all the technical components that help it to work.

The Internet has now provided the user with the ability to carry out the following range of activities below are a list of nine that will be studied:

  1. obtaining news
  2. sharing of files
  3. video conferences
  4. chatting
  5. emailing
  6. researching
  7. self-publishing
  8. online commerce
  9. obtaining technical services and products

  2. Justify the choice of the two most important events in a sentence for each of these.
  3. Add three more recent developments to the Internet .

Intranet

An Intranet is a logical development in the networking of a group of computers. An Intranet is basically the same as the Internet, but is private and accessed with a password. MyInternet the interface you use at school is an Intranet. You require a user name and password to authenticate with the Intranet server.

A user in an Intranet as able to complete all the tasks that are available on the Internet, such as communication with email and sharing files.

An add on to the Intranet is an Extranet, this allows users to access some information that may be available in an Intranet, but not all. The details found on the school website is an Extranet.

A detailed explanation of Intranets may be viewed on the How Stuff Works link below.

How Stuff Works explains what is an Intranet is.

World Wide Web (www)

The World Wide Web is actually the resources that are available on the Internet. These include graphics, text files and the linking hyperlink format. This WWW is an amazing medium for the dissemination of information with the addition of interactivity. Interactivity means that the users have the ability to communicate with the resource while using a computer hardware device. An example of this is through the use of a link called a Hyperlink, which when selected the user is able to view another site or page within a site.

View to see how the Internet works.

weekly homework task 1. Due week 2
Q 1. Provide the meaning of the term “intranet”.
Q 2. What is the World Wide web?
post this response in your site.

Internet software

A web browser such as Internet Explorer, Opera, Safari or Firefox is required as these applications read HTML code. Another vital component is to have an Internet Service provider or ISP. The ISP provides the user with access to an Internet connection.

Web pages use specialist software to write the code that is used to organise the data for the Internet structure.
This specialist software is known as authoring software and uses HTML as the basis of the website that is produced. HTML may be used with a simple text document and displayed in a browser. More sophisticated software is available such as FrontPage and Dreamweaver. WYSIWYG or “What You See Is What You Get” is used and an example of this is when a web developer works in Frontpage using the “Normal” mode.

Types of protocols

• transmission control protocol/internet protocol (TCP/IP)
• hypertext transfer protocol (http)
• simple mail transfer protocol (smtp)
• file transfer protocol (FTP)
• hypertext transfer protocol secure (https)

Control of access to information on the web

Originally the Internet was a small network of academic organisations and access was quite liberal, however, with the growth in the number of users and uses and importance of data and information, access has become an issue demanding attention.

Organisations are required to use a range of access controls to protect the information that is contained in data storage. Banks, Government departments and hospitals all have sensitive or confidential information that need protection.

Hackers are now creating viruses that attempt to gain access to the information not only to organisations but also to the private user. The following five terms are important to become aware of as these are all concerned with protecting your computer from inappropriate access.

• cookies-a small code that allows a site to track a users use.
• security content-are filters that ensure inappropriate web content is blocked.
• proxies-limit access and serve to cache sites.
• firewalls-limit or stop selected network traffic in and out of a network.
• virus protection-are programs created and delivered to a computer to obtain or destroy data.

Website development and Features of a website

A website usually contains a number of web pages that are linked with hyperlinks. These pages are static or can not be edited without access to the ftp site and this will also require a password to authenticate the user.

The design of the website are of a Graphical User Interface or GUI. This means that a graphic or icon with a logical meaning may be clicked on to interact with the site. An example of this would be a printer icon or email icon. This GUI layout may be in text as well, but a heavy use of graphics are used in a website.

The address of the website is also set to a standard. The address of a web page is called a universal resource locator or URL. The URL comprises of the protocol used in this case the http, then the server domain name, next comes the directory name and finally the file name.

The layout of the web page may be presented using tables which may be used to hold text and objects very easily. This then provides a clearer display of information to the reader.

Probably the most recognisable feature of a web site is the use of links (hot words, hot spots) to enable navigation or to find further information.

weekly homework task 4 . Due week 8
Q 1. What is used to link webpages?
Q 2. What is meant by the term Graphical User Interface or GUI?
Q 3. What is meant by the term URL?

HTML

Hypertext Markup Language or HTML is the basic website creation tool. The code used in HTML instructs the browser as to how the data is to be displayed. The code comprises of text and tags, the tag also control all the elements such as colour, location of objects and multimedia.

Project development

The planning, production and overall development of a project has six steps.

  • understanding the problem
  • making decisions
  • designing solutions
  • implementing the solution by testing the product
  • implementing the solution by maintaining the product
  • implementing the solution by evaluating the product

If you do not know what is required to be completed to solve a problem, then the resultant solution is very unlikely to be correct. It is therefore, important that the task be understood. this may be done by asking questions of the potential participants of a solution.

Once that you decide upon the problem, then you need to decide on a solution. Probably thinking about one design only is not the best, create a few designs so that you can decide upon the best.

Once that you have decided upon a solution you may then commence to create a solution or product that will solve the problem. Make what is known as a prototype first. a prototype is a model or limited functioning product, to see if the solution is appropriate. a storyboard is also a sound design tool to develop a product, especially a video or audio product.

Once you have decided upon the solution, then make it. evaluation of the product is a continual process and should be completed through out the design and implementation process. maintenance will also be required to be carried out as the product is used.


You must complete portfolio 1, 2, and 3. then complete portfolio 4 as the major assessment. The portfolio needs to be added into your wiki on the due dates set.
