The Internet is far more than just the World Wide Web. The Web was created in 1989 and became popular in the 1990s. In contrast, the Internet is a product of the1960s. The Internet is a vast network of networks that electronically connects millions of people worldwide. It was formed in 1968, when the U.S. Department of Defense’s Advanced Research Projects Agency (ARPA) funded what would become the first global computer network, the Advanced Research Projects Agency Network (ARPANET). ARPA later became the Defense Advanced Research Projects Agency (DARPA). The ARPANET allowed university and government engineers to research and work from any location on the network. ARPANET’s design featured multiple hosts and multiple connections among those hosts, which greatly reduced the chances of total network failure. There was no central hub, which would have created a point of vulnerability; rather, control was spread throughout the network. This decentralization resulted in a robust and reliable network that would continue to function even if some of the hosts were incapacitated.
In 1989, the Department of Defense decommissioned the ARPANET, and all the sites switched over to the National Science Foundation (NSF) network, called NSFnet. The NSF increased the number of supercomputers to five and added access to more networks, expanding the range of sites for businesses, universities, and government and military installations. The NSFnet, plus thousands of others, compose what has become the largest network of networks: the Internet.
The World Wide Web if the most important concept to remember is that the Web is not a network itself, like the Internet, but a set of software programs. These programs can be used on many different computer networks, including the Internet and your company’s computer network, the Web presents information through multimedia formats: graphics, sound, animation, and video. It employs several tools to provide a visual layout: hypertext links, browser software, and code structure.
As we see in this brief overview for the evolution of the internet and the web, we notice that the web was first design to just provide information that could be accessed from desktop computers, in the early days of the web there was no mobile devices and there was no need to access it from such devices, but now a days when the mobile technology run very fast and when mobile become an important part of our daily life here accessing the Internet from mobile devices is becoming increasingly popular. Web access from mobile devices presents its own unique challenges, Mobile web users face a big problem that the majority of web content is tailored for desktop computers; there were many trials to solve this problem. The principal objective is to improve the user experience of the web when accessed from such devices.
Researchers try to find solution to make mobile web users able to run the web from their devices but they face many problem and they have to solve them, there was many problems that is related to the hard ware of the mobile devices like small display area, lower processor memory and many other limitations that we will discuss, and there is also some software problems like each mobile device run its own operating system and its web browser also, here in this thesis we will focus on the problem of different screen size and how can we adopt the web site to match this verity of screens.
There was much researches that was done in this area, some of them focus on how can we have two versions of each web site one for the desktop users and other for a mobile users and how the mobile version should be, some others focus on create only one version and have a small module that re-author the original web to have a new version that could match the mobile users, also there was some peoples say that we don’t have to make another version to match mobile we can run the desktop version if we don’t have much users for this web site.
