Web browser is a software program put to use in order to view HTML documents. It is a software application where it can obtain, retrieve and fetch various information from the Webpage or World Wide Web. Mobile web is done by using various mobiles such as cell phones, smart phones and PDA to use the web services such as i-mode (Japan), World Wide Web and WAP. Mobile web browser is the usage of mobiles, hand phones or hand sets such as PDA and smart mobiles to browse or surf the internet. The users can use wireless internet browse (WIB) to surf the internet. It is also called as micro browser. There are various ranges of smart phones available in the market such as Blackberry, iPhone 3G and 3Gs and HP smart phones.

Mobile web browser differs greatly in various features of the operating system. Mostly, best mobile web browser is where it can zoom in or out, open numerous webpage at a time or uses keyboard shortcuts, whereas normal mobile devices can only perform normal tasks or functions such as displaying the website only.


There are many limitations found when we are using mobiles to browse the web. Firstly, mobile has small screens. The users might find it very inconvenient as the small screens will cause them to have difficulties in viewing the whole webpage, or text and graphics that is found on the screen. It is much more difficult compared with the computers. Besides, smaller screens take longer time to open, close or even clicking a webpage.

Secondly, mobile web browser cannot view certain web pages, as it is not supported. There are lack of java script and cookies, causing the webpage to be jammed, hanged or, cannot be opened. For example, videos, Flash, plug-ins and PDF will cause the webpage not be able to open as there are lack of java script and cookies.

In addition, web browsing through mobiles will experience slow internet connection. People misuse mobiles to browse webpage and for entertaining purposes, instead of communication purposes.

Besides, battery life will be shorter as people use mobiles to browse web pages. As the mobile receives and sends out information, the battery life of the mobile will decrease rapidly. The more the user uses mobile web, the faster the battery life decreases.

Moreover, mobile web browsing is different compared to PCs being used at home. For example, Facebook browsing through mobiles and Facebook browsing through PCs. Through mobiles, Facebook are more likely to be in smaller screens. Besides, users cannot play games or any applications through mobiles. It is also very inconvenient for users to browse through mobiles. The information being posted in mobile is incomplete, compared to users browsing through the PCs. They have to scroll several times in order to view the whole page.

Another example of limitations is Youtube mobiles compared with PCs. The videos being viewed or uploaded in the mobiles are not as clear as compared to PCs. The graphics are not that good compared to the PCs. Besides, loading of Youtube video through mobiles takes longer time and it also causes it to lag. It takes longer time to search for the wanted video.

Next, the graphics are also one of the limitations. Graphics being posted or used in the mobile are more simplified. Mobiles use simple graphics, whereas PCs use more complicated graphics. The graphics in PCs are nicer and have clearer image.
