Passing Data - Coursework Example

INFORMATION TECHNOLOGY al Affiliation) Question There are various reasons why data may be passed from a string; the first reason emanates from the fact that passing data from a string allows one to pass data from one page to another. This is usually performed using query strings. Additionally, this method allows for setting up structures like JavaScript that basically facilitate the retrieval of query strings. This method is also believed to be simpler as compared to other methods of data transfer.

One method used to hide data in a form is through the use of HTML; this entails the use of a “METHOD-GET” attribute characterized by the encoding of information. Question 2 Cookies are usually associated with four main vulnerabilities; the first one is ‘cross-site cooking’. This entails the existence of browser flows that create loopholes for malicious attacks. Another vulnerability associated with cookies is cookie inaccuracies; these are instances where cookies may indicate inaccurate data.

In addition, there is the vulnerability of cookie poisoning. This occurs when web attackers modify the content of cookies before re-sending to the server. Consequently, cookies are usually ascribed to cookie theft where: Cookies sent through ordinary HTTP are accessible to anyone. However, these vulnerabilities can be reduced through web vulnerability detection code review. Question 3 One of the Document Object Models that can be used to make web pages dynamic is the use of JavaScript. This can be used in combination with W3C and may entail the use of array objects, number object, math object, date object et cetera.

Moreover, HTML DOM is another method used to create dynamic web pages it entails the use of objects such as HTML elements, HTML documents, HTML attributes et cetera. There is also the use of Browser objects that usually entails the use of window objects, screen objects, history as well as location objectives. Question 4Image caching is an aspect of ICT that has not been applied in many web development processes; however, computer experts have asserted that this is an imperative aspect of web design that ought to be taken into consideration.

Image caching is basically a duplication of the original data for ease of retrieval. Image cache facilitates increasing the speed with, which a web functions. Lack of implementing of the use of an image cache basically reduces the speed of one’s computer usage.
