Summary of Multimedia in Web Application Performance and Security

Multimedia is day by day gaining much of the popularity on the web with some of the technologies which are being used to support videos, audios, and animation for the supplementation of the traditional media of images as well as texts. All these new media is providing different new design options but along with this they also require design discipline. For the results into the user interfaces that can do the unimpeded use of the multimedia confuse the users at a time and above all can make it much harder for all of them to understand about the information which has been used. Now every web page doesn’t need to barrage the user with the help of equivalent of the Time Square in movement and impressions as well [1].

Animation of Multimedia in Web Application Performance and Security

Animated images are in a moving state and all of them have an overpowering effect on the peripheral vision of human beings. These days it is a hard thing to concentrate on the thing, image or text which is in the moving state. It becomes difficult to focus vision on it so try not to use the moving images or texts while giving a presentation through multimedia as it can divert the attention of the listeners from what speaker is speaking and trying to convey the message. The animation is good but only in:

For the showing of continuity in different transitions

For the multiplexing of the display

For the enrichment of different graphical representations

For giving information about the image which is 3D in structure

Sometimes for attracting the listeners so that they don’t get bored while listening to the presentation for a long time.

Video of Multimedia in Web Application Performance and Security

Use of video should be reduced on the web. No doubt, videos will be used in a wide variety in coming days but for those days in future, the time duration of the videos will be short and it will only contain small viewing areas [1]. Video can be used on the web for a number of reasons which are:

For the showing of the things that move for example adding of a small clip from a ballet.

For the promotion of different shows, movies or clips which can be used for advertising.

To give an impression about the speaker to the listeners.

A very big and major problem with the attaching of videos with the multimedia is that they are not good enough in the quality. The videos are too much low in the quality. People sometimes don’t understand the words which are being used in the videos as everyone has its own reading capacity, therefore, the text is much better rather than attaching videos.

Audio of Multimedia in Web Application Performance and Security

Audio can be used in the multimedia to provide a sense of mood or place. Voice recordings can also be used instead of video to provide a sense about the personality of a speaker. Benefits of adding audio are that files are smaller than the videos, they are being produced easily and above all sound leaves a good impression on the listeners. Good quality of sound should be used, which includes a high frequency of pitch so that listeners can easily understand. It should be clear enough.

Summary of web application performance and security

For any of the application to be effective, users interfaces for sure need to comply with all of the standards. Usability testing plays a very vital role with all of the applications which are designed to make all the manual tasks easy [2].

Some of the guidelines should be kept in mind while undertaking the usability tests:

Make sure to have a sitemap

Try not to use the overcrowded content.

Ensure all the proper navigation between different web pages

User acceptance test should be done. The main reason behind using this test is to make this thing sure that all of the application meets the required expectations of the user. It also ensures another thing which is that whether the application is fit enough to be used or not [2]. There are some of the tips which can be used by the users for the testing of acceptance:

One thing should be to make sure that the mandatory fields should be provided data in forms.

Check out for the field widths.

Proper control should be used to feed the data for example while you are requesting the option of gender try to go for an option button.

Two type of testing are being used for acceptance:

Alpha testing which is being done by the developers

Beta testing which is being done by the end users

Then another kind of testing comes which is performance testing, which measures different performance in different scenarios. This test includes:

Stress testing for the determination of maximum performance limits of a certain application.

Load testing is being done to have an idea that how the application performs while having a heavy load on it. This testing gives information about the usage of memory, storage of CPU and many more things.

Scalability testing is the last kind of testing which tells about the adaptability of the application that how it changes in hardware and software.

Security testing is considered to be very important in the case if data gets leaked or modifications become unacceptable. It also ensures that the authentication, as well as authentication, are in their place [3]. This testing can be of two kinds which include:
