Server side factors

The web server capacity can affect the speed of downloads. For example if the file has a small scale then the download speed will be poor. This is also the same with bandwidth; if you wanted to create a website from home it would take longer to download than other websites such as Facebook or Tumblr because it has a smaller bandwidth. Sound and videos take longer to load too, files such as GIF and JPEG are the only files that work effectively. To increase the download of a picture for example, you must decrease the scale of it which then allows it to load faster. Files such as MP3 you need a QuickTime plug in and in order for SWF to work it requires the plug in flash.

User side factors

There are certain factors that affect the functionality of a website. The user side factors are PC performance, cache memory and speed.

PC performance – you need an up to date processor to enable you accessing certain programmes or websites. The PC performance can slow down or even stop the processor from running certain programmes or websites.

Cache memory – How full the processor is will affect the functionality, things such as saving passwords to the computer or saving things in your basket on certain websites can slow down the computer. Because of this the processor may have to reset to improve its download speed.

Speed – The traffic of the programme can affect this, for example if popular tickets were being sold on Ticket master and many people were on the website it would be very slow loading and may even tend to buffer and freeze regularly due to lots of people trying to access the website at the same time.
