Explain the user side and server side factors that influence the performance of a website

There is many factors that can influence the performance of a website some of the main factor are: Hard drive data speed, bandwidth, ram memory, and CPU processor speed are all factors that influence website performance on the user side and server side.

USER SIDE Connection speed - How quick the website loads on the user’s computer depends upon what type of network connection they have. The use of Broadband connection is a lot faster than that of a dial-up connection, which can be proven in the table below. A slower connection means it takes a lot longer for the user to view and browse the website.

SERVER SIDE Internet traffic - Traffic on the web server results to the user not being able to access a website as quickly as they should. If the users worldwide were to type in the same web address at approximately the same time, the web server may have a lot of demands, causing it to take longer to upload, as there is a high number of people wanting to access the site. In some cases the web server may not be able to keep up with the demand, so they state "this page cannot be displayed". Hardware- is quiet important or can Hardware- that's set up "behind the also affect the speed of a website. It is scenes" can't handle the load of important that you should have the several hundred users per minute or right components. even second, and then the site may For example the processor can have either load slowly, or not at all. an impact on how fast a website loads and if you upload something to a web the time will be depends on how good your processor.

Browsers – Can affect the speed of the internet. If you delete the browsers history in every 1 week the internet can get fast.

Maintains- It is important to the server owners to maintain their servers correctly and they also have to make sure it is has appropriate security software’s protecting it. If they don’t maintain their servers correctly or don’t have correct software’s protecting it then the website can slows down or even crash. Malware- Short for malicious software Malware- Like the user side the server is software designed to secretly access side can be affected too by malwares. a computer system without the Like there is chance that your website owner’s permission.

Bandwidth-

Software- plays quite important role with the servers. Such as protecting it from viruses and other threats. Servers also use certain software’s so it will be easy to maintain.

File type and size- The website owner Software- can affect the performances whom created their site may have a of a website. Internet security fast running computer network, so software’s can affect the performance therefore choose to have large files on some security software’s their website. However for some users automatically blocks some sites while this could be seen as a negative some can slows down and some runs affective in relation to the websites scanners before or after they performance, as those with slower download certain files. networks may have to wait a long time, before all the website uploads. This can be very annoying and time wasting for the users.

Number of net applications runningcan actually slows down the net speed for example if you are downloading something at the same time if you open the website it will be very slow. Viruses- can affect the normal operation of a computer. It can slow down the Internet connection or make the computer processor think to hard which results it to be busy processing. This is hugely problematic when referring to the performance of an affective website, as it implies the user would not be able to access the website quickly.

The speed and size of their Web servers. What type of hardware is your site being served from? The more CPU power dedicated to handling server requests, the better.

Explain the potential security risks facing websites and the protection mechanisms involved in website performance. Because the internet is unregulated, unmanaged and uncontrolled, it poses a wide range of risks and threats to the systems operating on it. The use of the internet means that your internal IT and server systems are potentially accessible by anyone

There are lots of components and software’s which affects the performance of a website Some of the main threats are viruses Viruses, Trojan horses, worms are all computer programs that can infect computers. Viruses and worms spread across computer and networks by making copies of themselves, usually without the knowledge of the computers owner. Trojans is similar ways to normal viruses but it gets it to a computer through a program. You can use ant viruses to protect your computer from threats Some other problems are Firewalls Always make sure firewalls are on when accessing internet and it’s up to date. Port blocking If you don’t need a particular port then make sure you closed it or others can get to your computer, Browsers can also affect how fast each websites load in some browsers some websites might load slowly or some even shows if the website is threat or not. Passwords Make sure you use strong password a strong passwords should include a number, symbols and letters

Hackers and identity theft are big threat to computer users who uses internet to do shopping and who saves their personal details on their pc’s Uses the internet as a means of gaining access to your computer from another location. Indeed it may be that the person or persons hacking into your computer are not even on the same continent. Now that Internet Service Providers (ISPs) are offering always on internet which means that the internet is connected if your computer is switched on or not - there is more chance that your computer could be subject to hacking while you are away from it.

You can protect your computer by setting up strong passwords always up dating anti virus’s software’s also close all the unwanted ports. Some of the common threats are:
