Connection speed can a big different between how fast and slow you can set up your website if your using a wireless connection and are setting up and making a website up in the same room without blockage of walls then setting up and creating the website will work fine for the user.

Server side

Internet traffic can be a big impact on speed performance as a lot of people are trying to get information on a website which you are trying to get onto it will take a long time for the webpage to load for you and other users which will make people not want to wait for the information to load up which effects the website speed

Bandwidth is what determines how much the user can download through their ISP for example it depends on the file size and some ISP provide a variety different speeds for users to use on the Internet. It is usually measured over a length of time such as seconds. A higher bandwidth basically means that the user can download more files with a certain period of time. If someone has a high speed internet but does not have a good bandwidth they still won't be able to download that because they are restricted and downloading files will work slowly

Cache is Random Access Memory that a CPU can access quicker than it would with a regular RAM, the CPU will then use cache memory to store instructions that are required to run programs. You will find a larger cache will operate at a specific high speed and is the core of the CPU

Explain three security mechanisms that can be used to help prevent the security risks and improve website performance. (P3)


Explain how viruses can effect the web server

Viruses can affect websites by making them slower for users and for the host of the website. Users can use virus to hack website details and cause problems with the server by sending traffic to the website which will make the website slower for other users to trying to access the website

Explain how can this be protected

Explain how can this be protected

An anti virus can protect you from key loggers and virus that hackers can use to get access to a web server. Another way to stay protected by hackers I the have secure payment on the web server so that nobody can get the details or think it's unsafe to make a payment

Identity Theft

Explain Identity Theft can effect the web server - Identity effects a web server because users on the Internet can hack personal information about the company, Not just the company but the user of the company too such has bank details and emails and addresses etc and they will use the identity for them self

Explain how can this be protected -ie strong password

They're many ways to be protected by Identity theft. One way to be protected from Identity theft is having an Anti Virus which can detect virus and hackers trying to get into the server. Another way is to have a strong password for example using a mixture of higher case and lower case letters and using numbers so that it makes it hard for the hacker to get into your personal details

Domain Name

A domain name is a name which gives it to a website so it can connect to computers IP. It is a set of numbers which gives a website a code but the website name for example is a more simple name to be used for people to search for the website

TCP stands for Transmission Control Protocol which is a variety of packets which goes through ports to make a connection to another computers IP address

Web Host

People who set up a server for you to access the world wide web and find out information on the Internet


HTTP stands for Hypertext Transfer or transport protocol is an application that helps that helps users to allow them to show information on a web page. HTTP is the most commonly used way that users use for browsers to communicate.
