Unit 8.3_Lesson 1_CD Resource 1a_URLs presentation

• URL is another way of saying ‘web address’.• There are at least 3.5 billion websites in

existence.• Although there are billions of websites, each one

has a unique URL.

URL - Uniform Resource Locator




Hypertext Transfer Protocol

• http:// appears at the beginning of all URLS.• Hypertext Transfer Protocol is the set of rules

which enables a computer to read a web page. • Sometimes it contains an ‘s’ – https:// The ‘s’

stands for secure. You should always look for this when paying for goods online.



• www stands for ‘World Wide Web’. All websites used to include this, but nowadays some companies choose not to.

www – World Wide Web



• The next part of a URL is the website’s domain name.

• Domain names have to be bought. Once a person or organisation has bought a domain name, no one else can use it because each URL has to be unique (meaning the only one!).


Domain name


• The letters immediately after the company name show the domain type. This can give us information about who made or owns the website.

Domain type




Example of Domain Types

Domain Type

.com Company, could be anywhere in the world. US companies use this.

.co Non-US company

.sch School

.gov Government

.edu University

.ac University or other academic institution, such as museums, art galleries etc.

.org Organisation – charities and non-profit organisations often use this

.net Network – but used very generally

.me Personal

• We can usually tell where a website originates from these two letters.

.br Brazil.fr France.de Germany (Deutschland).ie Ireland.es Spain (España)

Country type

Country Code

USA has no country code

.uk United Kingdom

.au Australia

.dl Deutschland (Germany)

.nz New Zealand

.fr France

qa Qatar

.es Spain


Path to file or resource

• Everything that comes after the country type refers to the page within the website that the URL is pointing at.

• In the example above, the path is /kids. This means that this URL is for the page on the paintball games website which contains information for kids.

• The path is normally separated from the site’s domain name with a / (forward slash).

Distinguish between fact and opinion

A Fact is an information which can be scientifically proven.

example: Islam has the most followers of all the religions in the world

An opinion is the way somebody feels

example: England is a great place to live.


Identify reliability and bias

Reliable: How much do you trust the information? You should consider

what you know about the author or organisation who owns the site (the

URL can help with this). Is the site official, personal or a company site that

is trying to sell you something?

Bias:

Does the site contain a lot of opinions? Does the site only give one side of

an argument? If so, it is probably biased and you will need to find other

sites to balance the argument.
