Unique Resource Locators (URLs)
Unique Resource Locators (AKA Web Address)
An URL (aka web address) is the alpha-numerical address that humans type in to a web browser to access a website. Humans like to use URLs rather than IP Addresses because they are easy to remember.
An URL can be the name of a website or a specific page and may also contain query parameters / port numbers.
- Website Address – https://www.google.com
- Webpage Address- https://learnlearn.uk/alevelcs/
- Webpage address with search query – https://learnlearn.uk/alevelcs/?s=internet
How DNS Works
Domain Name Service
The internet works using IP Addresses, so all URLs must be translated(resolved) into and IP address.
This is the job performed by the Domain Name Service. Domain name services are usually hosted on servers.
