HTML
Hyper Text Markup Language was created by a British computer
scientist called Tim Berners Lee in the early 1990’s. It’s
original use to help researchers share and refer to electronic
pieces of information (simple links).
Programmes to read and interpret HTML were written, called web
browsers and programmes to serve them up called web servers.
Although there has been advancements (HTML 5), HTML is the
founding programming language of the Internet.

image can be used legally and which can’t.
EXT: Include actions you could take to comply with copyright
regulations.
DISCUSSION: What factors would you need to consider if you made

Going Live
If you wanted to publish your webpage on the internet what
software and services would you need?
TASK: Research, list and explain.
• Domain Name Registration – to register your domain or URL
• ISP/Web Host – provide the web server to hold your webpage
(s) so they can be viewed anywhere in the world.
• FTP Software (File Transfer Protocol) - to up load the
images to the web host
Think of a good domain name for your site and see if it is
registered yet from a service like this

Some
interesting developments

DNS Servers
This stands for Domain Name System.
DNS Servers:
• Have a database of IP addresses
• Are constantly updated by other DNS servers
• When a web address is requested the DNS looks up the URL and
returns the IP address, or searches for the addresses from
other DNS servers
How the DNS works
• What are the advantages?
• People do not need to remember IP addresses
• IP addresses are easily upgradeable without the for web
addresses to change
• You can have access to all IP address via DNS servers
