Unit 28: Website ProductionWhat are your instant thoughts

and feelings?We will capture them on a

mindmap


Objectives• Understand the fundamentals of

Web Architecture• Explain web jargon clearly


Before we get any further…1. The Internet ≠ the Web– The Internet is the network

connections– The Web is one use of the internet –

for loading web pages

2. You can’t understand the Web without understanding the Internet


How does the Internet work?Key Words:• Client• Server• Network• Connection• IP Address• Domain name

• Data• Packet• Router


So how does a website work?(this is a server)

When you want to see a webpage your computer sends a message over the internet asking for that page

The web server finds the page on its hard drive and sends it back as a new message

Meanwhile, lots of other users are asking for that page and many others too


Anatomy of a Domain Namewww.amazon.co.uk

www.birmingham.gov.uk

This means that it’s a site based in the UK

This tells you what kind of site it is

This is the domain name – usually the name of the organisation

This means that it’s a web server

Other TLDs (often country codes):.com .ie .es .br .org .nz .de .tv

Other types of servers:FTP mail pop3It can also be a subdomain – a special extra website


Getting a Domain Name• All computers on the internet get an

IP address but not a domain name – you have to pay for that!• You pay the “domain registrar” who

is allowed to sell domain names by the organisation that runs that TLD• Different costs based on popularity

of name and TLD


Who looks after the server?• First of all, it’s not really a special

computer other than the software it’s running• But most normal people don’t keep

them at home!• Why not?


Web Hosting• This is when you pay a company to look

after the web server that your website ‘lives on’• Research: find 3 different companies

that provide web hosting (UK based, please!)• Compare the services they offer• Store this information in a table – you’ll

need it later today for the assignment!

Assignment 1The purpose of this assignment is to: give students the opportunity to show a knowledge of the basic features of web architectureAssessing: P1

outline the web architecture and components which enable internet and web functionality


ScenarioYou work as a trainee for YellowZebra, a new Web Design company based in South Birmingham. They specialise in online marketing consultancy and in designing, implementing and hosting e-commerce websites for small to medium sized local businesses.Your manager has asked you to create some information to show prospective clients, presented as Powerpoint slideshows, leaflets and reports. You have also been asked to design and create a website to show your creativity and technical skills.


Tasks (There are 2 for P1!)Before a client website can ‘go live’ it will need both a domain name and to be hosted. Create a presentation to show new clients:• Explain the purpose of a hosting service and the

typical functions provided.• Look at three different website hosting companies

and identify the services each offers.• Using a domain diagram, explain the structure of a

domain name.• Explain the role of a domain name registrar and find

out the registrar of a chosen domain name.


Note (see the Scenario)Presentations should be ready to present and may include speaker notes and timed transitions.


Task 2In response to customer feedback after introduction meetings, it has been found that some key words or jargon sometimes need explaining. Add extra slides to the end of your presentation to explain the following terms:

• World Wide Web• HTML (HyperText

Markup Language)• Web Server• ISP (Internet Service

Provider)• Domain Name Server

(DNS)• Router• Proxy server• Mail server• Browser• Email software


Deadline (& Homework!)• I expect this to be handed in to me

before the beginning of my next lesson with you – next Thursday• Email your work to me – make sure

it’s finished and perfect so you don’t have to re-do and waste time that should be spent on other work!
