WDD - Notes
ISP - Internet Service Providers
- use a technology known as deep packet inspection in order to regulate network congestion (network traffic) and lessen Internet bottlenecks.
- Example of ISP - Telbru
Website Hosting
- A web hosting service is a type of Internet hosting service that allows individuals and organizations to make their website accessible via the World Wide Web.
- Web host are companies that provide space on a server owned or leased for use by clients, as well as providing Internet connectivity, typically in a data center.
- Example of Website Hosting - bluehost.com
Website Management
- A Web Content Management System (WCMS) is a software system that provides website authoring, collaboration, and administration tools designed to allow users with little knowledge of web programming languages or markup languages to create and manage website content with relative ease.
Example of WCMS: -
- Joomla
- Typo3
- Wordpress

How does the Internet work?
Internet - Interconnected Network
Investigating relationships between
- domain names, DNS services and communication protocols used to access a website.
IP address vs Domain Names
- Domain name is the name of the website, and IP address is the address of the website.
DNS service us a service that runs Domain Name System servers. Include DNS hosting service with registration
Hosting is where the websites are registered.
Protocols
The Internet Protocol (IP) is the principal communications protocol in the Internet protocol suite for relaying datagrams across network boundaries. Its routing function enables networking, and essentially establishes the Internet.
IP has the task of delivering packets from the source host to the destination host solely based on the IP addresses in the packet headers.
TCP / IP - has 4 layers.
1. Application - represents data to the user and controls dialogue.
2. Transport - Supports communication between diverse devices across diverse networks.
3. Internet - Determines the best path through the network
4. Network Access - Controls the hardware devices and media that make up the network.
DNS Servers
DNS servers has a domain name and server.
it provides hosting.
No DNS server contains the entire database; they only contain a subset of it.
What are secure sites?
- Generally, secure websites use encryption and authentication standards to protect the confidentiality of web transactions. - Provide password
- SSL
Publish Secure sites
2 ways: -
1. use web publishing (online/ subscribe to website hosting)
2. use web server (offline/ hardware)
Managing a secure website
1. Keep the software up to date
2. Block SQL injection
3. Prevent XSS
4. Providing minimal error messages
5. server side validation/form validation
6. passwords
7. denying file uploads
8. HTTPS
