- It is made up of numerous WANs
- It is based around TCP / IP
- The WWW is a collection of websites accessed through HTTP
- URLs are addresses used to access web servers and resources on them
- A Domain Name Server (DNS) translates a website's domain name into its IP address
- The cloud
- Hosting is when a business uses its servers to store files of another organisation
- The cloud is now the general storage of user files
- Acts like an extension of the client-server network
- Pros
- Users can access files any connected device
- Easy to increase how much storage is available
- No need to pay IT staff to manage the hardware
- Cons
- Need for connection to the internet
- Dependent on host for security and back-ups
- Unclear who has ownership over cloud data
- Virtual networks
- A VN is entirely software-based
- Created by separating bandwidth to form a separate network
- Several VNs can exist on one physical network
- Each VN has its own security and firewall
- VNs can only be accessed by using certain software or login information
- Virtual Private Network (VPN) is a type of VN that can be used to send data securely
- A virtual LAN allows you to split s LAN into several networks
