Define internet.
It is a concept that connects many networks and relies on physical infrastructure.

List the advantages of adopting intranets rather than internet.
- safer (less chance of hacking or virus)
- specific info available

Differences between internet and intranet.
- Internet- International network
- Intranet- Internal restricted access network
- Internet is public, Intranet is private
- Anyone with and ISP account can use internet, intranet can only be used at certain access points and systems.
- Intranet gives only relevant info but internet has info on a huge range of topics
- It is easier to block certain sites on intranet than internet
- Intranet needs pswds and IDs
- Intranet is behind a firewall which is safer.
What is cloud storage?
It is a method of data storage where data is stored on offsite servers. The physical storage covers hundreds of servers all over the world so data can be accessed anywhere.
What is data redundancy?
Data in clouds is stored on more than one server so that clients can access data at all times even during maintenance and repair.
Types of cloud storage.
- Public cloud- customer and cloud storage provider are different companies
- Private cloud- Storage provided behind a firewall. Customer and cloud storage provider are one unit
- Hybrid cloud- Combination of private and public.
Advantages of storing data on a cloud instead of other devices.
- Files can be accessed anytime, on any device, anywhere provided the user has internet access
- No need to carry around storage devices and use only specific devices
- Provides backing up and recovery of data
- Offers almost unlimited storage
Disadvantages of storing data on a cloud instead of other devices.
- If internet connection is slow, accessing files could be hard
- Costs can be high if lots of storage is needed
- Failure of cloud storage can cause permanent loss of even backup data.
Define HTTP and HTTPS.
Hypertext transfer protocol (secure).
Set of rules that must be obeyed when transferring info and data over the internet. Slower to use https because it has encryption.
Web browser
