One way that computer networks help to protect data is by backing up the data.
Computer networks are normally formatted to automatically back up all of the data that is stored on them. This protects the data in case of any type of computer system failure.
The type of software which is offered in trial form or for a limited period of time is called shareware.
Software which are offered for free in trial form or for a limited time period are called shareware. They operate on the principle that once the user understands what the software can offer they will pay to use it later.
Most shareware software has built in countdowns which start as soon as you start the trial and at the end of which access is automatically revoked. They require the user to form a simple account. These versions generally provide a very basic selection of functions and are used to rake in more paying users.
Types of shareware include:
- Adware: It stands for advertising-supported software where the advertisements generate revenues.
- Demoware: This is a trial version of the original software including all features.
- Crippleware: This software is free but provides limited features till it is purchased.
- Trialware
This provides the user with full feature access for a time limit and then requires purchase.
