Data
The term Data refers to the idea that information or knowledge can be put into a form that makes it easy to use, understand, process and visualise.
Data can be expressed as words, numbers, images, symbols graphs and in other ways.
The Data section of this website looks at:
- How Data is stored on a computer as Binary.
- How Binary can be made slightly easier for humans to work with by converting it into Hexadecimal.
- How computers can do basic arithmetic (add, multiply etc) using Logic Gates
- How Data can be processed using Algorithms, and specifically how it is sorted and searched.
- How files can be made smaller using Compression
- How data can be made much harder to read without permission with Encryption
- And how it can be protected from loss by good Backing Up policies.
