Sir Tom taught us about Encryption,Version ,Backup and Data Compression.
 |
| Encryption-creating a password in a document so that others can't read your file. |
 |
| Version- by creating multiple versions,you can compare it with you're last version.If your teacher wants the first version and you submitted the second version,you can easily pass the first version.It is really helpful. |
 |
| Backup-creating another file in another computer so that in case for example there is a virus in your laptop,at least you can pass your file saved in another computer. |
 |
| Data Compression-Compressing data to have more space to use |
