Benefits of technology

This technology helps protect against viruses that can harm computer systems without having them deleted or damaged essential file content on disk drives. It also allows for more efficient use of space while still maintaining high-level safety measures like encryption techniques.

Problems solved by technology

Technological Problem: Current methods for protecting important files like documents stored inside memory partitions cannot fully stop harmful virus attacks without affecting their original content. Additionally, current techniques require expensive hardware devices attached outside these memories which increases costs associated with maintaining them.
