Study Notes
Computer Maintenance Tools
- Anti-virus software scans a computer system for viruses, detects, and removes them to prevent damage or data loss.
- Data compression reduces the size of a file or set of files to save storage space and facilitate faster file transfer.
Disk Management
- Disc defragmentation rearranges fragmented data on a hard drive to improve data access speed and overall system performance.
