Learning Objectives

• Define utility software and how it differs from application software.
• Categorize utilities: file, disk, security, backup, monitoring.
• Give business-relevant examples (antivirus, backup, Task Manager).

What is Utility Software?

Utilities are system software that maintain, protect, and optimize the computer. They are not the programs users open to write a report (that is application software).

• Keep the OS and disks healthy
• Reduce security risk
• Recover from failure (backup)

File Management Utilities

• File managers: Explorer, Finder — copy, move, properties
• Compression: ZIP, 7z — smaller transfers
• Search: find files by name or content

Disk Management

• Cleanup: temp files, cache
• Defragmentation: HDDs only — not needed for SSDs
• CHKDSK / Disk Utility: file-system errors
• Partitioning: divide a drive (advanced; lab caution)

Security Utilities

• Antivirus / anti-malware (definitions must stay current)
• Host firewall
• Password manager (better than a notebook)

Utilities reduce risk; they do not replace user caution (phishing).

Backup and Recovery

• File backup: selected folders
• System image: whole disk for restore
• Cloud backup: off-site copy (also a confidentiality decision)

3-2-1 idea: three copies, two media, one off-site — exam-friendly mnemonic.

Monitoring and Optimization

• Task Manager / Activity Monitor: CPU, RAM, disk, network
• Startup programs: too many slow boot
• End a hung process — last resort, save work first

Business practice

• Standardize antivirus and backup on lab/office PCs
• Built-in Windows tools vs paid suites: cost vs features
• Nepal: mobile data + cloud backup — bandwidth and privacy

Key Takeaways

• Utilities are system software for health, security, and recovery.
• Do not defragment SSDs; do keep backups.
• Task Manager is the first check when a PC “feels slow.”
