- Answer: Data communication (sharing info) and resource sharing (e.g., printers) make networks essential, saving time and costs.
- Description: Networks let you email files (communication) or print from one printer across an office (resource sharing). This efficiency boosts productivity—like students sharing notes online—showing why networks are vital in modern life.
