Advantages and disadvantages of using computers

Computers transform how we work, learn and communicate — but they also carry costs and risks. A balanced answer always shows both sides.

• Speed and accuracy: repetitive calculations done in seconds without tiring.
• Storage: enormous amounts of data in a small space, easy to search.
• Communication: email, messaging and video calls across the world.
• Automation: dangerous or boring jobs done by machines.

• Cost of equipment, software, electricity and maintenance.
• Job losses where automation replaces people.
• Health issues: eye strain, poor posture (ergonomics), inactivity.
• Security and privacy risks: viruses, data theft, scams.
• Dependence: when systems fail, work can stop entirely.
