Business Use: Quick generation of invoices, payroll, and financial reports.

2. Accuracy

Computers perform operations with very high precision.
Errors usually occur due to wrong input (human error), not because of the machine.
Business Use: Accurate calculation of profits, taxes, interest, etc.

3. Automation

Once programmed, computers can perform tasks automatically without human intervention.
Example: ATM machines dispensing money, or online order processing systems.

They can perform the same task repeatedly with consistent accuracy.
Business Use: Running 24/7 operations like banking, stock exchanges, and e-commerce websites.

Computers can store a huge amount of data in a small physical space.
Data can be retrieved instantly whenever required.

Business Use: Video conferencing, e-commerce, online banking, global collaboration.

8. Multitasking

Computers can perform multiple tasks at the same time.
