Capabilities and Limitations of ICT

CAPABILITIES AND LIMITATIONS OF ICT

CORE USES OF ICT

Fast Repetitive Processing

Computers can carry out millions of repetitive calculations per second - something that would be very labour intensive and costly without computers.

E.G.

• Banking
• Utility Billing (Gas etc.)
• Research
• Payroll

Vast Storage Capacity

Computer systems store 100s billions of data items. With the large capacity of modern hard drives, vast amounts of data can be stored electronically.

E.G.

• Banking records
• Customer databases
• Stock control
• Government databases
• Internet
