2-15 - Uses and limitations of ICT

What has ICT given us?

• Fast, repetitive processing

One of the biggest reasons for using computers is because they can perform calculation very quickly.

• Vast storage capacity in a small space

The ability to store data electronically has considerably reduced the size of an area needed to store the data eg. Data sticks can now hold more data than a room of filing cabinets.

• Fast & flexible searching of data

 IT systems allow processing of large data very quickly, eg. Searching for a product on Amazon.

• Improved presentation of data

The use of multimedia technology has given us the ability to use a wide range multimedia resources to present data effectively. Such as the weather forecast information on the news

• Improved accessibility of information and services

With the ability to share resources online, individuals and organisations have much more access to information now.

What are the limitations of ICT

• Understanding speech
• High cost
• Reliant on electricity
• Quality of output (controlled by processing of data)
• Not model opinions
• Digital output compared to analogue output of sound (Quality)
