What is ICT? Find out in this KS3 quiz. ICT consists of all technical means used to handle information and aid communication, including both computer and network hardware as well as necessary software. An ICT system also usually includes the internet. It is much more than just computer science, it is also about the people who use them. From your studies, you will find that ICT systems are used in most environments from homes and businesses to medicine and farming.
When used properly, ICT can add a lot of extra power to what we do. One key feature is how we can handle data. Using an ICT system, we can obtain, process and produce a set of results much faster than before. Computers were a significant step forward in data handling but when the power of a communications network was added, that was possibly an even greater leap forward. Just think - before the internet and mobile phones, you needed to go to a library, find the right books, find the right pages and make notes. Using ICT, you can do the same from one place in a fraction of the time.

A digital signal (one consisting of a string of only 1's and 0's) can be all three - better quality, more reliable and accurate. The label 'Digital' is often used to impress consumers but it does NOT describe the quality or reliability of the equipment itself, which is what this question asked
