Fascinating Fact:

Many cards also use a microchip because it can store encrypted data and reduce counterfeiting, although it cannot stop fraud completely.

In KS3 ICT, data input is about getting information into a system in a reliable way. This includes manual entry, scanning, card readers, and sensors, plus checks that spot errors before data is saved and used.

Key Terms

Input device: Hardware that sends data into a computer, such as a keyboard, scanner, card reader, or microphone.
Validation: An automatic rule that checks data is sensible, for example a range check for age or a format check for a postcode.
Verification: A way to reduce mistakes by checking data has been entered correctly, such as double entry or proofreading.

Frequently Asked Questions (Click to see answers)

What is the difference between validation and verification?

Validation checks whether data follows rules, such as being in the right range or format. Verification checks whether the data was entered correctly, for example by typing it twice and comparing.

What are common data input devices in KS3 ICT?

Common input devices include a keyboard and mouse, scanners for paper documents, microphones for voice input, cameras for images, and sensors or data loggers for readings like temperature and light.

How does a bank card reader use data input?

A card reader inputs data from the card so a system can identify the account and process a transaction. Using the correct format and security checks helps reduce errors and unauthorised copying.
