Fascinating Fact:

Data can be entered in different formats, such as numbers, text, dates, and Boolean values like true or false.

In KS3 ICT, data input is about entering data into the right place and in the right format. Good input uses clear field names, suitable data types, and sensible checks so mistakes are spotted before data is saved.

Key Terms

Field: A single category of data in a record, such as surname, postcode, or date of birth.
Data type: The kind of data a field can store, such as whole numbers, text, or a yes or no value.
Validation: An automatic check that data follows rules, such as a range check for age or a format check for an email address.

Frequently Asked Questions (Click to see answers)

What is data input in ICT?

Data input in ICT is the process of entering raw facts into a computer system. This can be done by typing, importing a file, or using an input device such as a scanner or microphone.

What is a data type in a database?

A data type is a rule that controls what kind of data a field can hold. It helps the system store and process data correctly, for example keeping numbers as numbers instead of letters.

What does Boolean mean in ICT?

Boolean means a value that has only two possible states. In ICT, it is often used for questions with two outcomes, such as on or off, yes or no, or true or false.
