A Knowledge organiser that captures the essential knowledge and skills learnt throughout the Year 6 Computing unit Big Data 1.
This resource is designed to support the pupils as they explore how large-scale data collection and transmission systems operate in everyday life. It highlights key vocabulary, technologies and concepts, such as data privacy, encryption, contactless systems and the role of analysts in managing and interpreting data. The pupils will also learn about the use of barcodes, QR codes, RFID and NFC to store and transfer information efficiently. The organiser explains how infrared waves and radio waves enable wireless communication, powering technologies such as remote controls, contactless payments and thermal imaging cameras. It also outlines the process of data encryption, showing how information can be secured using codes that prevent unauthorised access. Through real-world examples, such as how libraries use barcodes to track book borrowing, the pupils will develop an understanding of how businesses and institutions use big data to improve efficiency. The role of a systems or data analyst is introduced, helping the pupils recognise the importance of sorting, modelling and analysing data to solve problems.
