Wi-Fi - GCSE Computer Science Definition

Wi-Fi is a technology that allows devices like laptops, smartphones, and tablets to connect to the internet without using wires. It uses radio waves to send and receive data between your device and a router, which is connected to the internet. This means students can access data from the web, send emails, and stream videos as long as they are within range of a Wi-Fi network. Wi-Fi is very useful in schools, homes, and public places because it makes it easy for multiple devices to connect to the internet at the same time without needing physical connections. Understanding Wi-Fi is important in GCSE Computer Science as it helps explain how networks work and how data travels over them.
