Digital networks are systems that connect computers and devices to share information and resources. They use various technologies, such as the Internet, Wi-Fi, and Bluetooth, to enable communication between users. These networks can be local, like a home network, or global, like the World Wide Web. In a digital network, data is transmitted in the form of packets, which are small units of information. This allows for efficient communication and resource sharing, such as accessing files, streaming videos, or using online services. Digital networks play a crucial role in modern life, facilitating connectivity and collaboration across the globe.
