How is data physically sent over a network?

Data is physically sent over a network through frames that are transmitted over various media, including both Ethernet cables and Wi-Fi. This means that when data is being transmitted, it is organized into frames, which are packets of data that contain not only the actual information being sent but also additional information needed for routing it to the correct destination.

Ethernet cables are commonly used for wired connections, enabling high-speed data transmission between devices within a local area network (LAN). On the other hand, Wi-Fi enables wireless communication, allowing devices to connect without physical cables. Both technologies utilize frames to encapsulate and transmit data, making them integral parts of how data is handled across both wired and wireless networks.

While some options mention specific mediums, they do not encompass the broad approach of how data can travel across different types of networks. This is significant because understanding the versatility of network communication is essential for comprehending how data transmission works in real-world scenarios.
