Network connections refer to the links between different devices that allow them to communicate and share information. These connections can be established through various means, such as wired cables or wireless signals. Common examples include Wi-Fi networks, which use radio waves, and Ethernet connections, which use physical cables to connect devices like computers and printers. In a network, devices can exchange data, access shared resources, and connect to the internet. This interconnectedness enables activities like browsing the web, streaming videos, and sharing files. Properly configured network connections ensure efficient communication and enhance overall productivity in both personal and professional settings.
