Networking in Linux

In Linux, networking is implemented in the kernel, which means that it is a part of the operating system. The kernel includes several components that work together to enable networking, including device drivers, protocol implementations, and system calls.

When a user wants to send or receive data over a network, they can do so using any of the networking applications available in Linux, such as ping, traceroute, telnet, or ssh. These applications use system calls to communicate with the kernel and request that data be sent or received over the network.

The kernel communicates with the network hardware using device drivers, which are software programs that allow the kernel to access and control the hardware. Different drivers are needed for different types of network hardware, such as Ethernet or Wi-Fi.

The kernel also implements several networking protocols, which are rules and standards that define how data is formatted and transmitted over the network...
