In which process is the processing of network requests carried out in the operating system?

In the Android operating system, network requests are processed across several layers, but the key process is the system process netd (Network Daemon). It is responsible for managing network interfaces, routing, firewalls, and other network functions.

Additionally, applications themselves handle network requests within their processes, using Android APIs (for example, through HttpURLConnection or OkHttp). However, low-level packet processing and routing are performed by the Linux kernel and system daemons such as netd.

Thus, network requests pass through:

1. The application — formulates the request.
2. System libraries and APIs — ensure data transfer.
3. The netd process and the Linux kernel — manage network interfaces and routing.

This ensures efficient and secure processing of network operations in Android.
