This “language” is all over the place:

Starting with 101, 102 in the first example, for some reason.

When a process or I/O device makes a successful request, the kernel returns a file descriptor to that process

I/O device?

By default, three types of standard POSIX file descriptors exist in the file descriptor table

Types?

Apart from them, every other process has its own set of file descriptors, but few of them (except for some daemons) also utilize the above-mentioned file descriptors to handle input, output, and errors for the process.

What?

It makes an impression of a poor translation of a pretty low-effort article, tbh. You’re better off just reading the corresponding APUE section, which you must have read anyway.
