Understanding File Descriptors in Linux

File descriptors are a core concept in Linux and other Unix-like operating systems. They provide a way for programs to interact with files, devices, and other input/output (I/O) resources. Simply put, a file descriptor is like a "ticket" or "handle" that a program uses to access these resources. Every time a program opens a file or creates an I/O resource (like a socket or pipe), the operating system assigns it a unique number called a file descriptor. This number allows the program to read, w
