Cygwin consists of two parts: a dynamic-link library ( DLL ) as an API compatibility layer providing a substantial part of the POSIX API functionality, and an extensive collection of software tools and applications that provide a Unix-like look and feel.
Cygwin consists of a library that implements the POSIX system call API in terms of Win32 system calls, a GNU development toolchain ( including GCC and GDB ) to allow software development, and a large number of application programs equivalent to those on Unix systems.
