A bindshell is a remote shell connection, similar to the connection a telnet client preforms to a telnet server. Any operating system supporting a TCP stack and a shell will have the potential to provide bindshell access.
Typically, when a system is successfully hacked/attacked by an exploit, it will execute code that sets up the bindshell listener. This allows access to the system from any device capable of connecting to the bindshell port.
There are various methods to setup a bindshell. For example, exploits use shellcode to spawn threads. From an operating level the tool commonly used is netcat, which can tunnel stdout and stdin over TCP connections.
