1. We know that print spooler is the service required for printing from a system. Assume to have a network printer with ten computers who require to access such service. Consider such service to receive print requests from the processes may be across similar host system and a TCP socket to receive print requests from the processes on other hosts. This could be addressed using I/O multiplexing. Describe any two techniques amongst SELECT, FORK, FNDELAY-FIONBIO or SIGIO to handle such multiplexing
