10 Operasi I/O asinkron tdk menyebabkan proses di blok
TCP Echo Server Operasi I/O sinkron menyebabkan proses diblok sampai operasi I/O komplit. Operasi I/O asinkron tdk menyebabkan proses di blok Blocking, non blocking, I/O multiplexing dan signal driven I/O adalah termasuk operasi I/O sinkron.

11 Select () The select() system call allows us to use blocking I/O on a set of descriptors (file, socket, …). For example, we can ask select to notify us when data is available for reading on either STDIN or a TCP socket.

12 Contoh select () int select( int maxfd, fd_set *readset,
fd_set *writeset, fd_set *excepset, const struct timeval *timeout); maxfd: highest number assigned to a descriptor. readset: set of descriptors we want to read from. writeset: set of descriptors we want to write to. excepset: set of descriptors to watch for exceptions. timeout: maximum time select should wait
