The ACK indicates that a host is acknowledging having received some data, and the PSH,ACK indicates the host is acknowledging receipt of some previous data and also transmitting some more data. Google will let you search for more info about basic TCP communication.   ACK means that the machine sending the packet with ACK is acknowledging data that it had received from the other machine. In TCP, once the connection is established,   all   packets sent by either side will contain an ACK, even if it's just re-acknowledging data that it's already acknowledged.
