Fixed Polling link |
||
Line 46:
The read operation is a blocking type operation so we have two options, either Polling (i.e. continually checking if data is there) or Blocking (i.e. only processing when data is actually available, otherwise sleeping).
(<i>Polling is "the sequential interrogation of devices for various purposes, such as avoiding contention, determining operational status, or determining readiness to send or receive data." - Wikipedia ( http://en.wikipedia.org/wiki/Polling )</i>)
We choose Blocking because we don't want to waste CPU time Polling the network for messages, we just want to sleep until messages are available. Hence we create a Thread to read from the Network, let's call it Network Manager Read.
