and i request all please try to explan in simple term and in conventational language ..instead of giving stright defination.

thanks to all

replicate generates multiple straight flows as the output where as broadcast results single fanout flow.

replicate improves component parallelism where as broadcast improves data parallelism.

Broadcast - Takes data from multiple inputs, combines it and sends it to all the output ports.

  Eg - You have 2 incoming flows (This can be data parallelism or component parallelism) on Broadcast component, one with 10 records & other with 20 records. Then on all the outgoing flows (it can be any number of flows) will have 10 + 20 = 30 records

Replicate - It replicates the data for a particular partition and send it out to multiple out ports of the component, but maintains the partition integrity.

Eg - Your incoming flow to replicate has a data parallelism level of 2. with one partition having 10 recs & other one having 20 recs. Now suppose you have 3 output flos from replicate. Then each flow will have 2 data partitions with 10 & 20 records respectively.
