Refer to Figure 1 - A recv( ) Primitive:

a)Explain the purpose of the recv() primitive identifying the source buffer from which the incoming data stream originates.

b)Assuming the test condition within the whlle loop is true i.e. numBytes > 0, explain what this means in terms of the status of the socket identified by the descriptor clntSock.

c) Assume a properly formatted HTTP GET request is sent to a HTTP server containing this code. Explain the problem associated with this implementation of the recv() primitive and how this problem might be addressed.
