A client process P needs to make a TCP connection to a server process S. Consider the following situation: the server process S executes a socket( ), a bind( ) and a listen( ) system call in that order, following which it is preempted. Subsequently, the client process P executes a socket( ) system call followed by connect( ) system call to connect to the server process S. The server process has not executed any accept( ) system call. Which one of the following events could take place?

Consider three IP networks A, B and C. Host HA in networks A sends messages each containing 180 bytes of application data to a host HC in network C. The TCP layer prefixes a 20 byte header to the message. This passes through an intermediate network B. the maximum packet size, including 20 byte IP header, in each network is:
A : 1000 bytesB : 100 bytes
C : 1000 bytes
The network A and B are connected through a 1 Mbps link, while B and C are connected by a 512 Kbps link (bps = bits per second).
Assuming that the packets are correctly delivered, how many bytes, including headers, are delivered to the IP layer at the destination for one application message, in the best case? Consider only data packets.
