Consider two hosts, Host A and Host B, transmitting a large file to Server C over a bottleneck link with a rate of R kbps. To transfer the file, the hosts use TCP with the same parameters (including MSS and RTT) and start their transmissions at the same time. Host A uses a single TCP connection for the entire file, while Host B uses 9 simultaneous TCP connections, each for a portion (i. e., a chunk) of the file. What is the overall transmission rate achieved by each host at the beginning of the file transfer
