Question

Assume you are running an application on your hand-held device to update customer accounts. You enter a 12 byte customer account number into your application in your hand-held device. Your application sends customer account number to a server program P. Program P searches a database for customer account number. Suppose two input/outputs are needed to locate a customer, one to read the index and second to read the record. The server program then sends customer information (120 bytes) back to your hand-held device. Assume that the data rate between your hand-held and the server is 1200 bps only. The server can complete 10 inputs and outputs per second on the average. What is response time you experience ignoring the propagation delay? You can assume that each byte occupies 10 bits in the network.
