A user queries the Item table in the TAL Distributors database over the company intranet

For the following exercises, you will answer problems and questions from management at TAL Distributors. You do not use the TAL Distributors database for any of these exercises.

A user queries the Item table in the TAL Distributors database over the company intranet. Assume the Item table contains 5,000 rows, each row is 1,000 bits long, the access delay is 2.5 seconds, the transmission rate is 50,000 bits per second, and only 20 of the 5,000 rows in the Item table satisfy the query conditions. Calculate the total communication time required for this query based on retrieving all table rows one row at a time, and then calculate the total communication time required based on retrieving the 20 rows that satisfy the query conditions in a single message.
