A user queries the Part table in Premiere Products database over company intranet. Suppose the Part table contains 5,000 rows, each row is 1,000 bits long, access delay is 2.5 seconds, transmission rate is 50,000 bits per second, and only 20 of 5,000 rows in Part table satisfy the query conditions. Compute total communication time required for this query based on retrieving all table rows one row at time; then compute total communication time required based on retrieving 20 rows that satisfy query conditions in single message. You don't need Premiere Products database to answer this question.

Total communication time to retrieve all rows, one row at a time is?
Total communication time to retrieve 20 rows in one message is?
