A user queries the Tasks table in the BITS Corporation database over the company intranet.  Assume the Tasks 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 per second, and only 20 of the 5,000 rows in the Tasks 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 base on retrieving the 20 rows that satisfy the query conditions in a single message.
