Consider three different processors p1, p2, and p3 executing the same instructions set. p1 has a 3 ghz clock rate and a cpi of 1.5. p2 has a 2.5 ghz and cpi of 1.0. p3 has a 4.0 ghz clock rate and has a cpi of 2.2.
a. which processor has the highest performance expressed in instruction per second?
b. if the processors each execute a program in 10 seconds, find the number of cycles and the number of instructions.
c. we are trying to reduce the execution time by 30% but this leads to an increase of 20% in the cpi. what clock rate should we have to get this time reduction.

When creating a budget, log fixed expenses before income. after income. after savings. at the top.

Given a link with a maximum transmission rate of 32.8 mbps. only two computers, x and y, wish to transmit starting at time t = 0 seconds. computer x sends filex (4 mib) and computer y sends filey (244 kib), both starting at time t = 0. statistical multiplexing is used, with details as follows packet payload size = 1000 bytes packet header size = 24 bytes (overhead) ignore processing and queueing delays assume partial packets (packets consisting of less than 1000 bytes of data) are padded so that they are the same size as full packets. assume continuous alternating-packet transmission. computer x gets the transmission medium first. at what time (t = ? ) would filey finish transmitting? give answer in milliseconds, without units, and round to one decimal places (e.g. for an answer of 0.013777 seconds you would enter "13.8" without the quotes)

Jake really works well with numbers and is skilled with computers but doesn't work well with others. which of the jobs discussed in this unit might be best for jake? why?
