2. Consider a 2 GHz processor where two important programs, A and B, take one second each to execute. Each program has a CPI of

allsm [11]

Answer:

program A runs in 1 sec in the original processor and 0.88 sec in the new processor.

So, the new processor out-perform the original processor on program A.

Program B runs in 1 sec in the original processor and 1.12 sec in the new processor.

So, the original processor is better then the new processor for program B.

Explanation:

Finding number of instructions in A and B using time taken by the original processor :

The clock speed of the original processor is 2 GHz.

which means each clock takes, 1/clockspeed

= 1 / 2GH = 0.5ns

Now, the CPI for this processor is 1.5 for both programs A and B. therefore each instruction takes 1.5 clock cycles.

Let's say there are n instructions in each program.

therefore time taken to execute n instructions

= n * CPI * cycletime = n * 1.5 * 0.5ns

from the question, each program takes 1 sec to execute in the original processor.

therefore

n * 1.5 * 0.5ns = 1sec

n = 1.3333 * 10^9

So, number of instructions in each program is 1.3333 * 10^9

the new processor :

The cycle time for the new processor is 0.6 ns.

Time taken by program A = time taken to execute n instructions

= n * CPI * cycletime

= 1.3333 * 10^9 * 1.1 * 0.6ns

= 0.88 sec

Time taken by program B = time taken to execute n instructions

= n * CPI * cycletime

= 1.3333 * 10^9 * 1.4 * 0.6

= 1.12 sec

Now, program A runs in 1 sec in the original processor and 0.88 sec in the new processor.

So, the new processor out-perform the original processor on program A.

Program B runs in 1 sec in the original processor and 1.12 sec in the new processor.

So, the original processor is better then the new processor for program B.

stellarik [79]

Answer:

I would propose Comodo Firewall to my schoolmate. It is very easy to understand and have an appealing graphical UI. It gives the most significant level of security from dangers. It checks all the traffic going to the framework and leaving the framework. It quickly cautions you when there is any sort of suspicious action. There are no mind boggling design issues. It learns the conduct of the client to convey customized protection. It gives you the usefulness of Spyware filtering and infection checking in a single tick. There are a lot more functionalities that the firewall gives to its clients.

A milk carton can hold 3.78 liters of milk. Each morning, a dairy farm ships cartons of milk to a local grocery store. The cost

makvit [3.9K]

Answer:

milk_produced = float(input("Enter the total amount of milk produced in the morning: "))

liter_cost = float(input("Enter the cost of producing one liter of milk: "))

carton_profit = float(input("Enter the profit on each carton of milk: "))

carton_needed = round(milk_produced / 3.78)

cost = milk_produced * liter_cost

profit = carton_profit * carton_needed

print("The number of milk cartons needed to hold milk is " + str(carton_needed))

print("The cost of producing milk is " + str(cost))

print("The profit for producing milk is " + str(profit))

Explanation:

*The code is in Python.

Ask the user to enter milk_produced, liter_cost and carton_profit

Calculate the number of milk cartons needed, divide the milk_produced by the capacity (3.78) of a cartoon and round the result

Calculate the cost, multiply the milk_produced by liter_cost

Calculate the profit, multiply the carton_profit by carton_needed

Print the results
