Which statement best justifies the use of a high-speed cache in a CPU?

1 answer:

6 0

Cache memory is a high-speed memory that stores the instructions and data that have been frequently accessed. It decreases the time it takes to decode the instructions stored in the instruction pipeline.

A. It decreases the time it takes to decode instructions stored in the instruction pipeline.

Explanation:

Whenever an instruction is invoked or some data is accessed, the CPU looks for it in the cache memory before accessing the main memory.

If the content is found in the cache memory, it accessed from there and then and hence the access time and decode time is reduced as there were no main memory lockups.

How Many Slides to Use in a Presentation and for how long?

In the past if you asked a presentation skills “pundit” you were likely to hear “one slide per minute,” but times are changing and I don’t think the answer is as simple as a certain number of slides per minute. A presentation slide is supposed to be on for 15 seconds and stop to ask if anyone has any questions, if you are explaining something or reading alond with the slide it could be as long as you want it to be.

In python 3.17 LAB: Convert to dollars

krok68 [10]

To convert the inputs to dollars and cents, we make use of a combination of multiplication and addition.

The program written in Python where comments are used to explain each line is as follows:

#This gets input for the number of quarters

quarters = int(input("Quarters: "))

#This gets input for the number of dimes

dimes = int(input("Dimes: "))

#This gets input for the number of nickels

nickels= int(input("Nickels: "))

#This gets input for the number of pennies

pennies= int(input("Pennies: "))

#This converts the amount to dollars and cents

dollars = quarters * 0.25 + dimes * 0.10 + nickels * 0.05 + pennies * 0.01

#This prints the amount to 2 decimal places

print("Amount ${:.2f}".format(dollars))
