18. We have two types of machine as follows: Processor Clock Rate (MHz) MIPS rate CPU time (sec) Machine A 5 1 12 x Machine B 25 18 x Mache A requires 12 times longer than Machine B measured in CPU time. For example, a program takes 1 second in Machine B will take 12 seconds. 1) What is the relative size of the instruction count for the program running on the two machines

When you type the pwd command, you notice that your current location on the linux filesystem is the /usr/local directory. answer the following questions, assuming that your current directory is /usr/local for each question. a. which command could you use to change to the /usr directory using an absolute pathname? b. which command could you use to change to the /usr directory using a relative pathname? c. which command could you use to change to the /usr/local/share/info directory using an absolute pathname? d. which command could you use to change to the /usr/local/share/info directory using a relative pathname? e. which command could you use to change to the /etc directory using an absolute pathname? f. which command could you use to change to the /etc directory using a relative pathname?

Scientists have changed the model of the atom as they have gathered new evidence. one of the atomic models is shown below. what experimental evidence led to the development of this atomic model from the one before it? a few of the positive particles aimed at a gold foil seemed to bounce back. the colors of light emitted from heated atoms had very specific energies. experiments with water vapor showed that elements combine in specific proportions. cathode rays were bent in the same way whenever a magnet was brought near them.

Aproject involves many computing systems working together on disjointed task towards a single goal what form of computing would the project be using
