Answer:
a) the average CPI for machine M1 = 1.6
the average CPI for machine M2 = 2.5
b) M1 implementation is faster.
c) the clock cycles required for both processors.52.6*10^6.
Explanation:
(a)
The average CPI for M1 = 0.6 x 1 + 0.3 x 2 + 0.1 x 4
= 1.6
The average CPI for M2 = 0.6 x 2 + 0.3 x 3 + 0.1 x 4
= 2.5
(b)
The average MIPS rate is calculated as: Clock Rate/ averageCPI x 10^6
Given 80MHz = 80 * 10^6
The average MIPS ratings for M1 = 80 x 10^6 / 1.6 x 10^6
= 50
Given 100MHz = 100 * 10^6
The average MIPS ratings for M2 = 100 x 10^6 / 2.5 x 10^6
= 40
c)
Machine M2 has a smaller MIPS rating
Changing instruction set A from 2 to 1
The CPI will be increased to 1.9 (1*.6+3*.3+4*.1)
and hence MIPS Rating will now be (100/1.9)*10^6 = 52.6*10^6.
The while loop has two important parts: (1) a boolean expression that is tested for a true or false value, and (2) a statement or block of statements that is repeated as long as the expression is true.A.TrueB.False
Answer:
True is the correct answer for the above question.
Explanation:
The loop is used to repeat some specifies tasks for a finite amount of time. It is of three types:- For, Do-while and While.The While Loop is a Loop that has two things:- 1. The condition is used to decide that the loop statement executes or not and 2. Some line of the statement which holds the operation which helps the condition to be false after a finite iteration of the loop, so the loop executes finite times.The question-statement also wants to state which is described above. Hence the Question statement is a true statement.Answer:
The given statement is "True".
Explanation:
The while loop is iterating the condition when the condition is true if the condition which is given inside the while loop parenthesis is false it will not iterating the loop that's why sometimes while is also known as an Entry control loop. The while loop has tested the condition for a true or false value that's why the first statement is true.
In the second statement, the statement inside the while loop is executed until the condition of while loop is true when the condition id False it stops the execution of a while loop that's why the second statement is true.
Employee badges are encoded with a private encryption key and specific personal information.
The encoding is then used to provide access to the network. Which of the following describes this access
control type?
A. Smartcard
B. Token
C. Discretionary access control
D. Mandatory access control
Answer:
Option A is the correct answer for the above question.
Explanation:
The above question states that there is some encoded information provided to the employee to access the internet. So how it can be provided. So it is provided with the help of a Smartcard. It is because the smart card is used to hold the secret information which can understand by the swap machine only and it helps the employee to access the internet. So option A is the correct while the other is not because:-
Option B states about the token which is used for the one time only.Option C states about the "Discretionary access control", which is a mechanism to secure the information.Option D states about the Mandatory access control, which is also a mechanism to secure the information.When you create a class and want to include the capability to compare its objects so they can use the Array.Sort() or Array.binarySearch() method, you must _________

You decide to use the motherboard's integrated sound until you can replace the PCI sound card. After removing the PCI sound card and powering on the computer, you have no sound, and the built-in sound card does not show up in Device Manager. Which should you do to solve the issue?
Keep the PCI sound card in until you get a new one, otherwise you will not have sound. The integrated sound still requires some kind of sound card.
Final answer:
To resolve the issue with the unrecognized integrated sound card, check and enable it in BIOS settings, examine Device Manager for hardware conflicts, ensure proper drivers are installed, and consider a system restore or contacting support.
Explanation:
When the integrated sound card is not recognized after removing a PCI sound card, you'll need to perform a few troubleshooting steps. Firstly, ensure that the integrated sound card is enabled in the BIOS settings. You might need to restart your computer and press a specific key (such as F2, Del, or F10) to enter the BIOS setup. Once there, look for audio settings and ensure the onboard audio is enabled.
Next, check for hardware conflicts or issues in Device Manager, even though the sound card is not listed. View hidden devices to ensure there are no conflicts with the sound card's drivers. If necessary, install the correct drivers for your motherboard's audio chipset from the manufacturer's website.
If the problem persists, consider performing a system restore to a point when the sound was working, or consult the motherboard manual for troubleshooting tips, or contact customer support for your motherboard.

Which of the following is an advantage to using internal databases for information? A. Internal information is accurate and complete. B. Internal information is in a form that is useful for making marketing decisions. C. They can be accessed quickly and cheaply. D. Internal information sources are easy to manage. E. The information stored in internal databases is always current.
Answer:
C. They can be accessed quickly and cheaply.
Explanation:
An internal database is information that can be obtained inside the company through internal networks. This information can be easy to get as it is in the network of the company and you have access to it and it also have a low cost as you don't have pay money to get it. According to this, the answer is that an advantage to using internal databases for information is that they can be accessed quickly and cheaply.
The other options are not right because internal information can be outdated and incomplete if it is not updated by people in the company and it can be found in different forms and it is not always easy to manage as this depends on the applications used and how the company decides to visualize it.
Describe how you could obtain a statistical profile of the amount of time spent by a program executing different sections of its code. Discuss the importance of obtaining such a statistical profile
Answer:
Explanation:
It can be said that the best way to obtain such a statistical profile would be to issue a periodic timer interrupt, then you would simply need to monitor which what code was running when the interruption took place.

Visual Basics: 1 ) Write an if/else statement that compares the double variable pH with 7.0 and makes the following assignments to the bool variables neutral, base, and acid:
false, false, true if pH is less than 7
false, true, false if pH is greater than 7
true, false, false if pH is equal to 7
2) Visual Basics: Write an if/else statement that adds 1 to the variable minors if the variable age is less than 18, adds 1 to the variable adults if age is 18 through 64, and adds 1 to the variable seniors if age is 65 or older.
Answer:
visual basic: 1)
Module PHmodule
Sub Main()
'Creating a variable for each entity
dim ph as double = 0.0, neutral,base,acid as boolean
'Writing a line to show user what to do
console.writeline("Enter the pH :")
'Taking the value
ph=console.readline()
'using if & elseif statement for distingushing the values into correct catagories
if ph<7.0 then
neutral=false:base=false:acid=true
elseif ph>7.0 then
neutral=false:base=true:acid=false
elseif ph=7.0 then
neutral=true:base=false:acid=false
end if
'Printing the result
console.writeline(" Neutral :" & Neutral)
console.writeline(" base :" & base)
console.writeline(" acid :" & acid)
'command for staying in the command prompt for reading the result
console.readline()
End Sub
End Module
visual basic: 2)
Module AGEmodule()
Sub Main()
'Creating a variable for each entity
dim age,minors,adults,seniors as integer = 0
'Taking age from user
console.writeline("Enter the age")
age=console.readline()
'using if & elseif statement for checking the age differnce
if age<18 then'
minors +=1
else if age>18 and age<64 then
adults +=1
else if age>64 then
seniors +=1
end if
'printing result
console.writeline("minors="&minors)
console.writeline("adults="&adults)
console.writeline("seniors="&seniors)
'command for reading the result
console.readline()
End Sub
End Module
Explanation:
visual basic 1) it is very simple program which allow us to find if the substance is acidic, basic or neutral. we use sim statement for making a variable as double (gives value in decimal) which allow to take a value from the user through console.readline() command and then by using the if statement we apply the condition if the ph is less then, greator then or equal to 7.0 value. thus the program gives us the answer. console.writeline() command is used to print a command on the screen while console.readline() command let us read the lines until we press enter.
visual basic 2)a program which allow us to count and add number of persons according to their age. we use dim statement for creating the variable as integers in which we take the age from user and then after checking it through if statement we increment according to three categories i.e. minors, adults, seniors. the console.writeline() command allow us to print anything on screen and console.readline() allowus to take value while compiling.
thank you...
