Explanation & answer:
To understand technical questions, it is necessary to understand all technical terms used.
Here,
CPI = cycles per instruction
clock rate = number of cycles the processor generates.
1 GHz = 1,000,000,000 cycles per second
= 1 nanosecond / cycle.
Processor A
CPI = 1.2 cycles per instruction
Frequency 1 GHz.
time per instruction,
Ta = (1.2 cycles/instr. )/ 1 GHz
= (1.2 cycles / instr. ) / (1 cycle / nanosecond)
= 1.2 nanoseconds / instruction
Processor B
CPI = 2.0 cycles per instruction
Frequency 2 GHz.
time per instruction,
Tb = (2.0 cycles/instr. )/ 2 GHz
= (2 cycles / instr. ) / (2 cycles / nanosecond)
= 1.0 nanosecond / instruction
Processor C
CPI = 2.6 cycles per instruction
Frequency 2.5 GHz.
time per instruction,
Tc = (2.6 cycles/instr. )/ 2.5 GHz
= (2.6 cycles / instr. ) / (2.5 cycles / nanosecond)
= 1.1 nanoseconds / instruction
The fastest is Tb = 1.0 nanosecond/instruction
The slowest is Ta = 1.2 nanoseconds/instruction
The ratio fastest/slowest = 1.2/1.0 = 1.2 times as fast
Note: cycles per instructions (CPI) are always in whole number cycles. CPI for different instructions may vary according to complexity of instruction. Decimal CPI usually indicates the value is a weighted mean of the set of instructions.
The weakest link in the security of an IT infrastructure is the server.
A. True
B. False
Answer:
False
Explanation:
"The weakest link in the security of an IT infrastructure is not a server, it is a internet that is weakest link. Because connecting your device or computer to internet immediately exposes them to attack. Through intrusion detection system (IDS) we can examine IP data stream for common attack and malicious intent patterns."
Final answer:
The assertion that the server is the weakest link in IT security is false, as human factors often represent a greater risk. Security threats include local networks, viruses, and interconnected device vulnerabilities that could lead to cascade failures.
Explanation:
The statement 'The weakest link in the security of an IT infrastructure is the server' is False. While servers can be vulnerable, they are not inherently the weakest link in security. In fact, the weakest link is often due to human factors, such as social engineering or poor password practices. Comprehensive cybersecurity measures must cover a wide range of components including local networks, protection against viruses, and guarding against groups of compromised computers known as botnets.

How are arrays stored in memory?
In Java, arrays are objects, therefore just like other objects arrays are stored in heap area. An array store primitive data types or reference (to derived data) types Just like objects the variable of the array holds the reference to the array.

In at software development, baselines are created at various planned points in the software development process. The baseline is also very useful when you need to create a “branch” to provide an emergency fix based off of some baseline of code that was delivered to a customer.
Write a C++ program that prompt the user to enter three points (x1, y1), (x2, y2), (x3,y3) of a triangle and
Answer:
#include<iostream>
using namespace std;
int main(){
int x1,x2,x3;
int y1,y2,y3;
cout<<"Enter the value of first point(x1,y1): ";
cin>>x1>>y1;
cout<<"\nEnter the value of second point(x2,y2): ";
cin>>x2>>y2;
cout<<"\nEnter the value of third point(x3,y3): ";
cin>>x3>>y3;
}
Explanation:
first include the library iostream for use the input/output commands
then, write the main function. within the main function declare the variable which store the value of points.
after that, use the 'cout' for output. It has the function which print the value or message on the screen.
and 'cin' is used to store the value in the variable.
So, in the above code cout ask for enter the value of point and after enter value by user, cin store in the variables.
Note: you have to enter two value with space or by enter.

how do computers benefit individuals' health care?
Answer:
By having personal health records available on a computer, more doctors have access to an individual's information. This allows doctors to view all prescriptions that a person is on, which can help protect patients from conflicting medications to be taken at once, and can save time if a patient doesn't have to redo tests and procedures because the doctor doesn't have the records.

Do you think robots will take millions of jobs when they're put in different positions such as doctors or taxi drivers?
Yes, of course.
When you replace people with technologically advanced robots, it can disturb the economic factors. Although I don't agree with using robots as an every day, common thing, such as self-driving cars or like in the question, using robots as doctors. Technology is technology, it will always need updates and sometimes they break down or need repairs, so that could provide jobs for people; tech jobs that is. Not everybody is tech savvy though, but you learn. I still don't agree with it, but it is what it is.

Write a program to read 2 numbers and display the largest of the two. You should use scanfto read the two numbers and use if statement to see which number is larger
Answer: in C
#include <stdio.h>
int main(){
int num1, num2;
printf("Enter first number :: ");
scanf("%d", &num1);
printf("Enter second number :: ");
scanf("%d", &num2);
if(num1 > num2){
printf("%d is larger than %d\n", num1, num2);
} else if (num2 > num1) {
printf("%d is larger than %d\n", num2, num1);
} else{
printf("Both of them are equal\n");
}
return 0;
}
Write and test a Python program to find and print the largest number in a set of real (floating point) numbers. The program should first read a single positive integer number from the user, which will be how many numbers to read and search through. After reading in all of the numbers, the largest of the numbers input (not considering the count input) should be printed.

Sort the array A = [ 3, 1, 4, 1, 5, 9, 2, 6, 5] using insertion sort and illustrate your solution?
Answer:
Sorted list : [1, 1, 2, 3, 4, 5, 5, 6, 9]
Explanation:
For j= 2 to length of A
we find the place for A[j] in the sub-array A[1,..., j]
Taking i from j-1 to 1, if A[i] is greater than A[j] we shift it to right.

The process of representing data in digital form so it can be used by a digital computer is called decimal byterepresentation. - true or false
The process of turning data into digital form for use by a digital computer is called 'digitization', not 'decimal byte representation'.
Explanation:As asked here The statement the process of representing data in digital form so it can be used by a digital computer is called decimal byte representation - is false. The term is not 'decimal byte representation'. The correct term for this process is 'digitization'. Digitization is the process of converting information into a digital (i.e., computer-readable) format, where the information is organized into bits. These bits can then be used by digital devices and systems including computers.

briefly explain what is net neutrality and why is it important today
Net neutrality also means that ISPs can't charge users access fees for particular websites. ... The goal of net neutrality is to ensure that businesses can compete freely on the internet without having to pay gatekeeper tolls. Without it consumers would look more like advertising segments than an open marketplace.

how is hardware different from sofware?
Answer:
Computer hardware is any physical device used in or with your machine, whereas software is a collection of code installed onto your computer's hard drive. For example, the computer monitor you are using to read this text and the mouse you are using to navigate this web page are computer hardware.
All software utilizes at least one hardware device to operate. For example, a video game, which is software, uses the computer processor (CPU), memory (RAM), hard drive, and video card to run. Word processing software uses the computer processor, memory, and hard drive to create and save documents.
