Answer:
1.1
1.25
Clock rate A = 0.733 clock rate B
Explanation:
Given the following :
Clock cycle time = 1ns = 10^-9 s
COMPILER A:
Instruction count = 1.0E9
Execution time = 1.1 s
COMPILER B:
Instruction count = 1.2E9
Execution time = 1.5 s
Using the relation :
CPI = [Execution time / (instruction count × cycle time)]
CPI for compiler A :
[1.1 / (10^9 × 10^-9)] = 1.1 / 10^0 = 1.1 / 1 = 1.1
CPI for compiler B:
[1.5 / (1.2 ×10^9 * 10^-9)]
(1.5 / 1.2 * 1) = 1.5 / 1.2 = 1.25
b. Assume the compiled programs run on two different processors. If the execution times on the two processors are the same, how much faster
Since, execution time is the same on both processors
Execution time = [(Instruction count × CPI) / clock rate] ;
[(Instruction count × CPI) / clock rate] A = [(Instruction count × CPI) / clock rate] B
Make clock rate of A the subject of the formula :
(Instruction count A * CPI A * clock rate B) / (instruction count B * CPI B)
= (10^9 * 1.1 * clock rate B / 1.2 × 10^9 * 1.25)
1.1 × 10^9 clock rate B / 1.5 × 10^9
Clock rate A = 0.733 clock rate B
What is the focus of developers interested in the Internet of Things?
A. Converting electrical devices into programmable appliances
O B. Creating specialized software for enterprise systems
C. Creating social networking sites
D. Developing international teleconferencing capabilities
Answer: A. Converting electrical devices into programmable appliances
Explanation:
The focus is on converting electrical devices into programmable appliances. The correct option is A.
What are electrical devices?Devices that functionally rely on electric energy (AC or DC) to power their essential components are known as electric(al) devices (electric motors, transformers, lighting, rechargeable batteries, control electronics).
Electrical energy is received by electrical equipment, which directly convert it into various forms of energy like light, heat, or mechanical energy. For instance, an iron uses electrical energy to create heat that may be used to iron clothing.
Electrical energy is transformed into other forms of energy, such as heat, light, or sound, using electrical devices. To carry out a task, electronic gadgets regulate the flow of electrons.
The goal of Internet of Things developers is to turn electrical equipment into programmable appliances.
Thus, the correct option is A.

The Boffo Balloon Company makes helium balloons. Large balloons cost $13.00 a dozen, medium-sized balloons cost $11.00 a dozen, and small balloons cost $8.60 a dozen. Customer order information includes customer name, quantity ordered, and size. This program should output the customer order information and total sales according to what and how many balloons they have ordered.
Answer:
name = input("Enter customer name: ")
quantity = int(input("Enter quantity: "))
size = input("Enter size [large-medium-small]: ")
if size == "large":
sales = (quantity / 12) * 13
if size == "medium":
sales = (quantity / 12) * 11
if size == "small":
sales = (quantity / 12) * 8.6
print(name + " ordered " + str(quantity) + " " + size + " ballons")
print("Total sales is $" + str(sales))
Explanation:
*The code is in Python.
Ask the user to enter name, quantity, and size
Check the size using if structure. Depending on the size, calculate the sales using the given cost for for a dozen.

Which of the following is not a valid PHP variable:
a. $_tenth,
b. $Tenth,
c. $10th,
d. $tENTH
Why is it not valid?
Answer:
c. $10th
Explanation:
In order to declare or create a valid variable in PHP, there are rules and guidelines to follow, these the following:
1. Valid variable begins with the $ sign.
2. It must begin with a letter or the underscore character only.
3. Valid variable cannot begin with a number after the $ dollar sign.
4. It can only contain alpha-numeric characters and underscores
5. Valid variable name is case-sensitive
Hence, given these rules and guidelines, the correct answer is option C, which after starting with $ sign begins with a number character.

Imagine that you own a small business. Give all reasons why you should buy an ink-jet printer.
Answer:
Follows are the explanation to this question:
Explanation:
It works well with a jet ink printer. Even so, its ink cartridges were pricey. Inkjet printers could be low-cost because you sometimes can buy a basic print for just $30. This is not as durable as inkjet printers, and it provides good quality copies. The inkjet printer may be the right choice if you ever don't print several pages. However, the 30 $printer may want a 20 $cartridge and replenish. Check the monthly duty period for both the costs each tab.
Many people keep time using a 24 hour clock (11 is 11am and 23 is 11pm, 0 is midnight). If it is currently 13 and you set your alarm to go off in 50 hours, it will be 15 (3pm). Write a Python program to solve the general version of the above problem. Your program should first prompt the user for the time now (in hours) and for the number of hours to wait for the alarm, then store those values as type int variables time_now and wait_time respectively, and finally print the time on the 24 hour clock when the alarm will go off.
Answer:
The program written in Python is as follows;
time_now = int(input("Time: "))
wait_time = int(input("Alarm: "))
time_now = time_now + wait_time%24
if time_now < 12:
print(str(time_now)+"am")
else:
time_now = time_now - 12
print(str(time_now)+"pm")
Explanation:
This line prompts user for current time
time_now = int(input("Time: "))
This line prompts user for the alarm hours
wait_time = int(input("Alarm: "))
This line calculates the time of the alarm
time_now = time_now + wait_time%24
The following if statement determines if the time will be am or pm
If the time is less than 12, then the time will be in am
if time_now < 12:
print(str(time_now)+"am")
If otherwise, then the time will be in pm
else:
time_now = time_now - 12
print(str(time_now)+"pm")

Write a program that will simulate a change machine found at cash registers. Input the amount due and amount paid from the keyboard. Tell the user how much change is owed and number of quarters, dimes, nickels, and pennies in change a customer would receive. Pay special attention to roundoff error. Your program should use division and modular division. No if’s or loops may be used. You may assume all change will be between $0 and $.99 Hint: Modular division is a great way to find the remainder of a division. Think about how you can use this to calculate the change that is left over after some coins are given.
Answer:
amount_due = float(input("Enter amount due: "))
amount_paid = float(input("Enter amount paid: "))
change = amount_paid - amount_due
pennies = change * 100
quarters = int(pennies / 25)
pennies %= 25
dimes = int(pennies / 10)
pennies %= 10
nickels = int(pennies / 5)
pennies %= 5
pennies = int(pennies)
print("Your change is $%.2f" % change)
print("Quarters: " + str(quarters) + ", Dimes: " + str(dimes) + ", Nickels: " + str(nickels) + ", Pennies: " + str(pennies))
Explanation:
*The code is in Python.
Ask the user to enter amount due and amount paid
Calculate the change
Convert change to pennies
Find the number of quarters, dimes, nickels in the pennies using division and modular operator. The remaining amount equals the number of pennies
Print the change
Print the number of quarters, dimes, nickels, and pennies
Let me demonstrate calculating the quarters:
Let's say pennies equals 39,
quarters = int(pennies / 25) → int(39/35) → int(1.11) = 1
pennies %= 25 (same as pennies = pennies % 25) → 39 % 25 → 14
