Answer:

Trap is a software interrupt that occurs when there is a system call, while hardware interrupt occurs when a hardware component needs urgent attention.

Explanation:

Interrupt is an input signal that disrupt the activities of a computer system, giving immediate attention to a hardware or software request.

In trap interrupt, the system activities are stop for a routine kernel mode operation, since it has a higher priority than the user mode. At the end of the interrupt, it switches control to the user mode.

The hardware interrupt is a signal from hardware devices like the input/output devices, storage and even peripheral devices that draws an immediate attention of the processor, stopping and saving other activities and executing the event with an interrupt handler.

Problem 1 Calculating the tip when you go to a restaurant is not difficult, but your restaurant wants to suggest a tip according
DIA [1.3K]

Answer:

bill = float(input("Enter the bill amount: "))

rating = int(input("Choose a rating: 1 = Totally satisfied, 2 = Satisfied, 3 = Dissatisfied.: "))

if rating is 1:

   tip = bill * 0.2

elif rating is 2:

   tip = bill * 0.15

elif rating is 3:

   tip = bill * 0.1

print("The rating is: " + str(rating))

print("The tip is: $%.2f" % (tip))

Explanation:

*The code is in Python

- Ask the user for the <em>bill</em> and <em>rating</em>

- Depending on the <em>rating</em>, calculate the <em>tip</em> using <u>if else</u> statement i.e. If the rating is chosen as 1, calculate the tip by taking 20 percent of the bill.

- Print the <em>rating</em> and the <em>tip</em>

Because filling a pool/pond with water requires much more water than normal usage, your local city charges a special rate of $0.
nevsk [136]

Answer:

In C:

#include <stdio.h>

int main(){

   float length, width, depth,poolvolume,watervolume,charges;

   printf("Length (feet) : ");    scanf("%f",&length);

   printf("Width (feet) : ");    scanf("%f",&width);

   printf("Depth (feet) : ");    scanf("%f",&depth);

   poolvolume = length * width* depth;

   watervolume = length * width* (12 * depth - 3)/12;

   charges = 100 + 0.77 * watervolume;

   printf("Invoice");

   printf("\nVolume of the pool: %.2f",poolvolume);

   printf("\nAmount of the water needed: %.2f",watervolume);

   printf("\nCost: $%.2f",charges);

   printf("\nLength: %.2f",length);

   printf("\nWidth: %.2f",width);

   printf("\nDepth: %.2f",depth);

   printf("\nMr. Royal [Replace with your name] ");

   return 0;}

Explanation:

This declares the pool dimensions, the pool volume, the water volume and the charges as float    

float length, width, depth,poolvolume,watervolume,charges;

This gets input for length

   printf("Length (feet) : ");    scanf("%f",&length);

This gets input for width

   printf("Width (feet) : ");    scanf("%f",&width);

This gets input for depth

   printf("Depth (feet) : ");    scanf("%f",&depth);

This calculates the pool volume

   poolvolume = length * width* depth;

This calculates the amount of water needed

   watervolume = length * width* (12 * depth - 3)/12;

This calculates the charges

   charges = 100 + 0.77 * watervolume;

This prints the heading Invoice

printf("Invoice");

This prints the volume of the pool

   printf("\nVolume of the pool: %.2f",poolvolume);

This prints the amount of water needed

   printf("\nAmount of the water needed: %.2f",watervolume);

This prints the total charges

   printf("\nCost: $%.2f",charges);

This prints the inputted length

   printf("\nLength: %.2f",length);

This prints the inputted width

   printf("\nWidth: %.2f",width);

This prints the inputted depth

   printf("\nDepth: %.2f",depth);

This prints the name of the programmer

   printf("\nMr. Royal [Replace with your name] ");

   return 0;}

PilotLPTM [1.2K]

Complete Question:

Firewall implementation and design for an enterprise can be a daunting task. Choices made early in the design process can have far-reaching security implications for years to come. Which of the following firewall architecture is designed to host servers that offer public services?

a) Bastion Host

b) Screened subnet

c) Screened host

d)  Screened

Answer:

b) Screened subnet

Explanation:

In Computer science, Firewall implementation and design for an enterprise can be a daunting task. Choices made early in the design process can have far-reaching security implications for years to come.

Screened subnet firewall architecture is designed to host servers that offer public services.

In network security and management, one of the network architecture used by network engineers for the prevention of unauthorized access of data on a computer is a screened subnet. A screened subnet can be defined as a network architecture that uses a single firewall with three screening routers as a firewall.

<em>A screened subnet is also known as a triple-homed firewall, this is because it has three (3) network interfaces;</em>

1. Interface 1: it is known as the external or access router, which is a public interface and connects to the global internet.

2. Interface 2: it is known as the demilitarized zone or perimeter network, which acts as a buffer and hosted public servers (bastions host) are attached herein.

3. Interface 3: it is known as the internal router, which is a subnet that connects to an intranet.

<em>The screened subnet when properly configured helps to prevent access to the internal network or intranet. </em>
