An operating system that allows a single user to perform only one task at a time is called a Single-User Single-Tasking Operating System. Functions like printing a document, downloading images, etc., can be performed only one at a time. Examples include MS-DOS, Palm OS, etc.
Advantage: This operating system occupies less space in memory.
Disadvantage: It can perform only a single task at a time.
There are four types of operating systems −
Real-time operating system
Single-User/Single-Tasking operating system
Single-User/Multitasking operating system
Multi-User/Multitasking operating system
Real-time operating system is designed to run real-time applications. It can be both single- and multi-tasking. Examples include Abbasi, AMX RTOS, etc.
An operating system that allows a single user to perform more than one task at a time is called Single-User Multitasking Operating System. Examples include Microsoft Windows and Macintosh OS.
It is an operating system that permits several users to utilize the programs that are concurrently running on a single network server. The single network server is termed as "Terminal server". "Terminal client" is a software that supports user sessions. Examples include UNIX, MVS, etc.
In this chapter, you learned that although a double and a decimal both hold floating-point numbers, a double can hold a larger value.
Write a C# program named DoubleDecimalTest that declares and displays two variables—a double and a decimal.
Answer:
The DoubleDecimalTest class is as follows:
using System;
class DoubleDecimalTest {
static void Main() {
double doubleNum = 173737388856632566321737373676D;
decimal decimalNum = 173737388856632566321737373676M;
Console.WriteLine(doubleNum);
Console.WriteLine(decimalNum);
}
}
Explanation:
Given
See attachment for complete question
Required
Program to test double and decimal variables in C#
This declares and initializes double variable doubleNum
double doubleNum = 173737388856632566321737373676D;
This declares and initializes double variable decimalNum (using the same value as doubleNum)
decimal decimalNum = 173737388856632566321737373676M;
This prints doubleNum
Console.WriteLine(doubleNum);
This prints decimalNum
Console.WriteLine(decimalNum);
As stated in the question, the above program will fail to compile because the decimal value is out of range.
To ensure that the program runs well, it's either the decimal value is reduced to within its range or it is comment out of the program.

The basic objective of the web server is to store, process and deliver web pages to the users.
FTP server is to allow users to upload and download files. An FTP server is a computer that has a file transfer protocol (FTP) address and is dedicated to receiving an FTP connection. FTP is a protocol used to transfer files via the internet between a server (sender) and a client (receiver)
pop provides access via an Internet Protocol (IP) network for a user client application to a mailbox (maildrop) maintained on a mail server
proxy server is a system that isolates internal clients from the servers by downloading and storing files on behalf of the clients. it intercepts requests for web-based or other resources that come from
The clone() method expects no arguments when called, and returns an exact copy of the type of bag on which it is called.
Answer:
true
Explanation:
This statement is true. This is a method found in the Java programming language and is basically used to create an exact copy of the object that it is being called on. For example, in the code provided below the first line is creating a new object from the Cars class and naming it car1. The second line is creating an exact copy of car1 and saving it as a new object called car2. Notice how the clone() method is being called on the object that we want to copy which in this case is car1.
Cars car1 = new Cars();
Cars car2 = (Cars) car1.clone();

g Write a program that keeps asking the user for new values to be added to a list until the user enters 'exit' ('exit' should NOT be added to the list). These values entered by the user are added to a list we call 'initial_list'. Then write a function that takes this initial_list as input and returns another list with 3 copies of every value in the initial_list. Finally, inside main(), print out all of the values in the new list. For example: Input: Enter value to be added to list: a Enter value to be added to list: b Enter value to be added to list: c Enter value to be added to list: exit Output: a b c a b c a b c Note how 'exit' is NOT added to the list. Also, your program needs to be able to handle any variation of 'exit' such as 'Exit', 'EXIT' etc. and treat them all as 'exit'.
Answer:
Following are the code to the given question:
def list_function(initial_list):#defining a method list_function that takes list in parameter
l = initial_list*3#defining l that multiple the list by 3
return l#return list
def main(): #defining main method
initial_list = []#defining an empty list
while True:#defining while loop
i = input("Enter value to be added to list: ")#defining i variable that input list value
i = i.rstrip()#use rstrip method
if i.lower() == "exit" and "EXIT" and "Exit":#defining if block that checks list value is in lower case
break#use break keyword
initial_list.append(i)#use list that adds input value
l = list_function(initial_list)#defining l variable that calls the list_function method
for i in l:#defining for loop that print list items
print(i)#print value
main()
Output:
Please find the attached file.
Explanation:
In this code, a method "list_function" is declared that takes list "initial_list" in parameter and defines "l" variable that multiple the list by 3 and return its list value.
In the main method an empty list "initial_list" is declared that defines a while loop that input list value and use rstrip method and define and if block that checks list value is in lower case and pass into the method and use for loop to prints its values.

Countdown until matching digits Write a program that takes in an integer in the range 11-100 as input. The output is a countdown starting from the integer, and stopping when both output digits are identical. Ex: If the input is the output is 93 92 91 90 89 88 Ex: If the input is 11 the output is 11 Ex: If the input is 9 or any number not between 11 and 100 (inclusive), the output is: Input must be 11-100 For coding simplicity, follow each output number by a space, even the last one. Use a while loop. Compare the digits do not write a large if-else for all possible same-digit numbers (11,22,33...99), as that approach would be cumbersome for larger ranges. 29999.1122120 LAB ACTIVITY 4.13.1: LAB: Countdown until matching digits 7/10 main.c Load default template... 1 include 2 3 int main() 4 int n, i: 5 scanf("%d", &n); if (n < 20 Il n98) { 7 printf("%d",n); } else { i-n: 1e while (1) printf("%d", 1); if (icie - i/10) 13 14 15 16 17 } 18 printf("\n"); 19 return : 20 ) 12 break; Latest submission - 11:16 PM on 02/05/21 Total score: 7/10 Only show failing tests Download this submission 1: Compare output A 3/3 Input Your output 93 92 91 90 89 88 2: Compare Output A Input 11 Your output 11 3: Compare output a 3/3 Input 20 Your output 20 19 18 17 16 15 14 13 12 11 4: Compare output A 0/2 Output differs.

Answer:
The program in C is as follows:
#include <stdio.h>
int main(){
int n;
scanf("%d", &n);
if(n<11 || n>100){
printf("Input must be between 11 - 100"); }
else{
while(n%11 != 0){
printf("%d ", n);
n--; }
printf("%d ", n); }
return 0;
}
Explanation:
The existing template can not be used. So, I design the program from scratch.
This declares the number n, as integer
int n;
This gets input for n
scanf("%d", &n);
This checks if input is within range (11 - 100, inclusive)
if(n<11 || n>100){
The following prompt is printed if the number is out of range
printf("Input must be between 11 - 100"); }
else{
If input is within range, the countdown is printed
while(n%11 != 0){ ----This checks if the digits are identical using modulus 11
Print the digit
printf("%d ", n);
Decrement by 1
n--; }
This prints the last expected output
printf("%d ", n); }

Conduct research to determine the best network design to ensure security of internal access while retaining public website availability.
Answer:
There are many benefits to be gained from network segmentation, of which security is one of the most important. Having a totally flat and open network is a major risk. Network segmentation improves security by limiting access to resources to specific groups of individuals within the organization and makes unauthorized access more difficult. In the event of a system compromise, an attacker or unauthorized individual would only have access to resources on the same subnet. If access to certain databases in the data center must be given to a third party, by segmenting the network you can easily limit the resources that can be accessed, it also provides greater security against internal threats.
Explanation:
The best method in network security to prevent intrusion are:
Understand and use OSI Model. Know the types of Network Devices. Know Network Defenses. Separate your Network. How can I improve security through network design?In the above case, the things to do is that one needs to focus on these areas for a a good network design. They are:
