Answer:

Worm malware

Explanation:

The worm operates destructively as it replicates itself and keeps spreading within a computer or network. It takes advantage of software and security vulnerabilities.

Once a computer or network is infected, worms replicate themselves, therefore using up the computer and network resources. Among others, one of the major missions of worms is to create a backdoor into a network, to be able to enable the attacker to carry out a more devastating attack.

Since worms take advantage of weak security in the Operating system, it is very important to constantly update the security features of the Operating system. Users must be careful of the emails they open and attachments they download.

A major weakness of a lot of file processing systems is that ____.
Gnesinka [82]

They are several weaknesses or disadvantages of file processing systems but the major weakness is data redundancy and inconsistency. By data redundancy, I mean duplication of data. There are no better methods to validate insertion of duplicate data in file systems. Data redundancy can also increase the chance for errors.

Write a flowchart and C code for a program that does the following: Within main(), it asks for the user's annual income. Within
Fiesta28 [93]

Answer:

I am writing a C program:

#include <stdio.h> //to use input output functions

void printIt(double annual_in){ //function printIt

   if(annual_in >90000) //check if the income is greater than 90000

   printf("Congratulations. Doing great!"); //print this message if income value is greater than 90000

   else //if annual income is less than 90000

   printf("You WILL make $50,000, if you keep going"); } //print this message if income value is less than 90000

int main() //start of main() funciton body  

{   double income; //declares a double type variable income to hold annual income value

   printf("Enter annual income: "); //prompts user to enter annual income

   scanf("%lf",&income); //reads income value from user

   printIt(income); } // calls printIt method by passing input income to that function

     

Explanation:

The program is well explained in the comments mentioned with each statement of the program. The flowchart is attached.

First flowchart flow1 has a separate main program flowchart which reads the income and calls printIt function. A second flowchart is of prinIt() method that checks the input income passed by main function and displays the corresponding messages and return.

The second flowchart flow2 is the simple flowchart that simply gives functional description of the C program as flowchart is not where giving function definitions is important. Instead of defining the function printIt separately for this C program, a high-level representation of functional aspects of this program is described in second flowchart while not getting into implementation details.

A queueing system has four crews with three members each. The number of "servers" is:
pentagon [3]

Answer:

The answer is 4.

The number of active servers is four for this four crew queuing system.

Explanation:

 Now what is a queue management system?

As from the name it has some link with queue which means it’s not something used once or twice.

It is a continuous process. In simple words, the number of processes increases and the severs get short and congested on this type of problem this management occurs.

It is always there to solve the problem of congestion the system.

Queuing management is concerned with queuing areas. Where there will a queue this system will be applied. And this queuing system is based on queuing theory.

<u>Now what means by queuing areas? </u>

It’s a place where queues happen.

<u> But what exactly is a queue? </u>

You could say it’s a line of something waiting for services or you can also say it as an application of “demands exceed the supply” problem.

Now consider queuing system where the number of active servers depends upon the the length of the queue.

As the length of the queue increases the number of active servers will increase and if the length of the queue decreases the number of active servers decreases.

On traditional scale the queuing theory, the theory on which this queuing system is based, there are fixed number of servers for each model as 10,25 or 19 servers.  

Now if we see there is a queuing system has four crews with 3 members each.

Each crew will have its own one single active server so, there will be 4 active servers in this queuing system.

Assume the input data is structured as follows: first there is a non-negative integer specifying the number of employee timeshee
Vesna [10]

Answer:

int employees;   //set integer type variable

int a,b;     //set two integer type variable

int wage=0;   //initialize integer type variable

int hours=0;   //initialize integer type vcariable

total=0;    

cin >> employees;    //get input from the user

for (a=1; a<=employees; a++){     //set for loop

cin >> wage;     //get input from the user

for (b=1; b<=5; b++){    //set for loop

cin >> hours;    //get input from the user

total += hours * wage;    //perform multiplication

}

}

Explanation:

Here, we define four integer type variable "a", "b", "wage" "hour" and assign value in "wage" to 0 and "hours" to 0.

Then, we get input from the user in the variable "employees".

Then, we set the for loop and pass the condition inside it we get input from the user in the variable "wage".

Then, again we set the for loop and pass the condition inside it we get input from the user in the variable "hours".

Then, we perform addition and the multiplication.
