Answer:

No, Only the value between 100 and 200 can not test the code correctly.
This code snippet ensures that the cost value is between 100 and 200.

Explanation:

The above code has three condition test- if, else-if and else.
The first condition is true for the value which is a minimum of 100.
The else if condition is true for the value which is maximum from 200.
Then the else condition is used when the if and else if condition is false.
when the user gives the value between 100 and 200 then it will test that the value lies between 100 or 200.
To test the whole scenario there must be one value is less than 100 and greater than 200.

Answer:

Ethernet cables, Network Adapters, Modem, Routers, Switches.

Explanation:

The devices that are required in setting up a wired network for the 5 computer comprises of the following devices

Ethernet Cables
Network Adapters
Modem/Router
Network Switch

Ethernet cables: They are called network cables or RJ-45 cables used to in connecting two or more computers together. it has different categories called, the untwisted pair and twisted pair Ethernet, with a speed from 10-1000

Network Adapters : This adapters allows a computer device to connect and interface with a network computer

Modem/Routers : A router is a device that that sits in the middle between your local computers and modems. it takes receives information or gets information from the modem and delivers it to the computer

Network switch: it connects more than two computers together to a network and share data among themselves and other devices on the network

Write a program that defines a type for a structure that stores information on a student in ENG EK 125. Declare two variables to

Mashcka [7]

Answer:

Following are the program in the C Programming Language.

#include<stdio.h> //header file

#include<string.h> //header file

struct student//creating structure

{

//set integer variables

int marks;

int roll;

};

//define function

void initial(struct student *stu)

{

//set integer type variables

int marks=420;

int roll_no=45,i;

stu->marks=marks;//assigning the values

stu->roll=roll_no;//assigning the values

}

//define main method to call the function

int main()

{

struct student stu;

initial(&stu);//calling the function

printf("Total marks : %d\n",stu.marks); //print output

printf("Roll No. : %d\n",stu.roll); //print output

return 0;

}

Output:

Total marks : 420

Roll No. : 45

Explanation:

Here, we define the structure "student" with a struct keyword for creating a structure.

inside the structure, we set two integer type variable "marks", "roll".

Then, we define a function "initial()" and pass an argument in the parameter of the function.

inside the function, we set two integer type variable "marks", "roll_no" and assign the value in the variable "marks" to 420 and variable "roll_no" to 45.
Assign the value in the structure's integer variables from the function's variable.

Finally, we set the main method inside it we call the function "initial()" and pass the value and then, we print the output with message.

A computer has 4 GB of RAM of which the operating system occupies 512 MB. The processes are all 256 MB (for simplicity) and have

Afina-wow [57]

Answer:

$1-p^{14} = 0.99$

$p^{14}= 0.01$

$p =(0.01)^{1/14}= 0.720$

So then the value of the maximum I/O wait that can be tolerated is 0.720 or 72 %

Explanation:

Previous concepts

Input/output operations per second (IOPS, pronounced eye-ops) "is an input/output performance measurement used to characterize computer storage devices like hard disk drives (HDD)"

Solution to the problem

For this case since we have 4GB, but 512 MB are destinated to the operating system, we can begin finding the available RAM like this:

Available = 4096 MB - 512 MB = 3584 MB

Now we can find the maximum simultaneous process than can use with this:

$\frac{3584 MB}{256 MB/proc}= 14 processes$

And then we can find the maximum wait I/O that can be tolerated with the following formula:

$1- p^{14}= rate$

The expeonent for p = 14 since we got 14 simultaneous processes, and the rate for this case would be 99% or 0.99, if we solve for p we got:

$1-p^{14} = 0.99$

$p^{14}= 0.01$

$p =(0.01)^{1/14}= 0.720$

So then the value of the maximum I/O wait that can be tolerated is 0.720 or 72 %

Answer: Vulnerability of

Explanation:

The network administrator was able to identify that virus before it led to denial of service to users. Since it has been discovered, it is no longer a threat as measures will be taken to eliminate it. But a virus that was successful uploaded shows how vulnerable the system is or how bad the security protections put in place are. Steps has to be taken to ensure it does not reoccur.
