Answer:

Lack of global control.

Explanation:

An operating system is a system software pre-installed on a computing device to manage or control software application, computer hardware and user processes.

This ultimately implies that, an operating system acts as an interface or intermediary between the computer end user and the hardware portion of the computer system (computer hardware) in the processing and execution of instructions.

Some examples of an operating system on computers are QNX, Linux, OpenVMS, MacOS, Microsoft windows, IBM, Solaris, VM etc.

There are different types of operating systems (OS) used for specific purposes and these are;

1. Batch Operating System.

2. Multitasking/Time Sharing OS.

3. Multiprocessing OS.

4. Single User OS.

5. Mobile OS.

6. Real Time OS .

7. Distributed OS.

8. Network OS.

A network operating system (NOS) can be defined as specialized computer operating system that are designed primarily for use on network devices such as routers, switches, workstations, which are mainly connected to a local area network.

Generally, the biggest limitation of a network operating system (NOS) is lack of global in terms of memory, process, device, and file management.

How to check if your computer has bluetooth?

Lelu [443]

Assuming you're running Windows, click the start button, and then search for "Device Manager" (or open CMD or PowerShell and type devmgmt.msc). Look at the list of devices. If Bluetooth is there, you have it; if it's not there, you don't.

the development of modern computer system have been evolutionary, discuss this phenomena and further explain how current trends

Volgvan

Answer: Why are there so many of these?

The modern computer system has been evolutionary. Modern computers have allowed for us to complete hard tasks rather easily. With modern computers, we are able to calculate advanced equations with the click of a button. Trends in computing like RTX can rapidly improve performance, rendering, and tons of other graphical heavy actions. In September of 2018, we got the first RTX card, now in 2021, RTX has become exponentially better than what it was in 2018. With the modern computers comes quantum computers. Quantum computing is estimated to be 100 million times faster than any modern computer. IBM, the company to make the first computer stated that we are in the decade of quantum computing. And who knows? Maybe quantum computing will come sooner rather than later.

Explanation:

You probably should modify this a little so you don't get in trouble. I researched each topic I put into this for about an hour so I hope this is what you need. If it isn't, please don't hesitate to tell me what I didn't add or what went wrong.

Have a good day :)

ArbitrLikvidat [17]

The option that is not a type of spoofing is creating a fake website for a well-known business.

<h3>What is email spoofing?</h3>

Email spoofing is known to be a method that is often used in spam and other forms of phishing attacks. This is often done to trick computer users to see that a message originate from a person or firm that they know.

Conclusively, The option that is not a type of spoofing is creating a fake website for a well-known business as it is not what spoofing is all about.

write a program to evaluate the following postfix expression. the value of each variable must be asked from the user during the

ikadub [295]

In this exercise we have to use the knowledge of computational language in C++ to write a code that program to evaluate the following postfix expression. the value of each variable must be asked from the user during the execution time.

<h3>Writting the code:</h3>

#include <bits/stdc++.h>

using namespace std;

// CREATED A CLASS STACK

class Stack

{

public:

int top;

unsigned sz;

int* ar;

};

// VARIOUS STACK FUNCTIONS

Stack* makeStack( unsigned sz )

{

Stack* stack = new Stack();

// BASE CONDITION

if (!stack) return NULL;

stack->top = -1;

stack->sz = sz;

stack->ar = new int[(stack->sz * sizeof(int))];

if (!stack->ar) return NULL;

// RETURNING THE STACK

return stack;

}

// CHECKING IF THE STACK IS EMPTY

int isEmpty(Stack* stack)

{

return stack->top == -1 ;

}

// CHECKING THE TOP OF THE STACK

int whatAtTop(Stack* stack)

{

return stack->ar[stack->top];

}

// POPPING OUT OF A STACK

int pop(Stack* stack)

{

if (!isEmpty(stack))

return stack->ar[stack->top--] ;

return '$';

}

// PUSHING IN THE STACK

void push(Stack* stack, int op)

{

stack->ar[++stack->top] = op;

}

// EVALUATING POSTFIX STARTS HERE

int postfixEvaluator(string res)

{

// CREATING STACK

Stack* stack = makeStack(res.length());

int i;

// BASE CONDITION

if (!stack) return -1;

for (i = 0; res[i]; ++i)

{

// CHECK FOR SPACES

if (res[i] == ' ')continue;

// CHECK FOR THE DIGIT

else if (isdigit(res[i]))

{

int N = 0;

// EXTRACT THE NUMBER OUT OF STACK

while (isdigit(res[i]))

{

N = N * 10 + (int)(res[i] - '0');

i++;

}

i--;

// PUSH THE NUMBER IN STACK

push(stack, N);

}

// POPPING AND ARITHMETIC OPERATIONS

else

{

int pos1 = pop(stack);

int pos2 = pop(stack);

switch (res[i])

{

case '+': push(stack, pos2 + pos1); break;

case '-': push(stack, pos2 - pos1); break;

case '*': push(stack, pos2 * pos1); break;

case '/': push(stack, pos2 / pos1); break;

}

return pop(stack);

}

// MAIN CODE

int main()

{

string tes;

getline(cin, tes);

string tmp = "";

string res = "";

for (int i = 0; i < tes.length(); i++) {

if (tes[i] <= 'z' and tes[i] >= 'a') {

tmp += tes[i];

} else if (tes[i] == ' ' and (tes[i - 1] <= 'z' and tes[i - 1] >= 'a')) {

cout << "Enter the value of " << tmp << ": ";

int x; cin >> x;

res += (to_string(x));

res += ' ';

tmp = "";

} else {

res += tes[i];

}

cout << "\nThe postfix expression is : " << res;

cout << "\nThe result is : " << postfixEvaluator(res);

return 0;

}
