Would you prefer to use an integrated router, switch, and firewall configuration for a home network, or would you prefer to operate them as separate systems

Answers

Answer:

I would prefer to use an integrated router, switch, and firewall configuration for a home network instead of operating my home devices as separate systems.

Explanation:

Operating your home devices as separate systems does not offer the required good service in information sharing.  To share the internet connection among the home devices, thereby making it cheaper for family members to access the internet with one  Internet Service Provider (ISP)  account rather than multiple accounts, a home network is required. A home network will always require a network firewall to protect the internal/private LAN from outside attack and to prevent important data from leaking out to the outside world.

Which of the following restricts the ability for individuals to reveal information present in some part of the database?

a. Access Control
b. Inference Control
c. Flow Control
d. Encyption

Answers

Answer:

it would have to be flow control which would be C.

Explanation:

Flow Control is restricts the ability for individuals to reveal information present in some part of the database. Hence, option C is correct.

What is Flow Control?

The management of data flow between computers, devices, or network nodes is known as flow control. This allows the data to be processed at an effective rate. Data overflow, which occurs when a device receives too much data before it can handle it, results in data loss or retransmission.

A design concern at the data link layer is flow control. It is a method that typically monitors the correct data flow from sender to recipient. It is very important because it allows the transmitter to convey data or information at a very quick rate, which allows the receiver to receive it and process it.

The amount of data transmitted to the receiver side without any acknowledgement is dealt with by flow control.

Thus, option C is correct.

Given an array of n distinct integers sorted in ascending order, write a function that returns a Fixed Point in the array, if there is any Fixed Point present in array, else returns -1. Fixed Point in an array is an index i such that arr[i] is equal to i. Note that integers in array can be negative. Examples: #include using namespace std; void removeDivByFive(int *arr,int& size) { int index=0; for(int i=0;i

Answers

Answer:

The function is as follows:

int returnsFixed(int arr [],int n){

   int retVal = -1;

   for(int i = 0; i<n;i++){

       if(i == arr[i]){

           retVal = i;

           break;

       }

   }

   return retVal;

}

Explanation:

This defines the functionl it receives the array and the length of the array

int returnsFixed(int arr [],int n){

This initializes the return value to -1

   int retVal = -1;

This iterates through the array

   for(int i = 0; i<n;i++){

This checks if i equals arr[i]

       if(i == arr[i]){

If yes, the return value (i.e. the fixed point) is set to i

           retVal = i;

And the code is exited

           break;

       } This ends the if condition

   } This ends the iteration

This returns the calculated fixed point

   return retVal;

}

Loop takes only positive numbers and terminates once it encounters a negative numbers.

Answer and Explanation:

Using javascript:

Var positiveInt= window.prompt("insert positive integer");

While(positiveInt>=0){

Alert("a positive integer");

Var positiveInt= window.prompt("insert positive integer");

}

Or we use the do...while loop

Var positiveInt= window.prompt("insert positive integer");

do{

Var positiveInt= window.prompt("insert positive integer");

While (positiveInt>=0);
