Consider the following code segment, which is intended to set the Boolean variable inRange to true if the integer value num is g
Natasha_Volkova [10]

Answer:

Option d  num = 50, min = 50, max = 50

Explanation:

Given the code segment:

  1. boolean isBigger;
  2. boolean isSmaller;
  3. boolean inRange;
  4. if (num < max)
  5.        {
  6.            isSmaller = true;
  7.        }
  8.        else {
  9.            isSmaller = false;
  10.        }
  11.        if (num > min)
  12.        {
  13.            isBigger = true;
  14.        }
  15.        else {
  16.            isBigger = false;
  17.        }
  18.        if (isBigger == isSmaller) {
  19.            inRange = true;
  20.        } else {
  21.            inRange = false;
  22.        }

If we have num = 50, min = 50 , max = 50,  the condition num < max will be evaluated to false and therefore isSmaller is set to false.

The condition num > min will be evaluated to false as well and therefore isBigger is set to false.

Since isSmaller and isBigger are both false and therefore isBigger == isSmaller will be evaluated to true and set the inRange = true. This has violated the statement that if the integer value num is greater than min value and less than max value, then only set inRange to true. This is because num = 50 is neither greater than min nor less than max, it is supposedly not in range according to the original intention of the code design.

Research the difference between the heart and the brain ???? and say which is most important and why????​
antoniya [11.8K]

Answer:

The brain is more important because the heart would not be able to function without instructions from the brain, which is very important. The brain is what gives orders to the rest of the body to keep everything going.

Sorry if my explanation sounds bad, I'm not great at wording things))

The sender side of rdt3.0 simply ignores (that is, takes no action on) all received packets that are either in error or have the
Rom4ik [11]

Answer:

It might not work efficiently.

Explanation:

The function of the protocol rtd3.0 is to transfer data to a receiver from a sender.

As soon as the receiver received the packet transferred by the sender, we respond acknowledge (Ack) to the sender so that sender can confirm the receiver has gotten it.  

The receiver will not send any acknowledgment if the packet he receives are such that bits contain error or not in order.

After that timeout, the packet will be re-transmitted by the sender.

It is then possible the protocol might seem to be inefficient if a packet is sent many times, because other packets will have to wait to sent until the current packet is sent successfully.

The solution to prevent this kind of issue is to allow for the occurrence of premature timeouts.
