Answer:
FF-FF-FF-FF-FF-FF and 255.255.255.255
Explanation:
FF-FF-FF-FF-FF-FF can be defined as the layer 2 address broadcast which is often used on ethernet frames as well as help to broadcast all equipment due to the fact broadcast is made possible through Ethernet networks in which the Frames are addressed to reach every computer system on a given LAN segment as far as they are addressed to MAC address FF:FF:FF:FF:FF:FF.
255.255. 255.255 can be seen as the layer 3 address which help to address the exact same hosts because it enables the broadcast address of the zero network which is the local network due to the fact that the IP broadcasts are often used by BOOTP and DHCP clients to find and send requests to their respective servers in which a message sent to a broadcast address may be received by all network-attached hosts.
Therefore the Layer 2 and Layer 3 destination addresses which the message contain are FF-FF-FF-FF-FF-FF and 255.255.255.255
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);
The above program in javascript checks to see if the input number is negative or positive using the while loop condition and keeps executing with each input until it gets a negative input
