Why does the PC send out a broadcast ARP prior to sending the first ping request

1 answer:

5 0

Since the ARP broadcast is utilized to request the MAC address of the Host with the IP address contained in the ARP, the PC needs to know the destination of MAC address before it can produce the frame header for the particular PING requested, before it can send a PING to a host.

Answer:

Will have to run the net start spooler command.

Explanation:

The printer spooler seems to be accountable for overseeing incoming faxes that have been in effect intended for handling by the printer. Whether this device stops operating, your printer won't publish documentation as well as the machine may not notice it either.
To solve these problems, you'll need to run the net start spooler command using the least administrative effort.

Assume inputFile is a Scanner object used to read data from a text file that contains a number of lines. Each line contains an a

anzhelika [568]

Answer:

words.hasNext()

Explanation:

Given the code snippet below:

while (inputFile.hasNextLine()) {
String word = "";
String line = inputFile.nextLine();
Scanner words = new Scanner(line);
while (words.hasNext()) {
word = words.next();
}
System.out.println(word); }
}

We have a inputFile Scanner object that can read data from a text file and we presume the inputFile has read several rows of data from the text file. So long as there is another line of input data available, the outer while loop will keep running. In each outer loop, one line of data will be read and assign to line variable (Line 3). Next, there is another Scanner object, words, which will take the current line of data as input. To get the last word of that line, we can use hasNext() method. This method will always return true if there is another tokens in its input. So the inner while loop will keep running so long as there is a token in current line of data and assign the current token to word variable. The word will hold the last token of current line of data upon exit from the inner loop. Then we can print the output (Line 8) which is the last word of the current line of data.

What would you need to have on your foley stage

You will need many props for your Specific tracks (whatever you see in the film!). It's impossible to say what you will need until you see the picture and as time goes by you will add to your collection (if you have space!) - garbage day in my neighborhood is 'golden day' as I collect some of best props from the stuff people throw out: old bicycles, doors, sinks, wood, metal, desks, etc.
