It dеpеnds οn thе pοrt availability οn thе PC and thе rοutеr οr switch. If thе PC has a sеrial pοrt and a DB9-tο-RJ45 cablе is availablе, it is gеnеrally еasiеr tο cοnnеct tο thе rοutеr οr switch using thе sеrial cοnsοlе pοrt. If thе PC dοеs nοt havе a sеrial pοrt, a third party USB-tο-Sеrial adaptеr can bе usеd. Ciscο switchеs dο nοt havе mini-USB cοnsοlе pοrts, sο cοnnеcting via USB is nοt an οptiοn. If cοnnеcting frеquеntly tο a Ciscο rοutеr that has a Mini USB cοnsοlе pοrt, this can bе thе mοst еffеctivе mеthοd οncе thе Ciscο drivеrs arе installеd, bеcausе nеarly all nеwеr PCs havе USB pοrts.

Answer:

Solution:

The advantages and disadvantages of using the serial console connection compared to the USB console connection to a cisco router or switch Re as follows:

USB stands for Universal Serial Bus. The advantages over serial and parallel connections are several and quite significant. The data transfer rate of a USB port is quite high I don't remember the specifics but it's something like 10MB/sec. Serial ports are significantly slower and while parallel ports are somewhat faster they are still very slow in comparison to a USB port.  The transfer rate is quite miser compared to USB.  

Another great difference is that with serial or parallel devices you must reboot the computer every time you change a device on the port. USB devices are hot-swappable, meaning you can change them out with the computer on, without having to reboot since the system will automatically detect when a device is plugged in (at least this is Micro$oft claims).  

A great advantage is that several devices to a single USB port through a port hub.  

The only disadvantage is in USB devices are limited to a distance of about 7ft from the port. Serial devices can be extended to a much greater distances.

Explanation:

A worm in technical sense is also known as a computer worm which is a self-replicating virus/ malicious content that replicates itself in order to spread to the uninfected PC. They often use components of an OS (operating system) which are automatic and also invisible to an individual. It should be duly noted that it is usual for a computer worm to be observed only when their replication utilizes system content, slowing other tasks at hand.

"Packet switches have multiple links attached to them. For each attached link the packet switch has a/an ____________, which stores packets that the router is about to send into that link."link buffer

access buffer

output buffer

transmission buffer

none of the above

Answers

Answer: Output buffer

Explanation:

Each packet switches contain multiple links which are attached to it and for individually attached link the output buffer basically store packets. Then, the router send these packets into multiple links.

In output buffer, if the packets are transmitted into the links but it finds that the link is busy with the another packet for transmission. Then, that particular packet needs to be wait in output buffer.

Therefore, the output buffer is the correct option.

Write a Comparator that compares String objects by the number of words they contain. Consider any nonwhitespace string of characters to be a word. For example, "hello" comes before "I see", which comes before "You can do it"

Answers

Answer:

import java.util.Scanner;

public class num12 {

   public static void main(String[] args) {

       Scanner in = new Scanner(System.in);

       System.out.println("Enter the first String");

       String word1 = in.nextLine();

       System.out.println("Enter the second String");

       String word2 = in.nextLine();

       System.out.println("Enter the third String");

       String word3 = in.nextLine();

       //Remove all white spaces

        String cword1 = word1.replace(" ","");

       String cword2 = word2.replace(" ","");

       String cword3 = word3.replace(" ","");

       //Comparing the string by their lengths

       if(cword1.length()>cword2.length()&&cword1.length()>cword3.length()){

           System.out.println(word1+" Is the longest");

       }

       else if(cword2.length()>cword1.length()&&cword2.length()>cword3.length()){

           System.out.println(word2+" Is the longest");

       }

       else{

           System.out.println(cword3+" Is the longest");

       }

   }

}

Explanation:

Using Java Programming Language

Use the Scanner Class to obtain the String values from the user

Save them in different variables

Use the replace() method in java to remove white space from any of the string entered

Using if and else statements compare the lengths of the strings (word.length()) returns the length of the word.

Print out the word that is longest

The statement "the living room floor is rectangular" is an example of a(n) assumption . The length and width of the room are examples of known information, which you can obtain as input from the user.

Explanation:

The given question is a Problem statement.

Problem statement can be defined as the brief description of an issue that needs to be focused in order to reach the require goal.

So the parts that a problem statement may have include:

  • facts and figures (assumptions), that are known in the given scenario.
  • data required (solution)to be calculated by focusing on present assumptions (given as input by the user).

So the attributes to be filled into blanks of given statement are assumption, known, input.
