What is the purpose of the backoff on Ethernet networks?

stellarik [79]

Answer: Please see below as the answer is self-explanatory.

Explanation:

In the original Ethernet standard, IEEE 802.3, the method used to deliver packets within a Ethernet network, is called CSMA/CD, and the acronym includes all the Ethernet features in brief.

Let's explain the different parts of the acronym.

CSMA= Carrier Sense Multiple Access.

This means that when any computer in the network (with no privileges for nobody) has a packet to transmit, it first "listen"if the network is idle. If it is the found condition, deliver the packet, and wait for an acknowledgement.

If past a given time, the ACK is not received, assumes that the packet was lost, due to a collision with another packet coming from another computer (this can happen because the packets don't travel instantaneously from one host to another, so one machine could have started to transmit before the another one could sense this fact).

This process is described by the other part of the acronym:

CD = Collission Detection

In order to avoid this type of problem, before trying to resend the packet, it waits some time, which is called "backoff".

This time increases exponentially each time that it is not possible to send a packet successfully, in order to try to find a moment in which finally the network be clear.

How does the DNS solve the problem of translating domain names like example.com into IP addresses?

TEA [102]

Answer:

DNS translates domain names and hostnames into IP addresses through a basic lookup function. When a user requests a domain name (as in the case of a browser lookup) the computer queries the local DNS server to find the matching IP address. If the local DNS server does not contain the information in it's local database, it contacts the next higher DNS system or the root domain DNS servers (i.e. microsoft.com - if the local system does not know it, it will query the well-known DNS server for the .com domain - which will know where to get the information).

DNS helps the users by not requiring them to remember the IP address of every system them want to connect with. microsoft.com is much easier to remember than 40.82.167.220.

DNS also helps the internet scale through the use of load balancing. Multiple systems can comprise a single web site with the web pages stored on many different machines with multiple IP addresses. When a user requests the microsoft.com website IP, they are given the primary IP of the load balancer sitting in front of the multiple computers. The load balancer will then distribute the traffic to any of the systems that are hosting the web page that are not busy. To the end user it look like they are connecting to a single machine - when in fact they are connecting to one of potentially hundreds of web servers with the same content. As traffic grows on the internet more servers are necessary to handle the additional traffic. DNS helps ensure the end user will connect to the proper web server regardless of the number of web server copies spun up in response to the additional traffic. This allows the capacity to scale as necessary without interruption to the web site.

.Write an if-else statement for the following:

bija089 [108]

Answer:

Solution part of the question:

if(userTickets>5) //compare the value of userTickets with 5.

awardPoints = 10; // assign the 10 value to the award point

else

awardPoints=userTickets;// assign the userticket value to the awardpoint.

Output:

For the input 4 the output is 4.

For the input 5 the output is 5.

For the input 6 the output is 10.

For the input 7 the output is 10.

Explanation:

All the other part of the program is given on the question so here only if-else statement is given on the answer part. Which is pasted at the place of "/* Your solution goes here */" and the user can get the right answer.

In the "if" statement the value of "userTickets" variable is get compared by 5 and if it is greater than 5 than variable "awardpoint" assigns the '10' value.
Otherwise, with the help of "else" statement "userticket" variables value (which is the input value for the program) assign to the "awardpoint" variable.
