_________________ is the logical operator if either conditions is True, then the whole statement is TRUE.

Rus_ich [418]

Answer:

Assuming your using the language python, The 'or' operator

Explanation:

To explain this further, or is used in python to describe another condition whether the first one was true or false. Here is a list of what they all briefly mean:

Object-Oriented Programming allows you to create objects with specific characteristics. Ex. you could have a dog class that describes a dogs name and breed. You can make an instance and call it Max with its breed being a golden retriever etc.

----------------------------------------------------------------------------------------------------------------

Procedures independant code that just has simple instructions

----------------------------------------------------------------------------------------------------------------

Functions like object oriented programing but instead of having attributes it is a block of code that does an action. In python, unless the function is called, however, it won't do anything

----------------------------------------------------------------------------------------------------------------

'or' allows someone to give another condition whether the other conditions were True or False.

hope this helped :D

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.

The input stream of a stack is a list of all the elements we pushed onto the stack, in the order that we pushed them. If the inp

Answer:

Push Z

Push Y

Pop Y

Push X

Pop X

Push W

Push V

Pop V

Push U

Pop U

Pop W

Pop Z

Push T

Push S

Pop S

Push R

Pop R

Pop T

Explanation:

A stack is a term in computer science that defines an abstract data type that acts as a collection of elements. It has two operations which are mainly push and pop.

Push is used in adding elements to the collection, while pop is used in removing elements from the collection.

If the element A has been pushed to the stack, you check if the top element in the pop[] sequence is A or not.

If it is A, you then pop it right, else top of the push[] sequence will be changed and make the sequences invalid.

So, similarly do the same for all the elements and check if the stack is empty or not in the last.

If empty you then print True else print False.
