The default setting for a secondary zone's refresh interval is how many minutes

1 answer:

4 0

The default value at which a refresh interval (an interval a sec. server check for zone updates) is 15 minutes.
If this value is increased, the network traffic is reduced. In the eventuality that the refresh interval expires, the secondary zone will contact the primary zone and request it to initiate the zone transfer.

What method of the Math object can be used to return the largest value from the values that are passed to it?

miss Akunina [59]

Answer:

the Math.max() method

Explanation:

The java.lang.* package contains all the essential components needed for a JAVA program which involves numbers and all the operations done on the numericals.

The java.lang.math class contains all the methods needed to perform mathematical operations on numerical values.

All the methods in the question are discussed below with examples.

Math.max() method

java.lang.Math.max(double/ int/ float a, double/ int/ float b)

This method returns the highest value from among the parameters passed to it.

The syntax for the above is

Numbers can be integers, float and double or long. The return type is the same as the parameters.

Two values to be compared are passed as arguments and the higher value of them is returned.

This function also accepts negative integers as parameters.

Math.max(-9, -2);

Gives -2 as the output.

Math.max(0.34, 0.45)

Gives 0.45 as the output.

Math.ceil() method

java.lang.Math.ceil(double/ int/ float a)

This method returns the nearest greater whole number for the given number.

Integer parameter returns an integer number.

Math.ceil(7);

Gives 7 as the output.

Decimal number will return the nearest higher integer.

Math.ceil(8.7);

Gives 9.0 as the output.

Math.ceil(-0.34)

Gives -0 as the output.

Math.pow() method

java.lang.Math.pow(double/ float/ int a, double/ float/ int b)

The above method returns the result of a raise to the power of b.

The first parameter is the base while the second parameter forms the exponent.

Math.pow( 2.3, 4.5 );

This calculates (2.3)^4.5.

Gives 42.44‬ as the output.

Math.pow( 2, 3 );

This calculates the value of 2^3.

Gives 8 as the output.

Math.abs() method

java.lang.Math.abs(double a)

This method returns non-negative value of the numerical parameter passed to it. Absolute of a number does not changes its value but changes the sign of a negative number. It returns the positive or negation of the negative input number.

Math.abs(-0.1234)

Gives 0.1234 as the output.

Math.abs(12.34)

Gives 12.34 as the output.

These methods require java.lang.Math to be imported in the program.

aliina [53]

Haley wickenheiser felt angry after the Bach said the IOC would make a decision in the next month as the IOC says the games will be held no later than summer 2021 but they will still be called the 2020 Tokyo Olympics.

Explanation:

The Tokyo Olympics were postponed until 2021 on Tuesday, ending weeks of speculation that the games could not go ahead as scheduled because of the coronavirus pandemic.
The International Olympic Committee made the decision after speaking with Japanese Prime Minister Shinzo Abe and local organizers.
The IOC said the games will be held not later than summer 2021 but they will still be called the 2020 Tokyo Olympics.
“President Bach said he will agree ‘100%,’ and we agreed to hold the Tokyo Olympics and Paralympics in the summer of 2021 at the latest,” Abe said, saying holding the games next year would be “proof of a victory by human beings against the coronavirus infections.”
The decision came only a few hours after local organizers said the torch relay would start as planned on Thursday.

The definition of network is:

kondaur [170]

$\text{Hello there!}$

Networks were originally used as a government weapon 61 years ago to communicate information such as data and research. However, individual networks were eventually discontinued by the government and made open to the public to use for things such as PAN, LAN, MAN, WAN, SAN, and so on.

Our internet today is capable of communicating with bilions of computers. This is possible due to your modem using radio wave-like speeds to connect to your ISP. Your ISP then connects to a larger network, which is connecting to thousands of other networks. You see, the internet is just a large network of networks that are connected through very fast radiowaves. However, it is not just a single network being used anymore; it's thousands of them. The term, "internet" was used to describe this large selection of networks. In short, B would be incorrect.

The worldwide web is a protocol used by the internet to connect to select websites favourably from whoever's using it. This obviously would not define the network, as this is something that's used by it. Furthermore, A would not be correct.

As described already, the network was a selection of computers used to communicate information to each other. C would not be correct as it states that there is only one computer being used.

$\fbox{Therefore, D would be the correct answer.}$
