Answer:

B. Use the Report view.

Explanation:

The fastest way to locate a record for updating is to use the report view.

Answer:

This is the correct answer!!! D. Use the search box.

Explanation:

Answer:

As we need to design the FA for the numbers divisible by 3, so we have to take the states as the remainders when we divide the numbers by 3.

Any number when divided by 3, gives remainder either 0 or 1 or 2. And the number gives remainder 0 is divisible by 3.

Let’s take

So now lets count from 0:

Binary 0 = decimal 0 %3 = 0, so goes to state 0.

Binary 1 =decimal 1 %3 = 1, goes to state 1.

Binary 10 = decimal 2 %3 =2, goes to state 2.

Bianary 11 = decimal 3 %3 =0, goes to state 0.

Bianary 100 = decimal 4 %3 =1, goes to state 1.

Bianary 101 = decimal 5 %3 =2, goes to state 2.

And so on.  

So here the state 0 will be the start state and also the final state.

Explanation:

So the FA is {{0,1,2}, {0,1}, δ, 0, {0}}

where δ(0, 0) = 0

           δ(0, 1) = 1

           δ(1, 0) = 2

           δ(1, 1) = 0

           δ(2, 0) = 1

           δ(2, 1) = 2

Answer:

       System.out.println("Too few.");

     }

     else if(numOfCycles > 4){

        System.out.println("Too many.");

     }

     else {

        for(int index = 0; index < numOfCycles; ++index){

        System.out.println((index + 1) + ": Lather and rinse.");

     }

     System.out.println("Done.");

    }

  }

Explanation:

Answer:

a. composition

Explanation:

When an object of one class is a data field in another class, the two classes are related by composition. In particular the containing class is composed using the contained class. For example:

class container {

    contained  c;

    int a;

}

class contained {

    int b;

}

Here the container class is containing an instance of contained class creating a composition relation.

Answer: There are many different types of user interfaces. To decide on the user interface depends entirely on the requirement of the client.

Explanation:

There are different types of interfaces such as command line user interface, graphical user interface, menu based, form based. Therefore to choose among them it depend on the requirement specified by a client. Mostly nowadays GUI is used. to maintain records form based is preferred. For system software CUI is better due to decrease its pressure on the processor. Networking is also both GUI and CUI. So it depend mainly on the type of application developed , client requirements, power consumption based on its dependence on processor power.

Answer:

All 3 are CSS unit sizes which we can use for margins, fonts, borders etc.

Explanation:

CSS has four different unit sizes. These are:

Pixels (px)

Points (pt)

Ems (em)

Percentages(%)

These units are divided into two different groups. They are fixed and relative.

Pixels and points are fixed , whereas em and percentages are relative unit sizes. Relative unit sizes are good when creating scalable layouts.

Ems (em):

An em is a CSS unit that measures the size of a font. Originally, the em was equal to the width of the capital letter M, which is where its name originated.

It stands for "emphemeral unit" which is relative to the current font size.

The "em" is a scalable unit that  is used in web document media. Ems have mobile-device-friendly nature.

Pixels (px):

Pixels are fixed-size units that are used in screen media. One pixel is equal to one dot in computer. The problem with pixel unit is that it is not relative .

Points (pt):

Point values are only for print. A point is a unit of measurement use for real-life ink on paper. Generally, 72pts= 1 inch which is one real-life inch like on  a ruler. Point  is not recommended to use in web pages.

Generally, 1em=16px=12pt=100% if the body size is 100%.

Relative unit sized fonts change and fixed unit sized fonts remain the same.

For example,

body { font-size: 100%}

p{font-size: 16px}

Answer: Daemon-tools package is a group of tools which are present for the observation of the UNIX  service in qmail. The services and saving of the error messages to logs are monitored by these tools. It helps in simplification of the management and makes the process easy.It has data or information of the errors which occur when setting up or execution of daemon-tools on a particular system.

Answer:

2

Explanation:

if-else is the statement that is used for checking the condition and if the condition is True, then execute the statement otherwise not executed.

initially, the value of n1 = 3, n2 = 6, n3 = 2, sumtotal = 4.

after that, if statement checks for the condition.

3 != 4

condition is TRUE, then the statement sumtotal -= n3; will be executed.

write the statement in simple form:

sumtotal = sumtotal - n3;

so, sumtotal = 4-2 = 2.

after that, the program does not check the further and exit the if-else statement.

Therefore, the answer is 2.

Answer: Yes, without the integrity factor there would be no possibility of confidentiality

Explanation: Integrity is the factor that determines that there has been no manipulation or unauthorized access being done int the data . It is a sort of assurance factor that helps us to know the data present is the actual correct data. So, if there is no integrity then confidentiality factor will be a waste . Confidentiality of data is maintained when there is chances of unauthorized access which can only be know id there is integrity present .

a. No we don't agree with the given statement.

The system can't provide integrity without confidentiality. Here confidentiality means it should be concerned with the assets. In the case when confidentiality should be comprised so here we permit non-authorized access to the resource which might result in the modification of the document. And, if this can be done so the motive of integrity should be lost.

Answer:  exit

Explanation:

exit function terminates the calling process without executing the rest of the code.exit function do some cleaning before termination like buffer flushes etc.

exit(0) exits the program without any error message.

syntax:- void exit(int return code)

You have to include stdlib.h header file in c if you want to use exit function.

Answer:

The answer is (b). 1.

Explanation:

In the code there is only 1 base case .

the base case is as following:-

if(n==0)

return 0;

this is the base case.

Base case is the most important statement in the function that uses recursion because without base case the recursion calls will keep on going and we will get a run time error.

You will learn how to decide what information you need, how to divide that information into the appropriate tables and columns, and how those tables relate to each other. You should read this article before you create your first desktop database.

Answer:

No you can not tell that recursion is ever required to solve a problem.

Recursion is required when in the problem, the solution of the input depends on the solution of the subsets of the input.

Iteration is also another form of repetitive approach we follow to solve that kind of problems.

But the difference between recursion and iteration is :

Explanation:

For example in the Fibonacci sequence problem, to find [tex]f_{n}[/tex], we need to compute [tex]f_{n-1}[/tex] and [tex]f_{n-2}[/tex] before that.

                           Fibonacci(n)

                           1. if(n==0 or n==1)

                           2.       return 1.

                           3.else

                           4.      return( Fibonacci(n-1)+Fibonacci(n-1) )

                           Fibonacci(n)

                           1. if(n<=2)

                           2.    result = 1

                           3.     else

                           4. result1 =1 and result2=1.

                           5.      {  result = result1 +result2.

                           6.         result1= result2.

                           7.         result2 = result.

                           8.      }

                           9.  output result.

Answer:

Group policy object can be applied on the OU level.

Explanation:

This whole question is ambiguous  to say the least. Group Policies can be applied the the OU (Lowest level - if you create the OU or group), the Domain and the AD Forest as long as you link the ou to the root of the AD Forest. In other words, if you wish to create a Group Policy, you also need to create an OU that you can lik it to. i.e, you want all managers to bypass the proxy settings, you create the OU, drop all the Managers in there and create the GP and apply it to the OU or group.

Group Policy Objects enable a system administrator to manage multiple users and computers all at once by setting and enforcing key security policies at the Active Directory Forest, Domain, and Organizational Unit level.

Group Policy Objects enable a system administrator to manage multiple users and computers all at once by setting and enforcing key security policies at the Active Directory Forest, Domain, and Organizational Unit level. Active Directory is a directory service provided by Microsoft that allows administrators to manage and organize their network resources, including user accounts and computer systems. Group Policy Objects (GPOs) are used to define and configure various settings and restrictions that apply to users or computers within a specific Active Directory container, such as a domain or organizational unit.

Answer:

no output, it does not print any thing

Explanation:

if-else statement is used to execute the statement after checking the condition if the condition is true, it allows the program to execute the statement otherwise not.

in the code, define the variable with values x = 9, y = 8 and z = 7.

Then, if the statement checks the condition 9 > 9, the condition is false.

So, the program terminates the if statement and executes the next statement but there is no next statement.

the other if-else statement is within the if condition which already terminates.

Therefore, there is no output.

Linear probing

It does a linear search for an empty slot when a collision is identified

Advantages

Easy to implement

It always finds a location if there is one

Disadvantages

When clusters and keys fill most of the array after forming in adjacent slots of the table, the performance deteriorates

Double probing/hashing

The idea here is to make the offset to the next position probed depending on the key value. This is so it can be different for different keys.

Advantages

Good for double number generation

Smaller hash tables can be used.

Disadvantages

As the table fills up, the performance degrades.

Quadratic probing

It is used to resolve collisions in hash tables. It is an open addressing scheme in computer programming.

Advantage

It is more efficient for a closed hash table.

Disadvantage

Has secondary clustering. Two keys have same probe sequence when they hash to the same location.

Answer:

Vector: each vector position holds one

information. If the hashing function applied to a

set of elements determine the information I1,

I2, ..., In, so the vector V [1 ... n] is used to

represent the hash table.

! Vector + Chain List: Vector contains

pointers to lists that represent the

information.

Hashing Function

! The Hashing Function is responsible for generating a

index from a given key.

! Ideally, the function should provide unique indexes for the

set of possible input keys.

! Hashing function is extremely important,

because she is responsible for distributing the information through

Hash table.

The only feature outside the content pane is title bar and thus is not found in content pane.

Answer:

N logN grows faster.

Explanation:

In N1+∈/N logN  logN is the denominator. So this term is constantly getting divided by  logN while in N logN there is no term in the division and for N > 2 log N will be > 1. So N logN will gorw faster. Since ∈ is greater than 0 So the numerator will be greater than N but it will not grow as fast as N logN.

Final answer:

N[tex]^(1+ε)[/tex] / log N grows faster than N log N because exponential growth surpasses logarithmic growth as N increases.

Explanation:

The question asks which function grows faster: N log N or N1+ε / log N, where ε > 0. To determine this, we need to analyze the growth rate of both functions as N becomes very large. In general, any function that includes a term with N raised to a power (in this case N1+ε) will grow faster than a function that involves N multiplied by a logarithmic function (in this case N log N). The reason is that exponential growth (which includes polynomials) surpasses logarithmic growth as N increases. Therefore, N1+ε / log N grows faster than N log N for any ε > 0.

Answer:

Many network and communication protocols require bit stuffing for the following purposes: to avoid the interpretation of data as control information. For example, with six consecutive 1 bits, X.25 uses the bit stuffing,signal the beginning and end of a frame.

High-level Data link control (HDLC) is a bit-oriented protocol for point-to-point and multi-point communication.P/F bits are present in HDLC control field.

So,Yes bit stuffing is necessary in control field.

Answer:

public accessor methods

Explanation:

When applying strict “Private access” level to a component the designer should provide public accessor methods in its class to allow the object to communicate with the outside world. The access level of these services must be public so that they can be accessed by other classes and objects of the outside world.

Below is an example of such a class design in java :-

class MyClass {

private int num; //private class component

public int getNum(){ //public accessor method to allow the object to        communicate with the outside world

 return num;

}

}

Answer:

False

Explanation:

An abstract class is a class declared abstract — it may or may not include abstract techniques. It is not possible to instantiate abstract classes, but they can be sub-classed.

Abstract method declaration

         abstract void moveTo(double X, double Y);

Usually the subclass offers solutions for all of the abstract techniques in its parent class when an abstract class is sub-classed. If not, however, the subclass must be declared abstract as well.

Example

public abstract class GraphicObject {

  // declaring fields

  // declaring non-abstract methods

  abstract void draw();

}

Answer:

for(i=0; i<4; i++)

{

      for(j=0;j<6;j++)

      {

               A[ i ][ j ] = 2* i - 3*j;

      }

}

Explanation:

In this loop for each i = 0,1,2,3 we fill the the corresponding column values. and then move to next i value i.e. row.

Answer:

TRUE

Explanation:

Interrupt Vectors in the Interrupt Vector table represent the address of the Interrupt Service Routine.

Lets consider an example. When we press a key on the keyboard, a hardware interrupt is raised corresponding to keypress event. The control passes to the corresponding Interrupt Vector in the Interrupt Vector table which in turn directs the execution flow to the keyboard interrupt handler.

There is another command whoami it tells the domain name also along with the username.

You have to write all these commands on the command prompt.

Answer:

public static int[] negToZero(int [] theArray){

        int[] newArray = new int[theArray.length];

        for(int i=0;i<theArray.length;i++){

           if(theArray[i]>=0){

               newArray[i]=theArray[i];

           }else{

              newArray[i]=0;

           }

        }

        return newArray;

    }

Explanation:

The function is a block of the statement which performs the special task.

To return the array from the function, you have to define the function with return type array.

like, int[] name(parameter){

}

Then declare the new array with the same size.

Take the for loop for traversing in the array and check the condition for positive numbers by using if-else statement, if the value is positive store in the new array as it is. Otherwise, store the zero in the new array with the same position.

This process repeated until the condition in the for loop is true.

and finally, return the array.
