An administrator wants to restrict access to a particular database based upon a stringent set of requirements. The organization is using a discretionary access control model. The database cannot be written to during a specified period when transactions are being reconciled. What type of restriction might the administrator impose on access to the database

Answers

Answer:

Time of the day and object restrictions

Explanation:

From the question, we understand that the database is not allowed to be accessed at a certain period of time.  

Because this has to do with time (period), the administrator will need to set a time of the day object restriction on the database in order to prevent the users from accessing the database objects

Assume in the for loop header, the range function has the three arguments: range (1, 10, 3), if you were to print out the value of the variable
in the for loop header, what will be printed out? List the values and separate them with a comma.

Answers

Answer:

1, 4, 7

Explanation:

The instruction in the question can be represented as:

for i in range(1,10,3):

   print i

What the above code does is that:

It starts printing the value of i from 1

Increment by 3

Then stop printing at 9 (i.e.. 10 - 1)

So: The sequence is as follows

Print 1

Add 3, to give 4

Print 4

Add 3, to give 7

Print 7

Add 3, to give 10 (10 > 10 - 1).

So, it stops execution.

See the lseek_example.c file. Modify the lseek_example.c, such that it reads from an input file (named "start.txt") and will print to an output file (named "end.txt") every (1+3*i)th character, starting from the 1st character in the input file. In other words, it will print the 1st character, then skip 2 characters and print the 4th one, then skip 2 characters and print the 7th one, and so on.
For instance, for input file:
ABCDEFGHIJKLM
It will output:
ADGJM

// C program to read nth byte of a file and
// copy it to another file using lseek
#include

// Open the file for READ only.
int f_read = open("start.txt", O_RDONLY);
// Open the file for WRITE and READ only.

int count = 0;
while (read(f_read, arr, 1))

Consider two different implementations, M1 and M2, of the same instruction set. There are three classes of instructions (A, B, and C) in the instruction set. M1 has a clock rate of 60MHz and M2 has a clock rate of 80MHz. The average number of cycles of each instruction class and their frequencies (for a typical program) are as follows:
Instruction Class M1-cycles M2-cycles/ Frequency
/instruction class instruction class
A 1 2 50%
B 2 3 20%
C 3 4 30%
a. Calculate the average CPI for each machine, M1 and M2.
b. Calculate the CPU execution time of M1 and M2.

Answers

Explanation:

A.)

we have two machines M1 and M2

cpi stands for clocks per instruction.

to get cpi for machine 1:

= we multiply frequencies with their corresponding M1 cycles and add everything up

50/100 x 1 = 0.5

20/100 x 2 = 0.4

30/100 x 3 = 0.9

CPI for M1 = 0.5 + 0.4 + 0.9 = 1.8

We find CPI for machine 2

we use the same formula we used for 1 above

50/100 x 2 = 1

20/100 x 3 = 0.6

30/100 x 4 = 1.2

CPI for m2 =  1 + 0.6 + 1.2 = 2.8

B.)

CPU execution time for m1 and m2

this is calculated by using the formula;

I * CPI/clock cycle time

execution time for A:

= I * 1.8/60X10⁶

= I x 30 nsec

execution time b:

I x 2.8/80x10⁶

= I x 35 nsec

The child’s game, War, consists of two players each having a deck of cards. For each play, each person turns over the top card in his or her deck. The higher card wins that round of play and the winner takes both cards. The game continues until one person has all the cards and the other has none. Create a program that simulates a modified game of War.
The computer will play both hands, as PlayerOne and PlayerTwo, and, for each round will generate two random numbers and compare them.
If the first number is higher, PlayerOne’s score is increased by 1 and if the second number is higher, PlayerTwo’s score is increased by 1.
If there is a tie, no score is incremented.
When one "player" reaches a score of 10, that player should be deemed the winner and the game ends.
The range of numbers should be 1-13 to simulate the values of cards in the deck.

1. Add the following method to the Point class:
public double distance(Point other)
Returns the distance between the current Point object and the given other Point object. The distance between two points is equal to the square root of the sum of the squares of the differences of their x- and y-coordinates. In other words, the distance between two points (x1, y1) and (x2, y2) can be expressed as the square root of (x2 - x1)2 + (y2 - y1)2. Two points with the same (x, y) coordinates should return a distance of 0.0.
public class Point {
int x;
int y;
// your code goes here
}
2. Create a class called Name that represents a person's name. The class should have fields named firstName representing the person's first name, lastName representing their last name, and middleInitial representing their middle initial (a single character). Your class should contain only fields for now.
3. Add two new methods to the Name class:
public String getNormalOrder()
Returns the person's name in normal order, with the first name followed by the middle initial and last name. For example, if the first name is "John", the middle initial is 'Q', and the last name is "Public", this method returns "John Q. Public".
public String getReverseOrder()
Returns the person's name in reverse order, with the last name preceding the first name and middle initial. For example, if the first name is "John", the middle initial is 'Q', and the last name is "Public", this method returns "Public, John Q.".
4. Add the following method to the Point class:
public int quadrant()
Returns which quadrant of the x/y plane this Point object falls in. Quadrant 1 contains all points whose x and y values are both positive. Quadrant 2 contains all points with negative x but positive y. Quadrant 3 contains all points with negative x and y values. Quadrant 4 contains all points with positive x but negative y. If the point lies directly on the x and/or y axis, return 0.
public class Point {
private int x;
private int y;

// your code goes here
}

Explanation:

The following code is written in Java and creates all of the methods that were requested in the question. There is no main method in any of these classes so they will have to be called from the main method and call one of the objects created method for the code to be tested. (I have tested it and it is working perfectly.)

class Point {

   private int x, y;

   public void Point(int x, int y) {

       this.x = x;

       this.y = y;

   }

   public double distance (Point other) {

      double distance = Math.sqrt(Math.pow((other.x - this.x), 2) + Math.pow((other.y - this.y), 2));

      return distance;

   }

   

   public int quadrant() {

       if (this.x > 0 && this.y > 0) {

           return 1;

       } else if (this.x < 0 && this.y > 0) {

           return 2;

       } else if (this.x < 0 && this.y < 0) {

           return 3;

       } else if (this.x > 0 && this.y < 0) {

           return 4;

       } else {

           return 0;

       }

   }

}

class Name {

   String firstName, lastName;

   char middleInitial;

   

   public String getNormalOrder() {

       String fullName = firstName + " " + middleInitial + " " + lastName;

       return fullName;

Assume the data link protocol used by NDAS has the following associated characteristics:

An 8-bit ASCII code is used. Each frame has a size (length) of 11936 bits. A half-duplex circuit with a speed of 1 million bits per second is used for transmission. There is a 30-millisecond turnaround time on the half-duplex circuit. Each frame contains 20 overhead (non-user-data) bytes. Assume that the probability of a frame requiring retransmission due to error in transmission is 1 percent. A millisecond is one-thousandth of a second. Also, 8 bits = 1 character = 1byte

Fill in the blanks

K= _________ bits per bytes
M=_________ bytes
C= _________ overhead bytes

Answers

Answer:

The transmission speed = 0.278 MB/s

Explanation:

K = 8 bits

M = 11936/8 bits = 1492 bits

transmission rate R = 1000000/ 8 = 125000 bps

overhead bytes C = 20

probability = 0.01

time T = 30 ms = 30 x10^-3 s

The data transmission speed formula = K(M-C)(1-p) / (M/R) + T

 = 8( 1492 - 20)(0.99)/ (1492/125000) + 30 x10^-3

 = 0.278 MB/s

how to learn python ?

Answers

Answer:

See below.

Explanation:

To learn python programming language, first, you have to know the basic. Surely, you may recognize this function namely print()

print(“Hello, World!”) — output as Hello, World!

First, start with familiarizing yourself with basic function such as print. Then step up with arithmetic and declare or assign variable then list.

Here are example of functions:

1.) print(argument) — If argument is a string (word-typed), make sure to use “” or ‘’ or else it’ll output an error and say the argument is not defined.

print(“Hi, Brainly”) will output Hi, Brainly

print(2+3) will output 5

Numerical data or numbers do not necessarily require “ “ or ‘ ‘

print(3+3) will output 6 but print(“3+3”) will output 3+3 which is now a string.

2.) type(argument) - this tells you which data/argument it is. There are

< class ‘str’ > which is string, meaning it contains “ “ or ‘ ‘< class ‘int’ > which is integer< class ‘float’ > which is decimal (20.0 is also considered as float, basically anything that contains decimal is all float type)< class ‘list’ > which is a list. List is something that contains elements within square brackets [ ]

etc.

Make sure you also do print(type(argument)) as well so it will print out the output.

3.) Arithmetic

+ is addition

Ex. print(1+3) will output 4

   2. - is subtraction

Ex. print(5-4) will output 1

   3. * is multiply

Ex. print(4*5) will output 20

   4. ** is exponent

Ex. print(5**2) will output 25

   5. / is division

Ex. print(6/3) will output 2 — sometimes will output the float type 2.0

   6. % is modulo or remainder

Ex. print(7%2) will output 1

4.) Variables

To assign a variable, use =

An example is:

x = 2

y = 5

print(x+y) will output 7

print(type(x)) will output the < class ‘int’ >

These are examples of what you’ll learn in basic of python - remember, programming depends on experience and always focus on it. Keep practicing and searching will improve your skill at python.
