9. Which of the following is the
leading use of computer?
Complete Question:
What is the leading use of computers?
Group of answer choices.
a. web surfing.
b. email, texting, and social networking.
c. e-shopping.
d. word processing.
e. management of finances.
Answer:
b. email, texting, and social networking.
Explanation:
Communication can be defined as a process which typically involves the transfer of information from one person (sender) to another (recipient), through the use of semiotics, symbols and signs that are mutually understood by both parties. One of the most widely used communication channel or medium is an e-mail (electronic mail).
An e-mail is an acronym for electronic mail and it is a software application or program designed to let users send texts and multimedia messages over the internet.
Also, social media platforms (social network) serves as an effective communication channel for the dissemination of information in real-time from one person to another person within or in a different location. Both email and social networking involves texting and are mainly done on computer.
Hence, the leading use of computer is email, texting, and social networking.
how to learn python ?
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 additionEx. 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.

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.
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

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.

The computer scientists Richard Conway and David Gries once wrote: The absence of error messages during translation of a computer program is only a necessary and not a sufficient condition for reasonable [program] correctness. Rewrite this statement without using the words necessary or sufficient.
Answer:
A computer program is not reasonably correct if it has no error messages during translation.
Explanation:
First, we need to understand what the statement means, and we also need to identify the keywords.
The statement means that, when a program does not show up error during translation; this does not mean that the program is correct
Having said that:
We can replace some keywords as follows:
absence of error messages := no error messages
Return a formatted string with numbers The function below takes three numerical inputs: num1, num2, and num3. Implement it to return a formatted string with an underscore between the first two numbers and space, exclamation point, and another space between the second and third number. For example, if the inputs are 1, 2, and 3, then the function should return the string '1_2 ! 3'.
Answer:
In Python:
def ret_formatted(num1,num2,num3):
result = str(num1)+"_"+str(num2)+" ! "+str(num3)
return result
Explanation:
This defines the function
def ret_formatted(num1,num2,num3):
This generates the output string
result = str(num1)+"_"+str(num2)+" ! "+str(num3)
This returns the result string
return result

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
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
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.
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

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
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

A database management system (DBMS) can be defined as a collection of software applications that typically enables computer users to create, store, modify, retrieve and manage data or informations in a database. Generally, it allows computer users to efficiently retrieve and manage their data with an appropriate level of security.
In this scenario, The director of security at an organization has begun reviewing vulnerability scanner results and notices a wide range of vulnerabilities scattered across the company. Most systems appear to have OS patches applied on a consistent basis but there is a large variety of best practices that do not appear to be in place. Thus, to ensure all systems are adhering to common security standards a Network vulnerability database, which typically comprises of security-related software errors, names of software, misconfigurations, impact metrics, and security checklist references should be used.
Basically, the Network vulnerability database collects, maintain and share information about various security-related vulnerabilities on computer systems and software programs.
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
}
Answer:
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.)

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;
}
}
}
