Consider a hypothetical hard drive that has 400,000 cylinders, 8 heads, and 128 sectors per track. Demonstrate, in writing, how you would calculate the total capacity of this drive. Assume a sector size of 512 bytes and express your answer in GBytes, to the nearest whole GByte, as defined in computer Science.

Answers

Answer 1

Answer:

The approximately capacity of a hard disk drive is 195 GB

Explanation:

sector = 512 B

Sector per track = 128 = 64 KB

cylinder = 8 * 128 (512 KB)

cylinders = 400,000 * 512 KB = 195.3 GB

Most networking media send data using _____ in which data is represented by only two discrete states: 0s and 1s.

A. digital signals

B. contiguous signals

C. ramp signals

D. exponential signals

Answers

Answer:

i think digital signals

Explanation:

A digital signal is a signal that is being used to represent data as a sequence of discrete values; at any given time it can only take on one of a finite number of values.[1][2][3] This contrasts with an analog signal, which represents continuous values; at any given time it represents a real number within a continuous range of values.

Answer: A) Digital signals

Explanation:

Digital signal is a signal that helps in describing about the data in sequential manner in form discrete bands or binary values. The electrical signal containing data is converted into bits that can be represented through two digital values i.e. 0s and 1s.Other options are incorrect because contiguous signal is regular adjacent signal. Ramp signal is represented as increment in magnitude with timeExponential signal is based on sine and cosine signal that is two real time signal.Thus, the correct option is option(A).

Function prototypes and function definitions look similar because they have the same function heading. In a function prototype the heading is followed by a ___, whereas in a function definition the heading is followed by a ___.

Answers

Answer:

In a function prototype the heading is followed by a semicolon, whereas in a function definition the heading is followed by a function block.

Explanation:

As the function prototype only declares the function and the function definition defines the operations in the function.

e.g:

add(int x, int y);  is the prototype

add(int x, int y)

{

     int sum;

     sum [tex]=[/tex] x[tex]+[/tex]y;

}    is the function definition.

Write Python code that prompts the user to enter his or her favorite color and assigns the user’s input to a variable named color.

Answers

Answer:

hope it helps Good luck

Explanation:

color = input("Enter your favorite color: ")

To prompt the user for their favorite color in Python, use the input function and assign the result to the variable 'color'. This demonstrates user input handling and variable assignment, fundamental programming concepts.

To prompt a user to enter their favorite color and assign their input to a variable named color, you can use the following Python code:

color = input('Please enter your favorite color: ')

This line of code uses the input function to display a message to the user, asking them to enter their favorite color. Whatever the user types in response to this prompt is then stored in the variable color.

In programming with Python, entering data through prompts is a common task. This process illustrates how variables can store user input for later use in the program. As you continue to learn Python, you will become familiar with how to differentiate between reserved words and variable names, as modern text editors will often provide visual cues, such as color-coding, to help you differentiate them.

What is the difference between an HTTP POST and an HTTP GET? Give an example of when each would be used ?

Answers

Difference:

An HTTP POST request is used to add new information to a server so it can be stored, and an HTTP GET request is used to retrieve stored information from a server.

Usage Examples:

Let's say you run a web server dedicated to storing football game scores.

A computer at a game that just finished may use an HTTP POST request to send the final score to your web server so you can store it.

Someone at home may be viewing a website for sports scores.  That website's server may send an HTTP GET request to your server asking for the final score of a specific game, and your server would provide that information.

Write a C++ program that prompt the user to enter the coordinate of two points (x1, y1) and (x2,y2), and displays the slope of the line that connects the two points.

Answers

Answer:

#include<iostream>

using namespace std;

int main(){

   float x1,x2;

   float y1,y2;

   float slope;

   cout<<"Enter the value of first point(x1,y1): ";

   cin>>x1>>y1;

   cout<<"\nEnter the value of second point(x2,y2): ";

   cin>>x2>>y2;

   slope = (y2-y1)/(x2-x1);

   cout<<"Slope is: "<<slope<<endl;

}

Explanation:

First include the library 'iostream' for perform the operation of input/output.

after that, write the main function and declare the variable of points.

use the output command 'cout' for display the message on the screen.

use the input command 'cin' for store the value enter by user into the variable.

after that, use the formula to find the slope:

[tex]slope=\frac{(y_{2}-y_{1})}{(x_{2}-x_{1})}[/tex]

Note: All values declare in the code is float type means decimal value. but you can enter integer value as well.

finally, cout is used to display the output slope on the screen.

write a short C function that takes an integer n and returns the sum of all integers smaller than n.?

Answers

int sumAllNumbersSmallerThanN(int n){

 int sum=0;

 int i;

 for(i=1; i<n; i++){

   sum += i;

 }

 return sum;

}

We simply declared a variable, sum, that will store the result, and set it to zero. Then, we loop all numbers from 1 to n-1, and we sum all these numbers to our sum. When the counter reaches n, the loop stops, and we will have added all numbers from 1 to n-1 in the variable sum.

"int sumofintegers (int n)

{

       int cnt , sum;

       sum = 0;

       for (cnt = 0; cnt<n; cnt++)

       {

               sum = sum + cnt;

       }

return sum;

}

The above function receives the ‘n’ as input and then initialize two variable cnt is used for looping and sum variable to add the numbers which are smaller than the given number.

A for loop is run from 0 to n (not including n since we need to add integers less than n) and then add each value. When the counter reaches n, for loop is exited and the sum is returned to the calling portion.

A frame is

A. the same as the root window
B. a synonym for a component
C. an invisible component that’s used to group other components
D. the padding around the edge of the root window

Answers

Answer:

D. The padding around the edge of the root window.

Explanation

Teacher emailed me the answer

A frame in computing varies in definition based on context, from individual windows in text editors to organizational components in user interfaces or predefined code structures in web development.

Within the context of computing, a frame can refer to various concepts depending on the specific application or environment discussed. For example, in the Emacs text editor, a frame is an individual window that can contain one or multiple editing buffers, potentially split into smaller windows.

On the other hand, in web development and design, frameworks are akin to a collection of predefined code structures and tools that streamline the development process. In general user interfaces, a frame might be an invisible component used to group other components together for organizational purposes. Each of these uses shares a common theme: a frame is a structural element that either contains, organizes, or supports other items within a system or visual context.

1. Think about the various ways in which you have seen hackers portrayed in popular media over the past few years. Are they heroic characters or dangerous criminals? Do the representations conform to any of the realities of the hacker subculture, or do they simply further stereotypes about hackers as a whole?

Answers

They are definitely not heroic characters, so you can rule that out. Definitely dangerous criminals. If you need me to help further I can. Is that a question or an essay?

Final answer:

Portrayals of hackers in media often simplify or sensationalize the hacker subculture, overlooking its complexity and diversity. Understanding the motivations behind hacking activities is crucial, yet resources tend to focus more on technological defenses than on the individuals involved. There is a need to differentiate between hackers and to develop a nuanced view of their activities and ethical considerations.

Explanation:

Popular media often portray hackers as either noble outlaws or dangerous criminals, leaning into stereotypes that may not accurately reflect the realities of the hacker subculture. This binary representation overlooks the complex motivations and ethical frameworks within which many hackers operate. For instance, while some hackers engage in criminal activities for personal gain, others are driven by political ideologies, aiming to expose corruption or promote transparency, akin to what has been observed with groups like Wikileaks.

There is a growing need to differentiate between various types of hackers, rather than lumping them together in a single, often negative, caricature. Understanding who is hacking and why is crucial, yet, as highlighted in discussions, resources are mainly funneled into technological defenses rather than exploring the psychological and sociological aspects of hacking. This approach fails to address the root causes or motivations behind hacking activities, whether they are for malicious purposes, curiosity, or whistleblowing.

Moreover, the representation of hackers in media fails to capture the diversity within the hacker community, which is not monolithic. Attributes commonly ascribed to hackers, such as being male, bright, and socially withdrawn, might resonate with certain stereotypes but do not universally apply. The comparison of some hackers' behavior to that of corporations, as described by Joel Bakan, suggests a need to critically evaluate and understand the ethical dimensions and the potential for 'psychotic' behavior within both entities.
