Answer:

Option A is the correct answer choice for the above question.

Explanation:

The computer system needs intercommunication which is done inside the processor to process the task given by the user. There are two types of model is used for intercommunication--

Message passing and
Shared memory

The difference between two is that message passing passes the message on two points at a single unit of time whereas shared memory simultaneous shares the multiple messages. That's why shared memory is faster than message passing.

Hence option A is the correct choice because it also refers to the above concept. While the other is not correct because--
Option B states that message passing is faster than shared memory which is wrong.
Option C states that message passing is used for large data but shared memory is used for large data.
Option D states that shared memory is unavailable in some processor which is wrong.

_____ regulate current/voltage flow, similar function as _____,but are smaller, cheaper, and more reliable.

Tpy6a [65]

Direct Current Power regulates current/voltage flow, similar function as unregulated or regulated, but is smaller, cheaper, and more reliable.

<h3>What is Direct Current Power?</h3>

In contrast to the flow of a river, direct current is a technique in which electricity constantly flows in the same direction. It speaks about the flow of electricity produced by batteries, solar cells, and other sources.
Alternating current (AC), on the other hand, is a technique in which the positive and negative sides are consistently swapped at regular intervals, changing the direction of the electricity flow in accordance.
This is the electricity that comes from a generator or a plug-in.
Alternating current is used to transmit both the electricity generated at power plants and the electricity delivered to houses.

DedPeter [7]

Answer:

d. all of the statements are correct

Explanation:

Frame Relay is a high-performance WAN protocol that operates at the physical and data link layers of the OSI reference model. i.e Layers 1 and 2 They are designed to cope with bursty traffic. Frame relay is also a form of data networking based on packet switching in which the packets are variable in length and experience packet delays.

Based on the above definition the correct statement is option d as all of the statements define in the other option correctly defines the function of frame relay.

Define a python functions that draw a pinwheel using the pinwheel function that has input paramiters that allows you to change t

QveST [7]

Start with your draw_pinwheel() function

During each iteration of the loop decide which color to set the turtle to using the color() function

On even iterations, use color1

On odd iterations, use color2

Use an if/else statement to do the decision making

After deciding the color, surround a call to draw_triangle() with begin_fill() and end_fill() so that drawing the triangle creates a colored triangle.

If you have have forgotten, you can use an if/else to check for even/oddness in python as follows.

my_number = 3

if(my_number % 2 == 0): # the remainder of dividing by 2 is 0

print("The number is "+str(my_number))

print("The number is EVEN")

else: # the remainder must be 1

print("The number is "+str(my_number))

print("The number is ODD")

Good luck <3

int replace_text (Document *doc, const char *target, const char *replacement) The function will replace the text target with the

Paraphin [41]

Answer:

int replace(Document *doc, const char *target, const char *replacement){

int i, j, k;

int beginning;

char temp[MAX_STR_SIZE + 1] ;

char *beginning, *end, *occ, *line;

if(doc == NULL || target == NULL || replacement == NULL)

return FAILURE;

for(i = 0; i < doc->total_paragraphs; i++){

for(j = 0; j < doc->paragraphs[i]->total_lines; j++){

line = doc->paragraphs[i]->lines[j];

beginning = line;

end = beginning + strlen(line);

strcpy(temp, "");

while(beginning < end && (occ = strstr(beginning, target))!= NULL){

len = occ - beginning;

strncat(temp, beginning, len);

strcat(temp, replacement);

beginning = occ + strlen(target);

}

strcat(temp, beginning);

strcpy(doc->paragraphs[i]->lines[j], temp);

}

return SUCCESS;

}

Explanation:

Loop through total paragraphs and total lines.
Store the beginning and ending of paragraph in specific variables.
Copy the remainging chars .
Finally return SUCCESS.
