Answer:

B. Monitor backlighting

Explanation:

The computer system is a machine that can digitally receive input, process the inputted data and display and save results. The computer system is a physical system driven by a software component.

The computer hardware components are classified as input unit or devices, output unit, memory and storage unit, and processing unit. The screen is an output unit of the computer system, it displays the output or result of the processed data.

The power supply to the screen, in this context, is not faulty due to the other screen used in testing the supply and input connectors. The back light on the screen has failed and that is why the brightness can not be adjusted.

Programs for embedded devices are often written in assembly language. Some embedded processors have limited instructions, like M

oksano4ka [1.4K]

Answer:

#include <iostream>

using namespace std;

int main()

{

char address[2];

int tag, firstBit, secondBit, setNumber;

int cache[4][2]={{1,5}, {2,4}, {3,2}, {6,0}};

cout << "Enter the address as hex(in small letters: "<

cin >> address;

for (int i < 0; i < 8; i++){

if (address[0] == '0'){

tag = 0;

firstBit = 0;

} else if (address[0] == '1'){

tag = 0;

firstBit = 1;

} else if (address[0] == '2'){

tag =1;

firstBit = 0;

} else if (address[0] == '3'){

tag = 1;

firstBit = 1;

} else if (address[0] == '4'){

tag = 2;

firstBit = 0;

} else if (address[0] == '5'){

tag = 2;

firstBit = 1;

} else if (address[0] == '6'){

tag = 3;

firstBit = 0;

} else if (address[0] == '7'){

tag = 3;

firstBit = 1;

} else if (address[0] == '8'){

tag = 4;

firstBit = 0;

} else if (address[0] == '9'){

tag = 4;

firstBit = 1;

} else if (address[0] == 'A'){

tag = 5;

firstBit = 0;

} else if (address[0] == 'B'){

tag = 5;

firstBit = 1;

} else if (address[0] == 'C'){

tag = 6;

firstBit = 0;

} else if (address[0] == 'D'){

tag = 6;

firstBit = 1;

} else if (address[0] == 'E'){

tag = 7;

firstBit = 0;

} else if (address[0] == 'F'){

tag = 7;

firstBit = 1;

} else{

cout<<"The Hex number is not valid"<< endl;

}

}

if(address[1]>='0' && address[1]<'8'){

secondBit = 0;

} else if(address[1]=='8'|| address[1]=='9'||(address[1]>='a' && address[1]<='f')){

secondBit = 1;

} else{

cout<<"The Hex number is not valid"<< endl;

return 0;

}

setNumber = firstBit * 2 + secondBit;

if(cache[setNumber][0]==tag || cache[setNumber][1]==tag){

cout<<"There is a hit";

} else{

cout<< "There is a miss";

}

return 0;

}

Explanation:

The C++ source code prompts the user for an input for the address variable, then the nested if statement is used to assign the value of the firstBit value given the value in the first index in the address character array. Another if statement is used to assign the value for the secondBit and then the setNumber is calculated.

If the setNumber is equal to the tag bit, Then the hit message is printed but a miss message is printed if not.

Write a program that prompts the user to enter a date, using integer values for the month, day, and year, and then prints out th

attashe74 [19]

Answer:

import datetime

user = input("Enter date in yyyy,m,d: ").split(",")

int_date = tuple([int(x) for x in user])

year, month, day =int_date

mydate = datetime.datetime(year, month, day)

print(mydate)

x = mydate.strftime("%B %d, %Y was a %A")

print(x)

Explanation:

The datetime python module is used to create date and time objects which makes it easy working with date-time values. The user input is converted to a tuple of integer items, then they are converted to date time objects and parsed to string with the strftime method.

What is the difference between a Network Diagram and a Wiring Semantic?

stiks02 [169]

Answer:

Network diagram is the type of graphical networking chart that is basically used in the various type of computer telecommunication. The network diagram is useful for the networking designer and also for the network engineer for compiling the network documentation in detail.

Wiring semantic is the type of open source prototype platform which basically composed of the programming language and the IDE ( Integrated development environment). The wiring semantic consumer can affect the triggering the new data or information from the existing concepts.
