Answer:

a. facilitate improvements but do not necessarily cause them.

Explanation:

Decision Support Systems are interactive Information systems that assist decision makers in coming up with strategies that help the organisation achieve its goals .The model base of the DSS uses mathematical and statistical models to analyse information then it generates reports and suggest possible solutions that can be implemented .The system is capable of giving a specific solution and some even allow the decision makers to give input before suggesting the most applicable solution.The effectiveness of a DSS is equally as important as its efficiency .The DSS unlike the conventional decision-making process should be able to analyse information effectively and come up with solutions in the shortest possible time frame.

Assume that the population of Mexico is 114 million and that the population increases 1.01 percent annually. Assume that the pop

AfilCa [17]

Answer:

#include <bits/stdc++.h>

using namespace std;

// main function

int main()

{

// variables

double mexico = 114;

double usa = 312;

double mexicoRate = .0101;

double usaRate = .0015;

// calculate population after every year until mexico population exceed the usa populationn

while (usa>mexico)

{

// print the population

cout<<"Mexico's population ::"<<mexico<<" million."<<endl;

cout<<"USA's population ::"<<usa<<" million."<<endl;

// update the population

mexico+=mexico*mexicoRate;

usa-=usa*usaRate;

}

return 0;

}

Explanation:

Declare and initialize mexico and usa with their initial population.Also declare and initial their increase and decrease rate.Find the population of both the country each year until mexico population exceeds the usa population.

Output:

Mexico's population ::114 million.

USA's population ::312 million.

Mexico's population ::115.151 million.

USA's population ::311.532 million.

Mexico's population ::270.546million.

USA's population ::274.213 million.

Mexico's population ::273.278million.

USA's population ::273.802 million.

1. How many bits would you need to address a 2M × 32 memory if:

Dominik [7]

Answer:

a) 23 b) 21
a) 43 b) 42
a) 0 b) 0

Explanation:

1) How many bits is needed to address a 2M * 32 memory

2M = 2^1*2^20, while item =32 bit long word

hence ; L = 2^21 ; w = 32

a) when the memory is byte addressable

w = 8; L = ( 2M * 32 ) / 8 = 2M * 4

hence number of bits = log2(2M * 4)= log2 ( 2 * 2^20 * 2^2 ) = 23 bits

b) when the memory is word addressable

W = 32 ; L = ( 2M * 32 )/ 32 = 2M

hence the number of bits = log2 ( 2M ) = Log2 (2 * 2^20 ) = 21 bits

2) How many bits are required to address a 4M × 16 main memory

4M = 4^1*4^20 while item = 16 bit long word

hence L ( length ) = 4^21 ; w = 16

a) when the memory is byte addressable

w = 8 ; L = ( 4M * 16 ) / 8 = 4M * 2

hence number of bits = log 2 ( 4M * 2 ) = log 2 ( 4^1*4^20*2^1 ) ≈ 43 bits

b) when the memory is word addressable

w = 16 ; L = ( 4M * 16 ) / 16 = 4M

hence number of bits = log 2 ( 4M ) = log2 ( 4^1*4^20 ) ≈ 42 bits

3) How many bits are required to address a 1M * 8 main memory

1M = 1^1 * 1^20 , item = 8

L = 1^21 ; w = 8

a) when the memory is byte addressable

w = 8 ; L = ( 1 M * 8 ) / 8 = 1M

hence number of bits = log 2 ( 1M ) = log2 ( 1^1 * 1^20 ) = 0 bit

b) when memory is word addressable

w = 8 ; L = ( 1 M * 8 ) / 8 = 1M

number of bits = 0

. Explain how semaphores are handled in embedded systems design

Readme [11.4K]

Answer:

Semaphores carries the signal between the task and interrupts that does not carry any type of additional data in the embedded system. A semaphore is used as synchronization object and helps in maintain the value between zero and the specific higher value.

It basically reduced the value each time and complete the semaphore object in the embedded system. Binary semaphores is the main type of semaphore that invoke activation of the task.
