Answer:
C. Denial of Service
Explanation:
Denial of service error occurs when the legitimate users are unable to access the system. They are then unable to access the information contained in the system. This can also be a cyber attack on the system in which user are stopped from accessing their personal and important information and then ransom is claimed to retrieve the attack. In such case system resources and information are temporarily unavailable to the users which disrupts the services.
Answer:
The C code is below.
Explanation:
#define amplitude 1
02 #define b 1
03 #define c 200
04 class Sinewave
05 {
06 protected:
07
08 double freq;
09 int y;

16 void generateSinewave()
17 {
18 COLORREF yellow = RGB(255,255,0);
19 COLORREF lightblue = RGB(173,216,230);
20
21 // make sure the names match
22 SetConsoleTitle(L"ConGraphics");
23 HWND hWnd = FindWindow(NULL, L"ConGraphics");
24 HDC hDC = GetDC(hWnd);
25
26 //for(int x = 0; x < freq; x++)
27 for(int x = 0;; x++)
28 {
29 // center at y = 200 pixels
30
31 y = amplitude*(int)(sin(x/100.0)*100 + 150);
32 SetPixel(hDC, x, y, lightblue);

38 };
Answer:
c) 2^32 times as many values can be represented.
Explanation:
It's funny, this problem comes from a real-life situation, except it wasn't really foreseen :-) And we will encounter a similar problem in less than 20 years.
The difference in terms of storage capacity from 32-bit integers and 64-bits integers is huge.
A 32-bit integer can store (signed) numbers up to 2,147,483,647. (so over 2 BILLIONS)
A 64-bit integer can store (signed) numbers up to 9,223,372,036,854,775,807 (9 BILLIONS of BILLONS)
Answer:
False.
Explanation:
Hot site :- It is a backup service it is always working it allows a enterprise to continue it's computer and network operations in case of a equipment or computer disaster.
