Answer: integer overflow
Explanation:
The type of attack has occurred in this scenario is a integer overflow. An integer overflow occurs when there's an attempt by an arithmetic operation to create a numeric value which is outside the range which the given numbers are able to represent.
In this, the integer overflow occurs when the result of the integer operation cannot be able to fit in the allocated memory space which then brings about an unexpected result.
Answer:
A. 243
B. True
C. 0
Explanation:
Macro instruction is a line of coding used in computer programming. The line coding results in one or more coding in computer program and sets variable for using other statements. Macros allows to reuse code. Macro has two parts beginning and end. After the execution of statement of quiz4 x, 4 the macro x will contain 243. When the macro is invoked the statement will result in an error. When the macro codes are executed the edx will contain 0. Edx serve as a macro assembler.
Answer:
b) Bounded Waiting
Explanation:
int currentThread = 1;
bool thread1Access = true;
bool thread2Access = true;
thread1 { thread2 {
While (true) {
While (true)
{
while(thread2Access == true)
{
while(thread1Access == true)
{
If (currentThread == 2) {
If (currentThread == 1)
{
thread1Access = false; thread2Access = false;
While (currentThread == 2);
While (currentThread == 1);
thread1Access = true; thread2Access = true;
} }
/* start of critical section */ /* start of critical section */
currentThread = 2 currentThread = 1
… ...
/* end of critical section */ /* end of critical section */
thread1Access = false; thread2Access = false;
… ...
} }
} }
} }
It can be seen that in all the instances, both threads are programmed to share same resource at the same time, and hence this is the bounded waiting. For Mutual exclusion, two threads cannot share one resource at one time. They must share simultaneously. Also there should be no deadlock. For Progress each thread should have exclusive access to all the resources. Thus its definitely the not the Progress. And hence its Bounded waiting.
