Answer: A) Battery backup
Explanation:
A battery backup are used to provide the source of power backup to various hardware components and desktop computers. In many cases, the devices are plugged into UPS ( uninterruptible power supply) for backup power and it is also depend upon the size of the UPS.
All the battery backups are located inside so that is why, the devices are heavy in weight. Usually, the battery backup front required additional button for performing various functions.
And the battery backup devices are manufacture by using the varying degree of backup abilities.
Answer:
A. Arbitrary code execution
Explanation:
A buffer-overrun, also known as buffer overflow occurs when a programmer makes an error during coding, which could make his system easily susceptible to attacks from a hacker. The root cause of this problem is an overflow of data in a buffer, and programs that are written in C and C+ + are more likely to be affected by this problem. When a buffer-overrun occurs, it would most likely lead to arbitrary code execution.
Arbitrary code execution is an uncontrolled and unrestricted coding by the attacker which alters the original coding. The attacker could input more information into the coding, which alters the original information and which would make the application porous and accessible by just anyone. It is important that programmers run regular tests on their programs, so as to detect any coding errors.
I am not too familiar with the Python language, but the algorithm would be something like this:
1. create a variable for the sums of the number
2. read in how many numbers the user wants to enter (let's call it N)
and then create a for loop:
for N times
read in the next number
increase the sum variable by that number
Hopefully this helps!
