Solution:
It is done by Operating system.
An Operating system is system software that manages computer hardware and software resources and provides common services for computer programs.
Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time, mass storage, printing, and other resources.
For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware, although the application code is usually executed directly by the hardware and frequently makes system calls to an OS function or is interrupted by it. Operating systems are found on many devices that contain a computer – from cellular phones and video game consoles to web servers and supercomputers.

Answer: Dereferencing a variable that is not a pointer
Explanation:
The execution time also refered to as the CPU time pertaining to a given task is the time that is used by the system to execute a task.
Some of the reasons for a fatal execution-time error include:
• Dereferencing a pointer that has not been initialized properly
• Dereferencing a null pointer
• Dereferencing a pointer that has not been assigned to point to a specific address.
It should be noted that dereferencing a variable that is not a pointer doesn't cause a fatal execution-time error.
Answer:
In mathematics and digital electronics, a binary number is a number expressed in the base-2 numeral system or binary numeral system, which uses only two symbols: typically "0" (zero) and "1" (one). The base-2 numeral system is a positional notation with a radix of 2. Each digit is referred to as a bit, or binary digit.
Explanation: and the key to reading binary is separating the code into groups of usually 8 digits and knowing that each 1 or 0 represents a 1,2,4,8,16,32,64,128, ect. from the right to the left. the numbers are easy to remember because they start at 1 and then are multiplied by 2 every time.
