Answer:
4 bits
Explanation:
With 4 bits you can count to 15, because 2⁴=16. The maximum number you can express is always one less, i.e., 16-1=15.
In general, with n bits you can count to 2ⁿ-1.
The answer is C because they want you to compare it your or others lives.
Answer:
<u>In physics</u>, efficiency is a measure of how much energy is conserved in a process.
<u>In programming</u>, efficiency is directly linked with the speed of runtime execution for software and algorithmic efficiency.
In this comparison, both meanings try to measure the quality of the processes and have formulas to detect this efficiency.
Both meanings have different formulas to define the measures, Big O notation for programming and percentage of energy output divided by energy input for physics. Furthermore, in physics is not possible to get 100% efficiency, but it is possible for programming to have O(1) of efficiency.
Answer: second option: Operating system...
An operating system is the most important software that runs on a computer. It manages the computer's memory and processes, as well as all of its software and hardware. It also allows you to communicate with the computer without knowing how to speak the computer's language.
Hope this helps... Stay safe and have a Merry Christmas!!!!!!! :D
