Answer:
Linux is a type of open-source software. The entire premise of open-source code is to make it as easy for people to develop and share as possible, instead of use as a vehicle to make money. This way, the collective knowledge of the community can make the program as secure and user-friendly as possible.
Explanation:
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.
