True or false?

1) Some programs running on a CPU are written in programming languages that cannot be translated into the native machine instructions for the CPU.

2) Machine language defines instructions that can be executed by a computer's Central Processing Unit (CPU). Each instruction causes the CPU to perform a very specific task, such as a load, a jump, or an Arithmetic Logic Unit (ALU) operation on a unit of data in a CPU register or memory.

3) The following command will output the paths of all files that contain the string stdio.h within /usr/include or any path that contains /usr/include as long as you have permissions to read the directories' contents and the files' contents.

find . -name 'stdio.h' -exec grep -l -E 'stdio.h' {} \;

4)The following find command will find all files and directories inside /usr/include with names ending in .h as long as you have permissions to read the directories' contents:

find /usr/include -name '*.h' -print

5)Preemptive process scheduling schemes are derministic and therefore unsuitable for use in safety critical systems.

6)A context switch cannot also occur as the result of an interrupt, but all operating systems do require a context switch privileges/permissions between user mode and kernel mode tasks.
