Q8. A distributed operating system typically consists of:

ALoosely coupled O.S. software on loosely coupled hardware BLoosely coupled O.S. software on tightly coupled hardware CTightly coupled O.S. software on loosely coupled hardware DTightly coupled O.S. software on tightly coupled hardware

Q9. What is the function of the following UNIX command?
wc -l a > b &

AIt runs the word-count program to count the number of lines in its input, file a, writing the result to file b, as a foreground process. BIt runs the word-count program to count the number of lines in its input, file a, writing the result to file b, but does it as a background process. CIt counts the errors during the execution of a process, a, and puts the result in process b. DIt copies a number of lines of a program from file a and stores them in file b.
