From the Module 1 handout on operating systems, we learned that only machine code runs on the CPU and that this code is not readable by humans.    However, __________________________ is more readable and humans can learn to program in this.    See the image from the handout.

“At 22:00 on every day-of-week from Monday through Friday.” How would this be represented in crontab?

What goes in the blanks?    (note:  it’s the same word in both blanks)   A ___________________ is a program with a unique purpose.  They are utility programs that run silently in the background to monitor and take care of certain subsystems to ensure that the operating system runs properly.  A printer ____________________ monitors and takes care of printing services, for example.

A process can transition from running to suspended ready. How does this transition differ between a single-core system and a multi-core system?

Two different applications on the same device can use the same port number simultaneously without any conflict.
