What is a process
100
A common nickname for a thread
What is a lightweight process
100
A synchronization problem where multiple readers and writers are attempting to simultaneously access a shared data file or database.
What is the Readers, Writers problem
100
The process that decides which process should be loaded from the ready list to the CPU next?
What is a short-term scheduler
200
A command to your home directory.
What is cd ~
200
A data structure used to store information about a process?
Process Control Block (PCB)
200
The function for starting a thread in C
What is pthread_create()?
200
A synchronization primitive that can be set to 1 or 0 and will block a process when wait() or P() is called when the value is 0.
What is a mutex?
200
This enables CPU scheduling by allowing a process to be paused and then resume a different process
What is a context switch?
300
This is how you print the path variable for the current user from the terminal in Linux
echo $PATH
300
A procedure to save or restore the state of a process?
What is a context switch
300
A Kernel-level thread
What is a thread that is managed by the operating system so that it can use all available processing cores?
300
A resource allocation problem with 5 processes and 5 shared resources where a solution will ensure concurrency, mutual exclusion, and avoid deadlock?
What is the Dining Philosophers Problem
300
This is a visualization of how the following processes would be executed on the CPU using the Round Robin based short-term scheduler:
400
You type this in the terminal to display process started by the current user
What is ps?
400
A process is waiting on a resource that is not available
What is a Blocked state
400
This part of the Thread Control Block (TCB) are different than the process which started the thread.
What is stack pointer, stack location, or program counter?
400
A hardware operation that atomically copies the value of a variable to a register and then sets the value of the variable to 0. Also the required operation for implementing a mutex.
What is a Test and Set operation
400
Priority-based scheduling algorithms have this potential negative effect.
What is starvation?
500
You type this command to determine how much secondary storage space is available on your system
What is df?
500
A Method of Inter Process Communication between two related processes
What is a pipe?
500
A condition where a thread blocks other threads from entering the critical section of code
What is lockout?
500
A monitor that allows multiple readers into the critical section simultaneously and then allows only one writer into the critical section at a time?
What is the solution to the readers, writers problem
500
This is a visualization of how the following processes would be executed on the CPU using the Priority-based short-term scheduler
What is:
