The O(1) scheduler is based on priority classes

Real-time FIFO threads can be preempted by Real-time round robin threads

A thread making a system call in Linux will block the parent process

In the O(1) scheduler, the next task to run is picked from the Active array

Choosing the next task to run in the CFS scheduler has complexity logarithmic in the number of tasks

The typical user behaviour on Android requires to manage processes differently than on Linux

All Java application processes are created from the zygote process

A music streaming service playing music in the background is an example of Activity

Processes in Android usually communicate via pipes

In ext3 journals are discarded if the file system has not been unmounted properly

Once a remote directory has been mounted in the local directory hierarchy, its files can be manipulated using ordinary read/write system calls

Ext2 allows two unrelated processes to share the file position

A file system must implement files as i-nodes in order to be supported by VFS

Permissions of the executable file are checked

Machine registers are set to 0

Some pages are loaded into memory before the process starts running the executable file

The text segment is set to be shared with the parent process

Processes B and D are deadlocked

A has requested resource R

Processes B and C are deadlocked

C has acquired resource R

D has acquired resource S
