Which type of multi-tasking involves allowing several programs to execute concurrently?
Process-based multi-tasking
Which type of multi-tasking enables a single program to execute concurrently?
Thread-based multi-tasking
What are the characteristics of threads in thread-based multi-tasking?

Based on the text, what is the main reason for using multi-threading?
To minimize the idle time of the CPU
In which type of multi-tasking is inter-thread communication inexpensive?
Thread-based multi-tasking
What are the different states a thread exists in the Thread Lifecycle?
Born, active, runnable, dead, blocked
Why is there plenty of idle time for interactive, networked applications?
Local file system resources can be read and written at a much slower rate than can be processed by the CPU
When can a thread be considered dead?
When its run() method completes
What is the entry-point for a thread?
Run
How can a new thread be created in Java?
By implementing the Runnable interface or extending the Thread class
What method is used to wait for a thread to terminate?
Join
How can a thread be suspended for a period of time?
By invoking sleep() method
What determines if a thread is still running?
isAlive() method
What represents the 'Ready-to-run' state of a thread?
Runnable
How does a thread enter the 'Running' state?
The scheduler selects the thread from runnable pool

What distinguishes the interfaces in the Java Collections Framework, as stated in the text?
They represent abstract data types that represent collections
How does the Java Collections Framework benefit program speed and quality, according to the text?
By providing high-performance implementations of data structures and algorithms
What is a key advantage of using the Java Collections Framework, based on the text?
Allows for easy adaptation of collections
Why does the text state that the collection interfaces generally form a hierarchy in object-oriented languages?
To provide a unified architecture for representing and manipulating collections
What is a significant advantage of the Java Collections Framework mentioned in the text?
Frees programmers from writing adapter objects or conversion code
