3. In a multithreaded application, if two threads are attempting to update a
shared counter variable without proper synchronization, what issue might
arise?
The application will run smoothly without any issues.
The counter will automatically synchronize between threads.
A data race may occur, leading to incorrect counter values.
The application will crash due to memory access violations.
4. What Is an acronym?
Suffix
, A word (or abbreviation) formed by the first letters or syllables of
other words.
O
Root word
5. Which of the following describes the purpose of the Java Virtual Machine
(JVM)?
Compiles .java files into .class byte-code files
Acts as a standardized environment to execute .class byte code
programs
Acts like a computer, and handles the interactions with the
underlying operating system and hardware
Compiles java byte code into machine code for the underlying
processor to improve efficiency
6. What is another term used to describe a clock cycle in computer
architecture?
Signal
Pulse
Wave
Tick
7. What is the primary purpose of a branch-and-link instruction in computer
architecture?
It transfers control to a subroutine without saving the return address.
It branches to an address while saving the address of the next
instruction in a register.
, It executes a loop by repeating the current instruction.
It loads data from memory into a register.
8. Bytecode is the result generated by the:
Java compiler
None of the above.
Stack
Heap
9. If a semiconductor manufacturing process has a high rate of defects, what
might be the consequences for the production of personal computers?
Increased production costs and lower yield of functional chips.
Higher efficiency and faster production times.
No change in production costs or yield.
Improved quality of the final computer products.
10. What is the primary function of memory in a computer system?
Transmits data over networks.
Processes data and executes instructions.
Manages input and output devices.
Stores programs and data needed by those programs while they
are running.
11. Describe how the use of transistors in an active matrix display affects its
performance compared to passive matrix displays.
Transistors reduce the power consumption of active matrix displays.
, Transistors allow for faster response times and better image quality
in active matrix displays compared to passive matrix displays.
Transistors enable passive matrix displays to have higher resolution.
Transistors make active matrix displays less expensive to produce than
passive matrix displays.
12. What is the difference between a PUBLIC and a PRIVATE method?
A public method can be accessed from anywhere in the program,
while a private method can only be accessed within the class in
which it was created.
A public method does not need to be attached to an object, while a
private method does.
A private method can be accessed from anywhere in the program,
while a public method can only be accessed within the class in which
it was created.
A public method can be published to the web for web access, while a
private method can only be accessed from within its own method.
13. What is the binary definition of a tebibyte (TiB)?
10^12 bytes
1,000 bytes
2^30 bytes
2^40 bytes
14. Describe how high-level programming languages differ from low-level
programming languages.
High-level languages are faster than low-level languages because
they are compiled directly to machine code.
