1. Floating-point representation: Calculations for normalizing numbers, limitations in representing specific values like +65.20, and addressing precision issues.

2. Protocols in TCP/IP suite: Matching protocols like HTTP, SMTP, IMAP, and BitTorrent with their uses and explaining the role of the Link layer in handling physical connections and framing.

3. Data types: Definitions and applications of enumerated types (fixed set of values) and pointer types (memory address referencing).

4. File organization: Comparison of sequential and random file methods, their access processes, and applications for serial and sequential data structures.

5. Computer architectures: Features and characteristics of SISD (Single Instruction Single Data) and MIMD (Multiple Instruction Multiple Data) systems.

6. Logic circuits: Truth tables for multi-input circuits, Boolean expression simplification using algebra, and reduced expressions.

7. Process states: Key states like running, ready, and blocked; examples of state transitions, such as interrupts or preemptive scheduling.

8. File handling in pseudocode: Usage of user-defined data types, hash-based file location, and pseudocode completion for structured operations like SEEK and CLOSEFILE.

9. Reverse Polish Notation (RPN): Conversion to infix form, stack evaluation for expressions, and operational examples.

10. Stack and queue ADTs: Characteristics, operations like PUSH and POP, pseudocode implementation, and differences in behavior and usage.

11. Declarative programming: Representation of relationships between students and subjects; rules for validating choices and applying logical constraints.

12. Artificial neural networks: Role in machine learning, structure with layers of nodes, and their use in pattern recognition and decision-making systems.
