A logic truth table shows all possible combinations of inputs and their corresponding outputs, illustrating the logical relationships between them.

(4aii)
(i) AND gate
(ii) OR gate


(4aiii)
| X | Y | Z = X AND Y | Z = X OR Y|
|-----|-----|-------------|-----------|
| 0 | 0 | 0 | 0 |
| 0 | 1 | 0 | 1 |
| 1 | 0 | 0 | 1 |
| 1 | 1 | 1 | 1 |

A comparator as a logic device is used to compare two binary inputs to determine their relationship. It can check whether the inputs are equal, or if one is greater than or less than the other, depending on the complexity of the comparator. Simple comparators might just indicate equality or inequality, while more complex ones can provide specific outputs indicating which input is greater or smaller. Comparators are fundamental in digital circuits for sorting, decision-making, and numerical operations.

(TABULAR FORM)
(PICK ANY TWO)

-COMPUTER-
(i) A computer is a physical device that can execute instructions and perform various tasks
(ii) computer consists of hardware components such as processors, memory, and storage devices
(iii) A computer can execute a wide range of programs and applications
(iv) A computer can directly execute machine-level instructions

-INTERPRETER-
(i) interpreter is a software program that translates and executes high-level programming language instructions.
(ii) interpreter is a software component that runs on a computer.
(iii) interpreter is specifically designed to execute programs written in a particular programming language.
(iv) An interpreter must translate the high-level programming language instructions into machine-level instructions before they can be executed.

(5bi)
(PICK ANY ONE)
(i) Easier to read and understand, making the code more maintainable and less error-prone.
(ii) Abstraction from low-level hardware details, allowing the programmer to focus on the problem-solving logic.
(iii) Portability, as high-level language code can be executed on different computer architectures with the help of compilers or interpreters.

(5bii)
(PICK ANY ONE)
(i) Closer to the hardware, allowing for more control and optimization of system resources.
(ii) Faster execution time, as low-level instructions are directly executed by the computer's processor.
(iii) Better understanding of the underlying computer architecture and how it operates.

(5c)
(PICK ANY TWO)
(i) Efficiency: The program should be designed to use system resources (CPU, memory, storage) effectively and minimize computational overhead.
(ii) Reliability: The program should be able to handle unexpected inputs or errors gracefully, without crashing or producing incorrect results.
(iii) Maintainability: The program's code should be organized, well-documented, and easy to understand and modify by other programmers.
(iv) Modularity: The program should be divided into smaller, reusable components or modules that can be easily tested and integrated.
