Section 1: Engineering Fundamentals and Computer Basics
Question 1
What is the correct definition of a "program" in the context of computing?
A) A physical hardware component that stores data
B) A set of instructions that a computer follows to perform a task
C) An electrical signal processed by the CPU
D) A type of memory used for temporary storage
**Answer: B** A set of instructions that a computer follows to perform a task
**Rationale:** A program is fundamentally a sequence of instructions written in a
programming language that tells the computer what operations to perform. Hardware
components like RAM and the CPU execute these instructions, but the instructions
themselves constitute the program .

**Question 2**
Which of the following best describes the purpose of the CPU in a computer system?
A) To store data permanently for future use
B) To collect input from users and external devices
C) To execute program instructions and process data
, D) To display output results to the user
**Answer: C** To execute program instructions and process data
**Rationale:** The Central Processing Unit (CPU) is the "brain" of the computer. It fetches
instructions from memory, decodes them, and executes the required operations. Secondary
storage devices hold data long-term, while input devices collect data .
---
**Question 3**
What is a "bit" in computer terminology?
A) A group of 8 bytes
B) The smallest unit of data storage, represented as a 0 or 1
C) A type of programming syntax error
D) A unit of processing speed
**Answer: B** The smallest unit of data storage, represented as a 0 or 1
**Rationale:** A bit (binary digit) is the most basic unit of information in computing, having
only two possible values: 0 or 1. A byte consists of 8 bits. The binary language of computers is
composed entirely of sequences of bits .

**Question 4**
Which statement accurately distinguishes between main memory (RAM) and secondary
storage?
