What is the primary role of computers in engineering?

• Entertainment and gaming

• Assisting in problem-solving and design

• Replacing human engineers completely

• Only for documentation purposes

Answer explanation

Computers help engineers by automating calculations, running simulations, designing models, and analyzing data efficiently.

Which of the following is NOT a key element of a computer system?

• Hardware

• Software

• Algorithm

• Peopleware

Answer explanation

A computer system consists of hardware, software, and peopleware, while an algorithm is a process or set of instructions used in programming.

Which component is considered the "brain" of the computer?

• RAM

• Hard drive

• CPU

• GPU

Answer explanation

The Central Processing Unit (CPU) performs calculations, executes instructions, and controls other components.

What is the function of RAM in a computer system?

• Provides long-term data storage

• Temporarily stores data and instructions for active tasks

• Controls external peripherals

• Acts as a backup storage device

Answer explanation

RAM is a volatile memory that provides fast access to data required by the CPU while running programs.

Peopleware refers to:

• The physical components of a computer system

• The intangible programs running on a computer

• The individuals who use and maintain computer systems

• The process of automating computer systems

Answer explanation

Peopleware includes users, programmers, IT staff, and engineers involved in designing and maintaining computer systems.

Which of the following is an example of system software?

• Microsoft Word

• Adobe Photoshop

• Windows Operating System

• AutoCAD

Answer explanation

System software includes operating systems like Windows, macOS, and Linux, which manage hardware resources and provide a platform for applications.

What is the primary difference between hardware and software?

• Hardware is tangible, while software is intangible

• Software is always free, while hardware is expensive

• Hardware is for personal use, while software is only for businesses

• Software is more important than hardware

Answer explanation

Hardware consists of physical components, while software consists of programs and data that control the hardware.

The ____ stage in the IPOS cycle involves entering raw data into the system using devices such as keyboards, mice, and sensors.

Answer explanation

Input refers to the first step in the IPOS cycle, where data is collected or entered into a computer system for further processing. Input devices like keyboards, scanners, and sensors help in feeding data into the system.

The ____ cycle is a model that describes how computers handle and process data, starting from input and ending with output and storage.

Answer explanation

The IPOS cycle is a fundamental concept in computing that explains how data flows through a system. It ensures that computers can efficiently process information, store results, and provide meaningful outputs based on user input.

What type of software is used for designing and modeling in engineering?

• Antivirus software

• CAD software

• Word processing software

• Web browsers

Answer explanation

CAD (Computer-Aided Design) software, such as AutoCAD and SolidWorks, is used for creating detailed engineering designs.
