• Monitor

• To provide power to the computer

• CPU

• To store data permanently

• Power Supply

• To process instructions and manage tasks in a computer

• Hard Drive

• To display images on the monitor

Answer explanation

Which of the following is an example of an input device?

• Monitor

• Keyboard

• Printer

• Speaker

Answer explanation

A keyboard is an input device used to enter data into a computer. In contrast, a monitor, printer, and speaker are output devices that display, produce, or project information.

RAM is considered:

• volatile memory

• permanent storage

• input device

• output device

Answer explanation

RAM is considered volatile memory because it loses its data when the power is turned off, unlike permanent storage which retains data. Therefore, the correct choice is 'volatile memory'.

An SSD is faster than a traditional HDD.

• True

• False

Answer explanation

True. SSDs (Solid State Drives) use flash memory, allowing for faster data access and transfer speeds compared to traditional HDDs (Hard Disk Drives), which rely on spinning disks and mechanical parts.

BIOS stands for:

• Basic Input Output System

• Binary Integrated Operating System

• Basic Internal Output Setup

• Built-In Operating Software

Answer explanation

BIOS stands for Basic Input Output System, which is essential for booting up a computer and managing data flow between the operating system and attached devices. The other options are incorrect definitions.

Match the following types of systems with their correct categories:

• A system based on numbers 0 to 9

• Real-time

• A system based on two possible states, 0 and 1

• Batch

• A system that processes data in groups at scheduled times

• Binary

• A system that responds to inputs immediately

• Decimal

Answer explanation

Batch and Real-time are two types of operating systems. Batch systems process jobs in groups without user interaction, while Real-time systems respond immediately to inputs, making them suitable for time-sensitive applications.

The component responsible for rendering graphics in a computer is (a)   .

• CPU

• RAM

• GPU

• Motherboard

Answer explanation

The GPU (Graphics Processing Unit) is specifically designed to render graphics and handle visual output, making it the correct component for this function. The CPU processes general instructions, while RAM and the motherboard support other functions.

Software updates can improve security and performance.

• True

• False

Answer explanation

True. Software updates often include patches that fix security vulnerabilities and enhancements that improve system performance, making them essential for maintaining a secure and efficient computing environment.

The purpose of a device driver is:

• to allow the operating system to communicate with hardware devices

• to increase the speed of the processor

• to provide internet connectivity

• to store user data

Answer explanation

The correct choice is that a device driver allows the operating system to communicate with hardware devices. It acts as a translator between the OS and the hardware, enabling proper functionality.

IP stands for:

• Internet Protocol

• Internal Program

• Input Process

• Information Provider

Answer explanation
