Internal Computer and Mobile Phone Components

Question 1

What is the primary characteristic that distinguishes an internal component from an external peripheral device in a computer or mobile phone?

Accepted Answer

Internal components are housed within the system unit or chassis, while external peripherals are connected externally.

Question 2

Which internal computer component is often referred to as the 'brain' of the computer and executes instructions and processes data?

Accepted Answer

The Central Processing Unit (CPU).

Question 3

What is the main function of the Motherboard in a computer system?

Accepted Answer

It connects and allows communication between all other hardware components.

Question 4

Which type of memory is described as 'volatile' because it requires electrical power to maintain its data, and all information is lost when the computer is turned off?

Accepted Answer

Random Access Memory (RAM).

Question 5

What is the primary purpose of Read-Only Memory (ROM) in a computer?

Accepted Answer

It contains pre-recorded instructions used to boot up the computer.

Question 6

Which type of storage drive uses flash memory chips, has no moving parts, and is generally faster and more durable than traditional hard drives?

Accepted Answer

Solid State Drive (SSD).

Question 7

What is the function of the Power Supply Unit (PSU) in a computer?

Accepted Answer

It converts alternating current from a wall outlet into regulated direct current power for internal components.

Question 8

In a mobile phone, what is the equivalent component to a computer's Motherboard?

Accepted Answer

The Logic Board.

Question 9

Why do mobile phones use a System on Chip (SoC) instead of separate CPU, graphics card, and network card components?

Accepted Answer

To reduce power consumption, generate less heat, and allow for thinner designs.

Question 10

What is the role of the Power Management Integrated Circuit (PMIC) in a mobile phone?

Accepted Answer

It regulates and distributes electrical power from the battery to the various components.

Question 11

During the boot process of a computer, after the device is powered on, what is the CPU's initial action regarding instructions?

Accepted Answer

The CPU activates and reads the initial startup instructions stored permanently in the ROM.

Question 12

When an application is opened on a computer, where is its data loaded from for quick access by the CPU?

Accepted Answer

From the permanent storage drive into the temporary RAM.

Question 13

What safety precaution is crucial to prevent electrostatic discharge (ESD) from damaging sensitive chips when working inside a computer system unit?

Accepted Answer

Wearing an anti-static wrist strap and connecting its clip to a metal part of the computer chassis.

Question 14

When identifying computer components, where would you typically locate the CPU?

Accepted Answer

Secured directly underneath the CPU cooling fan and heatsink assembly.

Question 15

Which component in a mobile phone is typically the largest, flat, rectangular component occupying most of the space inside?

Accepted Answer

The battery.

Question 16

When drawing a simple RAM module, what feature is typically represented as a series of small, evenly spaced vertical lines along the bottom edge?

Accepted Answer

The gold contact pins.

Question 17

What is the purpose of drawing a small triangle or dot in one of the outer corners when representing a CPU?

Accepted Answer

To represent the alignment key (Pin 1 indicator).

Question 18

According to the summary table, what is the mobile phone equivalent of a computer's Hard Disk Drive (HDD) or Solid State Drive (SSD)?

Accepted Answer

Flash Memory (eMMC / UFS).

Question 19

What is the primary function shared by both a computer's Motherboard and a mobile phone's Logic Board?

Accepted Answer

Connects all components and allows them to communicate.

Question 20

When a user saves a document, photo, or file on a computer, what is the data transfer process that occurs?

Accepted Answer

The CPU transfers the data from the volatile RAM back to the non-volatile storage drive for permanent storage.

Strong work.
