Chapter 6: Inside Computers and Mobile Devices

INTRODUCTION:

Inside the case:
The case:- contains and protects electronics of the computer or mobile device from damage.

The motherboard:-main circuit board of the computer
                             - A computer chip contains integrated circuits

PROCESSOR (CPU):

MULTI-CORE PROCESSOR:

FUNCTION OF CONTROL UNIT AND APU:

PROCESSOR CHIP ~ Generates heat

                                    ~ Cause chip to malfunction or fail

Why choose cloud computing?

-> accessibility

-> cost savings

-> space savings

-> scalability

DATA REPRESENTATION:

Two signals:

Analog signals: -continuous in strength and quality

Digital signals: -on or off

                           -mostly computers

MEMORY:

-Electronic components

Function: store instructions and hold temporary instructions and data needed to complete the task

-RAM (Random Access Memory)


3 Basic categories (stores):

Two types of memory:

ADAPTERS:

Adapter card:

Example: Bluetooth, MIDI and Modem

POWER SUPPLY AND BATTERY:

Power supply/ laptop AC adapter	Mobile computers and devices	Batteries
Converts AC power to DC power	Can run using power supply or battery	Rechargeable lithium-ion battery

CONCLUSION:

The inside of the computer contains many components such as the motherboard, the CPU/Processor, RAM, Power supply unit, adapter and many more that are very useful. The same goes to mobile devices. It also contains components such as battery, RAM, Adapter card such as Bluetooth and so much more that makes it a advance technology that is useful for the future.
