Session 6 - Internal Components, Analogue and Digital Data

What did we learn last week?

Learnt about some of the roles of the internal components of a computer:

The motherboard

CPU

Heat sink

Power Supply

RAM

ROM

Cache Memory

Tested your knowledge on topics from Learning Aim A

Which memory is faster, cache or RAM?

1. RAM
2. Cache memory

What is the main function of a motherboard?

1. Manages power supply
2. Connects all computer components
3. Provides internet connectivity
4. Stores application software

What does BIOS stand for?

1. Binary Integrated Operating System
2. Basic Internal Operating System
3. Bit Input/Output Service
4. Basic Input/Output System

What is the main function of a CPU?

1. Process instructions and data
2. Store data permanently
3. Provide power to components
4. Cool the computer

What does a heat sink do?

1. Dissipate heat from components
2. Store data
3. Increase power supply
4. Boost CPU speed

What is the role of a power supply?

1. Store data permanently
2. Increase CPU speed
3. Convert AC to DC power
4. Cool the CPU

Aims today

Be able to:

Explain about the different types of storage

The significance of Clock speed

The role of buses

Consider the different needs when designing a mobile device

Benefits of a SoC

Explain the differences between analogue and digital data 

Explain the advantages and disadvantages of using analogue and digital data

Recognise the importance of converting analogue data to digital data in modern technology

4 Minute quick research

Think Pair Share - 1 minute discussion on what you think are the differences between an HDD and an SSD

Carry out some research in your pair - 3 minutes - Find at least two differences/advantages of an SSD over an HDD

Now to share your key differences

Explain the difference between a Hard Disk Drive (HDD) and a Solid-State Drive (SSD)

A Hard Disk Drive (HDD) is a traditional storage device that uses spinning magnetic disks (platters) to store data. A read/write head moves across the platters to access or write data.

A Solid-State Drive (SSD), on the other hand, has no moving parts and uses flash memory to store data electronically. This makes it much faster than an HDD.

What is a CPU clock speed, and how is it measured?

1 Hertz = 1 cycle per second

1 MHz = 1 million cycles per second

1 GHz = 1 billion cycles per second

03:30

How does an increase in CPU clock speed affect a computer's performance?

Examines out of order instructions. 

Branch Prediction which is a feature that anticipates what might be next.

04:02

What factors, other than clock speed, influence a CPU's overall performance
