THINK: What is a computer?

I will now give you 20 seconds silent thinking time to think about what is a computer? 

What is it's purpose? 

What different forms can they take?

PAIR - What is a computer?

I will now give you 1 minute to discuss what you think a computer is with a partner?

What is it's purpose?

What different forms can they take?

SHARE: Write a definition - What is a computer?

KO:Understand basic computer hardware

Core:

Identify key pieces of input, output and storage devices and know their purpose in a computer

ALL - Know what input / output devices are

MOST - Can describe a range of input / output devices and can explain their purpose

SOME - Can explain how primary / secondary storage is used in a computer

Which of these is a computer?

Computer

Not a computer

QUESTION: What are Input and Output devices?

Cold Call

Definitions

Input

A device that sends data/signals into a computer

Output

A device that receives data/signals from a computer (usually after it has been processed)

Sort the input and output devices listed above out into input and output dvices.

Input Device

Output Device

Input devices are devices that…

Output Devices are devices that…

What about a touch screen? Is it an input, or an output device?

An input device is a device that...

1. Sends data from the computer
2. Sends data to the computer
3. Stores data from the computer
4. Uses volatile data

An output device is a device that...

1. Gets data sent to it from the computer
2. Sends data to the computer
3. Stores data from the computer
4. Uses volatile data

A speaker is an example of a...

1. Input Device
2. Storage Device
3. Output Device
4. Primary Memory

A camera is an example of a...

1. Input Device
2. Storage Device
3. Output Device
4. Primary Memory

Secondary Storage

Watch carefully, as you will be answering a question on the next slide...

What is the difference between Primary storage (RAM) and Secondary Storage (Hard Disk)

Cold Call

What is meant by the term Volatile (memory)?

Cold Call

A hard disc is an example of a...

1. Input Device
2. Storage Device
3. Output Device
4. Primary Memory

What is a disavantage of a USB flash drive

1. Is portable
2. Can store documents
3. Can store large files (over 1 TB depending on stick)
4. Can be easily lost

RAM is an example of a...

1. Input Device
2. Storage Device
3. Output Device
4. Primary Memory

A secondary storage device stores data...

1. While it is in use
2. Permanently stores data - even when switched off
3. Stores data when Computer is on
4. As a backup

Memory (RAM) stores data...

1. While it is in use
2. While it is NOT being used
3. All the time
4. As a backup

Memory (RAM) is volatile. This means that...

1. It is likely to corrupt
2. Data is always stored on the chip
3. Data is lost when there is no current passing through the chip
4. It has a tendency to explode
