3V Power Port This can be used as an output to power other devices or an input to power your micro: bit if you are not using a battery or USB.

Accelerometer Measures the acceleration of your micro: bit by sensing how you are physically moving the device.

Abstraction Filtering out patterns of characteristics to create specific instructions/details in order to problem solve or create models

Algorithms A sequence of logical instructions, used to design computer programmes

Component Part of a whole, in this case part of your micro: bit.

CPU (Central Processing Unit) This is where all of the micro: bit’s programming and information is stored and processed. The Bluetooth allows your micro: bit to communicate wirelessly with some other Bluetooth compatible devices. 

Debug Removing bugs (errors) from code to ensure the programme runs correctly (This can involve logical reasoning) 

Decomposing Fragmenting into smaller parts, in order to help understanding or programming

External Component Can be connected to your micro: bit.

GND (Ground) This can be used to complete a circuit. You can even use your hands to do this whilst also touching one of the other pins.

Input Something you can connect to send information to the micro: bit.

LED (Light- emitting diode) You can programme each LED to show numbers, letters or images on your micro: bit. 

Logical reasoning Applying the rules to solve a problem .

Output Something you can connect to your micro: bit which can be sent information.

Sequencing A set of actions that follow on one to another
