Digital systems have components with basic functions that may connect together to form networks which transmit data(ACTDIK014)
Define;
Components:Parts or elements that make up a system or whole object and perform specific functions. For example, the major components of a car include: a chassis (holds everything on it); an engine (to convert energy to make a car move); a transmission (including controlling the speed and output from the engine and to rotate the wheels); a steering system (to control the direction of movement); a brake system (to slow down or stop); a fuel delivery system (to supply fuel to the cylinders); an exhaust system (to get rid of gases) and an electrical system (for operating wipers, air conditioning, etc.).Similarly, the components of a computer system may be a central processing unit (chips that follow instructions to control other components and move data); memory chips and a hard disk (for storing data and instructions); a keyboard, a mouse, a camera and a microphone (to input instructions and data for the central processing unit); a screen, a printer and speakers (to output data); USB and ethernet cards (to communicate with other systems or components).
Data:
In Digital Technologies data refers to, discrete representation of information using number codes. Data may include characters (e.g. alphabetic letters, numbers and symbols), images, sounds and/or instructions that, when represented by number codes, can be manipulated, stored and communicated by digital systems. For example, characters may be represented using ASCII code or images may be represented by a bitmap of numbers representing each ‘dot’ or pixel.

Task:
1. To explain the components of an Ipad and a Computer Tower, explaining the role of each component.
2. How do these components receive and communicate data.

Decision Making and Codes
Task: To design an 'unplugged' light bot inspired course to navigate and to have someone else navigate for you.
Requirements:
- you will place eight (8) values and themes on your course. E.g. courage, family etc. four (4) to six (6) of these are relevant to your novel. Two (2) to four (4) of these are not.
- You need to design a course where you navigate your way through to 'turn on' the values required for your character.
- You need to list the values a partner needs to 'turn on' to complete your character.
- take photos of your design so you can recreate it
