Study Notes
- A computer program is made up of instructions that are executed one after the other.
- Programs can receive data from various sources like files, keyboards, touchscreens, or networks.
- Programs perform calculations on data, such as adding two values.
- Programs can output data to a file, screen, or network.
- Programs use variables to refer to data.
- A variable's value changes as a program assigns it new values.
- Computational thinking, involves creating a sequence of instructions to solve a problem.
- An algorithm is a sequence of instructions that solves a problem.
- Turtle graphics is a common way to learn about algorithms.
- Turtle graphics involves instructing a robotic turtle to walk a certain path using instructions like "Turn left", "Walk forward 10 steps", or "Pen down".
