A philosophy of making information and knowledge open and accessible to all people. A network of networks built on open, agreed upon protocols.
A widely agreed upon set of rules that standardize communication between machines.
Science that harnesses the power of many individuals to solve hard, complex problems.
Information (numbers, words, measurements, observations, etc) that is in a computer-readable form.
A person or device that makes calculations, stores data, and executes instructions according to a program.
Programs that can be run on a computer
The physical components of a computer
A circuit board with ports and sockets used to connect the main devices of a computer.
A special kind of firmware that runs programs strictly to start up your computer.
The core component of a device that accepts and executes instructions.
A fast type of computer memory which temporarily stores all the information your device needs right away.
A fast access storage device used in computers.
A component designed to speed up the creation of images and output them to a display device, like a monitor.
A component with a built in wired network port that allows the computer to connect to a network.
Command that lets you tell Tracy to move forward. In between the parentheses you need to put a number to tell Tracy how far to move forward.
turns Tracy left at a specified angle
turns Tracy right at a specified angle
determines how quickly Tracy will move through commands
Indentation is the visual structure of how your code is laid out. It uses tabs to organize code into a hierarchy.
Command to change Tracy’s color.
In Python functions, the function body is the indented block of code that comes after the `def my_function():` line. The function body is what will be executed when the function is called.
A message in your code that explains what is going on.
Breaking down (decomposing) your code is splitting it into more functions.
Top down design is a method for breaking our program down into smaller parts.
Pieces of information you can give to functions when you define them. When the function is called the arguments are the data you pass into the function's parameters. Parameter is the variable in the declaration of the function. Argument is the actual value of this variable that gets passed to the function.
An if statement lets you ask a question to the program and only run code if the answer is true.
A control flow tool used as a second condition check after an if statement. It is a contraction of else if.
Control structure that lets us run either one section of code or another depending on a test.
Command that lets you tell Tracy to move backward. In between the parentheses you need to put a number to tell Tracy how far to move backward.
Command that tells tracy to turn right and in between parentheses, how many degrees to turn right.
Command that tells tracy to turn left and in between parentheses, how many degrees to turn left.
A function that prints a prompt and retrieves text from the user.
A function is like a command that you get to invent and name. It allows us to break our program into smaller parts, making the program easier to understand.
Programs that "Read like a story" have good decomposition and make the code easy to follow.
The way your code is written is the style. It covers the aspects of the code that goes beyond whether or not it just works.
