CODING Gail Dickinson Madison Ridgeland Academy Mississippi College STEM Institute

WHAT IS CODING? Short Answer Code tells the computer what to do There are many different coding languages that are used for different purposes –For example: computer software, apps, websites

WHAT IS CODING? Long Answer A computer can only understand 2 distinct types of data: on and off is a collection of on/off switches (transistors) only turns on some transistors and turns off some transistors *Binary code is the representation of these combinations*

BINARY CODE is represented in 1s and 0s, where each digit represents one transistor is grouped into bytes, groups of 8 digits representing 8 transistors for example, computers contain millions /billions of transistors, which means an unimaginably large number of combinations.

PROGRAMMING LANGUAGES Thousands of different programming languages make it possible for us to create computer software, apps and websites. Instead of writing binary code, they let us write code that is (relatively) easy for us to write, read and understand. Each language comes with a special program that takes care of translating what we write into binary code.

EXAMPLES OF PROGRAMMING LANGUAGES Java - cross-platform desktop applications Objective C – creating apps for iPhone Swift – new easier way to code iPhone apps C# - builds Window’s desktop applications C, C+ -Low-level operating system, software, libraries. Making things run fast. Python - mathematic and scientific applications Visual Basic - the method used to create what the user sees—the graphical user interface, or GUI

HOUR OF CODE Launched in 2013 Non-profit dedicated to expanding access to computer science o Encourage increased participation by women and underrepresented students o All students in every school should have the opportunity to learn computer science o Computer science should be part of core curriculum, along with science and math Students can sign up to code during their Hour of Code in December (I do it at a different time because of the heavy Internet traffic)
