SLIDE 2 Introduction to Computer Programming Class 1 CSCI-UA 2 Introduction and Overview “Computers and networks finally offer

On Code Literacy

us the ability to write. And we do write with them on our websites, blogs, and social networks. But the underlying capability of the computer era is actually programming—which almost none of us knows how to do. We simply use the programs that have been made for us, and enter our text in the appropriate box on the screen.” —Douglas Rushkoff

SLIDE 14 Introduction to Computer Programming Class 1 CSCI-UA 2 Introduction and Overview Low-level programming languages are

Programming Languages

closer to “machine language”

Low-Level

They are difficult (though not impossible) for humans to read and, as such, are more error-prone

arrangement of words and phrases to create well-formed sentences. Programming language syntax is the arrangement of words and characters to correctly structure programs.
slide-20
SLIDE 20 Introduction to Computer Programming Class 1 CSCI-UA 2 Introduction and Overview

Grammar

Natural language grammar refers to the whole system and structure of a language, such as sentences and paragraphs. Programming languages also implement structure, such as blocks of code and statements within the blocks.
slide-21
SLIDE 21 Introduction to Computer Programming Class 1 CSCI-UA 2 Introduction and Overview Natural languages incorporate different

Parts of Speech

parts of speech, like nouns, verbs, and adjectives. Programming languages also have parts of speech called “data types” that include different kinds numbers and characters.
slide-22
SLIDE 22 Introduction to Computer Programming Class 1 CSCI-UA 2 Introduction and Overview In natural languages, semantics refers

Semantics

to the meaning of a word. “Cat” brings something specific to mind. In programming languages, certain symbols, like + and =, have specific meaning as well as some key words.
