CS 170 Exam One Terms and Concepts

hardware components: main memory, secondary memory, central processing unit (CPU)
main memory: random-access memory (RAM), address
kinds of values stored in memory: integers, real numbers (floats), characters (using ASCII/Unicode), strings, program instructions
secondary memory: hard disk, floppy disk, CD, flash drive
programming languages: machine language, assembly language, high-level languages, syntax vs. semantics

Python: variables, program statements, assignment statements (how they are different from algebra), print statements, input statements, numeric expressions (operators such as +, -, *, /, //, % and **) and precedence, importance of comments

functions: how to define a function, parameter passing, returning a value from a function, how to call a function, local variables in a function

for loops: using for loops to achieve repetition, syntax of for loops, how indenting is important to indicate what happens inside vs. outside of loops
range function: how the range function works, what it returns for different inputs, how to use it to create the sequences that you want, how it interacts with for loops
accumulation pattern: using for loops to accumulate value in a variable, sums as well as products, initializing the accumulation variable, using += or *= or just var = var + whatever to increment the accumulation variable
