Algorithm
set of well-defined logical steps that must be taken to perform a task
Flash Memory
stores data in a special type of memory
Secondary Storage
can hold data for long periods of time even when there is no power
String
sequence of characters that is used as data (Little chunks of text)
Flow Chart
diagram that graphically displays step by step procedure in a program
Source Code
statements written by a programmer
Escape Character
a special character that is preceded with a backslash, appearing inside a string literal.
Program
is a set of instructions that a computer follows to perform a task
Programmer/Software Developer
a person with the training and skills necessary to design, create and test computer programs.
Psuedocode
fake code
ENIAC
first electronic general purpose computer
Assignment statement
used to create a variable and make it referece data
Syntax Error
prevents code from being translated
Data Types
categorized value in memory - e.g. int for integer, float for real numbers, str used for storing strings in memory.
Comments
notes of explanation within a program
Key Words
predefined words used to write a program in high-level language
CPU
is the most important component in a computer
Numeric Literal
number written in a program - No decimal point considered int, otherwise, considered float
Output Device
any data the computer produces for people or other devices
print Function
displays output on the screen
Remainder Operator (%)
performs division and returns the remainder.
Operators
perform operations on data
Statement
individual instruction used in high level language
Assembly Language
uses short words (mnemonics) for instructions instead of binary numbers
High-Level Language
allows simple creation of powerful and complex programs
Assembler
translates assembly language to machine language for execution by CPU
Two types of division
/ operator performs floating point division // operator performs integer division
Operands
values surrounding the operator
Low-Level Language
close in nature to machine language
Variable
name that represents a value stored in the computer memory
Nested Function Call
general format-> function1(function2(argument)) also known as function within a function.
causes output to advance to the next line
Math Operator
tool for performing calculation
Interpreter
translates and executes instructions in High-Level language program
Syntax
set of rules to be followed when writing a program
Exponent Operator (**)
raises a number to a power
Hardware
contains many electronic components
RAM
quickly access data that is stored at any random location
Input Device
is any data the computer collects
Function
piece of prewritten code that perfoms an operation
Garbage Collection
removal of values that are no longer refernced by variables. - Carried out by Python interpreter.
Program Development Cycle
The process that a programmer repeats until not errors are found in a program. Steps are: 1. Design the Program. 2. Write the code. 3. Correct Syntax Errors. 4. Test the executable code. 5. Debug the code.
Math Expressions
performs calculation and gives a value
\"
causes a double quote mark to be printed
Software
is essential to a computer because it controls everything the computer does
Exponentiation
**
String Literal
string that appears in actual code of a program
Argument
data given to a function
Assignment operator
the equal sign
\t
causes output to skip over to the next horizontal tab
