Module 1 Flashcards
Automation
The process of replacing a manual step with one that happens automatically
Client-Side Scripting Language
A programming language used to write scripts that run in the browser on users computer.
Can be used for form validation or updating webpage content dynamically without reloading page
Primarily used for web programming
Main advantages of Client-Side Scripting
Reduces server load, improves user experience, offloads work to client
Code Editors
Tools that provide features including syntax highlighting, automatic indentation, error-checking and auto- correction
Computer Program
A step by step list of instructions that a computer follows to reach an intended goal
Functions
Reusable blocks of code that perform a specific task.
Helps organize and manage code making it more modular, readable, easier to debug
Allows the reuse of code without rewriting it
Modularity
A property of a function.
Modularity breaks complex problems into smaller, manageable tasks
Code is easier to update and maintain when organized into functions
IDE
Integrated Development environment
Software app that provides comprehensive facilities for software development
Interpreter
The program the reads and executes code
Input
Information provided to program by the end-user
Logic Errors
Mistakes in code that cause it to operate incorrectly but not to crash or produce an error message.
Can have unexpected behavior, subtle and challenging to correct
Proper testing, code reviews, and understanding correct logic is required to correct them
Machine Language
The lowest level computer language.
Communicates directly with computer in binary code (ones & zeros)
Object-Oriented Programming Language
OOP
A programming paradigm based on concepts of “objects” that have attributes (data) and methods (functions) to manipulate them
Advantages include modularity, breaking code down into discrete and independent objects, reuse, scalability (easier to manage existing code)
By organizing software design around objects rather than functions or logic, OOP makes it easier for real life problems and manage complex systems
Output
The end-result of a task performed by a function or computer program
Platform-Specific Programming Language
A programming language designed to work only on particular hardware or software. Optimized the take full advantage of the platforms features
Not portable without significant modification
Leads to better performance, direct access to all features and capabilities of platform (APIs, libraries)
Often come with strong support and resources from vendor
Programming
The process of writing a program to behave in different ways
Programming Code
Set of written instructions, guided by rules, using a computer programming language
Programming languages
All have both syntax and semantics that allow humans to more easily interact with computers
Python
A general purpose programming language
A versatile language used for web development, automation, data analysis and others
Python Interpreter
A program that reads and executes Python code by translating it into computer instructions
Scripts
A set of instructions written in a scripting language that is executed by an interpreter rather than directly compiled into machine code
Typically used to automate tasks, manipulate data, enhance the functionality of existing systems or applications
Common Scripting Languages
Python
JavaScript: primarily used for adding interactivity to web pages
Bash: commonly used for writing shell scripts in Unix-based operating systems
Ruby: known for its simplicity and productivity. Used in web development and automation
Semantics
The intended meaning or effect of statements in both human and computer languages
Concerns the meaning and behavior of code, ensuring it performs the intended tasks
Semantic errors occur when code is syntactically correct but doesn’t do what the programmer intended
Syntax
The rules that define the structure of a valid program
The correct arrangement of symbols, keywords, operators to form statements and expressions
Refers to the rules that govern the structure of code
Syntax errors occur when code doesn’t conform to the languages syntax rules
They are typically caught at compile-time or interpret-time
Variables
A named storage location in memory that holds a value
Fundamental due to the ability to store, modify and retrieve data dynamically throughout execution of a program
Can be stored in different types of data including numbers, strings, and objects
Play a crucial role in making programs flexible and powerful
Provides flexibility to manage dynamic into, facilitates code reusabikity, and enhance maintainability of programs
