By the time you’ve explored variables, loops, functions, and more, you’ll have gained a solid foundation to confidently navigate the fascinating landscape of coding and computation. Let’s jump in and demystify the world of tech one concept at a time! Here are 50 definition of basic computing concepts:
- Computer: An electronic device that performs various tasks using electronic components.
- Example: Personal computers, laptops, smartphones.
- Computer Programming: Writing instructions (code) for a computer to follow.
- Example: Creating a program to calculate the average of numbers.
- Data: Information processed and stored by computers.
- Example: Text in a document, numbers in a spreadsheet.
- Code: Instructions written in a programming language.
- Example: Writing code to print “Hello, World!” on the screen.
- Program: A collection of code that performs specific tasks.
- Example: A program that plays music files.
- Algorithm: Step-by-step instructions to solve a problem.
- Example: A recipe for baking a cake.
- Variable: Named storage holding data in a program’s memory.
- Example: Storing a person’s age as a variable.
- String: A sequence of characters, often used for text.
- Example: “Hello, World!” is a string.
- Integer: A whole number without decimals.
- Example: 42, -17.
- Float: A number with a decimal point.
- Example: 3.14, -0.5.
- Boolean: A data type with values “true” or “false.”
- Example: Checking if it’s raining (true) or not (false).
- Function: Reusable code performing a specific task.
- Example: A function to calculate the square of a number.
- Parameter: Value passed to a function for its task.
- Example: Sending a number to a function to calculate its square.
- Argument: Actual value passed as a parameter to a function.
- Example: Passing 5 as an argument to calculate its square.
- Operator: Symbol performing operations on data.
- Example: + for addition, – for subtraction.
- Conditional Statement: Construct for making decisions.
- Example: If it’s sunny, go to the park; otherwise, stay home.
- Loop: Repeats instructions until a condition is met.
- Example: Printing numbers 1 to 10 using a loop.
- Array: Holds multiple values of the same type.
- Example: An array of temperatures for a week.
- Index: Position number for accessing array elements.
- Example: Accessing the 3rd element of an array.
- String Concatenation: Combining strings.
- Example: Combining “Hello” and “World” to get “Hello, World!”
- Comment: Text ignored by the computer, explaining code.
- Example: // This is a comment explaining the code.
- Debugging: Finding and fixing errors in code.
- Example: Correcting a typo causing a program to crash.
- Syntax: Rules for the correct structure of code.
- Example: Using semicolons to end statements.
- Compilation: Translating code to machine-readable form.
- Example: Compiling a program written in C++.
- IDE (Integrated Development Environment): Software for coding, testing, and debugging.
- Example: Visual Studio Code, PyCharm.
- Runtime: When a program is executing.
- Example: Running a game and controlling a character.
- Input: Data provided to a program.
- Example: Entering your name into a form.
- Output: Result generated by a program.
- Example: Printing the sum of two numbers.
- Library: Pre-written code for common tasks.
- Example: Using a library for creating charts.
- Class: Blueprint for creating objects.
- Example: Class “Car” describing attributes and methods.
- Object: Instance of a class with data and behavior.
- Example: An object of class “Dog” with name and bark method.
- Method: Object-associated function.
- Example: Calling a “getArea()” method on a shape object.
- Inheritance: New class inheriting properties from an existing class.
- Example: Subclass “SportsCar” inheriting from “Car.”
- Polymorphism: Treating objects of different classes uniformly.
- Example: Different animals responding to a “makeSound()” method.
- Attribute: Object property represented as a variable.
- Example: “age” attribute of a person object.
- Encapsulation: Bundling data and methods into an object.
- Example: An “Employee” object with name and salary.
- Modularity: Breaking down a program into smaller modules.
- Example: Separating user interface and data processing.
- Function Call: Invoking a function to execute its code.
- Example: Calling a function to calculate factorial.
- Recursion: Function calling itself to solve a problem.
- Example: A recursive function for calculating Fibonacci numbers.
- Binary: Base-2 number system using 0s and 1s.
- Example: Binary representation of 10 is 1010.
- Byte: Storage unit for data, holding one character.
- Example: Storing the letter ‘A’ in a byte.
- Bit: Smallest unit of data, 0 or 1.
- Example: Representing “on” as 1 and “off” as 0.
- Memory: Storage area for data and instructions.
- Example: RAM (Random Access Memory).
- Operating System: Manages hardware and software.
- Example: Windows, macOS, Linux.
