-Design computer hardware and software systems

-Code can be categorized into several types based on its purpose and level of abstraction:

• Machine Code: The lowest level of code, directly executed by the computer's CPU.

• Assembly Language: A low-level code that uses mnemonics to represent machine instructions.

• High-Level Languages: Code that is more abstract and easier for humans to read and write (e.g., Python, Java, C++).

• Code can be categorized into several types based on its purpose and level of abstraction:

  • Machine Code: The lowest level of code, directly executed by the computer's CPU.

  • Assembly Language: A low-level code that uses mnemonics to represent machine instructions.

  • High-Level Languages: Code that is more abstract and easier for humans to read and write (e.g., Python, Java, C++).

• Variables: Named storage locations that hold values. These values can be of different types such as integers, floating-point numbers, characters, and booleans.

• Data Types:

  • Primitive Data Types: Basic data types that are built into the programming language.

  • Integer: Whole numbers (e.g., -3, 0, 5).

  • Floating-Point: Numbers with decimal points (e.g., 3.14, -2.5).

  • Character: Single characters (e.g., 'A', '7').

  • Boolean: Represents true or false values.

  • Composite Data Types: Data types that are composed of primitive data types.

  • Strings: Sequence of characters (e.g., "Hello, World!").

  • Arrays: Collection of elements of the same data type.

  • Structures: Collection of elements of different data types.

• Control Structures:

  • Conditional Statements: Allow different sets of instructions to be executed based on a condition.

  • If-Then-Else: Executes a block of code if a condition is true, otherwise executes another block of code.

  • Looping Statements: Allow a block of code to be executed repeatedly.

  • For Loop: Executes a block of code a specific number of times.

  • While Loop: Executes a block of code as long as a condition is true.

  • Functions/Methods: Reusable blocks of code that perform a specific task.

• Algorithms: Step-by-step procedures or sets of instructions for solving a problem.

• Boolean Logic:

  • AND: Both operands must be true for the result to be true.

  • OR: At least one operand must be true for the result to be true.

  • NOT: Negates the operand (true becomes false, and false becomes true).

• Object-Oriented Programming (OOP):

  • Encapsulation: Bundling data and methods that operate on the data into a single unit (i.e., a class).

  • Inheritance: Allows
