Study Notes

Programming and Computer Concepts

Application Program Interface (API): A library of predefined classes and interfaces for Java program development.
Assembler: Converts assembly language into machine language, enabling code execution.
Assembly Language: A low-level programming language that simplifies code writing compared to machine language.
Bit: The smallest unit of measurement in computing, represented by a binary digit (0 or 1).
Byte: Comprises 8 bits and can represent one character of alphanumeric data.
Bytecode: Similar to machine code but architecture-neutral, allowing execution across different platforms with a Java Virtual Machine (JVM).

Java Programming

Bytecode Verifier: Validates bytecode to ensure it complies with Java's security settings.
Class Loader: Dynamically loads Java classes into the JVM on demand, abstracting file systems from the runtime environment.
Compiler: Transforms source code from a high-level programming language into a target language, typically object code for execution.
Java Command: Facilitates command-based execution of Java programs.
Java Language Specification: Defines the syntax and semantics of the Java programming language.

Computer Hardware and Connectivity

Cable Modem: Utilizes a cable TV line for internet access, typically offering faster speeds than DSL.
Central Processing Unit (CPU): The microprocessor component responsible for most data processing, consisting of a Control Unit and Arithmetic/Logic Unit.
Digital Subscriber Line (DSL): A technology that transmits digital data for internet access over local telephone network wires.

Software Development Tools

Integrated Development Environment (IDE): Comprehensive software for programming, including a source code editor, build automation tools, and debugger.
Interpreter: Directly converts source code into machine code for execution without generating a separate binary file.
Java Development Toolkit (JDK): Essential software package for developing and running Java applications.

Programming Language Characteristics

High-Level Language: Offers abstraction from computer details, simplifying programming and often automating complex memory management tasks.
Keyword (or reserved word): Special words within a programming language that hold specific meanings and cannot be repurposed.
Library: Contains a collection of predefined classes and interfaces for software development, similar to an API.

Comments and Code Structure

Block Comment: Used for multiline annotations in code, often enclosed in specific delimiters.
Comment: Provides explanatory notes within code to enhance understanding and maintainability.
Line Comment: Enables programmers to include brief explanatory notes using specific symbols.

Display Characteristics

Dot Pitch: Measures the space between pixels on a display, with smaller distances leading to a sharper image quality.

Data Transmission and Encoding

Encoding Scheme: Defines the rules for translating characters, numbers, and symbols into computer-readable data.
