  • Agile Development Model

    The Agile Development model is a framework used in software engineering to facilitate iterative and incremental development. It emphasizes flexibility, collaboration, and customer feedback, aiming to deliver small, functional pieces of software in short cycles, known as sprints. Key Principles of Agile: Iterative Development: Software is developed in small, manageable chunks. Customer Collaboration: Frequent communication…

  • JIT (just in time ) Compilation (java)

    Just-In-Time (JIT) compilation is a crucial feature in many modern runtime environments, including the Java Virtual Machine (JVM) and .NET CLR, that enhances the performance of programs by converting code into native machine code at runtime. Unlike traditional compilation, which converts all code to machine language ahead of execution, JIT compiles code on the fly,…

  • Compiler (High Level Code translation)

    Compilers are essential tools in programming, designed to transform high-level code written by developers into machine-readable code that a computer’s hardware can execute. They enable languages like C, C++, and Java to be turned into efficient executable programs, making them foundational to software development. Stages of Compilation 1. Lexical Analysis: The compiler starts by breaking…

  • JVM : java virtual machine

    The Java Virtual Machine (JVM) is an essential component of the Java Runtime Environment (JRE), enabling Java applications to run on any device or operating system without modification. By abstracting the underlying hardware, the JVM provides a “write once, run anywhere” capability, which has made Java a versatile and widely-used language in modern software development.…

  • C++ compilers

    C++ compilers are specialized software tools that translate C++ code into machine-readable instructions, making it executable on specific hardware. They are fundamental for software development, transforming high-level C++ language into optimized, efficient binary code. Key Components of a C++ Compiler 1. Preprocessor: The first stage of the compiler, the preprocessor handles directives such as #include…

  • ACID / CAP / SOLID Principle

    ACID properties, SOLID principles, and the CAP Theorem. This analysis will summarize the key points, highlighting the importance of these concepts in software development. ACID Properties ACID (Atomicity, Consistency, Isolation, Durability) ensures reliable database transactions. These properties are crucial for maintaining data integrity and preventing errors. SOLID Principles SOLID (Single Responsibility, Open-Closed, Liskov Substitution, Interface…

  • Factory Design Pattern: Software Design

    The Factory Design Pattern is a creational design pattern widely used to simplify the instantiation of objects in a modular, scalable way. Rather than using constructors directly to create objects, a factory pattern delegates this responsibility to a factory class or method. This approach encapsulates the logic required for object creation, providing a standardized interface…
