Network

 Host - any device which sends or receives traffic.

Client - initiate request. Server - respond.

Server - is simply computer with software installed which responds to specific requests.

IP Address - is the identity of each host. IP Address is 32 bits





Network - is what transports traffic between hosts.


Repeater - regenerates signals


Hub - is simply multi-port Repeater


Bridge - sits between Hub-connected hosts.


Switch - is a combination of Hubs and Bridges.





Router - facilitate communication between networks. 



Gateway - each host's way out of their local Network.

IoC:ApplicationContext, BeanFactory. Bean

 Bean - bean is an instance of a class managed by Spring Boot. In Spring Boot—and the broader Spring Framework—a bean is essentially an object that is managed by the Spring Inversion of Control (IoC) container. Beans are the backbone of a Spring application; they are the components that form the application and are responsible for performing its operations. Key Concepts: Inversion of Control (IoC): Instead of the application code controlling the flow of the program, control is inverted and given to the IoC container. This means the container is responsible for instantiating, configuring, and managing the lifecycle of beans. Dependency Injection (DI): This is a design pattern that allows an object (the client) to receive other objects it depends on (the services) from the IoC container, rather than creating them directly. Defining a Bean: In Spring Boot, you can declare beans in several ways: Using Annotations: @Component : A generic stereotype for any Spring-managed ...

Lesson1: JDK, JVM, JRE

1. Compiler - takes the entire programming code written in high language and translates the whole of it into machine code at once. After this process the an executable file will be ready to run. The translation takes some times to be done, but after that execution is so fast. 2. Interpreter - takes each single instructions of the code translates it and then executes it on its own. The translation step is before the program runs is fast, but execution is slow. JDK = JRE + development tools JRE = JVM + library class JDK -> Java Development Kit. A kit which provides the environment to develop and execute (run) Java program. JRE -> Java Runtime Environment. Provides environment to only run. JVM -> Java Virtual Machine f * Compiled: Fortran, C, C++, Pascal, Haskell, Rust, Go * Interpreted: JavaScript, PHP, Python, Ruby Java both compiled and interpreted language.
