Study Notes
Object Oriented Programming (OOP)
- The main aim of OOP is to organize and structure code in a way that resembles real-world objects and systems.
- The three main items in OOP are classes, objects, and inheritance.
Key Concepts
- Encapsulation in OOP refers to the bundling of data and methods that operate on that data within a single unit, making it harder for other parts of the program to access or modify the data directly.
- Distributed Computing systems have a feature of allowing multiple computers to work together to achieve a common goal.
Distributed Computing
- Microsoft specifically uses the DCOM (Distributed Component Object Model) protocol for Distributed Computing.
- The replacement for DCOM is the .NET Remoting protocol.
Architecture and Technologies
- The technology that grants communication between applications irrespective of storage location is Service-Oriented Architecture (SOA).
- The technology that creates a client/server relationship between objects based on the ORB (Object Request Broker) concept is CORBA (Common Object Request Broker Architecture).
- The technology that abstracts both the web server and the database, serving a web application via a browser is a Three-Tier Architecture.
- The concept that places security requirements on the server side is Three-Tier Architecture.
Programming Languages
- Interpreted languages are generally interpreted without compiling into machine instructions.
- The main advantage of interpreted languages over compiled languages is that they can be executed line by line without the need for a separate compilation step.
- A compiler is a program that translates high-level source code into machine language.
- In an interpreted language, source code is executed line by line during runtime.
- An assembler primarily translates assembly language into machine language.
- An interpreter is a type of program that translates a program statement-by-statement rather than all at once.
Test your knowledge on Object Oriented Programming concepts like classes, objects, encapsulation, and inheritance. Understand the main aim of OOP in binding data and functions, and how messages are used to request services between objects.
