Computer        Name of Machine

"The computer is an electronic device that access accepts some kind of data, analyzes it, and perform specific operation, to produce some output."

Charles Babbage --- Father of Computer

Alan Turing “Father of the Modern Computer”







Data---- With the help of Input Device
Process-----With the help of Processors (it is also called as CPU)
Information---It is Output Device
Storage--It is HDD hard Disk Drive your data is permanently stored



Block Diagram of Computer 

Dr. John Von Newman
John Von Newman Computer Architecture in 1945

A block diagram is a simplified visual representation of a system, showing its main components (called "blocks") and how they interact using arrows. Each block represents a functional unit, and the arrows show the flow of data or control between them.

Java

What is Java? Java is a simple, object oriented, secure programming language it is developed by James Gosling launched by mid 1992 with the name of Oak. Key Features of Java 1. Simple- Java is design to be easy to learn because it remove C++ pointers and operator overloading 2. Platform Independent- (WORA) Write One Run Anywhere 3. Object Oriented- Everything in Java is an Object (except for basic data types) 4. Robust- Robust means Strong: - Java is design to be handles errors reliably. 1 Garbage Collection 2.Exception Handling 5. Multithreaded- Java is multithread because it has built in capability to perform multiple task simultaneously within a single program. Thread is a smallest unit of execution. In Java every program has at least one thread(the main thread) Multi-thread allows you to spawn “child” threads to handle background work while the main thread stay active. 6.High-Performance- While technically is interpreted, Java uses a JIT (Just-In-Time) Compiler...

  Computer Graphics     What is Computer Graphics? Computer graphics is an art in which images, lines, and charts are created by programming them in a computer. Simply put, "Drawing pictures on a computer screen is called computer graphics." Creating pictures with the help of a computer is called computer graphics. In this, two or three dimensional pictures are created. It uses a lot of software techniques to create, modify, and store pictures. With the help of Computer Graphics, we can display images of any size in the computer screen. Graphics are presented in computers using a lot of algorithms and techniques. Nowadays, computer graphics are used everywhere such as – in user interfaces, in TVs, in motion pictures, and in mobile games, etc. Computer graphics are made up of many pixels. A pixel is the smallest unit of graphics that appear on a computer screen. The term computer graphics was first used by Verne Hudson and William Fetter in 1960. When we draw a pictur...
