  How booting process works  Concept of Booting: Booting :         Booting is basically the process of starting the computer. When the CPU is first switched on it has nothing inside the Memory. In order to start the Computer, load the Operating System into the Main Memory and then Computer is ready to take commands from the User. Learn the types of booting. What happens in the Process of Booting?         Booting happens when you start the computer. This happens when we turned ON the power or the computer restarts. The system  BIOS  (Basic Input/Output System) makes the peripheral devices active. Further, it requires that the boot device loads the operating system into the main memory. Boot Devices :         Booting can be done either through hardware (pressing the start button) or by giving software commands. Therefore, a boot device is a device that loads the operating sys...

  How computer identify colours Colour identification by computer  :        All images are comprised of pixels which determine its resolution and color. Image color is defined by the pixel light and the level of brightness in each. Computers use pixel locations to identify color patterns. This allows computers and machine learning algorithms to conduct pattern matching and classify images. What’s in an image?          An image is a square grid of numbers, known as pixels. The more pixels we have in an image, the more details we are able to see.  We have all tried making a small image larger, only to see it become blurry, simply because there aren’t enough pixels to create the detail needed at the larger size.  In short, the image resolution means the level of detail an image holds - the higher the resolution, the higher the level of detail. There are a number of ways of measuring resolution, but it is often ...

            AND GATE To start with you have to understand transistors in a simple way. I will deal with CMOS since 99% of all logic that has ever existed (in number count) exists as CMOS. There are two kinds of transistors used, PMOS and NMOS, here are their symbols:                                      Fig 1 The transistors are electrically controlled current sources/sinks. The PMOS will source current (the dotted line in the diagram shows current flow when on) from a power supply (attached to source) through the drain and into other circuits when the Gate voltage is LOWER than the source. The NMOS will sink current into ground through the drain into the source (which in this case you should think of as a sink). Please note that I've taken some liberties with naming for the sake of clarity. PMOS is usually connected to a positive voltage and NMOS is usually conne...

 History: 1) James Gosling, Mike Sheridan, and Patrick Naughton initiated the Java language project in June 1991. The small team of sun engineers called Green Team. 2) Initially it was designed for small, embedded systems in electronic appliances like set-top boxes. 3) Firstly, it was called "Greentalk" by James Gosling, and the file extension was .gt. 4) After that, it was called Oak and was developed as a part of the Green project. **Why Java was named as "Oak"?** Java History from Oak to Java Why Oak? Oak is a symbol of strength and chosen as a national tree of many countries like the U.S.A., France, Germany, Romania, etc. In 1995, Oak was renamed as "Java" because it was already a trademark by Oak Technologies. **Why Java Programming named "Java"?**   •Why had they chose the name Java for Java language? The team gathered to choose a new name. The suggested words were "dynamic", "revolutionary", "Silk", "jolt...

  Introduction to java : Oracle Java is the #1 programming language and development platform. It reduces costs, shorten development timeframes, drives innovation, and improves application services. With millions of developers running more than 60 billion Java Virtual Machines worldwide, Java continues to be the development platform of choice for enterprises and developers. The history of Java is very interesting. Java was originally designed for interactive television, but it was too advanced technology for the digital cable television industry at the time. The history of Java starts with the Green Team. Java team members (also known as Green Team), initiated this project to develop a language for digital devices such as set-top boxes, televisions, etc. However, it was best suited for internet programming. Later, Java technology was incorporated by Netscape. The principles for creating Java programming were "Simple, Robust, Portable, Platform-independent, Secured, High Performance...
