"Cloud Computing Is a Model for Enabling Convenient, On
What is Cloud Computing? "Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction." National Institute of Standards and Technology (NIST) Forum May 2010 http://csrc.nist.gov/groups/SNS/cloud-computing/forum-workshop_may2010.html Cloud Computing concept... it's been around longer than you think "In 1984, John Gage and Bill Joy of Sun Microsystems were credited with saying, "The network is the computer," one of the most memorable slogans of the information age. This concept, based on the tenet of making computing resources available to all users irrespective of location, as long as they are connected to the network, forms the basis of the Internet as we know it, and foretold the advent of cloud computing."

COMPUTER CHAPTER 4- INTRODUCING JAVA Introduction
CLASS-11 SUBJECT – COMPUTER CHAPTER 4- INTRODUCING JAVA Introduction to Java programming JAVA was developed by Sun Microsystems Inc in 1991, later acquired by Oracle Corporation. It was developed by James Gosling and Patrick Naughton. It is a simple programming language. Writing, compiling and debugging a program is easy in java. It helps to create modular programs and reusable code. Bytecode javac compiler of JDK compiles the java source code into bytecode so that it can be executed by JVM. The bytecode is saved in a .class file by compiler. Java Virtual Machine (JVM) This is generally referred as JVM. Before, we discuss about JVM lets see the phases of program execution. Phases are as follows: we write the program, then we compile the program and at last we run the program. 1) Writing of the program is of course done by java programmer. 2) Compilation of program is done by javac compiler, javac is the primary java compiler included in java development kit (JDK). It takes java program as input and generates java bytecode as output. 3) In third phase, JVM executes the bytecode generated by compiler. This is called program run phase. So, now that we understood that the primary function of JVM is to execute the bytecode produced by compiler. Characteristics of Java Simple Java is very easy to learn, and its syntax is simple, clean and easy to understand. Multi-threaded Multithreading capabilities come built right into the Java language. This means it is possible to build highly interactive and responsive apps with a number of concurrent threads of activity. -

SUBJECT: ADVANCE JAVA CSE-306B UNIT : 1 JAVA LANGUAGE BASICS JAVA: Java is a general-purpose, concurrent, object-oriented, class-based, and the runtime environment(JRE) which consists of JVM which is the cornerstone of the Java platform. This blog on What is Java will clear all your doubts about why to learn java, features and how it works. In this What is Java blog, I would be covering following topics: What is Java used for? History of Java What is Java? Features of Java Components in Java What is Java used for? Before I answer the question, what is Java used for, let me brief you about why you should choose Java. Java is highly popular and has dominated this field from early 2000‘s till the present 2018. Java has been used in different domains. Some of them are listed below: Banking: To deal with transaction management. Retail: Billing applications that you see in a store/restaurant are completely written in Java. Information Technology: Java is designed to solve implementation dependencies. Android: Applications are either written in Java or use Java API. Financial services: It is used in server-side applications. Stock market: To write algorithms as to which company they should invest in. Big Data: Hadoop MapReduce framework is written using Java. Scientific and Research Community: To deal with huge amount of data. Wait! Java can do more. 1 Let‘s see how some of the technologies make use of Java as an essential core of their functionalities. -

Programming in Java Unit-I an Overview Of
PROGRAMMING IN JAVA UNIT-I AN OVERVIEW OF JAVA: James Gosling, Patrick Naughton, Chris Worth, ED Frank and Mike Sheridan conceived Java at Sun Microsystems, Inc in 1991. It took 18 months to develop the first Working version. This language was initially called ‘OAK’ but was renamed “JAVA” in 1995. The primary motivation was the need for a platform-independent (i.e. architecture- neutral) language that could be used to create software to be embedded in various consumer electronic devices such as microwave oven and remote controls. As you can probably guess, many different types of CPU’s are used as controllers. The trouble with C and C++ (and most other languages) is that they are designed to be compiled for a specific target. Although it is possible to compile a C++ program for just about any type of CPU, to do so requires a full C++ compiler together for that CPU. The problems are that compilers are expensive and time consuming to create. An easier- more cost efficient solution was needed. In an attempt to find such a solution, Gosling and others began work on a portable, platform-independent language that could be used to produce code that would run on a variety of CPU’s under different environments. This effort ultimately led to the creation of Java. In 1993, the World Wide Web (WWW) appeared on the Internet and transformed the text-based Internet into a graphical rich environment. The project team came up with the idea of developing web applets (tiny programs) using the new language that could run on all types of computers connected to the Internet. -

History of Java the History of Java Is Very Interesting. Java Was Originally Designed for Interactive Television, but It Was
History of Java 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 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 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, Multithreaded, Architecture Neutral, Object-Oriented, Interpreted and Dynamic". Currently, Java is used in internet programming, mobile devices, games, e-business solutions, etc. There are given the significant points that describe the history of Java. 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) Originally designed for small, embedded systems in electronic appliances like set-top boxes. 3) Firstly, it was called "Greentalk" by James Gosling, and file extension was .gt. 4) After that, it was called Oak and was developed as a part of the Green project. Why Java named "Oak"? 5) Why Oak? Oak is a symbol of strength and chosen as a national tree of many countries like U.S.A., France, Germany, Romania, etc. 6) In 1995, Oak was renamed as "Java" because it was already a trademark by Oak Technologies. Why Java Programming named "Java"? 7) Why had they chosen java name for java language? The team gathered to choose a new name.
