What is different of java & javascript

Image
 What is different of java & javascript  Java and JavaScript are two different programming languages that have some similarities, but they are primarily used for different purposes. Java is a high-level, object-oriented programming language that is widely used for building enterprise applications. It is a compiled language, which means that it is transformed into machine code that can be run on any device that has a Java Virtual Machine (JVM) installed. Java is known for its strong type checking and its "write once, run anywhere" capability, which means that Java programs can run on any device with a JVM. JavaScript, on the other hand, is a scripting language that is primarily used to add interactivity to web pages. It is a client-side language, which means that it is executed by the user's web browser rather than on a server. JavaScript code is usually embedded in HTML pages and is used to add dynamic elements to web pages, such as drop-down menus, pop-up windows, an...

What is java language?

 What is java language ? Java is a high-level programming language that was first released by Sun Microsystems in 1995. It was designed to be easy to use and is known for its "write once, run anywhere" capability, which means that Java programs can run on any device that has a Java Virtual Machine (JVM) installed. Java is a popular choice for building enterprise applications, as it is highly portable and can be used to create a wide range of applications, including web, mobile, and desktop applications. It is also widely used for building Android mobile applications. Java is an object-oriented programming language, which means that it is based on the concept of "objects," which are self-contained units that contain both data and code. Java programs are made up of one or more classes, which are templates for creating objects. Each object is an instance of a class, and it contains its own data and code.

Classification Of Computers

Image
  Classification Of Computers  There are many ways to classify computers, and the specific classification method used can depend on the context in which the computers are being considered. Here are a few common ways to classify computers: Based on size and processing power: Mainframe computers: Large, powerful computers that can process and manage large amounts of data for multiple users simultaneously. Minicomputers : Smaller computers that are used by medium to large organizations, and are capable of handling the needs of a smaller number of users simultaneously. Microcomputers: Personal computers (PCs) that are used by individuals and small businesses, and are typically smaller and less powerful than mainframe and minicomputers. Supercomputers : The most powerful computers available, which are used for tasks that require a high level of processing power, such as simulations, data analysis, and research. Based on purpose: General-purpose computers: Computers that can be pro...

History of Computer

 History of Computer  The history of computers is long and varied, with the first recognizable precursors appearing many centuries ago. The modern computer, as we know it today, has its roots in the work of a number of inventors and scientists who developed the concepts and technologies that form the basis of current computing systems. Here is a brief overview of the history of computers: Pre-modern computers: The earliest known examples of computational devices date back to ancient civilizations in Egypt, Greece, and India. These devices, which were often used for mathematical calculations, included the abacus, the slide rule, and the astrolabe. Early modern computers: In the 19th and early 20th centuries, a number of inventors and scientists developed mechanical and electromechanical devices that could perform calculations more quickly and accurately than humans. These included Charles Babbage's analytical engine, which was designed to perform mathematical calculations using...

What is Data & Information
