Java Definition

Java Definition Java is a high-level programming language developed by Sun Microsystems. It was originally designed for developing programs for set-top boxes and handheld devices, but later became a popular choice for creating web applications. The Java syntax is similar to C++, but is strictly an object-oriented programming language. For example, most Java programs contain classes, which are used to define objects, and methods, […]

JavaScript Definition

JavaScript Definition JavaScript is a programming language commonly used in web development. It was originally developed by Netscape as a means to add dynamic and interactive elements to websites. While JavaScript is influenced by Java, the syntax is more similar to C and is based on ECMAScript, a scripting language developed by Sun Microsystems. JavaScript is a client-side scripting language, which means the source […]

CGI Definition

CGI Definition CGI has two different meanings: 1) Common Gateway Interface, and 2) Computer Generated Imagery. 1) Common Gateway Interface The Common Gateway Interface (CGI) is a set of rules for running scripts and programs on a Web server. It specifies what information is communicated between the Web server and clients’ Web browsers and how the information is transmitted. Most Web […]

Applet Definition

Applet Definition An applet is a small application designed to run within another application. While the term “applet” is sometimes used to describe small programs included with a computer’s operating system, it usually refers to Java applets, or small applications written in the Java programming language. Unlike ordinary applications, Java applets cannot be run directly by the operating system. Instead, […]

JRE Definition

JRE Definition Stands for “Java Runtime Environment” and may also be written “Java RTE.” Java is a programming language, similar to C. However, since it is a newer language, it is not natively supported by all operating systems. Therefore, a Java Runtime Environment may need to be installed on your computer for Java applets and Java applications to run. The […]

JVM Definition

JVM Definition Stands for “Java Virtual Machine.” A JVM is a software-based machine that runs Java programs. It can be installed on several different operating systems, including Windows, OS X, and Linux. JVMs allow Java apps to run on almost any computer. A Java virtual machine processes instructions similar to a physical processor. However, the Java code from a .JAVA file must first be converted into […]

Web Development Definition

Web Development Definition Web development refers to building, creating, and an maintaining websites. It includes aspects such as web design, web publishing, web programming, and database management. While the terms “web developer” and “web designer” are often used synonymously, they do not mean the same thing. Technically, a web designer only designs website interfaces using HTML and CSS. A web developer may […]

Class Definition

Class Definition A class is used in object-oriented programming to describe one or more objects. It serves as a template for creating, or instantiating, specific objects within a program. While each object is created from a single class, one class can be used to instantiate multiple objects. Several programming languages support classes, including Java, C++, Objective C, and PHP 5 and later. […]

Drop Down Menu Definition

Drop Down Menu Definition A drop down menu is horizontal list of options that each contain a vertical menu. When you roll over or click one of the primary options in a drop down menu, a list of choices will “drop down” below the main menu. The most common type of drop down menu is […]

Servlet Definition

Servlet Definition A servlet is a Java program that runs on a Web server. It is similar to an applet, but is processed on the server rather than a client’s machine. Servlets are often run when the user clicks a link, submits a form, or performs another type of action on a website. Both servlets and JSP pages contain Java code that is […]
