A CAPTCHA (a backronym for "Completely Automated Public Turing test to tell Computers and Humans Apart") is a type of challenge-response test used in computing to determine whether or not the user is human.

PHP is a server-side scripting language designed primarily for web development but also used as a general-purpose programming language.

Originally created by Rasmus Lerdorf in 1994, the PHP reference implementation is now produced by The PHP Development Team.

PHP originally stood for Personal Home Page, but it now stands for the recursive acronym PHP: Hypertext Preprocessor.

Java is a general-purpose computer programming language that is concurrent, class-based, object-oriented, and specifically designed to have as few implementation dependencies as possible.

It is intended to let application developers "write once, run anywhere" (WORA), meaning that compiled Java code can run on all platforms that support Java without the need for recompilation.

Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of computer architecture.

As of 2016, Java is one of the most popular programming languages in use, particularly for client-server web applications, with a reported 9 million developers.

Java was originally developed by James Gosling at Sun Microsystems (which has since been acquired by Oracle Corporation) and released in 1995 as a core component of Sun Microsystems' Java platform.

The language derives much of its syntax from C and C++, but it has fewer low-level facilities than either of them.

In computing, source code is any collection of computer instructions, possibly with comments, written using a human-readable programming language, usually as ordinary text.

The source code of a program is specially designed to facilitate the work of computer programmers, who specify the actions to be performed by a computer mostly by writing source code.

The source code is often transformed by an assembler or compiler into binary machine code understood by the computer.

The machine code might then be stored for execution at a later time.

Alternatively, source code may be interpreted and thus immediately executed.

NET Framework (pronounced dot net) is a software framework developed by Microsoft that runs primarily on Microsoft Windows It includes a large class library named Framework Class Library (FCL) and provides language interoperability (each language can use code written in other languages) across several programming languages Programs written forNET Framework execute in a software environment (in contrast to a hardware environment) named Common Language Runtime (CLR), an application virtual machine that provides services such as security, memory management, and exception handling (As such, computer code written usingNET Framework is called "managed code") FCL and CLR together constituteNET Framework.
