Inheritance (object-oriented programming)

In object-oriented programming, inheritance is the mechanism of basing an object or class upon another object (prototype-based inheritance) or class (class-based inheritance), retaining similar implementation. Also defined as deriving new classes (sub classes) from existing ones (super class or base class) and forming them into a hierarchy of classes. In most class-based object-oriented languages, an object created through inheritance (a "child object") acquires all the properties and behaviors of the parent object (except: constructors, destructor, overloaded operators and friend functions of the base class).

Java (programming language)

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

C Sharp (programming language)

C#Visual C#C# programming language
C# (pronounced C sharp) is a general-purpose, multi-paradigm programming language encompassing strong typing, imperative, declarative, functional, generic, object-oriented (class-based), and component-oriented programming disciplines. It was developed around 2000 by Microsoft within its .NET initiative and later approved as a standard by Ecma (ECMA-334) and ISO (ISO/IEC 23270:2018). C# is one of the programming languages designed for the Common Language Infrastructure.

A database is an organized collection of data, generally stored and accessed electronically from a computer system. Where databases are more complex they are often developed using formal design and modeling techniques.

Internet Direct

Internet Direct, also known as "Indy", is a free software / open source socket library written in Object Pascal, an object-oriented version of Pascal. It includes clients, servers, TCP, UDP, and raw sockets, as well as over 100 higher level protocols implementations such as SMTP, POP3, NNTP, and HTTP. Indy includes support for OpenSSL and Zlib in the protocol implementations. Indy 10 was ported to Free Pascal, and runs on Windows, FreeBSD, Linux, and Darwin.

C (programming language)

CC programming languageC language
C (, as in the general-purpose, imperative computer programming language, supporting structured programming, lexical variable scope and recursion, while a static type system prevents many unintended operations. By design, C provides constructs that map efficiently to typical machine instructions, and therefore it has found lasting use in applications that had formerly been coded in assembly language, including operating systems, as well as various application software for computers ranging from supercomputers to embedded systems.

Microsoft Visual C++

Visual C++MSVCMicrosoft
Microsoft Visual C++ (often abbreviated to MSVC) is an integrated development environment (IDE) product from Microsoft for the C, C++, and C++/CLI programming languages. MSVC is proprietary software; it was originally a standalone product but later became a part of Visual Studio and made available in both trialware and freeware forms. It features tools for developing and debugging C++ code, especially code written for the Windows API, DirectX and .NET.

Macro (computer science)

macromacrosmacro language
A macro (short for "macroinstruction", from Greek μακρός 'long') in computer science is a rule or pattern that specifies how a certain input sequence (often a sequence of characters) should be mapped to a replacement output sequence (also often a sequence of characters) according to a defined procedure. The mapping process that instantiates (transforms) a macro use into a specific sequence is known as macro expansion. A facility for writing macros may be provided as part of a software application or as a part of a programming language. In the former case, macros are used to make tasks using the application less repetitive.


Advanced Technology GroupAgreement with MicrosoftDSG
Novell, Inc. was a software and services company headquartered in Provo, Utah. Its most significant product was the multi-platform network operating system known as Novell NetWare, which became the dominant form of personal computer networking during the second half of the 1980s and first half of the 1990s. Novell technology contributed to the emergence of local area networks, which displaced the dominant mainframe computing model and changed computing worldwide. Novell became instrumental in making Utah Valley a focus for technology and software development.


AppWare was a rapid application development system for Microsoft Windows and the classic Mac OS based on a simple graphical programming language. Applications were constructed by connecting together icons representing objects in the program and their commands. The resulting logic could be compiled on either platform and typically only required minor changes to the GUI layout to complete the port.

Thread (computing)

In computer science, a thread of execution is the smallest sequence of programmed instructions that can be managed independently by a scheduler, which is typically a part of the operating system. The implementation of threads and processes differs between operating systems, but in most cases a thread is a component of a process. Multiple threads can exist within one process, executing concurrently and sharing resources such as memory, while different processes do not share these resources. In particular, the threads of a process share its executable code and the values of its dynamically allocated variables and non-thread-local global variables at any given time.
