Norton Guides
Norton Guides were a product family sold by Peter Norton Computing. The guides were written in 1985 by Warren Woodford for the x86 Assembly Language, C (programming language), C, BASIC, and Forth (programming language), Forth languages and made available to DOS users via a terminate-and-stay-resident (TSR) program that integrated with programming language editors on IBM PC type computers. Norton Guides appears to be one of the first Online help systems and the first example of a commercial product where programming reference information was integrated into the software development environment. The format was later used by independent users to create simple hypertexts before this concept was more popular. Hypertext capabilities however were limited, links between entries were only possibly by "see also" references at the end of each entry. The concept of providing "information at your fingertips", as he called it, via a TSR program was a signature technology developed by Woodfo ...

Peter Norton Computing
Peter Norton Computing, Inc., was a software company founded by Peter Norton. The first and best known software package it produced was Norton Utilities. Another successful software package was Norton Commander, especially the DOS version. The company in this form lasted from its founding in 1982 until 1990, when it was acquired by Symantec (now Gen Digital). The Symantec merger helped Norton Computing regain the market share it was losing to competitors, especially Central Point Software. Norton Computing's revenues tripled between June 1990 and September 1991, and by November it appeared to have regained the market lead over Central Point. History Peter Norton founded the company in 1982 with $30,000 and an IBM computer. The company was a pioneer in DOS-based utilities software. Its 1982 introduction of the Norton Utilities included Norton's UNERASE tool to retrieve erased data from DOS disks. In 1984, Norton Computing reached $1 million in revenue, and version 3.0 of the Nor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Assembly Language
In computing, assembly language (alternatively assembler language or symbolic machine code), often referred to simply as assembly and commonly abbreviated as ASM or asm, is any low-level programming language with a very strong correspondence between the instructions in the language and the architecture's machine code instructions. Assembly language usually has one statement per machine instruction (1:1), but constants, comments, assembler directives, symbolic labels of, e.g., memory locations, registers, and macros are generally also supported. The first assembly code in which a language is used to represent machine code instructions is found in Kathleen and Andrew Donald Booth's 1947 work, ''Coding for A.R.C.''. Assembly code is converted into executable machine code by a utility program referred to as an '' assembler''. The term "assembler" is generally attributed to Wilkes, Wheeler and Gill in their 1951 book '' The Preparation of Programs for an Electronic Dig ...

C (programming Language)
C (''pronounced'' '' – like the letter c'') is a general-purpose programming language. It was created in the 1970s by Dennis Ritchie and remains very widely used and influential. By design, C's features cleanly reflect the capabilities of the targeted Central processing unit, CPUs. It has found lasting use in operating systems code (especially in Kernel (operating system), kernels), device drivers, and protocol stacks, but its use in application software has been decreasing. C is commonly used on computer architectures that range from the largest supercomputers to the smallest microcontrollers and embedded systems. A successor to the programming language B (programming language), B, C was originally developed at Bell Labs by Ritchie between 1972 and 1973 to construct utilities running on Unix. It was applied to re-implementing the kernel of the Unix operating system. During the 1980s, C gradually gained popularity. It has become one of the most widely used programming langu ...

Forth (programming Language)
Forth is a stack-oriented programming language and interactive integrated development environment designed by Charles H. "Chuck" Moore and first used by other programmers in 1970. Although not an acronym, the language's name in its early years was often spelled in all capital letters as ''FORTH''. The FORTH-79 and FORTH-83 implementations, which were not written by Moore, became '' de facto'' standards, and an official technical standard of the language was published in 1994 as ANS Forth. A wide range of Forth derivatives existed before and after ANS Forth. The free and open-source software Gforth implementation is actively maintained, as are several commercially supported systems. Forth typically combines a compiler with an integrated command shell, where the user interacts via subroutines called ''words''. Words can be defined, tested, redefined, and debugged without recompiling or restarting the whole program. All syntactic elements, including variables, operators, and co ...

Terminate-and-stay-resident
A terminate-and-stay-resident program (commonly TSR) is a computer program running under DOS that uses a system call to return control to DOS as though it has finished, but remains in computer memory so it can be reactivated later. This technique partially overcame DOS's limitation of executing only one program, or task (computing), task, at a time. TSRs are used only in DOS, not in Microsoft Windows, Windows. Some TSRs are utility software that a computer user might call up several times a day, while working in another program, by using a keyboard shortcut, hotkey. Borland Sidekick was an early and popular example of this type. Others serve as device drivers for computer hardware, hardware that the operating system does not directly support. Use Normally DOS can run only one program at a time. When a program finishes, it returns control to DOS using the system call of the DOS API. The memory and system resources used are then marked as unused. This makes it impossible to restar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IBM PC
The IBM Personal Computer (model 5150, commonly known as the IBM PC) is the first microcomputer released in the List of IBM Personal Computer models, IBM PC model line and the basis for the IBM PC compatible ''de facto'' standard. Released on August 12, 1981, it was created by a team of engineers and designers at IBM, International Business Machines (IBM), directed by William C. Lowe and Philip Don Estridge in Boca Raton, Florida. Powered by an x86-architecture Intel 8088 processor, the machine was based on open architecture and third-party peripherals. Over time, expansion cards and software technology increased to support it. The PC had influence of the IBM PC on the personal computer market, a substantial influence on the personal computer market; the specifications of the IBM PC became one of the most popular computer design standards in the world. The only significant competition it faced from a non-compatible platform throughout the 1980s was from Apple Inc., Apple's Maci ...

Online Help
Online help is a form of user assistance that provides topic-oriented, procedural or reference information designed to assist in using a software application, web application or operating system. Online help linked to the application's state (what the user is doing) is called Context-sensitive help. The help information can be created using help authoring tools or component content management systems and can be delivered in a wide variety of proprietary and open-standard formats. Help of this kind has largely replaced printed documentation. Interactive help can also be provided via virtual assistants and Chatbot systems. Microsoft help platforms Microsoft develops platforms for delivering help systems for the Microsoft Windows operating system. Other platforms See also * Balloon help * Darwin Information Typing Architecture *DocBook DocBook is a Semantics (computer science), semantic markup language for technical documentation.

Hypertext
Hypertext is E-text, text displayed on a computer display or other electronic devices with references (hyperlinks) to other text that the reader can immediately access. Hypertext documents are interconnected by hyperlinks, which are typically activated by a mouse (computing), mouse click, keypress set, or screen touch. Apart from text, the term "hypertext" is also sometimes used to describe tables, images, and other presentational content formats with integrated hyperlinks. Hypertext is one of the key underlying concepts of the World Wide Web, where Web pages are often written in the Hypertext Markup Language (HTML). As implemented on the Web, hypertext enables the easy-to-use publication of information over the Internet. Etymology The English prefix "hyper-" comes from the Greek language, Greek prefix "ὑπερ-" and means "over" or "beyond"; it has a common origin with the prefix "super-" which comes from Latin. It signifies the overcoming of the previous linear cons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tempest (codename)
TEMPEST is a codename, not an acronym under the U.S. National Security Agency specification and a NATO certification referring to spying on information systems through leaking emanations, including unintentional radio or electrical signals, sounds, and vibrations. TEMPEST covers both methods to spy upon others and how to shield equipment against such spying. The protection efforts are also known as emission security (EMSEC), which is a subset of communications security (COMSEC). The reception methods fall under the umbrella of radiofrequency MASINT. The NSA methods for spying on computer emissions are classified, but some of the protection standards have been released by either the NSA or the Department of Defense. Protecting equipment from spying is done with distance, shielding, filtering, and masking. The TEMPEST standards mandate elements such as equipment distance from walls, amount of shielding in buildings and equipment, and distance separating wires carrying classified v ...
