  • Introduction to MS-DOS

    Introduction to MS-DOS

    1.Introduction to MS-DOS : MS-DOS (Microsoft Disk Operating System) was the Microsoft-marketed version of the first widely-installed operating system in personal computers. It was essentially the same operating system that (Bill Gates's) young company developed for IBM as Personal Computer - Disk Operating System in 1981. Most users of either DOS system simply referred to their system as Disk Operating System. Like PC-DOS, MS-DOS was (and still is) a non-graphical line-oriented command- driven operating system, with a relatively simple interface but not overly "friendly" user interface. Its prompt to enter a command looks like this: C:\> MS-DOS does not care about anything called an icon, wallpaper or screen saver. Rather than being considered as a Graphical User Interface (GUI) MS-DOS is what is known as a command-line interface. You type commands on what is called the command line. MS-DOS is a single-user, single-tasking computer operating system. In spite of its very small size and relative simplicity, it is one of the most successful operating systems that has been developed to date. In DOS, a file name consists of eight character followed by a 3 character file extension. The size of a file is restricted to a 4 byte file descriptor, which limits a file’s maximum size to approximately 4 billion characters. The first release of DOS could not read or write to disk drives so users could only read and write to a floppy disc. DOS was not a state of the art operating system, even for its time.

    A Study on Various Programming Languages to Keep Pace with Innovation

    S.Sridhar* et al. (IJITR) INTERNATIONAL JOURNAL OF INNOVATIVE TECHNOLOGY AND RESEARCH Volume No.5, Issue No.2, February – March 2017, 5681-5704. A Study On Various Programming Languages To Keep Pace With Innovation S.SRIDHAR Professor & Director RV Centre for Cognitive & Central Computing R.V.College of Engineering, Mysore Road Bangalore-560059 India Abstract: A programming language is a formal computer language designed to communicate instructions to a machine, particularly a computer. Programming languages can be used to create programs to control the behaviour of a machine or to express algorithms. The earliest known programmable machine preceded the invention of the digital computer and is the automatic flute player described in the 9th century by the brothers Musa in Baghdad, "during the Islamic Golden Age". From the early 1800s, "programs" were used to direct the behavior of machines such as Jacquard looms and player pianos. Thousands of different programming languages have been created, mainly in the computer field, and many more still are being created every year. Many programming languages require computation to be specified in an imperative form (i.e., as a sequence of operations to perform) while other languages use other forms of program specification such as the declarative form (i.e. the desired result is specified, not how to achieve it). The description of a programming language is usually split into the two components of syntax (form) and semantics (meaning). Some languages are defined by a specification document (for example, the C programming language is specified by an ISO Standard) while other languages (such as Perl) have a dominant implementation that is treated as a reference.

  • An Introduction to the EMACS Editor

    An Introduction to the EMACS Editor

    MASSACHUSETTS INSTITUTE OF TECHNOLOGY ARTIFICIAL INTELLIGENCE LABORATORY AI Memo No. 447 November 1977 An Introduction to the EMACS Editor by Eugene Ciccarelli » Abstract: The intent of this memo is to describe EMACS in enough detail to allow a user to edit comfortably in most circumstances, knowing how to get more information if needed. Basic commands described cover buffer editing, file handling, and getting help. Two sections cover commands especially useful for editing LISP code, and text (word- and paragraph-commands). A brief "cultural interest" section describes the environment that supports EMACS commands. EMACS Introduction 2 9 December 1977 Preface This memo is aimed at users unfamiliar not only with the EMACS editor, but also with the ITS operating system. However, those who have used ITS before should be able to skip the few ITS-related parts without trouble. Newcomers to EMACS should at least read sections 1 through 5 to start with. Those with a basic knowledge of EMACS can use this memo too, skipping sections (primarily those toward the beginning) that they seem to know already. A rule of thumb for skipping sections is: skim the indented examples and make sure you recognize everything there. Note that the last section, "Pointers to Elsewhere", tells where some further information can be found. There can be a great deal of ambiguity regarding special characters, particularly control-characters, when referring to them in print. The following list gives examples of this memo's conventions for control-characters as typed on conventional terminals: IB is control-A. Ii is control-®. (Which you can also type, on most terminals, by typing control-space.) i is altmode (labeled "escape" on some terminals, but be careful: terminals with meta keys, e.g.
