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. -

Lisp: Program Is Data
LISP: PROGRAM IS DATA A HISTORICAL PERSPECTIVE ON MACLISP Jon L White Laboratory for Computer Science, M.I.T.* ABSTRACT For over 10 years, MACLISP has supported a variety of projects at M.I.T.'s Artificial Intelligence Laboratory, and the Laboratory for Computer Science (formerly Project MAC). During this time, there has been a continuing development of the MACLISP system, spurred in great measure by the needs of MACSYMAdevelopment. Herein are reported, in amosiac, historical style, the major features of the system. For each feature discussed, an attempt will be made to mention the year of initial development, andthe names of persons or projectsprimarily responsible for requiring, needing, or suggestingsuch features. INTRODUCTION In 1964,Greenblatt and others participated in thecheck-out phase of DigitalEquipment Corporation's new computer, the PDP-6. This machine had a number of innovative features that were thought to be ideal for the development of a list processing system, and thus it was very appropriate that thefirst working program actually run on thePDP-6 was anancestor of thecurrent MACLISP. This earlyLISP was patterned after the existing PDP-1 LISP (see reference l), and was produced by using the text editor and a mini-assembler on the PDP-1. That first PDP-6 finally found its way into M.I.T.'s ProjectMAC for use by theArtificial lntelligence group (the A.1. grouplater became the M.I.T. Artificial Intelligence Laboratory, and Project MAC became the Laboratory for Computer Science). By 1968, the PDP-6 wasrunning the Incompatible Time-sharing system, and was soon supplanted by the PDP-IO.Today, the KL-I 0, anadvanced version of thePDP-10, supports a variety of time sharing systems, most of which are capable of running a MACLISP. -
