File Allocation Table - Wikipedia, the Free Encyclopedia Page 1 of 22
File Allocation Table - Wikipedia, the free encyclopedia Page 1 of 22 File Allocation Table From Wikipedia, the free encyclopedia File Allocation Table (FAT) is a file system developed by Microsoft for MS-DOS and is the primary file system for consumer versions of Microsoft Windows up to and including Windows Me. FAT as it applies to flexible/floppy and optical disc cartridges (FAT12 and FAT16 without long filename support) has been standardized as ECMA-107 and ISO/IEC 9293. The file system is partially patented. The FAT file system is relatively uncomplicated, and is supported by virtually all existing operating systems for personal computers. This ubiquity makes it an ideal format for floppy disks and solid-state memory cards, and a convenient way of sharing data between disparate operating systems installed on the same computer (a dual boot environment). The most common implementations have a serious drawback in that when files are deleted and new files written to the media, directory fragments tend to become scattered over the entire disk, making reading and writing a slow process. Defragmentation is one solution to this, but is often a lengthy process in itself and has to be performed regularly to keep the FAT file system clean. Defragmentation should not be performed on solid-state memory cards since they wear down eventually.

File Allocation Table
File Allocation Table File Allocation Table (FAT) is a computer file system architecture and a FAT family of industry-standard file systems utilizing it. The FAT file system is a continuing standard which borrows source code from the original, legacy file Developer(s) Microsoft, NCR, system and proves to be simple and robust.[3] It offers useful performance SCP, IBM, Compaq, even in lightweight implementations, but cannot deliver the same Digital Research, performance, reliability and scalability as some modern file systems. It is, Novell, Caldera however, supported for compatibility reasons by nearly all currently developed Full name File Allocation Table operating systems for personal computers and many mobile devices and Variants 8-bit FAT, FAT12, embedded systems, and thus is a well-suited format for data exchange FAT16, FAT16B, between computers and devices of almost any type and age from 1981 up to FAT32, ExFAT, the present. FATX, FAT+ Originally designed in 1977 for use on floppy disks, FAT was soon adapted and Introduced 1977 with used almost universally on hard disks throughout the DOS and Windows 9x Standalone Disk eras for two decades.[4] As disk drives evolved, the capabilities of the file BASIC-80 system have been extended accordingly, resulting in three major file system Partition MBR/EBR: variants: FAT12, FAT16 and FAT32. The FAT standard has also been expanded identifier FAT12: 0x01 e.a. in other ways while generally preserving backward compatibility with existing (Extended Attribute) software.

Sc. & Engg., Lingaya’s University, Faridabad, India Email: [email protected], [email protected] Abstract — Operating system is a bridge between usable computing system [1]. Moreover, sophisticated system and user. An operating system (OS) is a software operating systems increase the efficiency and consequently program that manages the hardware and software decrease the cost of using a computer [5]. A large number resources of a computer. The OS performs basic tasks, of operating systems of various types are available for both such as controlling and allocating memory, prioritizing research and commercial purposes, and these operating the processing of instructions, controlling input and systems vary greatly in their structures and functionalities output devices, facilitating networking, and managing [1]. files. It is difficult to present a complete as well as deep account of operating systems developed till date. So, this Computers have progressed and developed so have the paper tries to overview only a subset of the available operating systems. Below is a basic list of the different operating systems and its different categories. operating systems and a few examples of operating systems Operating systems are being developed by a large that fall into each of the categories. Many computer number of academic and commercial organizations for operating systems will fall into more than one of the below the last several decades. This paper, therefore, categories.With the integration of computers and concentrates on the different categories of operating telecommunications, the mode of information access systems with special emphasis to those that had deep becomes an important issue. -

A copy of the license is included in the section entitled "GNU Free Documentation License". Introduction 1 Introduction This document describes how to install and use MIT Scheme, the UnCommon Lisp. It gives installation instructions for all of the platforms that we support; complete documen- tation of the command-line options and environment variables that control how Scheme works; and rudimentary descriptions of how to interact with the evaluator, compile and debug programs, and use the editor. The release notes are included as an appendix. This document discusses many operating-system specific features of the MIT Scheme implementation. In order to simplify the discussion, we use abbreviations to refer to some operating systems. When the text uses the term unix, this means any of the unix systems that we support, including GNU/Linux, *BSD, HP-UX, Ultrix, NeXT, and SunOS. The term OS/2 means the IBM OS/2 operating system, version 2.1 or later. We use the term Windows to collectively refer to the Microsoft Windows operating systems: Windows 95, Windows 98, and Windows NT. -
