Wikipedia: Design of the FAT File System
Design of the FAT file system A FAT file system is a specific type of computer file system architecture and FAT a family of industry-standard file systems utilizing it. Developer(s) Microsoft, SCP, IBM, [3] The FAT file system is a legacy file system which is simple and robust. It Compaq, Digital offers good performance even in very light-weight implementations, but Research, Novell, cannot deliver the same performance, reliability and scalability as some Caldera modern file systems. It is, however, supported for compatibility reasons by Full name File Allocation Table: nearly all currently developed operating systems for personal computers and FAT12 (12- many home computers, mobile devices and embedded systems, and thus is a bit version), well suited format for data exchange between computers and devices of almost FAT16 (16- any type and age from 1981 through the present. bit versions), Originally designed in 1977 for use on floppy disks, FAT was soon adapted and FAT32 (32-bit version used almost universally on hard disks throughout the DOS and Windows 9x with 28 bits used), eras for two decades. Today, FAT file systems are still commonly found on exFAT (64- floppy disks, USB sticks, flash and other solid-state memory cards and bit versions) modules, and many portable and embedded devices. DCF implements FAT as Introduced 1977 (Standalone the standard file system for digital cameras since 1998.[4] FAT is also utilized Disk BASIC-80) for the EFI system partition (partition type 0xEF) in the boot stage of EFI- FAT12: August 1980 compliant computers. (SCP QDOS) FAT16: August 1984 For floppy disks, FAT has been standardized as ECMA-107[5] and (IBM PC DOS 3.0) ISO/IEC 9293:1994[6] (superseding ISO 9293:1987[7]). -

After studying this lesson they will be familiar with: 1. What is an operating system? 2. Important functions performed by an operating system. 3. Different types of operating systems. 1. 1 INTRODUCTION Operating system (OS) is a program or set of programs, which acts as an interface between a user of the computer & the computer hardware. The main purpose of an OS is to provide an environment in which we can execute programs. The main goals of the OS are (i) To make the computer system convenient to use, (ii) To make the use of computer hardware in efficient way. Operating System is system software, which may be viewed as collection of software consisting of procedures for operating the computer & providing an environment for execution of programs. It’s an interface between user & computer. So an OS makes everything in the computer to work together smoothly & efficiently.

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.

This field contains a count of hundredths of a second. Because the seconds portion of the DIR_CrtTime field denotes a creation time with a granularity of 2 seconds, this field contains a number of hundredths of a second (0 to 199, inclusively) that denotes a number of seconds from 0 to 1.99, inclusively, that may increment the number of seconds in addition to supplying the number of hundredths of a second. • There is also a typo on page 25 where a field is referred to as DIR_CrtTimeMil (which does not exist), and, as corrected here, should be DIR_CrtTimeHundth 2 SD Documentation • Documentation for the SD controller in the K70 • K70 Sub-Family Reference Manual, Rev. -
