    Introduction to PC Operating Systems Operating System Concepts 8th Edition Written by: Abraham Silberschatz, Peter Baer Galvin and Greg Gagne John Wiley & Sons, Inc. ISBN: 978-0-470-12872-5 Chapter 2 Operating-System Structure The design of a new operating system is a major task. It is important that the goals of the system be well defined before the design begins. These goals for the basis for choices among various algorithms and strategies. What can be focused on in designing an operating system • Services that the system provides • The interface that it makes available to users and programmers • Its components and their interconnections Operating-System Services The operating system provides: • An environment for the execution of programs • Certain services to programs and to the users of those programs. Note: (services can differ from one operating system to another) A view of operating system services user and other system programs GUI batch command line user interfaces system calls program I/O file Resource communication accounting execution operations systems allocation error protection detection services and security operating system hardware Operating-System Services Almost all operating systems have a user interface. Types of user interfaces: 1. Command Line Interface (CLI) – method where user enter text commands 2. Batch Interface – commands and directives that controls those commands are within a file and the files are executed 3. Graphical User Interface – works in a windows system using a pointing device to direct I/O, using menus and icons and a keyboard to enter text. Operating-System Services Services Program Execution – the system must be able to load a program into memory and run that program.

    1 Semantic File Retrieval in File Systems using Virtual Directories Prashanth Mohan, Raghuraman, Venkateswaran S and Dr. Arul Siromoney {prashmohan, raaghum2222, wenkat.s}@gmail.com and [email protected] Abstract— Hard Disk capacity is no longer a problem. How- ‘/home/user/docs/univ/project’ directory lists the ever, increasing disk capacity has brought with it a new problem, file. The ‘Database File System’ [2], encounters this prob- the problem of locating files. Retrieving a document from a lem by listing recursively all the files within each directory. myriad of files and directories is no easy task. Industry solutions are being created to address this short coming. Thereby a funneling of the files is done by moving through We propose to create an extendable UNIX based File System sub-directories. which will integrate searching as a basic function of the file The objective of our project (henceforth reffered to as system. The File System will provide Virtual Directories which SemFS) is to give the user the choice between a traditional list the results of a query. The contents of the Virtual Directory heirarchial mode of access and a query based mechanism is formed at runtime. Although, the Virtual Directory is used mainly to facilitate the searching of file, It can also be used by which will be presented using virtual directories [1], [5]. These plugins to interpret other queries. virtual directories do not exist on the disk as separate files but will be created in memory at runtime, as per the directory Index Terms— Semantic File System, Virtual Directory, Meta Data name.
