tolerance‚ and automatic recovery must be integral to the system. Second‚ files are huge by traditional standards. Multi-GB files are common. As a result‚ design assumptions and parameters such as I/O operation and blocksizes have to be revisited. Third‚ most files are mutated by appending new data rather than overwriting existing data. Random writes within a file are practically non-existent.Given this access pattern on huge files‚ appending becomes the focus of performance optimization and atomicity

UNIX offers a file protection system that is straightforward and simple to use. However‚ many people are not aware of the value of this powerful mechanism. A secure environment is achieved not only by the operating system‚ but also through vigilant user and administrative practices. There are many schemes and mechanisms used in the UNIX operating system‚ as well as some simple tricks that are available to give the kind of file protection administrators want. For the purpose of this paper‚ a company

Types of file sharing Peer-to-peer file sharing Users can use software that connects in to a peer-to-peer network to search for shared files on the computers of other users (i.e. peers) connected to the network. Files of interest can then be downloaded directly from other users on the network. Typically‚ large files are broken down into smaller chunks‚ which may be obtained from multiple peers and then reassembled by the downloader. This is done while the peer is simultaneously uploading the chunks

History of File Structures I. Early Work • Early Work assumed that files were on tape. • Access was sequential – The cost of access grew in direct proportion to the size of the file. II. The emergence of Disks and Indexes • As files grew very large‚ sequential access was not a good solution. • Disks allowed for direct access. – Indexes made it possible to keep a list of keys and pointers in a small file that could be searched very quickly. – With the key and pointer‚ the user had direct
