Document Summary

File system: the logical view that an operating system provides so that users can manage information as a collection of files. Text file: a file in which the bytes of data are organized as characters from the. Binary file: a file that contains data in a specific format, requiring interpretation. Sequential access: information in the file is processed in order, and read and write operations move the current file pointer as far as needed to read or write the data. The most common file access technique, and the simplest to implement. Direct access: files are conceptually divided into numbered logical records and each logical record can be accessed directly by number. A directory of files can be contained within another directory (parent directory - subdirectory). A directory tree is a logical view of a file system; a structure showing the nested directory organization of a file system. The root directory is the directory at the highest level.
