Study Notes

File Concept

A file is a contiguous logical address space, which can be categorized into different types, such as:
- Data files (numeric, character, binary)
- Program files (source file, executable file)
- Other types, defined by the file's creator

File Attributes

File attributes are information about a file, including:
- Name: the only human-readable information
- Identifier: a unique tag (number) that identifies the file within the file system
- Type: necessary for systems that support different types of files
- Location: a pointer to the file's location on the device
- Size: the current file size
- Protection: controls who can perform operations such as reading, writing, and executing
- Time, date, and user identification: data for protection, security, and usage monitoring
- Extended file attributes: additional information, such as file checksum

File System Structure

Information about files is kept in the directory structure, which is maintained on the disk
Directory structure can vary, with many variations possible

File Operations

File operations are performed on files, which are stored in the file system
