random file organization is a organization were you search a certain object ofr file by the use of any key and in search by randomly

it is a file (C/windows/exe/daw/evdll) is sum random file :)

A swap file is the file that an operating system uses when it is moving data. A computer creates this file when it is moving data from random access memory to virtual memory.

Two file modes are "text" and "binary". Text is used for human readable data, such as a C source file, or a notepad text file. Binary is used for computer readable data, such as an executable object file.

Two other file modes are "sequential" and "random". Sequential is used when the file is accessed serially, from the beginning to the end, and can be used for both text and binary files. Random is used when the file is accessed non-serially, often jumping around from place to place. An example of random is a database file.

Random access simply means the ability to read and write anywhere in the file, as opposed to sequential access where data is simply appended to the end of the file and is accessed by traversing from the start of the file in sequential order. Random access is ideally suited to data arrays where every element in the file is exactly the same length, allowing constant-time traversal from one element to any other, in both directions. If the data is also sorted, random access also allows binary search to improve search efficiency.
