Answers to Questions (FAQ)
What is a file? (Definition)
A file is a unit of digital data storage, recorded on a medium (hard drive, SSD, USB flash drive, etc.) and managed by a file system.
A file contains a finite sequence of bits, that is, values ​​of 0 and 1. A file (text, image, sound, video, program) is therefore a container of binary data.
How to create a file from data?
From a sequence of bits, it is possible to create a file by writing this data onto a storage medium.
Example: The sequence of binary characters 01000001 (8 bits size or 1 byte) can be written to a file.
The process of creating a file is managed by the operating system, the action of generating a file generally takes 3 steps: opening the file, writing the file, closing the file.
How to read a data file?
Data is stored in binary, but it is interpreted and displayed using an encoding or format to be understandable to the user.
If a file contains the byte 01000001, its decimal value is 65. In ASCII encoding, the number 65 corresponds to the letter A. The display therefore depends on a lookup table between numbers and characters.
Text files use an encoding (ASCII, UTF-8, etc.) to associate numbers with characters visible on the screen.
Non-text files (executables, compressed files, images, etc.) also contain bits, but their interpretation requires specialized software. When displayed in a text editor, they often appear unreadable because the bytes do not correspond to printable characters. The hexadecimal format is a practical representation of binary. A hexadecimal digit corresponds to 4 bits, and thus a byte (8 bits) is represented by two hexadecimal digits.
Example: 01000001 will be represented by the hexadecimal code 0x41
