Answers to Questions (FAQ)
What is a file? (Definition)
A file is a stock unit of numerical data that can contain various types of information, such as text, images, videos, etc.
All numerical/informatic data is stocked with a suite of 0 and 1. A file is container of binary data.
How to create a file from data?
From a sequence of raw data, it is possible to recreate a file.
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 storage is in binary format, but the data is represented differently to the display on a screen to make it a little more readable by a human.
Example: A file containing a byte 01000001 will be represented differently depending on its purpose (or extension)
Text files are usually ASCII encoded, and binary data corresponding to letters, numbers, or printable characters are displayed with the corresponding symbol on the screen.
Example: 01000001 will be represented by the letter A (ASCII code)
Non-text files (executable, compressed, etc.) are stored in binary and can not be read with numbers or letters, often the hexadecimal format is used to represent the binary content faster. The hexadecimal format allows to display with 2 characters one byte (thus 8 bits), which represents a significant visual gain of space.
Example: 01000001 will be represented by the hexadecimal code 0x41
