binääritiedostosta

A binääritiedosto (binary file) is a computer file that stores information in a format that is not easily readable by humans. Unlike text files, which store characters represented by numerical codes (like ASCII or Unicode), binary files store data as sequences of bytes, where each byte can represent a variety of information, including numbers, instructions, or raw data. The interpretation of these bytes depends on the specific file format and the program used to read it.

Common examples of binary files include executable programs (.exe files), image files (.jpg, .png), audio files (.mp3, .wav), and compressed archives (.zip, .rar). When you open a text file in a text editor, you see the characters directly. However, if you try to open a binary file in a text editor, you will typically see a jumble of unreadable symbols, as the editor attempts to interpret the raw bytes as characters.

The use of binary files allows for more efficient storage and processing of data. By avoiding the overhead of character encoding and control characters, binary formats can represent data more compactly and allow for faster reading and writing operations. However, this efficiency comes at the cost of human readability, making it necessary to use specific software designed to understand and process each particular binary file format. Debugging and analyzing binary files often requires specialized tools that can interpret the underlying data structures.
