Binary serialization is the process of converting data structures or objects into a binary format that can be easily stored or transmitted. This binary representation is more compact and efficient compared to text-based formats, making it ideal for situations where speed and size are critical factors. By serializing data into binary, it can be quickly written to disk or sent over a network without the need for additional parsing or conversion steps.

In binary serialization, each data element is encoded as a sequence of bits, which allows for precise representation of the original data structure. This makes binary serialization more suitable for complex data types and structures that may not easily translate to text formats. Additionally, binary serialization is often faster than other serialization methods, as reading and writing binary data requires fewer processing steps.

One of the main advantages of binary serialization is its platform independence, as the binary format can be read and written by different programming languages and platforms. This makes binary serialization a popular choice for data interchange between systems that may not share the same technology stack. However, it is important to note that binary serialization may not be human-readable, which can make debugging or troubleshooting more challenging compared to text-based serialization formats.
