What are the advantages and disadvantages associated with the process of binary data deserialization?

Binary deserialization is the process of converting binary data back into objects or data structures.

Advantages:

• High performance: binary data is usually more compact and processed faster compared to text formats.
• Smaller size: binary formats occupy less space, saving memory and bandwidth.
• Accurate data transfer: allows preserving exact values without loss, for example, for floating-point numbers.

Disadvantages:

• Security issues: binary deserialization can be vulnerable to attacks if data is not verified, which may lead to execution of malicious code.
• Portability: binary formats may depend on architecture (e.g., byte order, alignment), complicating exchange between different systems.
• Lack of readability: binary data is difficult to debug and analyze manually.

Example in C++ (simplified):

struct Data {
    int id;
    float value;
};

// Deserialization from binary file
std::ifstream in("data.bin", std::ios::binary);
Data d;
in.read(reinterpret_cast<char*>(&d), sizeof(d));
