Bytes and byte arrays are fundamental concepts in computer science, particularly in the fields of data storage, transmission, and manipulation. A byte is a unit of digital information that most commonly consists of eight bits. It is the smallest addressable unit of memory in many computer architectures. Bytes are used to represent characters, numbers, and other data types in computing systems.

A byte array, also known as a byte buffer or byte stream, is a contiguous block of bytes stored in memory. It is a common data structure used for handling binary data, such as files, network packets, and other forms of raw data. Byte arrays are particularly useful in programming languages that provide low-level access to memory, such as C, C++, and Java.

In high-level programming languages, byte arrays are often used to represent sequences of bytes, such as strings of text or binary data. For example, in Python, a byte array can be created using the built-in bytearray type, which allows for efficient manipulation of binary data.

Byte arrays are essential for various applications, including file I/O operations, network communication, and cryptographic functions. They provide a flexible and efficient way to store and process binary data, making them a crucial component in modern computing systems.
