Bytestreams

A bytestream is a sequence of bytes, typically representing data transmitted or stored in a sequential manner. It is a fundamental concept in computer science and is used extensively in various applications, including file I/O, network communication, and data serialization.

Bytestreams can be thought of as a continuous flow of bytes, where each byte is an atomic unit of data. This flow can be read from or written to, allowing programs to process data sequentially. When reading from a bytestream, data is consumed byte by byte, and when writing, data is appended to the stream.

In programming, bytestreams are often implemented as abstract data types or interfaces that provide methods for reading and writing bytes. These implementations abstract away the underlying details of how the data is stored or transmitted, allowing developers to focus on the data itself. Common operations on bytestreams include reading a single byte, reading multiple bytes into a buffer, writing a single byte, and writing a buffer of bytes.

Bytestreams are versatile and can represent various types of data, such as text, images, audio, or executable code. The interpretation of the bytes within a bytestream depends on the context and the protocol or format being used. For example, a bytestream representing text might be interpreted according to a specific character encoding like UTF-8, while a bytestream representing an image would follow a defined image file format. The concept of bytestreams is crucial for handling raw data in a structured and manageable way across different systems and applications.
