Syöttötulostusvirtojen

Syöttötulostusvirtojen, often translated as input/output streams or I/O streams, are a fundamental concept in computer science and programming. They represent a sequence of data that can be read from or written to. This data can originate from various sources or be directed to various destinations. Common sources include files, keyboards, network connections, and memory buffers. Destinations can similarly be files, screens, printers, network sockets, or other memory locations.

The concept of streams abstracts away the underlying hardware details. Programmers interact with streams through a consistent interface, regardless of whether they are reading from a file on a hard drive or receiving data over a network. This abstraction simplifies the development process, allowing developers to write code that is more portable and less dependent on specific input/output devices.

Streams are typically categorized into input streams and output streams. An input stream is used for reading data, while an output stream is used for writing data. Many programming languages provide built-in libraries or classes to handle these streams. These libraries offer functions for reading individual characters, lines, or entire blocks of data, as well as for writing data in various formats. Error handling is also an important aspect of stream operations, as input and output operations can fail for numerous reasons.
