Stream

In the context of programming, a stream is an abstraction that represents a sequence of data elements made available over time. Streams are used to read from or write to data sources such as files, network connections, or memory buffers. They provide a way to handle input and output operations in a consistent and efficient manner.

1. Types of Streams
   • Input Streams: Used to read data from a source. For example, reading data from a file or receiving data over a network connection.
   • Output Streams: Used to write data to a destination. For example, writing data to a file or sending data over a network connection.
2. Stream Operations:
   • Reading: Extracting data from an input stream
   • Writing: Sending data to an output stream
   • Seeking: Moving to a specific position within a stream (supported by some streams)
3. Stream Classes in .NET:
   • FileStream: Used for reading from and writing to files
   • MemoryStream: Used for reading from and writing to memory buffers
   • NetworkStream: Used for reading from and writing to network connections
   • BufferedStream: Provides a buffering layer for another stream to improve the read and write performance
   • StreamReader and StreamWriter: Used for reading and writing text data
