The 'select' system call is used in programming to monitor multiple file descriptors, waiting until one or more of them become 'ready' for some class of I/O operation. It is a crucial mechanism for implementing non-blocking I/O operations, allowing programs to efficiently manage multiple input/output streams without being constrained by blocking calls.

Input/Output Streams are mechanisms that allow programs to read and write data, facilitating communication between a program and external sources like files, networks, or other devices. They abstract the complexities of data transfer, providing a consistent interface for handling various data types and sources efficiently.
