Explanation:
<em>Mainframes</em> are typically identified by their big size, high reliability, and massive processing power. One mainframe can replace a lot of small servers (running to hundreds) and work efficiently. Mainframes emphasize throughput computing because they can manage many high volume input/output (I/O) and can run multiple instances of Operating Systems (OS) concurrently.
