The reasons for mainframe use are many, but most generally fall into one or more of the following   categories:   Reliability, availability, and serviceability(RAS)  Security  Scalability  Continuing compatibility Let us look at each of these categories in more detail. The reliability, availability, and serviceability (RAS) of a computer system have always been important factors in data processing.  Ideally, RAS is a central design feature of all aspects of this computer system, including the applications. RAS is ubiquitous in the mainframe. Reliability:- The system’s hardware components have extensive self-checking and self-recovery capabilities. The system’s software reliability is a result of extensive testing and the ability to make quick updates for detected problems. Availability:- The system can recover from a failed component without impacting the rest of the running system. This applies to hardware recovery (the automatic replacing of failed el...

Ø   Mainframe is a server type computer. Ø   They are data servers that are designed to process up to 1 trillion web transactions    daily with the highest levels of security and reliability.     Ø   Mainframes can handle vast amounts of data, support thousands of users simultaneously it can run for 24 hours with zero down time, making them essential for  industries like banking, insurance, healthcare, and government. Ø Key features include extensive input/output (I/O) capabilities, robust backup and recovery systems, and advanced virtualization capabilities.   Ø   Mainframes are the super computers that are better than normal computer 1000 times that can perform milli, Billi, trill instructions per second.   youtube Mainframe_Girls
