Fin366 - PC/Mainframe Paper
With the advancements in PC technology over the years mainframes have become a topic not a widely discussed anymore, but they are still being used by companies that can afford them. Mainframes and PCs accomplish the same tasks but they work in different ways. Mainframes are large high-performance computer systems that are usually used for large scales computing purposes such as, processing census data, or enterprise data. The resources of mainframes can be accessed by many users. A PC is a small sized personal computer that is built for use by a single end-user. The following paragraphs will compare and contrast the costs, size, operating systems, programing, and maintenance aspects of mainframes and PCs.
Fin 366 - The performance of a mainframe is much greater than that of a PC. According to The History of Computing Project (2011), mainframes have one to 16 CPU’s (newer mainframes have more). The average PC has only one CPU with a single core to multiple cores which act as individual processors. According to The History of Computing Project (2011), IBM’s eServer zSeries 890 mainframe can host up to 32GB of RAM. The memory of the modern day PC is typically maxed out at 16GB of RAM.
Pos355 - The History of Computing Project (2011), mainframe processing power ranges from 80 to over 550 Mips. The processing power of PC’s is based on factors such as processor speed, the amount and speed of RAM, and the front-side bus. Mainframe components such as RAM, storage devices, and I/O components are often housed in different cabinets of the system, while all of these components are stored in a single compact housing of the PC. According to The History of Computing Project (2011), mainframes separate processes for program management, task management, job management, catalogs, inter address space, serialization, and communication.
