The hardware required to perform a server function can range from little more than a cluster of rack-mounted personal computers to the most powerful mainframes manufactured today a mainframe is the central data repository, or hub , in a corporation's data processing center, linked to users through less powerful devices such as workstations or. A mainframe is a computer that can only be accessed from a terminal the mainframe is essentially just a regular computer, except multiple people can be logged on and use the computer at the same time. Mainframes are used for problems which are limited by data movement in input/output devices, reliability and for handling multiple business transactions concurrently.
Mainframes are very large, very expensive supercomputers that were used "back in the day" (and are still used by companies who haven't replaced/upgraded them yet) as servers desktop-type technology wasn't powerful enough to provide services for a large-scale network, so these larger, more powerful computers were necessary. A mainframe is designed for processing large amounts of information by the use of batch transaction processing it particularly works well at running scalable software and dealing with massively parallel operations. Mainframe computers, also known as big iron, power things from credit card processing to airline ticketing how do they work, and what makes them different from other large-scale devices like.
Contents covered by seminar • introduction a personal computers b mainframes c super computers (with their configurations as comparison. Best answer: personal computers os are very fixed, the computer needs a keyboard, a mouse and one processor and at least one monitor and a primary hard drive while mainframes require very flexible structure a mani frame can have several hard drives and several processors that cooperate to do the job. These computers came to be known as desktop computers, or personal computers (pcs) a typical pc contained the same basic components as a mainframe computer (cpu, ram, storage, etc) but at a fraction of the size and cost.
The basic premise is that though mainframes technology is being replaced by much more capable personal computers there is still a need for the computing power of the mainframe especially true is that mainframe computers still have the edge over client/server technology when it comes to storage and relative ease of administration. Whereas a personal computer operates at 3-4 mips, a mainframe computer processes at 70-100 mips one surprising fact about mainframe computer is they can run several operating systems at once the very first operating system for the mainframe computer was the z/os which was invented by ibm. A mini-computer is similar to mainframes and micro computers it kind of fills in a gap between micro computers and mainframes there are more processors than a mc, but fewer than a mainframe.
Supercomputer and mainframe computers are the most powerful computers but they can be distinguished by the tasks they perform on the one hand where supercomputer focuses on a fast computation of complex mathematical operations. A personal computer (pc) is a multi-purpose computer whose size, capabilities, and price make it feasible for individual use pcs are intended to be operated directly by an end user, rather than by a computer expert or technician. Personal computers vs mainframes pos355 6/25/2012 usually the obvious difference of a pc and mainframes is the size mainframes are usually much larger room-sized units but today they can be as small as a desktop pc. Personal computers v mainframes the information systems backbone of many companies is their mainframe computer the mainframe computer is a large centrally located machine capable of processing multiple very large transactions at the same time.
A mainframe computer is a scaled-up version of a regular computer with increased performance and processing power they are usually very large and serve many users simultaneously, being more specific to corporate environments. Personal computers are typically used at home, at school, or at a business mainframe a mainframe computer is a large, powerful computer that handles the processing for many users simultaneously (up to several hundred users. Mainframes and personal computers have changed drastically over the years but their core functions and systems have stayed the same the mainframe is used.
