| I am sure that you might have heard about | | | | with the highly flexible IBM system/360 which used |
| mainframes and the career prospects they offer. Do | | | | microcode to implement the machine instructions. The |
| you know about the specialty of mainframes? | | | | last in the spectrum is the Z series, introduced in the |
| Mainframes are very large computers mainly used for | | | | 2000s, equipped with massive scalability, better |
| running mission critical and complex applications | | | | security and resiliency, intelligent workload |
| involved in activities like bulk data processing, financial | | | | management and business integration on a virtualized |
| transactions etc. | | | | platform. |
| The huge servers are capable of supporting immense | | | | So many speculations were made about the future |
| number of applications and input/output devices to | | | | of the mainframes so far. The truth is that they will |
| simultaneously serve any number of users by the | | | | not become obsolete for a reasonably long time. The |
| partitioning of resources. That is, it serves as a | | | | markets see an ever-time improvement in the sale of |
| centralized depository of data which is connected to | | | | mainframes and boom in the training. This is because |
| the users through work stations or terminals. | | | | mainframes are still unsurpassable in their reliability and |
| The origin of the mainframe can be traced back to | | | | stability in processing information. No technology |
| the 1950's which saw the emergence of the IBM 700 | | | | might have undergone such a lot of evolutionary |
| 7000 series. Since then there has been a series of | | | | changes as mainframes had. They win over their |
| products evolving to accommodate the user | | | | competitors by the continuous evolution of their |
| requirements. Some of the initial drawbacks of | | | | architecture to meet the demands of the user |
| mainframe that had been pointed were the lack of | | | | network at the same time maintaining compatibility |
| flexibility and the high cost. Thus the IBM came up | | | | with the existing applications. |
