  • Basic of Mainframe
    Basic of Mainframe Mainframe computer Mainframe is a very large and expensive computer capable of supporting hundreds, or even thousands, of users simultaneously. In the hierarchy that starts with a simple microprocessor at the bottom and moves to supercomputers at the top, mainframes are just below supercomputers. In some ways, mainframes are more powerful than supercomputers because they support more simultaneous programs. But supercomputers can execute a single program faster than a mainframe. The distinction between small mainframes and minicomputers is vague, depending really on how the manufacturer wants to market its machines. Modern mainframe computers have abilities not so much defined by their single task computational speed (usually defined as MIPS ² Millions of Instructions Per Second) as by their redundant internal engineering and resulting high reliability and security, extensive input- output facilities, strict backward compatibility with older software, and high utilization rates to support massive throughput. These machines often run for years without interruption, with repairs and hardware upgrades taking place during normal operation. Software upgrades are only non-disruptive when Parallel Sysplex is in place, with true workload sharing, so one system can take over another's application, while it is being refreshed. More recently, there are several IBM mainframe installations that have delivered over a decade of continuous business service as of 2007, with hardware upgrades not interrupting service. Mainframes are defined by high availability, one of the main reasons for their longevity, because they are typically used in applications where downtime would be costly or catastrophic. The term Reliability, Availability and Serviceability (RAS) is a defining characteristic of mainframe computers.

  • Classification of Computers
    Classification of Computers Computer systems used for business purposes can be divided in to three classes: Microcomputers, Minicomputers and Mainframe computers. Though these divisions are loosely based on the size of the computer systems, there are no hard and fast rules for deciding exactly where one category ends and the next begin. Hence the largest minicomputer systems are often larger than the smallest mainframe computers. The “size” of a computer system is dependent on the size of a computer’s hardware configuration, the nature of its applications, and the complexity of its system software. This helps us to classify a system as a microcomputer, minicomputer or mainframe. Irrespective of size, all computers consist of two basic types of components. Those are processors and input/output (I/O) devices. The processor consists of three parts: the Central Processing Unit, or CPU, main storage and device controllers. The CPU executes instructions, main storage stores instructions and data processed by the CPU and device controllers let the CPU and main storage connect to I/O devices. Note: Though all computer systems consist of three basic components, the way those components are combined for a particular computer system varies depending on the system’s requirements. Microcomputer or Personal Computer Microcomputer is primarily intended for stand-alone use by an individual. Microcomputers are small, single-user systems which provide a simple processor and just a few input/output devices. This system consists of a processor with 2 or 4 GB of main storage, a keyboard, a display monitor, a printer, and a diskette drive with a capacity of 4GB and a 500 GB of hard disk.
