Let us understand the characteristics of mainframe operating systems.Characteristics of Mainframe operating systemsThe characteristics of Mainframe operating systems are explained below −These systems have a large number of CPUs each having great processing power. All the CPUs with great processing power are combined into the Mainframe which as a result has the greatest processing power.The memory of the mainframe operating system is very large. It can even be about more than 8GB.Increased Performance/throughput as task load is shared: Mainframes systems share the task load among different processors and input/output devices. Thus, the processing power and efficiency increases multifold.Supports Time Sharing ... Read More

Inside the computer system the memory hierarchy is arranged from fastest to the slowest as given below −RegistersCaches memoryMain or Primary MemorySecondary MemoryThe memory hierarchy is depicted in the diagram given below −Let us discuss about each memory in detail.RegisterRegisters are very high speed memory, which is present inside the CPU. It is a temporary storage device that means it stores the data temporarily. Generally, they create a general purpose register file to store data. The register file capacity is 32 data words, and each register can be read or written from within a single clock cycle.Cache MemoryThe cache memory ... Read More
