What is meant by memory hierarchy? Is it possible to have a computer system without any secondary storage? Explain your answer.

What is Memory Hierarchy


Memory Hierarchy is the way in which different type of memory is arranged according to size, cost and speed. 

Computer systems can be constructed without secondary storage. There are many computer systems without secondary storage.

An EPROM can be used to used to do initial activities (like booting) when powered ON. Programs can be entered into RAM by typing in and can be executed. Only problem is backup of program and data is not possible normally. In many computer systems EPROM'S are used to as secondary memory.

Memory Hierarchy in Computer Architecture


In the design of the pc system, a processor, also as an outsized amount of memory devices, has been used. However, the most problem is, these parts are expensive. therefore the memory organization of the system are often done by heart hierarchy. it's several levels of memory with different performance rates. But of these can supply a particular purpose, such the time interval are often reduced. The memory hierarchy was developed depending upon the behavior of the program. this text discusses an summary of the memory hierarchy in computer architecture.

Memory Hierarchy in Computer Organization


The memory hierarchy design during a computing system mainly includes different storage devices. Most of the computers were inbuilt with extra storage to run more powerfully beyond the most memory capacity. The designing of the memory hierarchy is split into two types like primary (Internal) memory and secondary (External) memory.

Primary Memory

The primary memory is additionally referred to as internal memory, and this is often accessible by the processor straightly. This memory includes main, cache, also as CPU registers.

Secondary Memory

The secondary memory is additionally referred to as external memory, and this is often accessible by the processor through an input/output module. This memory includes an optical disc , magnetic disc , and mag tape.
