∙ 11y agomemory unit is an essential component in any digital computer since it is needed for storing program and data.A very small computer with a limited application may be able to fulfill is intended task without the need of additional storage capacity.

∙ 12y agoThe total memory capacity of a computer can be visualized by the hierarchy of components.This hierarchy system consists of all storage devices employed in a computer system.
The system can visualized three levels.
At the bottom level there is auxiliary memory. It is slow but due to low cost it present in large volume.It is not directly connected with the CPU.
At the second level there is a main memory. It is also called central memory as it is directly connected with CPU. The data and programs are currently needed by CPU, reside in the main memory.
At the top levels there is a very special high speed memory called cache that provide the speed that are comparable to the speed of CPU.

Need for memory Hierarchy?
memory is required to store the data or any information.but the usual computers have very less memory space in them. so to increase the performance of your computer and to access it on a faster rate we need memory hierarchy.
Which memory occupies top position in memory hierarchy?
Processor registers occupy the top most position in memory hierarchy. They provide high-speed storage space and fast access to data.
What are the principals and benefits of memory hierarchy?
mc....kutta
Where does most data go first within a computer memory hierarchy?
RAM (Random Access Memory).
Where does most data go first with in computer's memory hierarchy?
RAM
What characterstic distinguish the different element of memory hierarchy?
perfomance and size
What is a design objective of memory hierarchy?
One design objective of memory hierarchy is to balance resposne time and performance against each other, so that the response time of an operation minimally impacts computer performance.
What component has the fastest speed on computer?
Register. The memory hierarchy in the decreasing order of speeds: 1. Register 2. Cache 3. Main memory 4. Disks 5. Auxiliary memory
What characteristics distinguish the various elements of a memory hierarchy?
Registers >> Cache >> Main Memory >> Magnetic disk >> Magnetic tape • As one goes down the hierarchy, the following occur: a . Decreasing cost per bit b . Increasing capacity c . Increasing access time d . Decreasing frequency of access to the memory by the processor
Why is there a memory hierarchy instead of having a single memory?
Well, from what I can discern is that it is related to science. It appears that it pertains to the metric system but uses base-8 instead
With the help of a diagram explain memory hierarchy that exist in a computer system?
Memory hierarchy measures a computers performance issues. A general hierarchy would reflect the following. Internal ; processor registers and cache, main; ram and controller cards, on-line mass storage and online bulk-storage.
Draw the block diagram of ram and explain its operation?
Memory is technically any form of electronic storage. Personal computer system have a hierarchical memory structure consisting of auxiliary memory (disks), main memory (DRAM) and cache memory (SRAM). A design objective of computer system architects is to have the memory hierarchy work as through it were entirely comprised of the fastest memory type in the system.
