Which is lowest in memory hierarchy?

Most modern computer systems use a hard drive made of magnetic or solid state storage as the lowest level in the memory hierarchy (see Figure 8.4). Compared with the ideal large, fast, cheap memory, a hard drive is large and cheap but terribly slow.

Which of the following is the lowest in memory hierarchy?

Memory Hierarchy

  • Auxiliary Memory. Auxiliary memory is known as the lowest-cost, highest-capacity and slowest-access storage in a computer system. …
  • Main Memory. The main memory in a computer system is often referred to as Random Access Memory (RAM). …
  • I/O Processor. …
  • Cache Memory.

Which of the following is lowest in memory hierarchy Mcq?

5 . Which of the following is lowest in memory hierarchy?

  • Cache memory.
  • Secondary memory.
  • Registers.
  • RAM.
  • None of these.

Which is slowest memory?

A typical computer has 3 types of memory: Cache memory, Random Access Memory (RAM), and virtual memory. Cache is the fastest and most expensive, RAM is slower and less expensive, and virtual memory is the slowest and least expensive type.

Which is the top level memory in memory hierarchy?

The memory in a computer can be divided into five hierarchies based on the speed as well as use. The processor can move from one level to another based on its requirements. The five hierarchies in the memory are registers, cache, main memory, magnetic discs, and magnetic tapes.

What is memory hierarchy explain?

In computer architecture, the memory hierarchy separates computer storage into a hierarchy based on response time. Since response time, complexity, and capacity are related, the levels may also be distinguished by their performance and controlling technologies.

Which is the fastest memory device?

  • Fastest memory is cache memory.
  • Registers are temporary memory units that store data and are located in the processor, instead of in RAM, so data can be accessed and stored faster.

Which is the fastest memory Mcq?

Discussion Forum

Que. The fastest memory in a computer system is:
b. RAM
c. Cache
d. Hard disk

Which is the fastest storage unit in a usual memory hierarchy?

Answer. Register is the fastest storage unit in a computer memory hierarchy. Register is a part of the computer processor which is utilized to hold a computer instruction, perform mathematical operation as storage address or any other type of data.

Which register is memory pointer?

Stack registers in x86

In 8086, the main stack register is called stack pointer – SP. The stack segment register (SS) is usually used to store information about the memory segment that stores the call stack of currently executed program. SP points to current stack top.

Which is the most expensive memory?

The… Texas Memory Systems has developed a solid state disk system which performs 5 million I/Os per second. It costs $4.4m for 100 terabytes of storage.

Which is faster cache or RAM?

Since the cache memory is faster than RAM, and because it is located closer to the CPU, it can get and start processing the instructions and data much more quickly. The same procedure is carried out when data or instructions need to be written back to memory.

What type of RAM is found in the most expensive systems?

SRAM (pronounced ES-RAM) is made up of four to six transistors. It keeps data in the memory as long as power is supplied to the system unlike DRAM, which has to be refreshed periodically. As such, SRAM is faster but also more expensive, making DRAM the more prevalent memory in computer systems.

Why is primary memory faster than the secondary memory?

Primary memory or RAM is faster to access because it is wired directly to the processor. It is used by the system to perform operations while programs are running. Secondary memory is usually somewhat slower and is used for permanent storage of information.

What is the goal of memory hierarchy?

In Computer Architecture, Memory hierarchy is a hierarchy of memory and storage devices. Memory Hierarchy Diagram. It’s purpose is to minimize the average access time of the entire memory system.

Which type of memory comes at the top of the memory hierarchy and which at the bottom?

Auxillary memory access time is generally 1000 times that of the main memory, hence it is at the bottom of the hierarchy. The main memory occupies the central position because it is equipped to communicate directly with the CPU and with auxiliary memory devices through Input/output processor (I/O).
