Question: Which Memory Has The Highest Cost Per Bit?

Is cache faster than 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..

Is cache memory faster than registers?

Cache is a smaller and fastest memory component in the computer. Registers is a small amount of fast storage element into the processor.

Which level of memory has the highest cost per bit?

register fileMemory. Computer systems have a hierarchy of memory, as shown in the diagram on the right. At the top is the register file in the CPU. This memory has the highest cost per bit, the smallest capacity, and the shortest access time.

What is cost per bit?

Cost per bit is a useful metric to capture costs associated with the delivery of data, and make comparison across technologies, operators, or markets. Yet cost per bit estimates cited as absolute values (e.g., $5/GB) can provide a good punch line, but they are often misleading or inaccurate.

Which one is the fastest memory?

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.More items…•

Which of the following memory is volatile in nature?

Most of the general-purpose random-access memory (RAM) is volatile.

Which of the following is a secondary memory device?

Typical secondary storage devices include magnetic tape drives, magnetic disk drives, compact optical disk drives, and archival storage devices such as disk jukeboxes.

Which of the following is not a primary storage device?

Random Access Memory (RAM) and cache are both examples of a primary storage device. The image shows three different types of storage for computer data. Primary storage’s key differences from the others are that it is directly accessible by the CPU, it is volatile, and it is non-removable.

Which memory is costly in terms of cost per bit?

As we move from bottom to top in the Hierarchy, the cost per bit increases i.e. Internal Memory is costlier than External Memory.

Which is the fastest and most expensive memory in memory hierarchy?

registersWe can arrange the different types of memory in a pyramid. At the top is the fastest, smallest, and most expensive memory, the registers. At the bottom, the largest, cheapest, and slowest memory, off-line archival storage (e.g. a tape library).

What characteristics of RAM memory makes it not suitable for permanent storage?

RAM is a non-volatile memory. It is the characteristic of ram memory makes it not suitable for permanent storage. RAM storage does not store data and work if there is no power. It is used for the permanent storage only if you have power for 24/7 throughout the year.

What is the fastest most expensive memory in your computer?

Cache memoryA 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.
