Which memory is expensive than RAM?
In addition to being the fastest option, SRAM is much more expensive than DRAM, so it is mainly used as the cache memory inside the integrated circuit that is a computer’s CPU..
Is ROM or RAM faster?
RAM is a high-speed memory, with reading-write operations, happen at a fast pace whereas ROM is slower speed memory, which is less prone to modification and can be done via an external program.
What are the two types of memory?
There are two major categories of memory: long-term memory and short-term memory.
Why primary memory is more expensive than secondary memory?
As soon as the computer is switched off the contents of the primary memory is lost. You can store and retrieve data much faster with primary memory compared to secondary memory. Primary memory is more expensive than secondary memory. Because of this the size of primary memory is less than that of secondary memory.
What is the 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.
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.
What is ROM in memory?
9 Oct 2018. Read-Only Memory (ROM), is a type of electronic storage that comes built in to a device during manufacturing. You’ll find ROM chips in computers and many other types of electronic products; VCRs, game consoles, and car radios all use ROM to complete their functions smoothly.
Which is a volatile memory?
Volatile memory, in contrast to non-volatile memory, is computer memory that requires power to maintain the stored information; it retains its contents while powered on but when the power is interrupted, the stored data is quickly lost. … Most of the general-purpose random-access memory (RAM) is volatile.
Which 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 memory required more cost?
The most expensive memory is in-CPU memory such as registers and internal instruction queues. While it is difficult to calculate the price, it is clearly more than tens of dollars per kilobyte.
Is cache memory permanent?
RAM is temporary memory used to store data that the computer is currently using. RAM is volatile since all information is cleared from the RAM once the computer is restarted. Cache memory: Cache memory is also called CPU memory. … From the disk cache, the data is written to the hard drive, which stores it permanently.

What is secondary memory?
Secondary memory refers to storage devices, such as hard drives and solid state drives. It may also refer to removable storage media, such as USB flash drives, CDs, and DVDs. Unlike primary memory, secondary memory is not accessed directly by the CPU.
Which memory has highest storage capacity?
Storage Capacity of Floppy Disc = 1.44 Megabytes. Storage Capacity of CD-ROM = 650 Megabytes (Approx.).
