What is the difference between cache memory and primary memory?
Primary cache is closest to the processor. Secondary cache is located at the second closest place of the processor. Main memory is also known as Random Access Memory (RAM)….
| Main Memory (RAM) | Cache Memory | |
|---|---|---|
| Component | It is a part of the hard drive (secondary storage) | Located on the processor itself |
Where is cache memory stored?
The cache memory is located very close to the CPU, either on the CPU chip itself or on the motherboard in the immediate vicinity of the CPU and connected by a dedicated data bus. So instructions and data can be read from it (and written to it) much more quickly than is the case with normal RAM.
What is stored in primary memory?
Primary storage (also known as main memory ) is the component of the computer that holds data , programs and instructions that are currently in use. Primary storage is located on the motherboard . This gives the processor fast access to the data and instructions that the primary storage holds.
Is cache memory a primary memory?
Memory system can be divided into 4 categories: CPU register. Cache memory. Primary / Main memory….2. Secondary Memory / Mass Storage:
| Sr.No. | Primary memory | Secondary memory |
|---|---|---|
| 7. | Examples: RAM, ROM, Cache memory, PROM, EPROM, Registers, etc. | Examples: Hard Disk, Floppy Disk, Magnetic Tapes, etc. |
Cache memory increases the accessing speed of CPU. It is not a technique but a memory unit i.e a storage device. In cache memory, recently used data is copied….Difference between Virtual memory and Cache memory:
| S.NO | Virtual Memory | Cache Memory |
|---|---|---|
| 3. | The size of virtual memory is greater than the cache memory. | While the size of cache memory is less than the virtual memory. |
What is primary memory secondary memory?
Primary memory is the main memory of the computer which can be directly accessed by the central processing unit, whereas secondary memory refers to the external storage device which can be used to store data or information permanently. …
What is memory difference between primary and secondary memory?
Computer memory is categorized into primary and secondary memory. While primary memory is the main memory of the computer which is used to store data or information temporarily, whereas secondary memory refers to external storage devices that are used to store data or information permanently.

What are the 3 differences between cache and virtual memory?
What is difference between cache memory and virtual memory?
Cache memory is a memory unit and is very fast to access. Virtual memory is a technique and involes hard disk and is slower to access. CPU and related hardwares manages cache memory. Operating System manages virtual memory.
