What the functions of the main memory?
to store data
Where are global variable store?
Main memory (RAM).
What are the similarities between the working model of memory and the multi store model?
Both the working model of memory and the multi-store model involve the concept of separate memory systems for different types of information. They both propose that information is processed through different stages before being stored or forgotten. Additionally, both models emphasize the role of rehearsal in transferring information between memory stores.
Cache memory and register memory?
Register memory are smaller in size than cache memory and registers are faster than cache..Cache memory store the frequently used data from main memory..
Is cache memory necessary?
The cache memory is used to store the frequently used data in the main memory in order to avoid the elapse of the seek time taken to read that data in the main memory.. So, to improve the performance of a PC, its necessary to have cache memory.
What is a cache?
Answer:- The Cache memory is placed between the CPU and the main memory. It is a fast speed memory and is expensive and faster than the main memory. Cache memory is used to store the frequently accessed data of main memory. The instructions that are frequently used by the CPU are stored in the cache memory. It is used to reduce the average access time for address, instructions or data, which are normally stored in the main memory. Cache memory increases the operating speed of the system. But is much costlier than main memory. From economic considerations, the capacity of the cache memory is much less as compared to main memory..
Distinguish between primary memory and auxiliary memory?
the main memory is the central storage unit of the computer system. it is relatively large and fast memory used 2 store the programs and data during the computer operation.main memory communicates directly with the CPU. main memory includes RAM and ROMs. devices that provide backup storage are known as auxillary memory. auxillary memory are relatively slow in comparision to the main memory. auxillary memory includes flash memory,magntic disks and floppys. main memory is located inside the CPU but auxillary memory is located out the CPU. the main memory is the central storage unit of the computer system. it is relatively large and fast memory used 2 store the programs and data during the computer operation.main memory communicates directly with the CPU. main memory includes RAM and ROMs. devices that provide backup storage are known as auxillary memory. auxillary memory are relatively slow in comparision to the main memory. auxillary memory includes flash memory,magntic disks and floppys. main memory is located inside the CPU but auxillary memory is located out the CPU.
Is cache memory is main or sec memory?
cache memory is neither main memory nor second memory. DDR's are Main memory and Disk is second memory.
How do you store memory?
we store memory in the brain. It has grooves in it,which actually store it. If more number of grooves, more the memory power.
Main memory is used to store data permanently.?
No. It is usually used to help run the programs your are running at that moment and store other associated data.
Distinguish 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.
How is cache different from primary memory?
Cache memory is a memory that is used by CPU so that the average time to access the memory is reduced. It is a smaller and faster memory that stores copies of data which is used in frequently accessed main memory locations, On the other hand, Primary memory is the main memory of the computer. The processor can easily access, store and retrieve information from the primary memory. Primary memory has two types, Random access memory and read only memory.
