The term used to describe the concept of moving the memory to hard drive is termed as Paging out. Points: 8. The relationship between the main, cache and virtual memory in the Windows Operating Systems OS goes like this: The first difference lies in the size.
It is the Physical memory which is installed in the computing system. This is the part of memory where most of the processing work is done. The maximum memory of the RAM depends on the combination of hardware and the version of the Operating System. Cache memory This memory covers a good range of items. The Processors will have multiple cache memory types which are usually known as level 1, 2 or 3.
A Processor can have all of these three types installed in it. The Hard drives use the cache memory to speed up the data transfers. The Hard drive controllers too use the cache memory. The Network Cards utilize the cache memory for high output. These cards are generally found on few servers mostly for gaming purpose. Virtual memory The first difference between Virtual Memory and the two others is that, virtual is not like the physical RAM.
The Virtual memory in a Windows Operating System is generally referring to a kind of memory that can be temporarily moved from the RAM to a hard drive or a flash memory device. In that case the hyper-visor will manage all the memory by virtualizing them and assigning them to virtual machines. There are systems or Operating Systems which can set the pools of physical memory setting them as virtual memory for specific types of tasks.
Points: 6. Main memory 1. It is a volatile memory. Speed:- Much faster than Hard disk. The time required to access data placed anywhere within RAM is same.
Speed counted in Giga Byte per second. Size:- Much smaller than Hard disk. Therefore, the programs that should execute are brought into the RAM so that they can be executed faster. It takes only a short time to access data from the RAM when compared to accessing data from the secondary storage medium such as hard disk , and solid state drive.
It is a volatile memory , which requires a continuous flow of power to maintain the data. Interruptions or power failures can delete the data stored in the RAM. It can have bit or bit data paths. This refers to the number of bits that are transferred in 1 clock cycle. A computer with more RAM will have a higher performance. The DRAM consists of a capacitor and a transistor. The capacitor can change, discharge and represent the logical one and logical zero.
There is a leakage current due to the capacitor, and it causes the capacitor to lose charge. This can delete the content in DRAM. Therefore, DRAM requires constant refresh cycles to retain data. Moreover, SRAM contains flip-flops to store data. Mail us on [email protected] , to get more information about given services.
