Hello students, as here is we are providing all the answers.
00:05
So the first question is as to draw diagram of the computer memory hierarchy.
00:12
So here is the computer memory hierarchy, hierarchy where the computer memory hierarchy consists of the multiple levels of the memory each with a different x speeds, with their capacities as well as with their cost.
00:37
So this hierarchy includes as the register, cache memory, main memory ram, also with the virtual memory as the flash memory and the secondary memory that is the hard disk and the last here it includes the tape drivers as the magnetic tapes.
00:56
So this initial two stages are our internal storage, the main memory are its primary storage whereas the flash memory and the hard disk it is a secondary storage and the ternary storage is a magnetic tapes.
01:11
So this is how the diagrammatically representation of this computer memory hierarchical.
01:19
The second is the main types of the memory technology and the performance are the main memory technology includes the sram, sram that is the static, that is the static random, random access memory, access memory whereas it is the faster and more efficient used in the ram and cache memory.
01:57
The next is the dram, dram where it is the dynamic random access memory, dynamic random access memory, access memory.
02:17
So it is the slower but most more affordable using the main memory as the ram.
02:23
So the third is the effect of the memory latency on the running time.
02:28
The memory latency refers to the time it takes to access the data from the memory.
02:34
So high memory as the high memory latency leads to longer execution time as the computer spends the more time for the data.
02:46
So it can be bottlenecked of program performance and the as the slowdown the cpu speed memory.
02:53
So this is what the memory latency refers to the it's taking an access the data from the memory.
03:01
As the next is the next is the use of the caching memory and the virtual memory to the reduce the memory latency.
03:12
Caching memory as well as the and the virtual memory, virtual memory to reduce the latest memory latency.
03:24
As the caching memory stores the frequent used data to close to the cpu for the faster access, it reduce the more latency by providing the small but alter the fast storage buffer.
03:37
Data is fetched from the main memory to caching and a substituent request are served from the caching if the data is available...
