Which memory has the slowest CPU access speed in the computer?
This article is about which memory has the slowest access to CPU on your computer. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.
In the computer, the memory with the slowest CPU access speed is "hard disk", and the order of CPU access speed is "CPU cache > memory > hard disk". Hard disk is one of the main storage media of computer, which consists of one or more aluminum or glass discs covered with ferromagnetic materials. The hard disk can also keep the data from being lost after the power is off.
The operating environment of this tutorial: windows7 system, Dell G3 computer.
Usually, the storage media of a computer system include Cache, memory, magnetic tape and hard disk, of which the slowest access speed is "hard disk".
The order of CPU access speed is: CPU cache > memory > hard disk. The speed of accessing the cache is the fastest and the access to the hard disk is the slowest.
Hard disk is the most important storage device of computer. The hard disk (Hard Disk Drive, HDD full name Winchester hard drive) consists of one or more aluminum or glass discs. These discs are covered with ferromagnetic material.
The vast majority of hard drives are fixed and permanently sealed in the hard drive. The early hard disk storage medium was replaceable, but today's typical hard disk is a fixed storage medium, sealed in the hard disk (except for a filter hole to balance air pressure). With the development, removable hard disk also appeared, and more and more popular, more and more kinds. The hard drives installed on most microcomputers are called "Winchester hard drives", or "warm disks" for short, because they use winchester technology.
