The larger the hard disk cache, the faster it will boot up and the faster it will be read and written.
In addition, after installing the system, the system will open up a place for the hard disk as virtual memory by default, and run it when the physical memory (that is, the computer memory) is not enough, but now the physical memory is getting bigger and bigger, and there is no longer much need for virtual memory.

Anonymous users2024-02-11To put it simply. The hard disk is where the software is stored.
Memory is used to store data caches.
All you need for the size of the installation is the hard drive.
All you need to run your game is memory.

Anonymous users2024-02-10The hard disk is called the cache. It's just that when there is too much data and it is not saved to the hard disk so quickly, put it in the cache for a while.
Memory is where the CPU runs and stages instructions when processing tasks.

Anonymous users2024-02-05The so-called memory of the hard disk refers to the storage space of the hard disk, and everything in your computer is stored in the hard disk.
Memory, on the other hand, is the data that the computer uses for real-time calculation and storage, which is borne by the memory module.

Hard disks have hundreds of gigabytes

Anonymous users2024-02-03First, the nature is differentMemory is the workplace of the computer; Hard disks are used to store information that is not in use for the time being.
Second, the production materials are differentMemory is made of semiconductor materials; Hard drives are made of magnetic materials.
3. Information retention is differentInformation in memory is lost with a power outage; The information on the hard drive can be stored for a long time.
Fourth, the capacity is differentGenerally, the capacity of hard disks is 1TB, that is, 931GB; Whereas, the memory is generally 6GB.
Fifth, the role is differentMemory is a buffer between the CPU and the hard disk data, and the CPU can only read the data in the memory. In this way, memory becomes a bridge; Whereas, hard disks are used as storage space.
The hard drive is inside the computer.
A floppy disk is a disc-like disc that can be carried. But now there are fewer people who use floppy disks! >>>More
Memory is the CPU, hard disk and temporary storage space when the program is running, it is a very important computer component, if the computer memory is too small, it will cause the temporary space when the system is running is not enough, thenThe role of computer memoryWhat are they? What is the right amount of RAM on my computer? Below we will give you a detailed answer, I hope you can help after reading it. >>>More
1. CPU cache (cache memory) is located in the temporary memory between the CPU and the memory, its capacity is smaller than the memory but the exchange speed is faster. The data in the cache is a small part of the memory, but this small part is about to be accessed by the CPU in a short period of time, and when the CPU calls a large amount of data, it can be called directly from the cache without memory, thus speeding up the read speed. It can be seen that adding a cache to the CPU is an efficient solution, so that the entire internal memory (cache + memory) becomes a high-speed storage system with both cache and large capacity of memory. >>>More
