Anonymous users2024-02-05Memory is a type of memory. It doesn't store data for a long time.
Hard drives can be stored for a long time. Probably compare:
Memory hard disk.
The speed is fast and slow.
The capacity is small and large.
Long-term storage is not possible Yes.
Why hard drives? Your software, etc., needs to be stored on your computer for a long time.
Don't want a hard drive? OK. You can start and run with floppy disks, USB sticks, and optical discs. But inconvenient.
To put it bluntly, a hard disk is a storage medium.
Why memory? Don't memorize lines?
Memory is mainly used to increase the speed of the software. Don't memorize, theoretically possible.
Do you want your machine to run like a snail? Please remove the memory.
But in fact, without memory, your machine can't run? why？That's how it was designed.
In addition, there is cache, which is cache.
For example, CPUs generally have L1 and L2 caches.
They are also meant to increase speed.
Cache, memory, and hard disk form a storage layer.
It solves the contradiction between speed and capacity.
So you can trade a lower price for a higher speed.

Anonymous users2024-02-04512 megabytes is physical memory, and the "RAM" that experts say refers to the memory module plugged into the motherboard. Hard disks are now mainstream 120G (120 Gigabit (160 Gigabit) and so on. The relationship between memory and hard disk is equal to the relationship between the factory and the warehouse, the larger the factory, the more things can be processed at the same time, and the larger the warehouse, the more items can be put down.

Anonymous users2024-02-03The 512 memory you are talking about is a place where the data is stored temporarily when the machine is running. When the power goes out, it's gone.
You're asking about hard drives. Not a concept.
Hard disks are generally used to store data and will not disappear due to the power failure of the machine.

Anonymous users2024-02-01Memory is used by the system to store files temporarily. The one you're talking about is a hard drive.
Two different pieces of hardware.

Anonymous users2024-01-30You're confusing the concepts of memory and hard drive capacity.
Your memory is only 512, and it's normal to have half of it left after entering the XP system. >>>More
It's useless to add memory, and if the processor and graphics card are not powerful, it's better to change the processor and graphics card.,If you don't have that plan, you can also add a memory, the effect is more obvious, but it's not much faster, because playing games mainly depends on the graphics card and CPU.
This,I have this situation.,Landlord,It should be a USB flash drive virus.,This computer antivirus generally can't be detected.,There's mobile phone software to do it.,But I forgot.。 That is to say, there is a file that overwrites your original file, you can't find the original file, but you can still find it with XP Manager, you can use XP Manager to delete the U disk virus file that overwrites your file, but the virus can't be deleted. >>>More
I sweat, don't talk nonsense about the one who doesn't know on the first floor. >>>More
If there's a problem, let's kill the virus.
