What are the largest memories of a PC?

because the ram has run out.
because it is subjected to light mechanical stresses
because the ram is running out
because it no longer uses the speed of the ram, but that of the hard drive, which is slower
because it takes up space
why does the fragmentation of large files occur into smaller files, arranged on different tracks? the read head then slows down when reading these scattered fragments in memory.
why is the speed of the disk used and not that of the ram?
because it behaves like a ram but is used only when the latter is full and there is too much information. as a result, the computer slows down
saturated with information
because the information is temporarily saved on the hard drive and therefore takes up space on the hard disk.

the rpm depends on the latency time.
from the size of the disk
from the diameter of the disk
air
from the diameter and from wear
from the number of discs and from the diameter
the diameter of the disk
A
from the sum of the seek time, the rotational latency time, and the transfer time.
from the diameter: the larger it is, the lower the speed will be

because electrons travel in series, minimizing interference.
because they are guaranteed by continuous cabling
because the electromagnetic fields of electrons do not interfere with their passage, slowing them down
because the bits arrive at the receiver sequentially, generating an electric/magnetic field lower than that generated by the parallel ide connections
because electrons flow in buses one after the other and are not subject to interference from magnetic or electric fields like in ides.
because the information (2-4 pins) arrives sequentially exerting a magnetic and electric field
because there is a weaker electromagnetic repulsion experienced by electrons
because the bits travel one after the other, without the electric and magnetic fields interfering with each other.
because the movement of charges is not hindered by the interference of the magnetic field
there is no interference from the electromagnetic fields of moving electrons

it means to delete the data.
clean up all existing files
delete the data
prepare a storage unit to accommodate files by creating grooves in the disk
create tracks by dividing them into sectors, with contiguous sectors forming clusters. the cluster is the minimum unit for file storage
trace a segment, with the head on the hard disk, that is, save a file.
to erase all of the data on the disk and prepare it for the usage of the computer
restore to factory settings
start writing information onto a blank hard drive, creating tracks, sectors, and clusters on each disk.
create tracks and clusters on a memory
