Data cable, its function is to connect
mobile equipment and computer, in order to achieve data communication purpose.
Popular point said, it is an access tool which links computers to transfer
fluid picture such file. With the development of electronics industry change
with each passing day now, data cable has become a part which we cannot miss in
our life, especially iPhone
data cables.
As an iPhone
5 cable wholesale supplier, Goodscool sum up three questions about it.
Q: Is there a connection between data cable
transmission rate and its thickness? If there is any relationship; is it in
direct proportional relationship or reciprocity relationship?
A: They do not have direct connection.
There is some amount line in it. Thick line is useless. USB port and data line
port limit the speed of data transmission.
Q: Which is faster? Multimedia card reader
transmission rate or data cable transmission rate?
A: It depends on the card reader and card
interface velocity. USB
2.0 interfaces data cable is 40 times faster than USB1.1 card reader,
USB 3.0 card reader is 10 times faster than USB 2.0.
Q: Why the literacy rate of internal memory
is much faster than disk?
A: Because of the hard disk is the
mechanical storage device which reading and writing data by blanks and head of
the mechanical movement; memory is a semiconductor memory device which is the
buffer between the CPU and disk data.
CPU only read memory data. This memory becomes a bridge role.
Memory data will disappear once shutdown. And
as storage space, hard disks data will always exist if not appear problem.
