can you explain, the connection between cellphone to the memory of the computer in transferring data.?

Question

this is through using data cable.how crucial is data cable in transferring data.

Answer 1

Data cable is an essential part of connectivity for ur phone. Even though you can connect and transfer data using bluetooth or infrared port etc yet a data cable is much fast and besides not all phone softwares support backup of ur contacts etc using bluetooth or IR.
You can easily tranfer songs, files or even backup stuff in a blink.
Most phones from nokia are now running on a Symbian OS which tend to crash offen if u install 3rd party softwares hence taking regular backups would help avoid situations whereby all data is lost permanently...

Answer 2

the data cable is your medium, but is not the only option as you can also use bluetooth or IR if you have them. think of it as a bridge -- the car is your data and it has to transfer from one point to another.
