hi…..dear engineer frnds.

 i am a student of electrical engineering.

i just wana know about all that are present in nature/atmosphere..and in anvirnment.

1.- when we delet any data in MICRO-SD card..what hepns with the deleted data ?
where the go?

 

2.- how the data can save for long time in MICRO-SD cards and in USB-PORTAL.?

Hi Ram Kishore,

Nice self introduction.

I believe the data won’t go anywhere, it just remain where it was but waiting to get overwritten. That’s why we are able to recover the data using some software, eventhough the memory card shows lot of free space.

thank you for replying.

 but i think…. according my-self theory-

that the data simply write on a metalic plate in the codeing language….and that time the decoding also storing in that plate{ micro SD card/USB card}. when we wanat to remove that data.. use the decoding and they decode the data…and make nutralisation on the plate.

and the plate is ready to store new data. is it rong?

Hello,

 

 

Any data in computer or any digital device are stored data in the form of digital bits (Logic 0 or Logic 1) and these digital bit are stored in digital memory like combination of flip flop. MicroSD card, Pen Drive etc. are contain these bit storing digital memory, and it has implemented using LSI or VLSI technology.

 

1) When you delete any data then the part of the memory are cleared. and store any random data, these random data are treated as free space of memory.

 

2) Some digital memory have the capability to store the data after removing the power supply (non volatile memory).So, your data are stored for a long time.
