Computer algorithms: The process of converting input into output as needed in one step
Oh,no!
You should first describe the data store and store it on disk:
Data storage for computers: Usually our computers operate in 10 binary, such as: 4, and the computer is calculated by means of 2 binary: for example
2 The internal ID of the computer is: 0010
Since it is 2 binary, the result ID 0100 when the + method is performed
Four-bit ID: 8 4 2 1
So the result is 4.
How the computer is stored on disk: a mechanical hard disk storage area consists of hundreds of G bytes, each corresponding to the computer's smallest cell magnetic particles, here by changing the way magnetic particles are judged as 0 or 1
The principle of data recovery, such as a flash memory card deleted a picture, a JPEG image is usually composed of a few megabytes, the computer just upset the first thousands of bytes of storage to put this area in a stateless, writable state,
If we restore this area, we'll be able to read the image again.
