ROM data cannot be updated at will, but can be read and written at any time, even when power is lost, ROM can retain data. However, once the data is written and can only be changed in a special way or at all, the ROM is often used as a storage system in an embedded system. The entire ROM generally has an OS partition (that is, a brush-brush partition) and a extended_rom partition (an OEM installation package that is automatically installed after it is restored to factory settings). There is also IPL (BIOS), SPL (load OS, display second screen boot screen.

Storage area (storage area and USB stick can read and write, no power to lose data).
4. What is the swap partition?
Swap partition, swap partition, the role of swap space can be simply described as: when the physical memory of the system is not enough, it is necessary to release a portion of the physical memory space for the current running program to use. The freed space may come from programs that have not been manipulated for a very long time, and the freed space is temporarily saved in the swap space until those programs run, swapping swap. In fact, swap adjustments are critical to the performance of Linux servers, especially Web servers. By adjusting swap, you can sometimes bypass system performance bottlenecks and save on system upgrade costs.
5. What is bootloader?
Bootloader is a small program that runs before the operating system kernel runs. With this applet, we can initialize the hardware device and establish a memory space map to bring the system's hardware and software environment to a suitable state in order to prepare the correct environment for the final call to the operating system kernel. In embedded systems, there is usually no firmware program like the BIOS (note that some embedded CPUs also embed a short startup program), so the entire system's load start-up task is entirely done by bootloader. For example, in an embedded system based on ARM7TDMI core, the system usually executes from address 0x00000000 when power-up or reset, while the system's Bootloader program is usually arranged at this address.

DRM technology works by first establishing a digital program Authorization center. Encoded compressed Digital program content, can be used to encrypt the key (key) protection (lock), encrypted digital program head holds the keyID and program Authorization Center URL. When the user is on-demand, according to the keyID and URL information of the program head, the program can be played by sending out the related key decryption (unlock) after the authorization of the Digital Program Authorization Center. Programs that need to be protected are encrypted, even if downloaded and saved by the user without the authorization of the Digital Program Authorization Center, which strictly protects the copyright of the program.
7. What is TrackID?
TrackID track recognition is a free music recognition service that, by recording a sample of an unknown song, and then sending it to a Web server via the Internet, after searching through the digital music library in Sony Ericsson, it will be able to feed back information-songs, singers and album names-to users within seconds. The source of a song sample can be a song that is played around the user or in a built-in FM radio on the phone. TrackID needs to be implemented through the network, the cost of using the TrackID service is the mobile data service fee charged by the carrier.
8. What is the purpose of unlocking the HTC, Sony Ericsson, and Huawei?
The Unlock program, launched by Sony Ericsson/htc/Huawei, is designed to popularize the bottom-up program, better integrate the Android system, and service Sony Ericsson/htc/Huawei Mobile users.
Unlocking tool released by Sony Ericsson/htc/Huawei developer Platform.
After unlocking the machine can open the installation platform, the installation of personal customized version of the system, the system to do high-level management.
9. What is root privilege?
Root privileges can be understood as a concept with our administrator permissions under Windows systems
。 Root is the Super Admin user account in Android, which has the highest system power and can do anything in the system. To prevent the software from changing the system text
, the Android system hides the root privilege, however, we usually modify some system files, or some software operation will use root permissions, our Android phone brush
When the system is installed, it is also necessary to have root privileges, to get and open root, we can do anything.
10, what is the brush machine?

11. What is recovery?
Recovery translation came to mean recovery, Unknown Incredibles, this is a recovery model on the phone. With this recovery, the user can implement the installation system (the so-called brush
Machine), empty the phone various data, for memory card partition, backup and restore and so on many functions. It is similar to ghost on the computer to restore, to the computer installed the system of friends may know that the computer has a problem,

Hard solution s off: After the hard solution of the mobile phone is also known as the White Card machine, the general mobile phone can be hard to solve, and after the hard solution to obtain the highest, hard solutions need equipment, can go to the mobile phone store;
Soft solution S OFF: Soft solution needs to take advantage of the software to obtain permissions, General F-mode brush into the unlock file (unlock file is hacker after the release of the Internet files), not all models are supported, access to the highest, but the brush will have a small chance to change back to the S on;
