In the solid state drive parameters, there are also particles, solid-state hard disk particles have three types, respectively,

Currently, we recommend that you use four types of VDSL encoding: CAP and DMT.), DWMT, and SLC. DWMT (Discrete Wavelet Multitone) is a multi-carrier modulation system that uses a single-carrier Wavelet transform. SLC (Simple Line Code) is a baseband signal
8.NandFlash principle AnalysisThis section is mainly about Nandflash knowledge, first of all, the role, classification and access of Nandflash.
Role analysis: In the personal PC, use the hard disk to store the operating system, data and other information. In the field of embedded, it is called Nandflash with HDD function. So Nandflash is the storage of information.

So it seems, is not the smaller the better? Because a cluster is the smallest managed storage unit of a disk, if a file reads 4 units and 400 units, which one do you think is faster?
And the current large-capacity hard drive has not cared about those k, cluster this thing is not necessary too small.
Voice-over 1: The smaller the file, the more waste of storage space AH? So it is.
VoiceOver 2: Big also not suitable, small also not suitable, I do not understand. With Microsoft de

current folk self-made Rom basically requires that the SD card has three partitions to ensure that the Rom is successfully flushed and works properly.
The three partitions are:
(1) FAT32 primary partition: Common SD card space for file storage;(2) ext4 primary partition: used for app2sd. The Rom will automatically complete the installation of the application to the SD card instead of the mobile phone memory;(3) Swap primary partition: used to solve the problem of insufficient system memory.
During O M, an IP port is often used for telnet. If telnet is enabled, how can I exit?

I. Overview
In short, VDSL is a fast version of ADSL. With VDSL, the maximum downloading rate within a short distance can reach 55 Mbps, And the upload speed can reach 2.3 Mbps (19.2 Mbps or higher in the future ). Both the upload and download data channels can be frequently divided on existing POTS or ISDN services, making VDSL a good choice for high-speed and low-cost networks. Future upgrades may require switching to Echo Cancellation or other technologies to manage the line. Like ADSL, VDSL
