Win10 brings the voice assistant, Notification center, Edge browser and many security improvements, still people because the interface is not gorgeous, privacy protection has a potential threat, experience easy to lag, blue screen and many other issues and choose not to upgrade. If you have upgraded WIN10, users who play hardware typically have to consider a problem at this point: what are the WIN10 operating system requirements for configuration? What is the difference between the basic configu
maximum size of the FAT32 support partition in Windows2000 is 32GB. ü File System : NTFS is a recoverable file system. Users rarely need to run disk hotfixes on NTFS partitions. NTFS guarantees partition consistency by using standard transaction log and recovery techniques. NTFS uses log files and checkpoint information to automatically recover file system consistency when a system failure event occurs. ü folder compression : NTFS supports compression of partitions, folders, and files.

The main hardware specifications, the charm Blue U10 equipped with 1.5GHz of MediaTek MT6750 eight core processor, running 2GB/3GB memory. We know that basically the Phantom of the following mobile phones are using MediaTek eight-core chip.
So for this is only equipped with relatively mainstream chips and 2/3GB memory, its performance will not be so strong, for ordinary users, the basic enough, but playing a large online game estimated to bring a bit difficult.
The first is from Ra
The iTOP-6818 Development Board is a four-core arm eight-core Development Board fully compatible with the iTOP-4418 Development Board, CPU frequency 1.4GHz, Memory 1GB DDR3 (2GB optional), storage 16GB EMMC, onboard Gigabit Ethernet, Gps,wifi Bluetooth, gyroscope and other modules, 3G modules and 4G modules are also supported. Applicable to smart home, medical, media, automotive, handheld devices, communications and other industries.4418 Development B

third layer can specify 256 numbers, so the total size is as above;
Total: Direct, indirect, double indirect, three indirect plus total, get + + + 256*256 + 256*256*256 (K) = 16GB
At this point we know that when the file system to the block format 1K size, can accommodate the largest file is 16GB, compare the file system limit table results can be found to be consistent! However, this method can n

Summarize the file related operations, you can draw the following three features:1. File operation only need to provide a file name to the function, so the program itself only needs to maintain the file name;2. No need to create file object and input, output stream, provide file name can return file obj
, output stream, provide file name can return file object or input output stream3. The file object is returned for the path operation.2. External storage:The most confusing is the external storage, if the PC is also to distinguish between external storage and internal storage, then the drive is internal storage, U disk or mobile hard disk is external storage, so we can easily take this understanding to look at the Android phone, think that the intrinsic storage of the fuselage is internal storag
