. Finally, with a hybrid design pc, you can still have a full version of the system as it is now. 　2. Solve screen resolution scaling problem In 2014, PCs with 2K-resolution screens had become mainstream, while manufacturers such as Dell and Asus had launched 4K displays, and Lenovo and Toshiba were also planning to launch 4K-resolution laptops. Although the precision of the

of 20k, its basic storage unit is a cluster, with two files, a 7k, a 1k. When the cluster size is 4k, the disk is divided into 5 clusters, two files Occupy 3 clusters, that is, the use of 12k, which wasted space is 4k, that is, the creation of internal fragments 4k. So we know that internal fragmentation is primarily a waste of disk space. Note that the fragment

Du = = Disk usage (disk usage, disk space occupied) ls = = = Apparent sizes (file length, file length field defined in the Files data structure) The amount of disk space a file occupies and the size of a file is a different situation. The footprint depends on the size of the file system block, Linux generally defaults to 4k (4096), so a file size of 1 bytes, the smallest to occupy 4k, if you create a filesy

Block is used to hold the actual data, the common block size is 4K, its boot partition is 1 k, the other normal partition is 4K.? The inode does not contain a file name because the file name does not belong to the prope
