Why 802.11ac will kill the 5 GHz Wi-Fi band

different push for 802.11ac. they see the primary beneficiary of 802.11acSingle antenna (1 stream) mobile products. By using 11ac's 80 MHz bandwidth mode, link rates of single-antenna mobile devices can be almostTripled(150 to 433 Mbps )! This will enable faster peer-to-peer wi-fi direct data transfer and higher quality screen-casting/throwing from phones and tablets to large flatscreens via wi-fi display. but again, the higher speeds will come at the expense of using wider swaths of BandwidthI

Init is one of the most indispensable programs in Linux system operation. Init process, which is a user-level process initiated by the kernel. The kernel will find it in several places in the past that used Init, and its correct location (for Linux systems) is/sbin/init. If the kernel cannot find Init, it will try to run/bin/sh, and if it fails, the boot of the system will fail.Linux 7 RunLevel (0: shutdown, shutdown mode,1: single-user mode,2: Multi-

When B data is written to the third Disk in a certain band, and B data is checked in the fourth disk, in this way, both data a and data B can be read and written at the same time. VII. Raid 6 Raid 6 adds a verification area on the basis of RAID 5, each of which has two verification areas. They use an unused verification algorithm to improve data reliability.
