ieee 802 1 q standard

The use of wireless networks has become commonplace. Are you clear about the standards under the IEEE 802 protocol? Now let's make a summary here. First, let's take a look at the basic meaning of this Protocol. The most common standard for wireless LAN is the IEEE-defined industrial

data LAN.IEEE 802.10-Security for interoperable LANs.IEEE 802.11-Wireless LAN.IEEE 802.12-Priority high-speed local area network (100MB/S).IEEE 802.13-Cable TV (CABLE-TV).IEEE802.4 is the token bus access method and the physical layer protocol. examples of token bus topologies are "ARCNET"In the process of studying the 802 standard, the industrial community (gen

,bond, and you will not be able to configure VLANs successfully. For the understanding of the VLAN concept, there are a few points to emphasize: 1.VLAN separate the broadcast domain; 2. A single VLAN simulates a regular switched Ethernet, so the VLAN splits a physical switch into one or more logical switches; 3. Communication between different VLANs requires three levels of participation; 4. When multiple switches cascade, the VLAN is identifie

The following content is not necessary to satisfy the needs of curious students.IEEE 754 is currently supported by the C standard, and many hardware are supported. It can be said that currently floating point processing is basically the world of IEEE 754.Http://zh.wikipedia.org/wiki/IEEE_754 Chinese Material1.4 IEEE floating point calculation

IEEE 802.11ac is a brand new WLAN (WLAN) standard being integrated into wireless devices. Currently, products supporting this standard are available in the market, and various manufacturers have begun to enter the mass production stage. Production and testing engineers must be able to support new 802.11ac test specifications and be compatible with existing WLAN s

If the GCC limits. h is used, the value of each macro depends on the built-in definition of the GCC compiler, which is generally the same as the value here.(2) uchar_max must be equal to 2 ** CHAR_BIT-1, and the signed integer generally has min =-MAX-1.(3) The feature. h file defines some macros that indicate compilation options, such as t
