A: MAC Address Table detailedWhen it comes to the MAC address table, you have to say how the switch works because the switch forwards the data frame based on the MAC address table. There is a table in the switch that records the corresponding relationship between the MAC address of the LAN host and the switch interface

When a user encounters an online video on a Mac or browses to some Web site, it always shows that Flash is out of date and needs to download a new version, but you don't see any updates on the Adobe website. Originally for security concerns, Apple has shielded all versions of Adobe Flash player plug-ins remotely from the Mac OS x system. Including the newly released 16.0.0.235, as well as older versions of

Note: Relationship between the IP address and the MAC address: the IP address is specified according to the current IPv4 standard and is easy to remember without hardware restrictions. The length is 4 bytes. The MAC address is the physical address of the network card. It is stored in the EPROM of the network card, which is related to hardware and hard to remember. The length is 6 bytes.In TCP/IP networks, c

In Windows, by modifying the Hosts file, you can block certain websites, debug the server, or crack down on some software. The Apple Mac system also owns the hosts file, but the Hosts file path is different. Many people want to modify the hosts file but are not aware of the location of the hosts file under the Mac.First, you need to understand what is the hosts file?The Hosts file is a computer file that is used to store information about each node in
