FET
Open Category:Electronics
Fet: FETA new generation of amplification elements developed based on the principle of the transistor has three polarity, the gate, the drain pole, and the source pole. It features a high internal resistance of the gate, silicon dioxide is a voltage-controlled device that can reach hundreds of megabytes of Euro.---------------------------------------------------------
The method for determining whether a FET is good or bad is totally different from that of a transistor. The following describes how to determine whether a FET is good or bad: 1. the multimeter is equipped with a diode; 2. the red pen is connected to d pole, and the black pen is connected to S pole. In turn, the quantity is connected to a pressure drop of V; 3. the red pen is connected to the G pole, and the

file descriptor restrictions At least on Ubuntu, the maximum number of file descriptors for each common user is 4096 by default. So, if you want to test more than 4000 concurrent connections, you need to increase this value. The simplest way is to add a line similar to "* hard nofile 16384" in/etc/security/limits. conf before testing, and then run the ulimit-N 16384 shell command.
