the biggest selling point of ant S3 miner compared with Avalon 3 miner is low power consumption. Although low power consumption is an advantage, the price is relatively higher
Avalon III chip and roasted cat III chip both adopt 28nm process technology, which is also used by domestic mainstream miner.
Ant miner is the first cryptocurrency miner brand in the world with a market share of about 70%. The mining machine is developed by bitmainland and has a patent in mainland China. At the beginning, ant miner had only bitcoin miner. Later, its business expanded to other cryptocurrencies, such as Ethereum, dascoin, Leyte, Monroe, etc
ant mining machine adopts ASIC chip designed by bitcontinental, which is proced by TSMC. All chips are made of BM prefix. Each miner has three to four circuit boards, and there are dozens of chips on the circuit board. Therefore, each miner can only be used to mine one or more cryptocurrencies using the same algorithm
ant mining machine needs special mining software, and can not use third-party software. In addition, because of its high power, the ant miner also needs to be used with a special fire ox
The ant miner is often criticized as monopolizing the cryptocurrency mining instry e to its 70% market share, which goes against the purpose of cryptocurrency decentralization. Because Monroe was worried that the mining machinery would monopolize the mining market, Monroe announced to change the mining algorithm a few days after the launch of Monroe (X3 model) despite the opposition of Monroe community, so that all mining machinery could not be used to mine Monroe. Bitcontinent also encountered the failure of its first proct herethe ant miner will use a lot of electricity and proce a lot of waste heat in the process of operation. This leads to a large amount of electricity being consumed for mining or cooling, causing a lot of social criticism. Too much ant mining machine at the same time also led to fire and power failure, causing social inconvenience
there are hundreds of commonly used subnet masks
here we only introce the two most commonly used subnet masks, which are "255.255.255.0" and "255.255.0.0"
1. Network with subnet mask of "255.255.255.0": the last number can vary from 0 to 255, so 256 IP addresses can be provided. However, the number of available IP addresses is 256-2, that is 254, because the host number cannot be all "0" or all "1"
2. Network with subnet mask of "255.255.0.0": the last two numbers can be changed arbitrarily from 0 to 255, and 2552 IP addresses can be provided. However, the number of available IP addresses is 2552-2, that is 65023
the subnet mask setting of IP address is not arbitrary. If the subnet mask is set too large, that is to say, the scope of the subnet is expanded. According to the subnet routing rules, the data sent to the destination machine that is not in the same subnet as the local machine will be considered to be in the same subnet because of the wrong judgment. Then, the data packet will cycle in the local subnet until it times out and is discarded, so that the data cannot reach the destination machine correctly, Causes the network transmission error; If the subnet mask is set too small, the communication between machines that belong to the same subnet will be regarded as cross subnet transmission, and the data packets will be handed over to the default gateway for processing, which will increase the burden of the default gateway and rece the network efficiency. Therefore, the subnet mask should be set according to the size of the network
if the scale of a network does not exceed 254 computers, it is OK to use "255.255.255.0" as the subnet mask. Now most LANs will not exceed this number, so "255.255.255.0" is the most commonly used IP address subnet mask; The largest primary and secondary school campus network that the author has seen has more than 1500 computers, and the LAN of this scale can use "255.255.0.0"
default subnet mask
in Windows 2000 server, if an IP address is specified for a network card, the system will automatically fill in a default subnet mask. This is a subnet mask automatically generated by Windows 2000 server to save user input time. For example, the IP address "192.168. X.x", which is most commonly used in LAN, has a default subnet mask of "255.255.255.0". In general, the IP address can use the default subnet mask.
