What does bitcoin a card n card mean

1. Dig with n card, you can't even collect the electricity fee... If you want to mine, you'd better use a card honestly

2. Hello, the mining of bitcoin is actually doing distributed computing, and the strongest point of graphics card is floating-point computing. A card and N card are more suitable for floating-point operation than a card. N card should spend more energy on rendering, and a card has more Alu units than n card. At this point, a card is 2-3 times faster, so mining speed with a card is faster

3. Before the appearance of mining machine in 2012, the era of mining with graphics card used a card, because mining is to split hash operation into multiple sub operations. At that time, a card can complete one operation with one instruction set, while n card needs three instruction sets to complete one operation. Therefore, the actual operation efficiency of a card is more than twice that of N card, which is close to three times

in fact, n card has greatly enhanced the mining efficiency in the Maxwell architecture, not inferior to a card. But the Maxwell architecture came out too late. When the earliest Maxwell architecture graphics card, such as gtx750ti / 750, came into the market (early 2014), the mainstream currencies could not dig out anything with graphics cards (all mining machines). Therefore, few people use n-card mining.

4. It's Sha. This is the security mechanism of bitcoin. All transaction records should be packed and divided into blocks, and Sha hash should be calculated. Only blocks with a specific hash value can be recognized by the network. Each block contains the hash value of the previous block to form a block chain. If there are more than one branch chain at a time, only the longest chain is recognized. The counterfeiting of small computing power cannot catch up with the long chain. You can't fake Transactions unless you have 51% of the computing power. Therefore, the more scattered the computing power is, the higher the total computing power of the whole network is, and the more secure the network is.

5. The mine card is the a card in the special configuration for bitcoin mining a while ago. Because bitcoin mining requires 24-hour continuous work all the year round, even if the parameters of such cards look very high-end, their actual life is basically hollowed out, and most of them are scrapped in less than a year or two.

6. A card, nicknamed mine card, is specially used for mining

8.

A computer can't access the Internet at the same time by inserting two network cables. The reasons are as follows:

1. a computer generally has only one network cable interface, so it can't insert two network cables at the same time

2. the IP address of a computer can only be one, and two IP addresses cannot exist at the same time

3. If two network cables are inserted into a computer, IP and DNS will conflict with each other. In this way, there will be no fixed IP or DSN, and it will not be able to access the Internet normally< br />

9. 1. Problems: (1) there are more lean ores and less rich ores; (2) there are more associated ores (Jinchang, Panhua and Baiyunebo) 3) Indiscriminate mining, damage to the environment, serious waste. 2. Countermeasures: strengthen the legal system; Comprehensive utilization should be carried out to improve the utilization efficiency of mineral resources; Research and development of new varieties and substitutes
