(1) What is the ETH interface

ETH interface refers to the interface, which is the most widely used local area network communication method and also a protocol. The Ethernet interface is the port for the network data connection.
Each version of Ethernet has a limit on the maximum length of the cable (that is, the length without amplification), the signal within this range can propagate normally, and the signal beyond this range will not be able to propagate.
To allow building of larger networks, repeaters can be used to connect multiple cables together. A repeater is a physical layer device that receives, amplifies and retransmits signals in both directions.

Several common types of Ethernet interfaces.
1. SC optical fiber interface
SC optical fiber interface has been applied in the era of 100Base-TX Ethernet, so it was called 100Base-FX at that time (F is the abbreviation of optical fiber word), but at that time due to the performance It is not more prominent than twisted pair, but the cost is higher, so it has not been popularized. Now the industry is vigorously promoting the gigabit network, and the SC fiber interface has received renewed attention.
2. RJ-45 interface
This interface is the most common network equipment interface we are now, commonly known as “crystal head”, the professional term is RJ-45 connector, which belongs to the type of twisted pair Ethernet interface . The RJ-45 plug can only be inserted in a fixed direction, and there is a plastic shrapnel that is stuck with the RJ-45 slot to prevent it from falling off.
3. FDDI interface
FDDI is the one with the highest transmission rate among the mature LAN technologies at present. It has the characteristics of timing token protocol, supports a variety of topological structures, and the transmission medium is optical fiber. Fiber Distributed Data Interface (FDDI) is a set of protocols developed by the American National Standards Organization (ANSI) for sending digital signals over fiber optic cables.

What does ETH mean

ETH is the Federal Institute of Technology in Zurich, located in Zurich, Switzerland. The world-renowned world’s top research university has ranked first among universities in continental Europe for many consecutive years, and enjoys the reputation of “the first university in continental Europe”. It ranks sixth in the world in the 2020 QS World University Comprehensive Rankings.

ETH Zurich was founded by the Swiss Confederation in 1854 and started teaching in 1855 as a technical specialist school. Originally it consisted of six faculties of architecture, civil engineering, mechanical engineering, chemistry and forestry, as well as an institution integrating mathematics, natural sciences, literature, social sciences and politics.

ETH Zurich ranks 9th in the world in the 2016 QS World University Rankings; 8th in the world in the 2017 QS World University Rankings; 2018 QS World University Rankings in the world 10th in the world; 7th in the world in the 2019 QS World University Rankings; 6th in the world in the 2020 QS World University Rankings.

ETH Development Status

The Swiss Federal Institute of Technology is the Swiss Federal Institute of Technology for the purpose of The needs of the country’s industrialization, established in 1855, this is a federally affiliated university. It conducts scientific research not only for its own development, but also for the whole country, Europe and the world. The university started with only industrial and civil construction, forest science, mechanical engineering and chemistry, and later added humanities, social and political science.

The school currently has 26,000 teachers and students from more than 100 countries distributed in 16 departments, with teaching and research fields covering architecture, engineering, mathematics, natural sciences, social sciences and management sciences . For ETH, the number of enrollments and tuition fees are not considered at all. With federal support, the college receives 9.2 billion Swiss francs of educational funding each year, not including property management and new teaching facilities.

The Academy also receives up to 3 billion Swiss francs in funding from third-party funding and its own technology transfer. These funds are all used for running schools and scientific research, or directly (mostly) used on more than 20,000 students and 500 professors (more than 9,000 full-time equivalent staff-years).

Even so, ETH continues to say that it lacks money in its annual reports for the past two years, and the reason is very simple. In order to compete with other institutions (universities), our independence is paramount, so we need a long-term sustainable financial support.

We expanded our student enrollment by 4% last year, and now our student body is 156% of what it was ten years ago, the number of professors has increased by 23%, and the number of researchers has increased by 53%, while government research funding has only increased 42%, the available area for education has only increased by 7%, and we are facing huge challenges.

But it is not surprising at all in Switzerland. Due to Switzerland’s unique educational system, the country concentrates all its resources in 10 universities and 2 federal institutes of technology. In other words, the higher education level is There are 12 schools, and the country is not short of money, so the current situation is formed.

(iii) The three currencies BTC, ETH and USDT on Bit Blue Whale are��What does it mean

BTC is bitcoin, ETH is ethereum currency, and USDT is a token issued by the American Tether company for the equivalent value of the US dollar

(iv) What is ETH-Ethereum

Ethereum (English Ethereum) is an open source public blockchain platform with smart contract functions. Ether) provides a decentralized virtual machine (“Ethereum Virtual Machine”) to process peer-to-peer contracts. The concept of Ethereum was first inspired by Bitcoin in 2013-2014 by programmer Vitalik Buterin and is now 2.0. Ethereum 2.0 is also something that the entire currency circle is eagerly waiting for. In order to celebrate the birth of the genesis block of eth2.0 on December 1st, ZB officially supported the exchange of ETH2.0 verification nodes at 17:00 on November 20, 2020 Hong Kong time, and invested its own ETH for verification node mining And exchange QETH to obtain liquidity, and participate in mining after redemption, and now give back to user benefits, the first 1000 ETH can enjoy the over-exchange of QETH at a ratio of 1:1.02. Compared with ETH2.0, QETH has many advantages: guaranteed liquidity, users do not need to bear technical costs, the participation threshold does not require 32 ETHs as low as 0.1ETH, the nodes are maintained by the platform, and the benefits are distributed according to ETH2.0.

(v) What is the relationship between EOS, ETC and ETH?

After the hard fork of ETC ETH is generated, and the relationship between these three currencies is like the relationship between the yen, the Korean won, and the U.S. dollar.

㈦ Mining ETH, how to get the balance to the account

This is necessary, as installing a good graphics card without drivers will greatly reduce the performance of the graphics card. Due to the use of components with higher technical parameters, the graphics cards with excessive overclocking have good overclocking capabilities, so many players advocate overclocking graphics cards to improve performance. However, there are both advantages and disadvantages. Overclocking will also lead to a large increase in the heat of the chip. When it reaches a certain level, the problem of blurred screen and crash will occur. Even if this is not the case, it will also appear unstable in some applications such as games. phenomenon, so overclocking must be moderate. 4
