1. computing power is an abbreviation, which refers to the professional computer specially used for mining bitcoin. This kind of professional computer is called mining machine. The computing power of this kind of computer is called computing power. For example, the computing power of a mining machine is 14T, which is the computing power of this computer. The result of calculation is a special number code, which is bitcoin
there is also a model called cloud computing power, which is derived from the traditional use of mining machine to mine. It is in Sichuan, Xinjiang, Tibet and other places with abundant and cheap power resources, such as wind power generation and water conservancy power generation, that large-scale mines are built and maintained by professional personnel. If ordinary people participate in mining, they don't need to buy mining machines in person. They just need to buy the corresponding computing power to get bitcoin and Ethereum! This model is called cloud computing power!

2. There is no way to estimate the total computing power of computers all over the world, because everyone's computers, including CPUs, graphics cards and memory, are different. To calculate the total computing power of the world, I don't think anyone can do it.
3. At present, the tenth power computing platform can provide customers with idle computing power of personal devices worldwide and provide computing power support for world-class scientific research projects, involving mathematics, physics, chemistry, life sciences, astronomy and other fields. So far, the computing power can reach 30p, which is equivalent to the computing power of tianhe-2, the world's fifth largest supercomputer, and can meet the needs of all computing power projects on the market.

The world's first general-purpose computer "ENIAC" was born in the University of Pennsylvania on February 14, 1946. The inventors are American mokley and Eckert
the first computer was a giant, which used 18000 electron tubes, covered an area of 170 square meters, weighed 30 tons, consumed about 150 kW of power, and could perform 5000 operations per second, which was insignificant now, but it was unprecedented at that time. ENIAC is also known as electron tube computer, which is the first generation of computer. Electron tube computer because of the use of electron tube volume, power consumption, easy to heat, so the working time can not be too long
Extended data:ENIAC was born ring World War II. It was initially used as a tool to assist artillery to calculate the trajectory of artillery shells. It was manufactured one year before the Allied forces landed in Western Europe, but it was not completed until the cease-fire in 1945. In the early days of the cold war, the military discovered a large number of uses of ENIAC. Its 17468 vacuum tubes were used to test the feasibility of the early design of hydrogen bombs. The computer could execute 5000 instructions per second, which was 1000 times faster than an electric computer at that time

6. First of all, NVIDIA experience does not unify the computing power. It just sets the game to suit your graphics card. NVIDIA's shield uses the computer in the LAN to calculate, and it only uses the shield to play computer games. Android games or its own Tegra K1
Second, if you use this for online games, You have to consider your network bandwidth. In a short time, you don't expect China's broadband to transmit 1080p video smoothly, and there will be a lot of delay
moreover, if online game companies do this, imagine that the average computer for playing online games is about 4000 to 5000 yuan. How many computers do online game companies need to render pictures for each player? How much does it cost? Well, even if we remove some of the same rendering content of players, it will cost hundreds of millions or billions or more, as well as electricity bills and heat dissipation. Can you imagine how terrible this is?

7. In 1946, the first electronic computer appeared in the world. Today, it has been more than 30 years. In this short time, it has made great progress. The computing power of ordinary computers has reached 40 million times per second, faster than the speed of calculation and abacus
Why do computers work so fast
because the arithmetic unit and controller in the electronic computer are composed of bistable circuit and various "gate" circuits; In other words, they are calculated by using the high-speed transmission characteristics of electricity. We know that the transmission speed of electricity is 300000 kilometers per second, which is very fast. Therefore, the computing speed of the electronic computer is very fast< Secondly, the operation of electronic computer is very simple. No matter how complicated the problem is, as long as the personnel design the calculation program in advance and send the calculation program together with the original data to the computer, it can automatically calculate the original data step by step according to the manual program. Each operation is very simple. For example, to add, you only need to do 1 + 1 = 10, 1 + 0 = 1, 0 + 1 = 1, 0 + 0 = 0. There are only four cases (subtraction, multiplication and division are the same). Such a simple calculation, primary school students can quickly work out. Because the calculation is simple, the arithmetic unit can also be very simple; In other words, the bistable circuit and "gate" circuit are needed less, and the electronic path is also less, which makes the operation speed faster.

8. In the process of using XP, the running speed of the system will become slower and slower with the passage of time. Some friends may think of reloading the system, but after reloading, the common application software also needs to be re installed, which may be more troublesome. How to speed up XP without re installing the system
as long as you operate according to the following nine aspects, I believe your XP will run at a high speed again
first, speed up the startup and shutdown speed
in Windows XP, the system will send a message to the running program and remote server to tell them that the system needs to shut down, and wait for the response before the system starts to shut down. To speed up the startup speed, you can set the auto end task first
1. Find HKEY first_ CURRENT_ Set the key value of autoendtasks to 1 in UserControl panel desktop
2. Next, there is a "hungapptimeout" under the branch. Change its value to "4000 (or less), and the default value is 50000
3. Finally, find HKEY_ LOCAL_， Similarly, set waittokillservicetimeout to "4000"; Through this setting, the shutdown speed is much faster< Second, improve the speed of broadband
professional version of Windows XP retains 20% of the bandwidth by default, which actually has no effect on our indivial users. In particular, it is better to make full use of it
enter gpedit.msc in "start → run" to open the Group Policy Editor. Find "computer configuration → management template → network → QoS packet scheler", select "limit reserved bandwidth" on the right, select "properties" to open the limit reserved bandwidth Properties dialog box, select "enable", and change the original "20" to "0", thus releasing the reserved bandwidth< When using Windows XP network neighborhood, the system will search its own shared directory, printers that can be used as network share, scheled tasks and network related scheled tasks, and then display them. Obviously, the speed will be much slower. If these functions are of little use to us, we can delete them. Find HKEY in the registry editor_ LOCAL_ ， Delete the (printer) and {d6277990-4c6a-11cf8d87-00aa0060f5bf} (scheled task), restart the computer, visit the Internet neighbor again, you will find that it is much faster< Fourth, speed up the startup speed
to speed up the startup speed of Windows XP. You can achieve this goal by modifying the registry. In the registry editor, find HKEY_ LOCAL_ Managermemory managementprefetchparameters, find the enable prefetcher primary key on the right, and change its default value of 3 to 1. In this way, the scrolling time of the scroll bar will be reced< Some times, XP will prompt you to stop responding. It's very annoying. By modifying the registry, we can let it close by itself. In HKEY_ CURRENT_ Change the value of the character key value of autoendtasks to 1 in the user control panel desktop, and then log off or start again< In order to speed up the display speed of the menu, we can set it according to the following methods: we can set it in HKEY_ CURRENT_ Find the "menusholdelay" primary key under the user control panel desktop and change its value to "0" to speed up the menu display< 7. Clear the unused DLL files in the memory_ LOCAL_， Add an item alwaysunloaddll in Explorer. The default value is set to 1. Note: if the default value is set to 0, the function will be disabled< 8. Speed up the pre reading ability and improve the startup speed
Windows XP pre reading setting can improve the system speed and speed up the startup speed. The following modification can further make good use of CPU efficiency: HKEY_ LOCAL_ In the window on the right of prefetchparameters, change the numerical data of the enable prefetcher as follows: for example, if the PIII 800MHz CPU is used, it is recommended to change the numerical data to 4 or 5; otherwise, it is recommended to keep the numerical data as the default value, that is, 3< 9. Rece the number of items to be loaded ring startup. Many applications will be added to the system startup group at the time of installation, and the system will run automatically every time. This not only prolongs the startup time, but also consumes the system resources after startup
start the "system configuration utility". The "start" item lists the items and sources loaded when the system starts. Carefully check whether you need it to load automatically. Otherwise, clear the check box before the items. The fewer items loaded, the faster the startup. This item needs to be restarted to take effect< If you want to access the Internet easily and smoothly, do you notice that the available space of your computer system disk is decreasing day by day? Is it like the old monkey king that moves slowly day by day
Yes! In the process of windows installation and use, there will be a lot of junk files, including temporary files (such as *. TMP, *_ MP) log files (. Log), temporary help files (. GID), disk check files (. Chk), temporary backup files (such as *. Old, *. Bak) and other temporary files. Especially if the temporary Internet Files folder of IE is not cleaned up for a period of time, the cache files in it sometimes occupy hundreds of MB of disk space. These LJ files not only waste valuable disk space, but also make the system run slowly. I'm sure you can't stand this!

9. There is a real need to rent physical machines. National supercomputers are generally not rented out, which involves data security
10. First of all, it's easy to say that the boss scorched earth lion scorpion can also brush the energy board. This thing has been strengthened and become handsome. Ha ha, it needs 6 players and 6 Tyrannosaurus Rex. Each player should have a lucky suit and water. In fact, water is very important. Later, it will be said that doping is also needed to prevent mistakes. In the first picture, I quickly dismount the dragon, and then blow t to pull a Tyrannosaurus Rex to the side.
at this time, the camera is the character's perspective. I must give the boss a wave of purple sticky poison bullets, which will add a lot of vertigo. At this time, I will take stimulants. I don't know if too many stimulants will lose water like ginkgo, However, we should be able to do so at this time.
when we all ride the Tyrannosaurus Rex, we can walk and try not to go to the purple poisonous fog. Vertigo is added to Tyrannosaurus Rex. When the boss doesn't attack, it's the card owner, and then you have to pay attention to the sand bug, because it will repel the Tyrannosaurus Rex, so you keep inserting it into the boss. If you don't have the card owner, you have to repeat the above steps. When you see the stone man, it means that you are going to succeed. Don't worry about the stone man's biting. After playing the boss, you must dismount the dragon and pull the Tyrannosaurus Rex away from the corpse of the boss. There is a high probability that if you don't dismount the dragon, the Tyrannosaurus Rex will die.
the lion scorpion boss Tyrannosaurus rex has a 700 attack on 6, which is relatively simple.
next, a gorilla is very simple. Prepare a Tyrannosaurus Rex, a Velociraptor, or you are confident that you can reach the boss with high speed, Before going in, the overlord's head was pasted with 400c4. The characters put on their sweaters. It was really cold inside., The boss is responsible for leading the spider to the Tyrannosaurus Rex. The unlocked person rides on the Tyrannosaurus Rex, but the Tyrannosaurus Rex rider doesn't need the remote control. He thinks that you are likely to be lost by the boss in seconds, so he can ask another person to detonate it. It's better not to look at the picture when it explodes, because it's bloody to turn the camera (in fact, the memory will explode, and it's easy to drop the line), It's OK for this main team to cooperate well, and it's also important to consider the server delay, so that spiders can damage Tyrannosaurus Rex, and it's not too late to blow it up.
then let's talk about the next spider boss. It's very easy for the boss to get stuck. Tyrannosaurus Rex can go without adding blood. More than 10 people and more than 10 Tyrannosaurus Rex can kill it if they attack 800 or so, I'm playing PVE. If I find that it's a little bit worse than blood, if I can't get through it, I'll take the RPG tribe to fight against spiders in advance. I think the PVE mechanism won't hit things that are not with my own tribe, so I don't worry. Only one or two can get down, not too much, or the boss will be embarrassed if he doesn't have a card owner.
the difficult star above has been changed, and the amount of blood has increased. It needs 500 c4sorry
and there are still many left. After all, the fire dragon who is easy to roll over is the most difficult to fight, because spiders can pass as long as you have enough T-Rex attack, Gorilla as long as the normal server does not delay very stable, but the fire dragon is not the same, fireball seconds kill the rider, extremely difficult to card the owner's position. And it's a great test of the team's execution. You should obey the command.
fire breathing dragon, first of all, you can wear lucky clothes, about seven people can pass. Of course, you should cooperate with Tyrannosaurus Rex and whole blood. You think it's easy to have no card owner, and you need blood. When you land on the card next time, the magma of the boss field can step on, and there is not a lot of blood. After you go in, the dragon will quickly pull away, The first person who goes in can hold the hatred. Anyway, you can't stop running before landing. When a person is sprayed on the fireball, you can GG. When it hits the ground and gets stuck, the T-Rex's head up is to pull up the angle of view. Don't bite before it doesn't have to bite. If it can't fly off at the next take-off, it's OK. Don't move after the card owner, because you don't know who is the T-Rex card owner
