Chapter 396 Computer (3)

After efforts from all sides, the performance of Germany's first-generation computers is now close to that of the second-generation transistor computers in the original time and space; the advanced assembly language that appeared in advance has made the computer's logical computing ability more powerful, greatly improved its reliability, and increased its computing speed to more than 100,000 times per second.

After watching the demonstration of this computer, Yannick nodded with satisfaction and ordered. "Send one to the intelligence department, and from now on the enemy's password will be transparent to us."

Since the day it was born, the password has been strictly protected by the user. In order to ensure the security of the password, people racked their brains and made every effort. At the same time, because the password contains many important military secrets, the password is the best intelligence for spies, and even takes a lot of effort.

According to historical records, the password was first created in Greece. After entering the 16th century, it became a system for countries around the world to establish permanent envoys to each other. Diplomats often passed on various intelligence they obtained. Because there has been great development between the password and the password channel, the simplest one is the password identification of correspondence. In war, the password is also widely used. In the history of war, there are countless examples of failures in operations due to not paying attention to the use of codes or codes being cracked by the enemy.

Late at night on August 17, 1914 during the First World War, a clear beeping sound suddenly rang out in the earphones of the German radio operator stationed in the Marienburg area. After translation, it was found that this was a plaintext telegram sent by the Russian army, which contained the action plan of the Russian Army Shamonsolov Army Group and the battle intention of mutual coordination with another army group. At first, the German army did not dare to believe that such an important military secret would be sent in plaintext, but after careful reconnaissance and verification, it was proved that the intelligence was true.

This unexpected gift was soon delivered to the German commander Hindenburg. He was overjoyed and immediately mobilized 160,000 troops to quickly surround the Shamonsolov Army Group and launched the famous Battle of Tannenberg. After four days of fierce fighting, 100,000 Russian troops were wiped out, and the Russian commander Shamonlov committed suicide.

In World War II, although the Japanese army seized the initiative in the early stage of the war by stealing Pearl Harbor, they suffered heavy losses in the middle and late stages of the war due to the repeated decryption of the communication codes by the US military. The most typical example is the death of General Isoroku Yamamoto, commander-in-chief of the Japanese Combined Fleet. In the spring of 1943, the situation in the Pacific War was becoming increasingly unfavorable for the Japanese army. In order to launch an offensive, Isoroku Yamamoto decided to go to the Solomon Island in the South Pacific for inspection. At 17:55 on April 13, the commander of the Japanese 8th Fleet sent a coded telegram to the commanders of the inspected units about Yamamoto's inspection schedule (including arrival and departure time) in 5 days, so that each unit could prepare for the reception. Unexpectedly, the American codebreakers intercepted this important information, and as a result, Isoroku Yamamoto was shot down by the US military on the way to the inspection and buried in the sea.

In war, if the code is decrypted or stolen, it is equivalent to handing your life to the enemy. Therefore, there has always been such a warning in the military: keeping secrets is to protect lives, and keeping secrets is to protect victory.

Now that Germany has this epoch-making computer, Yannick feels that the chances of success have increased a bit.

"Send one to Dr. Tesla." Yannick still doesn't know whether Nikola Tesla's gravity engine can be successfully developed; but when he visited him not long ago, he found that Tesla was still in good health, not like someone who would die three years later (January 7, 1943).

As far as Yannick knows, Tesla died of heart failure, but Tesla's personal doctor said that he was in good health and had no heart problems. The fate of many people in this time and space is different from before, and Tesla may live a long life.

"Send one to Dr. Oberth's space exploration department." The last time the V-2 rocket reached an altitude of 189 kilometers during a flight test, it was also the first human item to reach the height of space. According to the current scientific research progress, satellites will be launched into space in the near future.

"Send one to the nuclear energy research and development department." The design and manufacture of the atomic egg is a series of physical and chemical problems, and it also involves many aspects such as nuclear material filling, radiation range, explosion power, ignition timing, test explosion window, monitoring range, data calculation, etc. These calculations are often closely linked, and any link that is wrong or inaccurate must be recalculated.

"One will be kept for further improvement."

"One..." Just as he opened his mouth, Yannick found that the five computers had been divided up, and he couldn't help but pat his forehead. "Not enough, far from enough. Dr. Neumann, how much does one computer cost?"

Dr. Neumann said respectfully. "About 4 million Reichsmarks."

Yannick took a breath. The cost of the first vacuum tube computer in the original time and space was about 500,000 US dollars. Today's 4 million Reichsmarks is about 1.2 million US dollars. Five machines cost 20 million Reichsmarks, which can build more than 200 German main fighter planes BF109F.

However, according to the performance ratio, these 4 million Reichsmarks are very, very cost-effective. If the advanced computers of the future can be built now, Yannick will not hesitate to invest even if it costs 40 billion.

After hesitating for a while, Yannick gritted his teeth. "Build five more!" After giving instructions, he mentioned another thing. "How's the stuff I gave you last time?"

In 1956 in the original time and space, transistors gradually replaced vacuum tubes, and the second generation of computers was born. Just two years later, Kilby, an engineer in Texas, invented the integrated circuit (IC), combining three electronic components on a small silicon chip.

In 1964, the third generation of integrated circuit computers was officially launched. Small and medium-scale integrated circuits (with less than one thousand logic gates integrated on each chip) are used to form the main functional components of the computer; the main memory uses semiconductor memory. The computing speed can reach hundreds of thousands to millions of basic operations per second.

Last time, Yannick took the time to sort out the concept and specific principles of integrated circuits and sent them over.

Dr. Neumann said with admiration. "Your Highness, your foresight is really unmatched. We have studied it carefully and your theory is completely feasible. It's just that such a precise circuit board cannot be made with the current technology. I estimate that it will take at least three or four years to complete it."

"That means we won't see it before the end of the war." Although there are some regrets, Yannick didn't feel too much loss. After all, they are already a big step ahead, and it is harder than climbing to the sky for the opponent to catch up.

After some more encouragement, Yannick left Area 51 and returned to the palace, where he saw Reinhard waiting in the office. "Your Highness, we have found the person you are looking for."
