What is the allocation number?

Question 1: Is there any form tool that can automatically assign numbers to people? Try Form Master. You have this function, which will generate a unique self-increasing ID for each piece of data. This ID can be changed through reminders. Sent to form fillers and form administrators. You can try

Question 2: What does the ip number mean? Port number---the identification number of application software with network functions. Note that the port number is not fixed, that is, it can be assigned manually by the user (of course, it is usually defined when the software is written). Of course, there are many application software with recognized default ports, such as FTP: 20 and 21, HTTP: 80, TELNET: 23, etc., so I won’t list them all here. A software can have multiple port numbers, which proves that the software has more than one network function.

0-1023 is a recognized port number, that is, it has been recognized or reserved for software that will be recognized, while 1024-65535 is a port number that is not publicly defined. Users can define these by themselves. The role of the port.

So what exactly does the port number do? Please continue reading below.

When a computer starts a program that can be accessed remotely by other computers, it must open at least one port number to allow outside access. We can think of a computer that does not have a port number open as a sealed room. Of course, a sealed room cannot accept access from the outside world, so when the system opens a program that allows outside access, it naturally needs to open a window in the room. To accept access from the outside world, this window is the port.

So why do we need to give port numbers to distinguish them? Since a program opens a port, can't all external information be accessed through this opened port? The answer is no. Why? Because the data uses the port number to notify the transport layer protocol to which software is sent for processing, the data has no intelligence. If many programs use one port to receive data, then when a data packet from the outside comes, The transport layer doesn't know which software to send it to for processing, which will inevitably lead to confusion.

Last time it was mentioned that the Layer 4 header of a data segment encapsulated by the OSI Layer 4 transport layer contains two port numbers, namely the source port number and the destination port number. The destination port number The function has been introduced above, let us understand the original port number.

The source port number is generally a number from 1024-65535 dynamically generated by the system itself. When a computer A accesses computer B through the network, if it needs the other party to return data, it will also be randomly generated. Create a port greater than 1023, tell B which port to send the data to when returning data, and then the software starts listening to this port and waits for the data to be returned. After B receives the data, it will read the source port number and destination port number of the data packet, and then record them. When the software creates the data to be returned, it will use the original port number in the original data packet as the destination port number, and replace it with the destination port number. Its own port number is used as the original port number, that is to say, the original and destination in the received data packet are reversed, and then sent back to A, and A repeats this process until the data transmission is completed. A releases the source port when all the data is transmitted, so the same software does not necessarily use the same source port number every time it transmits data.

Question 3: What is a social security number? A social security number is a number assigned to you by the social security system. It is unique like your ID card number and is your identity in the Social Security Bureau. The social security number will be recorded for you throughout your life, including your payment, illness, unemployment, participation in employment training, housing payment, etc. Everything will be recorded for you.

The computer number on your social security card is your social security number.

Question 4: High School Mathematics.

Group assignment problem in permutation and combination: What is the difference between numbered groups and unnumbered groups? Number grouping is equivalent to number rearrangement

Question 5: What does unallocated numbers mean? In fact, number allocation refers to the division of mobile phone numbers by region or mobile phone network. For example, the first 7 digits of the mobile phone can be used to check the number ownership. This is the region. For another example, 133 represents China Unicom and 138 represents China Mobile, which is the mobile phone network. As for your friend not receiving your text message, it may be because his mobile phone has not activated the text message service (the SMS center number is wrong), or it may be a temporary problem with the network, or maybe the number is really irregular.

Question 6: What does the new stock allocation number 0 mean? The average market value of the 20 trading days before T-2 on the day of subscription. The average market value in Shanghai is more than 10,000 yuan, and you are eligible to subscribe. Every 10,000 yuan can be subscribed. 1,000 shares; those in Shenzhen are eligible for more than 5,000, and can subscribe for 500 shares for every 5,000 yuan. It should be noted that market value refers to the market value of the stocks held, not the available funds in the securities account.

Question 7: What is the traditional number allocation in football? No. 1: Optimus, the last line of defense of the team alone. As the saying goes, "One man can block the barrier, but ten thousand men cannot open it." This is the patent of goalkeepers. They continue to write the magic of "willing to mend the sky with one hand". No. 2: This is a number worn by full-backs and may not be so noticeable on the pitch. No. 3: Speaking of No. 3, the author can't help but think of loyalty, because Paolo Maldini is the best No. 3 in the world. The No. 3 in the red and black sword-striped shirt makes this number extraordinary; he himself is not only Milan is also a symbol of a period in Italian football. Carlos is in the club and Lucio also wears No. 3 in the Brazilian team. They are also the best defenders in the world. In this World Cup, Fabio Grosso came out wearing the No. 3 jersey in Italy's match against Australia. He performed well in the semi-finals against Germany and the final against France. In the final penalty shootout, his penalty secured Italy's fourth World Cup. He won the championship in his first World Cup. In this sense, Grosso not only did not eclipse No. 3, but also surpassed his predecessors. No. 4: This can only remind people of Beckenbauer. The football emperor wore the No. 4 jersey of the German team and ushered in a new era of free men. No. 4 was recorded in history along with Beckenbauer. In addition, there are only a few No. 4s such as Hierro, Vieira, Zanetti, and Gerrard that can be remembered. No. 5: This is usually the number used to mark the central defender. No. 6: Baresi has been wearing the No. 6 jersey in AC Milan for more than ten years, leading the trend of an era. Future generations all worship Milan's No. 6 jersey. , Redondo took over the mantle of his predecessor. Although his personal charm was worthy of this number, he did not bring new glory to it. Desailly, Makelele, Costinha, John Terry, Argentina's Heinze, and Brazil's Roberto Carlos also added a lot to No. 6. No. 7: The first number separated from the back line, often worn by the full midfielder and the second forward. The former is represented by Beckham and Figo, and the latter is Bebeto and Lopez. When playing as a winger, this number seems to be lacking in energy. He is good at skills and sneak attacks, and is an alternative to the frontcourt. Of course, there are many stars who are favored and even worshiped in this position. In addition to the above-mentioned players, there are also Raul, Shevchenko, Caniggia, Deschamps, Bastian Schweinsteiger, and Argentina’s Savio. Ola, Del Piero of the Italian team, Adriano of the Brazilian team, Malouda of the French team and so on. Cantona wearing No. 7 and becoming a leader seems to be a special case. No. 8: This is a role that does tiring work in the midfield, the best number for defensive midfielders. Wearing the No. 8 jersey, Dunga helped Brazil win a World Cup championship and a runner-up. Dunga became famous far and wide. Gattuso of AC Milan and Italy, Hamann and Frings of Germany, and Butt of England are also typical figures of the No. 8 engineer. Of course there are exceptions. England's Lampard is an attacking midfielder or full midfielder, Brazil's Kaká is an attacking midfielder, Spain's Xavi, Portugal's Petit, and Czech's Boboski are also attacking midfielders. Bulgaria's No. 8 Stoichkov is an out-and-out shooter.

No. 9: The real center! I believe this is the number that every kicker dreams of. It symbolizes the core of the team's offense and the killer who cuts through the heart with a sword. It has been worn by great forwards such as Van Basten, Papin, Careca, Batistuta, Shearer, Ronaldo, Crespo, Kluivert, Rooney, Toni, Torres, Van Nistel Rui, Jan Kohler and others often play the role of terminator. They are all true No. 9. After the scenes of attacking the city, what we see the most is the unchanged No. 9. However, the Italian team often does not follow common sense and often gives the number 9 to defenders. Tassotti in 1994 is an example. No. 10: I don’t need to explain the meaning of this number. I don’t know exactly when it started that No. 10 became a leader on the court. Pele, Maradona, Platini, Matth?us, Zidane, Ronaldinho, Bergkamp, ??Totti, Owen, Rosicky... too many, these all-powerful players The characters are almost a complete history of football. Number 10 is a kind of ability; Number 10 is a kind of status. If you are No. 10, you may be the No. 1 player on the team. No. 11: Without Romario, this number would lose 80% of its value. This should be the number of the small forward. Rummenigge, George Best, and Giggs all became famous by wearing No. 11. But the one who best embodies the style of No. 11 is none other than Romario. The "Lone Wolf"'s elusive scoring, superb shooting and isolated and unruly style of play are all...gt;gt;

Question 8: What are the rules for allocating trademark application numbers to window zero? Answer for you: There are no publishing rules for this. They are numbers assigned by the National Trademark Office after internal acceptance. This is unique, one number for each trademark, just like an ID number

Question 9: How to tell What number is assigned when I subscribe for new shares? Check in the account on the third day after subscription.

Question 10: What is the relationship between social security number and social security code? At the beginning, when social security was first implemented, each insured person was assigned a unique number to distinguish him from other insured persons. It is a social security code, an internal business code

Later, people realized that they could use the ID number as a unique identifier to mark insured persons, so the social security codes of many new insured persons became identities. ID card number, but the original insured person’s code also exists and can coexist.

Later, the Social Security Law proposed that the state establish a nationally unified personal social security number. An individual's social security number is a citizen's identity number.

Therefore, social security numbers and social security codes, one is required by the state, and the other is an internal business system. The two have nothing to do with each other, but the content may be consistent.

In many new business systems, these two codes are unified, and there will be no difference in the future.
