What is a 408 error and what does 408 mean?

Cause. A 408 request timeout error is an HTTP state, which means that your request is taking longer to send to that server (i.e., the request to load a web page) than that server is ready to wait. In other words, your connection timed out.

Solution. 1. Refresh the page, or re-enter the address in the address bar and press enter, because many times this error is only temporary, and another attempt is often successful.

However, please note that if you open a payment page or an order submission page, this may cause you to make duplicate payments, and while most programs should be developed with this in mind, we should be more careful as users.

2. Try to visit other sites, such as Google or Baidu. If these sites are accessed normally, it means that the problem is not yours, but the fault.

3. If the access to Google or Baidu is slow as mentioned above, the problem may be your network. Test your internet speed to determine your current internet speed or check with your service provider.

4. Try again later. If the HTTP 408 error is a high volume of traffic, it may be due to an increase in traffic that is causing a problem with the server. This will disappear with the departure of some users, so it should be okay to try again later.

5. If the above operations are useless, you can try to contact the administrator and tell him that an HTTP 408 error has occurred on the site. The admin will definitely thank you

The web page is slow and times out. It could be a software conflict, or it could be a poor network connection.

Server error, fine.

408 is a subject for postgraduate entrance examination**. Just like the subject ** of Math I is 301. The contents of Computer 408 include:

Data structuresPrinciples of Computer Composition, operating the system of trousers and computer network.

1. The structure of the test paper.

From 2009 to 2020, the structure of the computer unified examination paper has not changed, and there are two major question types in the test paper: multiple-choice questions and comprehensive application questions, of which 40 multiple-choice questions account for 80 points, and 7 comprehensive application questions account for 70 points.

The computer unified examination involves the knowledge of data structure, computer composition principle, operating system, and computer network, and the score of the test paper has not changed, with 45 points for data structure, 45 points for computer composition principle, 35 points for operating beam systems, and 25 points for computer networks. Therefore, in terms of the structure of the test paper, there should be no change in the 2021 computer unified examination paper.

2. Examination syllabus.

The syllabus of the unified computer examination is the same as the syllabus of the public course examination, and the time announced by the Ministry of Education is uniform, and the national master's degree students in that year are stipulated.

Authoritative policy guidance books for postgraduate examinations such as the examination scope, examination requirements, examination form, and test paper structure of the corresponding subjects of the entrance examination.

From the analysis of 2009-2020, the examination scope of the corresponding subjects in the computer unified examination syllabus is relatively extensive, and the syllabus has not changed in the past ten years, and the 408 test paper cannot cover all the test points at all, which basically leads to the fact that the questions of the 408 test are rarely repeated every year. Therefore, in terms of the exam syllabus, there should be no change in the syllabus of the 2021 computer unified examination.

3. Subject analysis.

Although there is no change in the structure of the UEC papers, there is still a change in the distribution of scores in the multiple-choice questions and comprehensive application questions of each subject. These changes also have a certain impact on the difficulty of the exam, so I will analyze the changes in each subject for students according to the subject.

Hello dear. A 408 is usually one of the HTTP status codes and indicates that the request has timed out. HTTP status codes are response status identifiers returned by the web server to the client, and each status code has its own specific meaning.

In the muffled message, a 408 status code indicates that the request sent by the client timed out while the server was waiting, and the server terminated the request. Typically, this is an error caused by a client that does not receive a response from the server for a long time after sending the request, or because the amount of request data sent is too large and the server takes too long to process. If a 408 error occurs repeatedly, you may need to check the network connection quality, server performance, request data volume, and other issues to determine the root cause of the problem.

If my answer is helpful to you, please give a thumbs up (comment in the lower left corner), look forward to your like, your efforts are very important to me, and your support is also the motivation for my progress. Finally, I wish you good health and a good mood!

408+319=827

It can be directly equaled, not approximately equaled.

Answer: Approximately equal to 800

Solution: 408 + 379 = 797, according to the rule of five into the four-legging code family, a number is accurate to the hundred digits to see the number on the ten, ten digits are the source of digging 9 is greater than the late crack disadvantage 4, to carry the position, then this number is about equal to 800
