Simple information about how the network came about

www is not necessary, generally www means web page, the same domain name can be preceded by different applications such as www, mail, etc., so now many ** do not have www

HTTP is required, if you don't enter it, the browser will automatically add the HTTP prefix to you by default, indicating that you use the HTTP protocol to access resources, and others such as FTP protocol (the browser must enter FTP to access FTP resources, because the browser uses HTTP by default).

http is a hypertext agreement, and the successful access by directly entering the domain name or URL address is because the browser intelligently supplements "http:". In addition, the domain name does not have www, and can be bound to the fixed IP of the server, and the domain name can be resolved to the fixed IP of the server through the domain name server.

HTTP is a WAN protocol added by default to the Internet, and the LAN does not add wwwIt is a PC domain name resolution.

m.It is a mobile domain name resolution.

If you do a domain name point, it will automatically identify whether you are a PC or a mobile terminal, and you will jump by directly entering the domain name.

This. Try it and you won't know.,No matter which one you lose.,The browser will automatically complete it.,http: is the protocol.,It doesn't matter if you lose or not.,The browser will automatically select the appropriate protocol.,But now it's more popular https:

Encrypted transmission protocol, more secure and efficient. And whether you lose or or, this is in line with the naming rules of **, and as long as your**full name is determined, it will eventually point to the only one that is determined**, this is the fool fault tolerance mechanism of the browser now, just like shouting a person's name, you are the only one in the class called Wang Zijian, no matter how you call Wang Zijian, Zijian, you know that you are calling yourself.

It doesn't matter, one meaning, it's just omitted.

There are no pros and cons to the network itself, only how you use the network will have pros and cons.

I didn't expect you to add more.

The Internet is an inevitability for our society!

He made it very convenient for us!

But I remember a great man (like Marx) who said that there are two sides to everything, there is a good side and a bad side, because this is a virtual society, and compared to the real society, it is quite difficult to regulate! It's almost impossible, so cybercrime is quite rampant!

This requires us to raise our own awareness of prevention! Don't look at it, don't watch it! Don't listen, don't listen, don't listen, don't!

It is still far from enough to do this, because this is a technological crime, and the criminal methods are in step with the times, so our awareness of prevention must also be in step with the times! Pay more attention to this aspect of things, the benefits are great!!

Clause. Second, I would like to share some of my own views on teenagers' access to the Internet!

I watched the anime "Naruto" and gave me some inspiration!

Just like the protagonist in the anime, teenagers are very eager for the "approval" of others, they want to be the focus, they want to be recognized by others, make a lot of friends, and be better than others!

However, the generation that grew up in the honey pot is too weak! Too lazy!

They don't want to face reality, they don't want to work hard, they are afraid of failure!

The Internet became their best tool!

In online games, they can get a lot of power without much effort!!

Get the approval of others (latecomers who are lower than them) and you can make a lot of friends! What they pay is "just time and money".

Even if you fail, you can find a new game and start over.

If they are recognized by others in real life, they will be different, and they will not have Internet addiction!

Therefore, if I want to quit the Internet addiction of teenagers, I should be guided by our educational methods!

Almost all primary and secondary schools do not pay attention to ideological and moral courses, I think this is the biggest mistake, the current generation of children, the heart is very fragile, can not withstand the blow, and some children, the outlook on life and values are fundamentally distorted!! Whose fault is it that they don't know how to behave, they don't know how to fit into this society?

The school said that it was the fault of the family, and the school was responsible for imparting knowledge and did not have much energy to teach them how to behave, and the family said that it was the fault of the school, and the children did not spend as much time at school as they did! I said that there is not a good thing on either side, as the saying goes, a slap in the face does not make a sound! The problem is not caused unilaterally, I don't know if the school and the family have ever thought about it, if a child has problems with psychology, moral standards, values, and worldview, is it useful for you to teach him so much knowledge?

It is true that when he enters society, he can live better than others, but will they be happy? (Sorry, off topic!) ）

It seems that the word count is almost reaching the limit, and there are still many unspoken)

What about the emergence and development of the Internet, the click of a mouse to communicate zero global, zero distance, and the speed of light! Let the rural people also keep up with the development of information. Any business or individual can be grafted onto the Internet.

There is a quick and convenient way out of information and outlets. In the future, if you don't know the Internet, you will be illiterate. With the development of the Internet, the era of mass entrepreneurship is also coming.

If the broadband is not available, please first confirm whether the broadband is suspended due to arrears, and if so, please recharge first.

If the mobile broadband fails due to non-arrears, we recommend that you perform the following operations:

Restart the modem and plug the fiber connector back in before surfing the Internet.

Determine the status of the modem indicator, for example, whether the WAN indicator is solid or flashing when the port is connected to the modem normally;

Remove the router, create a broadband connection, and reconfigure the router;

If the above methods still do not solve the problem, you can call the local 10086 to report the broadband fault.

It's not simple, first of all, determine whether the physical link is normal, that is, whether the network cable is connected well, whether the route is disconnected, etc. Then check whether the network connection is normal, this step is usually judged by ping the gateway, if it can be pinged, then then check whether the DNS resolution is normal, usually with nslookup. If there is no problem with the DNS, it means that there is a problem with the protocol layer, find out whether there is an ARP attack on the LAN.

Usually, after a hacker invades a host, he wants to gain control of the local area network, then he will launch an ARP attack, which means that your organization's network has fallen, and the OK network failure has escalated into a security war. It's not easy, it's definitely not easy.
