What is a hot spot? What does personal hotspot mean?

A hot spot is news or information that has attracted the attention or popularity of the masses, or refers to a place or issue that has attracted attention in a certain period. Such as:"Social hotspots", "Mianshan has become a hot spot for tourism".Wait.

Hot spot, or hot spot in English, has the following five meanings:

3.In places with dense Internet access through high-speed lines, users can access the Internet at high speed as long as they bring their laptops or PDAs that support wireless LAN to the area because the radio waves emitted in the area can reach a radius of tens of meters to 100 meters. In other words, manufacturers do not need to spend money on network cabling access, which saves a lot of costs.

That's why it's called a "hot spot".

4.Refers to the part of the gene that is particularly susceptible to mutations, either spontaneously or after mutagen treatment. Such a site was first discovered while studying spontaneous mutations in the R gene locus of T4 bacteriophages.

The presence of such sites in the gene means that there is a special arrangement of bases in the DNA, and the structure of the DNA in these places is very susceptible to changes in the structure of the DNA spontaneously or after mutagen treatment.

The part within the DNA molecule that is more susceptible to mutation compared to other parts of the same size. That is, loci in a gene (or protein) with a particularly high mutation rate.

5.In a tubular reactor that refers to an exothermic reaction, the temperature of the reaction mixture changes axially to form a temperature distribution, and the highest temperature is called a hot spot. At hot spots, the rate of heat supply is equal to the rate of heat removal.

The location and height of the hot spot can provide useful information about the operation of the reactor.

A lot of people pay attention to the news.

A hotspot is usually referred to as a WLAN hotspot.

The so-called mobile phone WLAN hotspot is to share the Internet with other WLAN-enabled devices. The handset can be used as a wireless router to broadcast the wireless network outward, which is then received by other WLAN-enabled devices, and the handheld device will use its own data connection to perform this function.

WLAN is simply a wireless LAN, with wireless LAN flexibility and mobility, simple point-to-point technology, infrastructure network provides distributed data connection and roaming, comparable to the function of a wired LAN, but without the limitation of cables.

Effective extension of the effective LAN, your mobile phone can be networked, use your mobile phone as a tool for surfing the Internet, and your mobile phone wifi is also a wireless access point, transmitting wireless signals, and other devices can access the Internet after entering the password.

Problems with personal hotspots.

1. The mobile phone consumes a lot of power and damages the battery.

After the mobile phone turns on the hotspot, it acts as a wireless router, which will inevitably cause more power loss and generate more heat during its work, due to the relatively poor heat dissipation performance of the mobile phone, if the mobile phone hotspot is used for a long time, it will inevitably bring damage to the mobile phone battery.

2. It will cause hardware wear and tear of mobile phones.

If the hardware performance of the mobile phone is not up to standard, after turning on the hotspot, many hardware can not enter the low power consumption, and the heat generated by the RF emission itself is not low, and the long-term charging will make the heat generation of the mobile phone heavier, which will bring great damage to the hardware of the mobile phone.

Regional hotspot issues refer to some controversies or contradictions, problems or crises that a region or country is currently facing. These issues or crises have attracted a lot of attention and discussion because they have sufficient political, economic, cultural and other resources and influence, and have become hot topics in society, which have a far-reaching impact on the development and stability of the region or country.

The types and scope of regional hotspot issues are very wide, some are political and military issues, such as territorial disputes, political disputes, wars and conflicts, and so on, some are economic and social issues, such as the gap between the rich and the poor, unemployment, social instability, and so on, and some are ecological, cultural, ethnic, and other issues.

Therefore, for regional hotspot issues, it is necessary to make a comprehensive and objective assessment, strengthen communication, coordination and cooperation among all aspects, and seek reasonable and effective solutions to promote the stability and development of relevant regions or countries.

The so-called regional hotspot issues are the issues that the locals are most concerned about at this stage, that is, the issues that are most likely to arouse the emotions of the people, and if they are not handled properly, they can easily cause riots.

Current social and livelihood hot issues.

1. Unfair social distribution still exists, and the gap between the rich and the poor has widened, becoming a hidden danger of instability.

2. The development of the east and the west is unbalanced, and the supply chain of food and clothing for some people in remote areas has not been completely solved, and the social assistance mechanism is not perfect enough.

Regional hotspots mainly refer to the problems in a certain area, which attract more attention and are easy to lead to conflicts.

Regional hot issues refer to the issues or events that a specific region is currently most concerned about and controversial, which may involve politics, economic friendship, society, culture and other fields, and have importance and influence. These issues usually arouse extensive discussion and concern, and have important impact and significance on local residents and social development.

The so-called regional hot spot is the issue that the locals are most concerned about in the current old rental section, and Napi is the issue that is most likely to arouse the emotions of the people, and if it is not handled properly, it is easy to cause riots.

The so-called regional hotspot problem is something that exists in this area that is hotter than Xingyan. For example, if there is something that has recently happened in the Huji Trouser Belt District that is quite sensational, then this kind of thing is called a regional hot issue.

Regional hotspot issues refer to issues that are of widespread concern to the people in the region and problems that urgently need to be resolved.

A hotspot is a technology that converts GPRS, 3G or 4G signals received by mobile phones into WiFi signals.

Portable devices such as mobile phones, tablets, or laptops can be connected to the Internet outdoors or in places without networks through wireless network cards or WLAN modules, so as to achieve network resource sharing. The mobile phone must have a wireless AP function to be used as a hotspot, and most smartphones come with a hotspot function.

Wireless access to WiFi hotspots has become a standard way for many devices to access the Internet. If you carry a portable device that supports Wi-Fi when you go out, such as PSP, iPadWiFi, etc., you have great restrictions on accessing the Internet at any time, and you must find a place that provides free Wi-Fi hotspot network, such as Starbucks, McDonald's, Village Base or a designated area of the hotel to access the Internet.

In fact, as long as you have a mobile phone with Android system, you can turn your mobile phone into a WiFi hotspot through GPRS network wireless Internet access, and then turn on the iPad, you can let the iPad go online at any time, which is very convenient.

Hotspot risk analysis

With the continuous development of Internet technology, the use of wireless networks, especially WiFi networks, is becoming more and more common. On the one hand, the WiFi hotspot, as an intermediate node, can obtain all the data of user interaction, so it is very important for user data security.

On the other hand, as the access point for users to access the network, the WiFi hotspot is the first barrier to control the access of malicious users to the network, and is an important basis for network access control.

However, due to many problems in the production and use of WiFi hotspots, the security situation of WiFi hotspots is not optimistic. As a kind of cheap network access device, WiFi hotspot has many manufacturers and uneven technical capabilities, and many devices have a large number of system vulnerabilities in the production design process, which provides the possibility for attackers to obtain device control permissions.

WiFi hotspot refers to converting the 4G signal network data on the mobile phone into a personal WiFi signal and then sending it out, so that other devices can use the data traffic.

How to set up a hotspot on your phone:

1. Take Huawei P20 mobile phone as an example, first open the "Settings" button in the phone.

2. Then in the settings page that opens, in the "Wireless & Network" option.

3. Enter the "Wireless & Network" interface and select the "Mobile Tethering" option.

4. After entering the new interface, click on the "Portable WLAN Hotspot" option.

5. After opening, you can turn on the switch button on the right side of the mobile phone name, and after opening, you can see a hot spot logo appear at the top of the mobile phone page.
