What is the hotspot?

🔹 What is a Hotspot?  A hotspot is a specific location where people can access the internet wirelessly using Wi-Fi technology. Hotspots are usually created by a wireless router connected to an internet service provider. They are commonly found in public places like cafés, restaurants, airports, hotels, and libraries.  Hotspots allow users to connect their smartphones, laptops, or tablets to the internet without using mobile data. Some hotspots are free, while others require a password or payment.  There are two main types of hotspots:  1. Public Hotspot → Open for everyone (e.g., coffee shop Wi-Fi).   2. Personal Hotspot → Created by a smartphone or device to share its internet with others.    1. #Hotspot   2. #WiFi   3. #InternetAccess   4. #WirelessNetwork   5. #PublicWiFi   6. #PersonalHotspot   7. #MobileHotspot   8. #FreeWiFi   9. #Connectivity   10. #WirelessInternet

00:00What is a hotspot? So that is the topic of this video. Now a hotspot is an actual location where

00:07people can go to access the internet wirelessly with their mobile device, such as a laptop,

00:13tablet, or a smartphone. And a hotspot could be either public or private. A public hotspot

00:20location will be things like a coffee shop. Now coffee shops are very common in having a hotspot

00:27so that their customers can have internet access using their wireless device. And other common

00:33public hotspots would be things like hotels, airports, and even on airplanes, or maybe even on a starship.

00:44But anyway, hotspots are created with a Wi-Fi router or a wireless access point that's connected to an

00:51internet service provider. And these routers and access points will broadcast a Wi-Fi signal so

00:57that people nearby can connect and access the internet. And you would connect to these hotspots

01:03just like you would with any other Wi-Fi network. You would select the network ID or SSID and type

01:10in the password if it has one. Now some public hotspots are open with no password and some are

01:17secured with a password. So if the hotspot requires a password, you need to find out what it is. And also,

01:25not all public hotspots are free. There are some that you have to pay for. So these were examples of

01:32public hotspots. Now an example of a private hotspot would be something like your home. Now most people

01:38who have an internet connection in their home would have a Wi-Fi router that would broadcast a wireless signal

01:45so that anyone inside their home, such as family and friends, would be able to access the internet.

01:51And another example of a private hotspot would be tethering, which is created by your smartphone.

01:58Now a lot of times there might be a situation where you're away from your home and you need your laptop

02:04or your tablet to be able to access the internet. And if you're not near a public hotspot, then you can use

02:11the convenience of your smartphone to create a hotspot. Smartphones get their internet access

02:17by using cellular networks. And you can transform your smartphone into a wireless access point

02:24so it can share its internet connection with your other devices. Now most smartphones would have the

02:30option of creating a hotspot at the touch of a button. And once the hotspot is turned on,

02:36your phone will broadcast a Wi-Fi signal just like a Wi-Fi router or an access point so that nearby devices

02:44can connect to its signal and access the internet from the smartphone's cellular network. And another

02:51method of connecting to the internet is by using a mobile hotspot. A mobile hotspot is a portable device

02:59that uses cellular networks to connect wireless devices to the internet. So if there are wireless devices

03:06within 30 feet of a mobile hotspot, they can join it and have internet access. Now mobile hotspots come

03:13in two different forms. They will either be a freestanding device like you see here or as I discussed

03:19previously, they can also come as a feature built into your smartphone. And mobile hotspots are available

03:26through cell phone carriers such as Verizon, AT&T, T-Mobile and Sprint. So now going back to public hotspots,

03:35now there are some security concerns when you're dealing with public hotspots, because they are in

03:40fact public, which means that just about anyone can connect to them. And so you're going to be sharing

03:46that connection with other people, which could include hackers. So if you're going to connect to a

03:52public hotspot, you should take certain precautions. So for example, if you have any folders that are shared,

03:59you should turn off folder sharing or at least password protect your shared folders. Another

04:05good thing to do is to install an antivirus program. And if you have a firewall, make sure the firewall is

04:12turned on. And it's also a good idea to install a VPN on your device. A VPN will prevent hackers from

04:19stealing your data because it encrypts the data that's being transferred from your device and the internet.

04:25So any activity that you do when you're connected to a public hotspot, such as visiting web pages

04:32or transferring files, the data is encrypted and kept private when using a VPN. So guys, just remember

04:40that a hotspot is an actual physical location. A hotspot is not hardware. A hotspot is not a router

04:47or an access point, or your mobile phone, or even a mobile hotspot, or even a coffee pot that catches on

04:55fire for no apparent reason. A hotspot is a location where you can go with your wireless device to access

05:01the internet. And also if you're interested in getting a VPN, I'll put a link in the description below of

05:08this video with a special discount. So thank you everyone for watching. Please subscribe and also
