Hostapd

Okay, so you know how your house has a Wi-Fi name and a password, right? That's so you can connect your phone or tablet to the internet without using any wires. Well, sometimes people want to create a Wi-Fi network using their computer, like if they don't have a router or they're somewhere with no Wi-Fi. Hostapd is a program that lets you turn your computer into a Wi-Fi hotspot, just like your router at home. It helps you create a new Wi-Fi network and set a name and password for it. Then, other devices can connect to the network and use the internet. Just like that, you have your own little internet bubble!
