In the past, a Net cafe would offer computers on the premises for you to use to access the net. Now, many locations provide wireless access, so that you would bring your own computer or other device with wireless capability and use in the area where the wireless network is provided (the hotspot).
By the 21st century, some Net cafes or locations may still provide computers to customers, but these are gradually disappearing with the ubiquity of wireless devices and hotspots. Today, when you are looking to use public-access Internet, you'll likely be looking for WiFi hotspots.
You might find hotspots at cafes, hotels, restaurants, bars, airports, on a bus or other public transit, and other areas such as at public parks or public libraries.
In using public WiFi, I suggest avoiding logging into Web sites for your sensitive financial or personal information. If you access your email, make sure that you use the https protocol (Install HTTPS Everywhere on your Web browser). Essentially, I don't login to any password-protected site while using my computer on a public WiFi network such as in a Net Cafe--I use a set of Surf Links (see about) for browsing Web sites on public WiFi networks.
If you get free wireless or computer access, be sure to be a good customer (buy food or drink) and follow use conditions.
In using a Net cafe computer, you can set yourself up with Web-based email and other services. With Web-based email and file storage, you can send and receive messages and access your data from any Internet-connected computer in the world.
