Using open wifi network?

[Zozo A]

im using an open wifi network that warns you "people can see what you send over the network" what exactly should i worry about?? i dont do online purchases or enter personal info (credit cards, social security) so i'm not worried about that
will they be able to see the websites ive been to (if i go to adult websites) and will they know its me?
what other things should i be worried about?
does using incognito mode on my browser make a difference with network security

It can tell what ip your computer is on the network and they can tell what u went to but finding u that would be harder

When you connect to a computer system via a wireless router (WiFi) your computer systems MAC address is stored.

Every device that has a network interface has a unique MAC (Media Access Control) address. This is usually expressed in hexadecimal such as 10:25:A4:59:EF:1C http://en.wikipedia.org/wiki/MAC_address MAC addresses are permanently assigned when the device is manufactured and can not be physically changed.

The wireless router then assigns your device a unique IP address via its DHCP service. http://en.wikipedia.org/wiki/Ip_address IP addresses are usually automatically assigned by the DHCP service running on your router, but can be set manually. They are in binary but usually expressed in readable format such as 192.168.1.1

Now you know the technical aspects of how your specific computer is identifiable, I will proceed.

Every time you go to a web page, your Internet browser requests that content from a remote server be delivered to your computer via HTTP.

All of the web content including the source code, formatting (CSS), graphics, flash content, etc. must be requested via your wireless router's connection to your ISP's router.

The Internet provider is required by law to keep a detailed log of the sites that you visit and files that you download. This router log file will be released to law enforcement with a proper subpena.

In addition the wireless router you are connected to keeps detailed logs, If the owner is tech savvy, they can easily see exactly where you have been and what you downloaded by examining their wireless router log.

Good Luck...

The things that you have to worry about are things like credit card info or any personal information like phone numbers, birth-dates, address's, passwords and on and on. Yes people could figure out what websites you are going to but also and a bigger problem is that you are giving people an easier way into your computer. Hackers are very good at putting little bits of information together. They will take a lil information from here and there ( things that you put out there for them but do not think are important ) and they will look for the other information they need on their own. There are things that you can do to make it a lil safer like a good anti-virus kept up to date and a firewall but the bottom line is that when you go on an open network you are taking more of a risk then usual.
