Q: I am thinking about buying an iPad. Will it connect to my existing wireless network? Do I need any special adapters?
A. The iPad is fully compatible with standard wireless networks. And it works with the latest wireless encryption. You should have no trouble connecting it to your network and getting online. You’ll also find versions of the iPad that connect to AT&T’s cellular network. However, I wouldn’t buy an iPad right now. The iPad 2 should be released this spring. Its new features will be worth the wait. The price of the original iPad may also drop when the iPad 2 is released. So you may get a better deal on that model.
Q: I heard that Facebook added encryption. How will it help me? And is it turned on automatically?
A. Facebook recently added the option to encrypt your sessions. Data sent between your computer and the site is scrambled. This makes it more difficult for hackers to intercept your data. However, it isn’t turned on by default. That’s because it can interfere with some Facebook functions and apps. To turn it on, go to your profile. Go to Account>>Account Settings. Scroll down until you see Account Security and click the Show link. There will be a Secure Browsing section. Click “Browse Facebook on a secure connection.” Then click Save.
Q: How do you uninstall programs on a Mac?
A. There are two types of Mac programs. The first type uses an installer similar to Windows programs. To uninstall these programs, use the uninstaller in the program folder. There are also self-contained programs. These don’t require an installation to work. To remove one from your machine, simply drag the program to the trash. Programs can usually be found in the Applications folder. Both program types can leave behind data. This clutters up your computer.
