Q. What is SSL that I'm always reading about in articles about online security? Thanks for being there, Mr. M. My husband thanks you, too, since I used to pester him with my questions.

A. You're very welcome. Mr. Modem is pleased to have saved many marriages by alleviating technological strife. (At least that's my story and I'm sticking to it.) SSL (pronounced as separate letters, S-S-L, never as “sissle”), is short for Secure Sockets Layer, a protocol originally developed by Netscape for transmitting private information securely via the Internet. It's more complicated than that, but does anybody really want to read a snooze-inducing dissertation about SSL and TSL symmetric cryptography? I think not.

The bottom line is that most mainstream browsers today support SSL. Financial transaction pages of Web sites (including use the protocol to securely transmit confidential user information, such as credit card numbers. For your own safety, never enter financial data into a Web-based form if the URL does not display the prefix https. The “s” is important because it confirms that the Web page being accessed resides on a secure server.

Q. How can I find out what processor my computer has? I called tech support for a problem and they asked me. I had no idea what to tell them.

A. If you ever need to know what processor you have or how much RAM (memory) your system has, in Windows XP go to your Control Panel and double click the System icon. You will find this information on the General tab, in the Computer section. In Windows Vista, click Start > System Information.

In Windows 7, click Start and in the search field, type System, then click the System search result. As an alternative, go to your Control Panel > System and Security > System.

Q. I'm still getting used to my iPad and so far, so good, but is there a faster way to scroll through screens? For example, if I'm at the bottom of a Web site and I want to read a story back at the top, I know I can repeatedly drag my finger over the screen and move to the top. It just seems there should be an easier way. Do you know of anything?

A. All that finger dragging is an excellent way to develop dreaded phalangeal fatique that afflicts many amateur iPadders. Here's how the pros do it: Tap the Title bar of any Web page once. WOOOOSSHHH! You will be transported immediately to the top of the page. Note: Making the "wooosh" sound is optional. It doesn't speed up the process, but it does create a dramatic effect that is guaranteed to impress your friends and family.
