I know. I know. You've heard it a jillion times. Every time an activist, prankster, or malicious attacker breaks into a high-profile system, the public is treated to a litany of (sometimes conflicting) advice about steps the victim could have taken that would have prevented it from happening. Most recently, a Montana television station hit the news after someone apparently guessed the password to the station's Emergency Alert System (EAS) device and managed to broadcast an alert that might remind horror movies buffs of a scene from the old George Romero film Night of the Living Dead. "Civil authorities in your area have reported that the bodies of the dead are rising from their graves and attacking the living," the prankster stated over the air.

If you are a writer or an editor, you have undoubtedly asked yourself at least once whether you need a style guide. After all, there are countless style guides available, including The Associated Press Stylebook and Briefing on Media Law (AP Stylebook), The Chicago Manual of Style (CMS), The Elements of Style (EoS), The Gregg Reference Manual (GRM), the Microsoft Manual of Style for Technical Publications (MMOS), and many more. I searched for "writing style guide reference manual" in Amazon's bookstore and, in a quick scan of the books, I found over 40 different style guides; that was only a fraction of the 400 English results. You get the idea – there are tons of options. So someone thinks style guides are a good idea. But why?

President’s Day finds me loading up my son to bring him into the office with me because my husband and I clearly failed to be on the same page in regards to daycare for this school holiday. Nothing a quiet corner in my office with a laptop, iPod touch, and a cup of hot cocoa can’t handle. We’ve got this!

So you are reviewing some practice test questions as you prepare for a Cisco exam and you come across a scenario that states something like, “…and all the routers in the topology are manufactured by Cisco.” You immediately shift your focus and begin to examine the available choices, scanning for anything that has to do with the Enhanced Interior Gateway Routing Protocol (EIGRP). We’ve all done that, right?

A proofreader provides an essential service — one you might not realize is necessary until you spot an error or inconsistency after your work is published. Here is a list of some of the benefits of having a proofreader review your work:
1. A good proofreader looks for spelling and grammar issues your word processing program likely won't catch.

Early on in your journey into the world of networking, you probably learned about a Local Area Network, or LAN. A LAN is a collection of devices, all typically located in close proximity, with connectivity from one device to another. Figure 1 shows a LAN for an organization with several departments.
You asked, we answered! When you asked about creating your own topologies in NetSim, we listened and have now released labs to help you do just that. The two new Demo labs we released allow you to work through the steps to create a topology and then configure it. You can do so much more in this lab than simply evaluate NetSim – you can create, configure, modify, and examine everything within your simulated network. You can see the steps in the Demo labs performed in the videos below.
2.6 Upgrading to Windows 7
By Val Bakh
Although replacing an older operating system with a newer version is commonly referred to as an upgrade, the exact, technical definition of the term upgrade is more specific. When you are performing a clean installation (that is, when you choose the option to perform a custom installation) on a volume that contains an older operating system, the existing operating system and all installed software and personal data are either completely removed or disabled and a new operating system is installed instead. All applications have to be reinstalled, and personal data can be restored from a backup. If you choose the option to perform an upgrade, the new operating system gracefully replaces the existing operating system while preserving the installed applications and personal data. Not all upgrade paths are supported. For example, an x86 (32-bit) edition of any Windows operating system cannot be upgraded to an x64 (64-bit) edition and vice versa. To perform an upgrade, you always need to initiate it from within the existing installation. For example, to upgrade Windows Vista to Windows 7, you need to boot the computer into Windows Vista, insert a Windows 7 DVD, and click Install now. This means you can never perform a true upgrade if you boot the computer from a Windows 7 DVD into Windows Preinstallation Environment (WinPE).
