By now, every one has in all likelihood heard of and may be intimate with Windows 7, Microsoft’s latest operating system. If you’re marveling if you ought to upgrade from XP (two operating systems ago) to Windows 7, the answer is a resounding ‘Yes’. Windows 7 offers so a lot of features and security improvements over XP that it’s a no-brainer to upgrade. Not to mention the fact that help for XP will end in the not-too-distant future. If you’re on the fence as to whether to upgrade from Vista to 7 I will give you three compelling reasons to do so. They are:
• Performance and security
• Compatibility
• Ease-of-Use and feature enhancements
When it comes to performance and security, Windows 7 is in a class by itself. When equated to Vista, Windows 7 boots closely twice as fast, thence causing less stress and higher productivity for those of you who turn off your PC on a regular basis. Additionally, Windows makes more effective use of video memory, resulting in major time savings for users. In XP and Vista all open apps used video memory disregarding of whether they were presently active or not. With Microsoft’s latest OS, only the active apps take up the system’s video memory. This makes for less screen freezes as you wait for the memory to catch up with you. Moreover, there is less ‘system bloat’, permitting for a more streamlined, and less cluttered, user experience. We now have the option of downloading all the extra bells and whistles Microsoft has to offer rather than having them installed by default for us.
Windows 7 is Redmond’s most secure operating system, taking the best features of XP and Vista and combining them, while dropping the ones that just didn’t make the grade. Of course, all the scheme exploits came across with XP and Vista have been taken care of in Windows 7. In addition, the latest OS offers improvements in encryption, with BitLocker (hard drive encryption) and DirectAccess (a built-in VPN client).
The latest OS has vastly bettered in the compatibility arena. Vista was your basic nightmare when it came to hardware compatibility. Many users experienced graphics card troubles when they upgraded to Vista. This is a thing of the past with Windows 7. Furthermore, the Compatibility feature, where the user may emulate a former Windows operating system to run older software, has primarily bettered over former versions.
Perhaps the best reason to upgrade to Windows 7 is it is usability and the features. Vista had a lot of quirks when it came to window layouts and performance. For example, when you were using Explorer, the left pane would move side-to-side in an try to help the user keep from calling for to scroll horizontally. It was fundamentally a moving target! This has been got rid of from Windows 7. Also, the window preview has been mainly bettered over Vista. Users may see any minimized window by merely hovering over it, in the taskbar, with the cursor. The biggest gripe most users seemed to have with Vista was it is implementation of User Account Control, or UAC. This is supposed to warn a person when he is with regards to to install something or access an OS feature that could potentially be harmful. Unfortunately, in Vista, each other mouse click seemed to invent the UAC warning box! This has been toned down rather a bit in version 7.
The number of security and user improvements in Windows 7 is far too long to list and go over here. But suffice it to say that if you are running a Microsoft version that is not version 7, you unquestionably need to consider an upgrade.

Simple: Read the book and pass the test
Now that there’s no longer a 20 wpm code requirement for Extra, there’s very little reason why closely any ham with galore good basic math attainments can’t upgrade, given a book this good. All it takes is reading the book and flipping to the questions to check your understanding of the material as you finish each section. I found it took me in regards to a week to do that and I passed with just one fault (which kills me because if I’d taken more time, I will have to have gotten that one, too!)
I found the book rather logical, well-written and very organized at explaining the material. I only spotted two minor errors: A garbled comprehensible statement of DeMorgan’s Theorem as “logic polarity” on page 7-5, and the schematics of three oscillators on page 7-42, each with two connections to Vcc but none to ground.
The whole point of the book is to aid you pass a multiple choice exam where all the questions are taken from a fixed pool and every one knows what they are. But the book nicely fends off the trap of merely helping you memorize the answers and focuses rather on explaining the conceptions so that when you read a test question, you’re competent of doing whatsoever calculations are required and you know why one specific answer is the best. The only places where I felt the author might have offered a little more discussion were in presenting the formulas for second and third-order intercept points on page 4-22 (it took me assorted hours to figure out where these came from!) and in the division on phased vertical antennas (page 9-20), where you’re given 15 charts to memorize but little comprehensible statement of how you might intuitively figure out what shape to suppose as an substitute to the rote memorization.
I commend this book. Go get your Extra!
It Helped me!
I haven’t taken a upgrade exam since 1984 so I was a bit intimidated with the probability of another FCC Exam. I researched the Web for info with regards to where to find the most finish study guides for the Extra exam. I in truth found the Question Pool on the Web, but I didn’t just want to “Memorize the Test” as galore have done in the past. I wanted the reasons for the answers and to refresh my now Older mind. The ARRL Study Guide was Very Thorough and yet to the point. The subdivisions were broken up nicely so you may study each division and take a break. The question pool is in the back of the book and the answers reference the page in the study guide where it is reasoning comes from. Perfect for me! It was an Excellent Review of a heap of material and a Great Teacher of the New material that I had to learn in order to upgrade to the most eminent class in novice radio. I Passed, Thanks to the ARRL Extra Class Study Guide.

I passed the firstborn time using this book
Some of the material in this book is in truth more difficult than the questions on the test I took, but I think that’s a good thing. The book goes through by each group and subgroup that is tested on the Element 4 Exam, explaining all potential items that could be covered on the test. It reads like a textbook, and it seemed to be free of errors and is very understandable allround the book. I read through the entire book once, then reread a heap of of the harder sections a few times. I used no other books or CDs, and took exercise tests online at web sites like qrz.com and eham.net until I got a consistent pass rate. Within three months of passing my Elements 1, 2 & 3, I took the Element 4 and passed with flying colors (missed only 4 questions out of 50).
