Buying a New Computer

What to Look For in a New Computer



The good news is that computer prices have dropped a lot over the past few years, and the computing power you get for your money is going up! I don't recommend used computers for people, because the rate of change of computer technology will render most systems obsolete within three years. If you're a computer novice, wondering what kind of computer, monitor, hard drive, memory, and operating system to get... here's some advice to get you rolling.



Windows or Mac?

You may have friends, relatives or neighbors trying to pull you into the "Windows vs. Mac" wars. In my opinion, the choice of operating system really doesn't make much difference. From a beginner's perspective, each has point & click interfaces that are pretty easy to use. Both will take you to the same Internet, and enable you to send and receive email. Both offer word processing, and the documents they create are interchangeable. Because Windows-based computers make up 90% of the market, they are cheaper. It's the law of supply and demand in operation. And in some areas, it may be hard to find technical or repair support for Apple Macintosh computers. So if you're budget-minded, and you don't have any friends willing to help you with Mac issues, I suggest you go with a Windows-based PC.

A good entry-level computer with monitor can be purchased for under $400, and sometimes you even get a printer thrown in. So what should a novice look for in terms of speed, monitor, memory and hard drive specs? It doesn't have to be all that confusing...



What about Horsepower?

The CPU (central processing unit, or "processor" for short) is the brain of your computer. In general, the faster the better. Processor speeds are measured in gigahertz (GHz) and as of this writing, the fastest models available operate at about 4 GHz. Entry-level machines start at about 1.5 GHz and are more than adequate for web surfing, email and word processing. If you see a computer with a processor that has a speed specified in megahertz (MHz), steer clear -- these are older models.



The Memory

The next decision you have to make is how much RAM memory you need. Don't confuse RAM with hard drive (file storage) space. RAM is the temporary working memory that your computer uses to perform calculations and manipulate files. When you open a document, it is copied from the hard drive into RAM. As you and your word processor work on the file, the modified copy exists only in RAM. When you save the file, it is copied from RAM back to the hard drive, or permanent storage. And as with CPU power, the more RAM you have, the better your computer will perform. I recommend you have a minimum 512 megabytes (MB) of RAM, but with 1 gigabyte (1024 MB) you'll notice better performance.





The Hard Drive

The hard drive is your permanent file storage. All of your personal files, such as word processor documents, photos, music, and emails are stored here, in addition to software packages and the operating system. Most new PC's come with a hard drive that's 40 gigabytes (GB) or larger. I recommend you start with a hard drive of 80 GB, but consider doubling that if you plan to keep lots of photos, music or videos on your computer.



Go For a Large Monitor

Here's the formula: Larger Monitor = Less Eyestrain and Less Scrolling. I recommend a 17-inch monitor, or even a 19-inch if you don't mind spending a bit more. Don't worry about brand names here, they're all much the same. Stay away from 14 or 15-inch monitors, they're just too small to be practical.



What About Software?

Most of the software you need will come pre-installed on your new PC. Windows comes with Internet Explorer (for web browsing) and Outlook Express (for email). Many PC systems include a word processor, such as Microsoft Word, WordPerfect, or OpenOffice. If your computer doesn't come with any of these, I suggest you purchase Microsoft Works, which will give you MS Word, a spreadsheet similar to MS Excel, and other useful programs.



Look for a computer that comes with anti-virus software pre-installed. If yours doesn't come with any anti-virus package, check with your Internet service provider to see if they offer anything for free. Failing that, you can download the free AVG package.
