We’ve all heard that more bars mean better service, that a camera needs a lot of megapixels to take good pictures, and that Macs don’t get viruses.
There seem to be as many technology myths as there are people who repeat them. How can you separate fiction from fact?
Let’s explore how much truth there is to these widely shared technology beliefs.
So whether you buy a $50 HDMI Monster cable, which has an average three-star Amazon.com rating from 140 reviews, or you purchase this $7.99 cable from Mediabridge, which has a five-star rating with 5,451 reviews, your TV will look the same.
When your phone has full bars, it actually means you have a good connection to a nearby tower. But if thousands of people are accessing the same tower, or your provider’s backend network isn’t great, you’ll still get dropped calls, fuzzy reception and slow data times.
Where this myth gets harmful: Solid-state hard drives don’t need to be defragmented. If you do defrag, you might damage the data cells and shorten the drive’s lifespan.
As Gizmodo explains in this article, megapixels aren’t everything. A good camera needs a high-quality lens and a large light sensor to take great photos. So an expensive camera with a ton of megapixels might produce photos of lesser quality than a cheaper camera with fewer megapixels and a better lens.
Now, we’re not saying that’s a good reason to skip Macs altogether — and indeed, they do get fewer viruses than PCs — but if you were planning on buying one because they’re virus-free, think again.
If you own a Mac, use Avast Free Antivirus for Mac, which has a 4.5 rating at CNET.
Extended warranties are sometimes pricey and may offer little or no extra protection.
Batteries can overcharge, but only if they are charged at a higher-than-specified voltage. You shouldn’t hook any appliance up to a voltage higher than needed, and batteries are no different.
