As with any area, the IT world has its share of misinformation, misconception and information that is simply dated. Today we will take a look at several of these ideas that have crossed my desk since the last time we published a Gnopes article:
Myth: The more pixels you have, the better the picture will be.
Truth: While this is a common belief, the lens, circuitry and sensors- to say nothing of the photographer’s mastery of composition and lighting- are much larger factors. High megapixel count is the ability to blow up the image without digitizing.
Myth: Internet…World Wide Web… same, same.
Truth: The Internet is a network of networks spread throughout the world. The computers, cables, routers, switches and other devices as well as the software that runs them form an infrastructure that allows information to be shared.
The World Wide Web, on the other hand, is simply one of those networks. By entering a string of characters called a uniform resource locator (URL) into a browser. The URL is an address that points to the page you are looking for.
So, when you type http://www.gnosysnetworks.com/gainesville-tech-blog/ to get to this post, you “surfed The Web” using the internet as a surf board.
Interestingly enough, your browser actually reads the address you type into the browser backwards…but more on that in another post.
Myth: If you don’t drain and recharge your phone and laptop batteries, they will decrease in their capacity to hold power.
Truth: Once upon a time, in the days of Ni-Cd (Nickel Cadmium) batteries it was true. Batteries would, over time “remember” the short charging and the life of the battery might decrease. Most devices are now powered by lithium-ion batteries that do not suffer from this flaw. The life of the battery will still eventually decrease but not due to short-charging.
Myth: Magnets will erase your data.
Truth: It’s partially true. It takes a pretty strong magnet to erase susceptible media. Back in the days of 3.5” floppy disks, I used to keep a disk on my filing cabinet with a magnet. The disk was labeled “Rescue Disk” and, it worked. The magnet was strong enough to keep the disk attached to the cabinet but not strong enough to damage the data. For a hard drive (like the one you probably have in your PC), it takes a magnetic field like an MRI to damage the data. Media like solid state drives (SSD) or thumb drives, for example, are completely unaffected.
Myth: Private or “incognito” browsing means you’re anonymous online.
Truth: “Incognito” does not mean “invisible” or “untraceable.” It only means that the sites you visit won’t be logged in your browser and you can’t cache credentials.
Myth: By posting a disclaimer you can stop Facebook from using your pictures.
Truth: No, plain and simple. You own the pics, yes, but the Facebook terms of service you agreed to when you created your account says that they have the right to use them. Always remember that if the service is free, you are the product they are selling.
