Windows can encrypt entire operating system drives and removable devices with its built-in BitLocker encryption. When TrueCrypt controversially closed up shop, they recommended their users transition away from TrueCrypt to BitLocker.
Apple’s phone, tablet, and computer-tracking tools are the best in the business. You can remotely locate your device, disable it with a lock and message that persists through factory resets — the so-called “kill switch” — and wipe it.
Passwords can be reset or bypassed on every operating system. On Windows, Linux, and Mac OS X, you can gain access to a computer’s unencrypted files after resetting the password — the password doesn’t actually prevent access to your files.
Windows 7 and 8 create a special “System Reserved” partition when you install them on a clean disk. Windows doesn’t assign a drive letter to these partitions, so you’ll only see them when you use Disk Management or similar utility.
Older Android devices support USB mass storage for transferring files back and forth with a computer. Modern Android devices use the MTP or PTP protocols — you can choose which one you prefer.
Internet connection data caps are becoming more widespread in the US. Internet service providers may claim their data limits are good for “millions of emails,” but emails are small and HD videos on Netflix are much, much larger.
If you use remote desktop, remote file access, or other server software, you may leave your computer on at home or work when you leave the house. This uses more power. Instead, you could simply remotely power on your PC whenever you need to use it.
Coming from Windows, file extensions on Linux and Mac OS X can seem a bit strange. The operating system seems to know what files are without relying on the file extension — it does this using MIME types.
CyanogenMod is the most popular custom ROM for Android devices. While it’s an unofficial build of Android, it probably provides an experience closer to Google’s original vision than the software on your current Android phone or tablet does!
Regular backups are essential. Windows has integrated backup tools, Ubuntu has Déjà Dup, and Mac OS X has Time Machine. Time Machine backs up everything on your Mac, from system files to your personal files.
Android, iOS, Windows Phone, and BlackBerry 10 aren’t the only smartphone operating systems vying for a place in your pocket. There are other smartphone operating systems in development — and they’re all Linux-based.
Linux is easier to install and use than ever. If you tried installing and using it years ago, you may want to give a modern Linux distribution a second chance.
Android’s OTA (over-the-air) updates remove root access, forcing you to root them again if you depend on root-only apps. There are ways to preserve this root access, and re-rooting a device will be easier on some devices than others.
All mainstream desktop operating systems include powerful search features. They all offer the ability to create a “saved search,” which functions as a virtual folder. The saved search folder appears to contain the files that match your search.
Computers need cooling to remove the heat their components generate during use. If you’re building your own PC — especially if you’re overclocking it — you’ll need to think about how you’ll cool it.
Each network interface on your computer or any other networked device has a unique MAC address. These MAC addresses are assigned in the factory, but you can change, or “spoof,” MAC addresses in software.
System images are complete backups of everything on your PC’s hard drive or a single partition. They allow you to take a snapshot of your entire drive, system files and all.
Homegroups and network file sharing make it easy to access your PCs file from another PC on the same local network, but accessing your PC’s files over the Internet takes a bit more setup.
Laptops aren’t as easy to upgrade as desktop PCs. In fact, newer laptops are becoming harder to upgrade — but you still may be able to upgrade your laptop with more RAM or a solid-state drive.
Connect a Chromebook to a Windows network and you may be in for a surprise. Your Chromebook can’t access shared folders or network printers, whether they’re shared from a Windows, Mac, or Linux system.
It’s important to secure your wireless network with WPA2 encryption and a strong passphrase. But what sorts of attacks are you actually securing it against? Here’s how attackers crack encrypted wireless networks.
Hardware drivers are the software that allow your operating system to communicate with your hardware. Windows includes built-in drivers and automatically downloads new ones to make setup easier, but device manufacturers also provide their own driver packages.
Share a folder with Windows’ built-in sharing options and you can access it on an Android device, iPad, or iPhone. This is a convenient way to stream videos from your PC or access other files wirelessly.
Apple offers 5 GB of free iCloud space to everyone, but you’ll run up against that storage limit sooner than you’d think. Device backups, photos, documents, iCloud email, and other bits of data all share that space.
