You’ve probably seen references to TCP and UDP when setting up port-forwarding on a router or when configuring firewall software. These two protocols are used for different types of data.
Virtual machines are isolated containers, so the guest operating system in the virtual machine doesn’t have access to your computer’s file system. You’ll have to set up shared folders in a program like VirtualBox or VMware to share files.
RFID is a technology that surrounds us every day. It’s in our credit cards, passports, and some of the products we buy. Even many of our pets have RFID chips in them!

Ubuntu 14.04 LTS will “form the basis of the first commercially available Ubuntu tablets,” according to Canonical. We installed Ubuntu Touch 14.04 on our own hardware to see what those tablets will be like.

Backups on Windows can be confusing. Whether you’re using Windows 7 or 8, you have quite a few integrated backup tools to think about. Windows 8 made quite a few changes, too.
Netbooks — small, cheap, slow laptops — were once very popular. They fell out of favor — people bought them because they seemed cheap and portable, but the actual experience was lackluster. Most netbooks now sit unused.
Web browser bookmarklets allow you to perform actions on the current page with just a click or tap. They’re a lightweight alternative to browser extensions. They even work on mobile browsers that don’t support traditional extensions.

QWERTY — so-called because the letters at the top-left corner of the keyboard begin with QWERTY — is the most common keyboard layout. But some people think alternative keyboard layouts like Dvorak and Colemak are faster and more efficient.
