The PC business is pretty standardized these days. People know they want a computer, a display, a mouse, a tablet. Many of those people know they’d rather have a major brand for the reassurance of support and security. So, the struggle for the PC companies is to figure out some way to stand out and thrive selling similar stuff to people who usually know what they want. CES is a great place to do that. HP’s mission is to bring something extra to its products—to add a unique premium to their products. This year, 5G is an obvious value add for PC vendors and it’s a key enabler for the Always-On computer. HP’s cute new DragonFly, a “business convertible,” comes with a 5G radio. And, HP has another twist on connectivity. HP’s very portable DragonFly has integrated Tile support. Tile tracks connected devices through their Bluetooth signal to provide location information. In fact, that Dragonfly is a great example of the many ways HP is adding value in engineering as well as design appeal, and we’ll be returning to that. But first, displays. CES just wouldn’t be CES without displays—okay, and cars, weird gadgets, and controversial keynoters (seriously, Ivanka?), home entertainment, spe...

What’s the Difference Between These Ethernet Cables, and Will They Make My Network Faster?

Dear Lifehacker, I finally took your advice and went completely wired on my home network using a bunch of Ethernet cables I had lying around. Some are Cat5, and others are Cat5e. Is there a difference? Is one faster than the other? What should I use? Dear Confusing, Congratulations on wiring up your home—it’s not always an easy task, but it feels great once you finally do it (especially if you’re using the network to stream video, play games, transfer data between computers, and so on). There is, in fact, a difference between all those network cables. They look very similar from the outside, and any of them will plug into an ethernet port, but they do have some differences on the inside. If you aren’t sure what type of cables you have, look at the text printed on the cable—usually it will tell you what type it is. The differences between each type of cable can get very complicated and have a lot to do with network standards, but we’ll tell you just what you need to know: how they’ll practically affect the speed of your home network. Category 5 cabling, also known as Cat5, is an older type of network cabling. Cat5 cables were made to support theoret...
