Do you think it might be a bad CMOS battery or maybe a bad motherboard? [Read more…]
Q&A: What’s the difference between Bluetooth and WiFi?
Question from Marvin: After using a flip phone for years, I finally decided it was time to upgrade to a smart phone.
I found a good deal on a new iPhone at Best Buy, so I bought one. I like the phone ok, but some things about it are really confusing.
For example, my phone’s user manual says it supports both Bluetooth and WiFi wireless connectivity.
What is Bluetooth and how is it different from WiFi? [Read more…]
