Difference Between USB 2.0 and 3.0 Port?

Hi, I'm looking for a new laptop (Black Friday shopping), and I'm looking at a Toshiba. (C55-A5285/049562).It has three USB 2.0 ports and one USB 3.0 port. I'm a little bit confused but from what I've read they're not different sizes, 3.0 is just faster and better? Do I have this right? All I'd really be looking at connecting are some USB drives (memory sticks, etc.) and my cable for my iPhone.

Thanks so much for your help, and happy Thanksgiving!

Dropped Iphone 5s off my bed: Can it be damaged internally?

Okay so I had my 5s on my bed next to me and I was careless and it fell off my bed. It fell like 3 ft onto wooden floor. I had my OtterBox Commuter case on it. It made a pretty loud sound when it hit the floor. I checked the phone and it has no cracks or chips that I could see. Can the phone have some internal damage. I've only had it for a month. I'm afraid that something might be wrong with it.

Added (1). Everything work so i'm assuming its okay

Added (2). It landed on its back

I cracked the back of my iPhone? - 1

On Thanksgiving too. I threw my phone on my bed went to go take a shower but it fell hard and I picked it up the back of my phone had cracks coming from the top down to the bottom. My camera and flashlight are not cracked. But I've had this phone for about two years and the two-year warranty is up I should I feel nervous or no

This is the first time I cracked my phone my iPhone 4s. What should I do just let it go should I put protection on it now should I do that highlighted thing and color in the back it looks cool should I even tell my parents or no. The front of my phone is not harmed either

Yeah I guess I overreacting for nothing but whatever. I'm jacked but I'm soft

Can a computer catch a virus from an iphone?

My iphone is in recovery mode and the only computer that has iTunes in our household is my mothers mac. For work. My step-dad is frantically saying that if there's a virus it could cause harm to my mothers computer, therefore I should not plug it in to hers. The recovery mode has already started and it says it will take 5 hours.So, I was wondering, if my phone HAS a virus, which we aren't sure about if it even has one, could it transfer onto the computer through the recovery mode?
