Anyone else still have nightmares about the sound of a dial-up connection? It sounded like your computer was on the verge of exploding or being ripped apart. Thankfully, access to the Internet is now just one, almost silent click away, and what's more: it's a lot faster too. 15 years ago, you'd have to wait days if you wanted to download anything worth more than a few MBs. Now, the waiting times have been reduced to mere minutes, allowing for greater efficiency and better sharing all around. Plus, the ability to access the Internet without a dial-up connection has allowed people to work away from home or the office, and even enabled entire cities to provide widespread Internet access via Wi-Fi.
