ELI5: Explain Like I'm 5

John Cioffi

John Cioffi is a very smart man who knows a lot about something called telecommunications. This means he helps people talk to each other far away using things like telephones and computers.

John helped create something called DSL, which is short for Digital Subscriber Line. DSL makes it so people can use the same line for both talking on the phone and using the internet at the same time. This is really cool because before DSL was invented, people had to use separate lines for the phone and the internet.

John also helped create something called vectored DSL. This makes it so people can get better internet speeds and have less problems with the internet cutting out or being really slow.

In short, John Cioffi is a really smart guy who helped invent important ways for people to talk to each other and use the internet, making things easier and faster for everyone.
