Lifi 

A new piece of technology which allows internet connection to be transferred using light rather than radio waves, it is alot safer as it will not go through walls and so people who arent inside the house/place you are in cannot use it, the lights can be dimmed so much that the human eye cannot see it while still providing internet connection more stable and faster than wifi.

Derick "why cant i get on your wifi?"
Bob "we have lifi, you need to be inside, and not looking through my window"

Lifi 

Li-Fi (Light Fidelity) is a bidirectional, high speed and fully networked wireless communication technology similar to Wi-Fi. Li-Fi uses visible light instead of microwaves, this allows it to transmit more data faster than traditional Wi-Fi.

That new LiFi is super fast bruv. Better than Wi-Fi anyday!

Lifi 

When the network says you have a connection or bars but is actually lying to you and doesn't work.

Dude 1: Fuck yea, I finally got connected to the wifi!
Dude 2: Nah man, it's just Lifi.

Lifi 

Stands for "Light Fidelity". Much faster then WiFi routers and whatnot, but it is not anywhere close to feasible yet.

Some companies were trying to implement LiFi.

Huh, I guess they blew $200,000 on Research and Development(R&D).

No-Lifing 

To do months of work within days, reject social invitations, and only leave the house to buy take-away because you must work hard to do well. Synonymous with IT certifications or playing computer games.

Sorry dude, I cant come out tonight. I've gotta no-life Cisco, as I've only got 5 days left to complete the last 6 exams of my certification.

Yea man, the only way your going to finish that work is by No-Lifing it.
