Explain a triode tube
It’s just like crackers to it has a negative side on the positive side but in the middle is a tube that block some of the negatives from getting over to the positive side and it’s just like a start stop button it’s called in and PN junction controls of the electrons can jump over to the other side this is also Morse code.Dass and in computers 01
Silicon
a semi conductor because it conducts electricity but not well electrons jump to silicon but they leave a hole where they once were in the electron behind it jumps into that spot but jumps to silicon and leaves a hole and that is why silicon on a semi conductor because it has missing electrons
Another name for npn junction
Transistor
Led
Light emitting diode
Mores law
Every two years you can double number of transistors same size as ice crystals

Server sided vs Client sided
Server side it is one another company saves your information for you also called cloud computing the benefits is that it’s easier and your computer doesn’t need to be powerful but there’s also a privacy concern they usually use a redundant server which means it saves your information at two different locations
Client side of computing is the machine you are using does everything this is good privacy wise but it’s also bad if you were to have a fire something and that’s why you can you stuff like memory card
LAN vs WAN
local area network
Wide area network
Why are weather forecasts only right 2 days in advance
Because the chaos theory says that there’s too many changing variables in weather so it can never be accurate
DARPA
Darker was a government industry that start of the Internet in the 1980s looking for a way to see if atomic bomb’s for possible they ended up making the Internet and everything to do an Internet gets chopped the tiny little pieces and put back together when they arrive a little pieces will always find them their way by themselves so if it’s going from New York to Los Angeles but Chicago is down they could go to Texas and then to Los Angeles but it always find its way
Explain crookes tube
CRT?
There is a battery leading up to a glass tube and the negative electrons from the negative side all start going towards a target and the electrons that missed the target cause a shadow on the glass called photo chemical code
Cathode Ray Tubes
