Computer Language Flashcards
Circuit
Multiple linked logic gates that perform complicated binary calculations
Binary
Communication that a computer use. 1 and 0
Logic gates
Electrical components that tell a computer how to use binary calculations
NOT Gate
Opposite gate. Input off = output on, input on = output off.
XOR Gate
When 1 input is on, the output will be on. Otherwise all is off.
OR Gate
Both inputs off = output off. Otherwise all is on.
NAND Gate
Both inputs on = output off. Otherwise all on.
Aka the “not-AND gate”
XNOR Gate
Matching inputs = output on. Otherwise all off.
Aka not-XOR gate”
AND Gate
Both inputs on = output on. Otherwise all is off.
ASCII
Oldest character encoding. Represents English alphabet, digits, and punctuation marks.
UTF-8
Allows us to store a character in more than one byte.
Abstraction
To simplify a complex system. Ex: steering wheel to driving a car or keyboard to a computer.
4 layers to computer architecture
