can anyone tell me what the difference is between sending a transaction of token xyz from a to b and transfering token xyz from a to b

if i want to transfer eth from a to be i need to signtx etc. if i want to send token from a to b i can do it with transfer or transfer from?

i assume i cannot even do a send on a smart contract if there isnt the function for it right

You can only use transferfrom if that person called the approve function

ok, i see
