Difference between || / &&

Sorry basic question I know but wondered what is the difference between using || or &&? Example for each would be:

if (OrderSymbol() == Symbol() && OrderMagicNumber() == OrderId2)
if (OrderSymbol() == Symbol() || OrderMagicNumber() == OrderId2)

|| means OR

&& means AND

if (OrderSymbol() == Symbol() && OrderMagicNumber() == OrderId2)

means both the symbol and the magic number must match

if (OrderSymbol() == Symbol() || OrderMagicNumber() == OrderId2)

means either the symbol or the magic number must match
