high and low side

I don't understand the meaning of "high and low side" in this paragraph. What does it exactly mean? What type of output devices? Perhaps cheap and expensive devices?

In a Class A amplifier, the output devices
are continuously conducting for the entire
cycle, or in other words there is always bias
current flowing in the output devices. This topology
has the least distortion and is the most
linear, but at the same time is the least efficient
at about 20%. The design is typically not
complementary with a high and low side output

Thanks in advance
