# Tip The CPU is often referred to as the brain of the computer.<ref name="ref_c810f8bd">[https://www.computerhope.com/jargon/c/cpu.htm What is CPU (Central Processing Unit)?]</ref>
# However, it is more appropriate to refer to software as the brain and the CPU as a very efficient calculator.<ref name="ref_c810f8bd" />
# Note Many new computer users may improperly call their computer and sometimes their monitor the CPU.<ref name="ref_c810f8bd" />
# When referring to your computer or monitor, it's proper to refer to them as either the "computer" or "monitor" and not a CPU.<ref name="ref_c810f8bd" />

# In Microprocessors, all the CPU components are accommodated on a single small IC and due to this design clock rates of these CPU goes up to several GHz.<ref name="ref_619d0d37" />
# Intel 4004 in 1971 and Intel 8080 in 1974 dominated all other CPU implementation.<ref name="ref_619d0d37" />
# All computers years ago were called "mainframes," and the CPU referred to the entire computer.<ref name="ref_c4926f70">[https://www.pcmag.com/encyclopedia/term/cpu Definition of CPU]</ref>
# Also called the "processor," the CPU is made up of the control unit, which executes the instructions, and the ALU, which performs the calculations and logical operations.<ref name="ref_c4926f70" />
# See microprocessor control unit and ALU Technically, the CPU, clock and main memory make up a computer.<ref name="ref_c4926f70" />
