AOI logic, which uses AND, OR,and INVERTER(NOT) gates
NAND/NOR Logic, this uses only NAND or NOR gates respectively.
combinational circuit and sequential circuit
In some types of electronic design you may have Digital circuits also called Logic Circuits and Analog circuits. Each circuit may have separate power and ground lines. So you may see the notation on a schematic for Logic Ground or Analog ground.
Logic 0 and logic 1 are the two states in digital (or binary) logic. A binary numbering system has but two numbers: 0 and 1. In contrast, we use a decimal system with 10 numbers: 0 to 9. The area of algebra that addresses binary (2-state) logic is called Boolean. In Boolean a logic 0 may be refered to as 'low', 'off' or 'false'; a logic 1 as 'high', 'on' or 'true'. Boolean logic is the foundation of digital electronics.
All digital electronic circuits are composed of logic gates. Without logic gates there would be no digital electronics.

Digital Logic
Integrated circuits are produced with a myriad of functions today. Although early ICs tended to be digital logic circuits, there have been both analog and digital types throughout their history. Many ICs now combine digital and analog circuitry within a single package. So, an IC can be digital, analog or a hybrid of the two.

Digital Electronics deals with logic 1 and logic 0, where logic 1 is represented by one voltage and logic is represented by another voltage.(ie. it is a discrete representaiton of analog signals). The main advantage of digital signals over analog signal is that it is less prone to noise.
