Why NAND and NOR gates are more popular what are they commonly known as?

NAND and NOR gates are more popular as these are less expensive and easier to design. Also other functions NOT AND OR can easily be implemented using NAND/NOR gates. Thus NAND NOR gates are also referred to as Universal Gates.

Why are NAND and NOR gates the most used logic gates and categorized as universal gates?

The NAND & NOR gates are called universal gates because they perform all the logical operations of basis gates like AND, OR, NOT. Answer: NOR AS AND An AND gate gives a 1 output when both inputs are 1; a NOR gate gives a 1 output only when both inputs are 0.

Which is better NOR or NAND?

Both NAND and NOR are classified as universal gates, but we see that NAND is preferred over NOR in CMOS logic structures. NAND gate has better ratio of output high drive and output low drive as compared to NOR gate. Hence NAND gate is preferred over NOR.

Why are NAND and NOR universal gates?

∴ NAND and NOR gates are called universal gates because they can be combined to produce any of the other gates like OR, AND, and NOT gates. Hence the correct option is option (B). Note: NAND and NOR are economical and it is commonly used in many integrated circuit packages.

Why are NAND and NOR gates cheaper?

In most applications, NAND gates and NOR gates are the most commonly used, because they use less transistors internally than other types of gates do, which makes them cheaper to produce and buy. Also, NAND gates can actually be used to build any type of Boolean operator we need.

Are NAND gates faster than and gates?

In the industry NAND is preferred over NOR most of the time. NAND is a better gate for design than NOR because at the transistor level the mobility of electrons is normally three times that of holes compared to NOR and thus the NAND is a faster gate. Additionally, the gate-leakage in NAND structures is much lower.
