# What is Logic?

Logic is the science of correct thinking.

A classic definition is new and necessary reasoning. It's new because you didn't know the item before, and necessary because a correctly formulated syllogism has to be true if the bases are true.

This syllogism is a well-known example:

All men are mortal.

Socrates is a man.

Therefore, Socrates is mortal.

We took two axioms and made a new and necessary conclusion.

### What are the blocks in logic gates?

The blocks in a logic gate depends on the logic family we use. A logic gate is designed using a specific logic family. The logic families can be DTL, TTL, CMOS etc. The blocks are different for different logic families. The various blocks in various logic families are: Diode logic: diodes and resistors DTL logic : diodes and resistors TTL logic : transistors and resistors NMOS logic: only NMOS FETs PMOS logic: Only PMOS FETs…

### What does TTL applies mean?

TTL is a logic family. A logic family is the set of logic gates designed using a specific approach. Or simply speaking, logic family is the way of implementing logic. TTL stands for transistor - transistor - logic. It involves transistors (BJT) to implement logic. TTL applies means TTL logic family is used or can be applied in that specific application.

### What is logic 0 and logic 1?

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…
