The basic latch consists of two inverters.

Explanation:
1. What is a latch?
A latch is a basic electronic circuit that is used to store and retain a single bit of data. It is a fundamental building block of memory elements in digital circuits.

2. Structure of a latch:
A latch typically consists of two cross-coupled inverters, also known as a flip-flop. These inverters are connected in a feedback loop, creating a circuit that can store and retain a value.

3. Understanding inverters:
An inverter is a logic gate that takes an input signal and produces an output that is the complement of the input. In other words, if the input is high (1), the output will be low (0), and vice versa.

4. How the latch works:
- Initially, both inverters are in a stable state, with one inverter outputting a high (1) and the other outputting a low (0).
- When an input signal is applied to one of the inverters, it causes a change in the output of that inverter.
- This change in output is then fed back to the other inverter, causing it to change its output as well.
- The feedback loop continues, with the output of one inverter influencing the output of the other, until a stable state is reached.
- The latch can retain this stable state until the input signal changes again.

5. Significance of two inverters:
- The use of two inverters in a latch provides stability and control over the stored value.
- The feedback loop created by the two inverters ensures that the latch remains in a stable state even when the input signal changes.
- By using two inverters, the latch can effectively store and retain a single bit of data.

In conclusion, the basic latch consists of two inverters connected in a feedback loop. This arrangement allows the latch to store and retain a single bit of data, making it a fundamental component of digital circuits.
