The Product of Sum (POS) expression comes from the fact that two or more sums (OR's) are added (AND'ed) together. That is the outputs from two or more OR gates are connected to the input of an AND gate so that they are effectively AND'ed together to create the final (OR AND) output.

Understanding Product-of-Sum in Boolean Algebra
In Boolean algebra, the term "Product-of-Sum" refers to a specific structure of logical expressions involving both AND and OR operations. Let's break it down:
Definition
- Product-of-Sum indicates a combination of multiple OR operations that are then combined using an AND operation.
Structure
- The expression consists of several groups, where each group is an OR function. For example, if we have two variables A and B, the Product-of-Sum form could be represented as:
(A + B)(C + D)
Here, (A + B) and (C + D) are both OR functions.
Operation Explanation
- In the expression above:
- A + B represents an OR operation between A and B.
- C + D represents an OR operation between C and D.
- The overall expression is then multiplied (ANDed) together, hence the term "Product."
Why Option A is Correct
- Option A states "AND function of several OR functions," which accurately describes the Product-of-Sum structure.
- Each term inside the parentheses (the OR operations) is combined using an AND operation, aligning perfectly with the definition.
Contrast with Other Options
- Option B, "OR function of several AND functions," describes a different structure known as Sum-of-Product.
- Other options (C and D) do not correctly represent the Product-of-Sum structure at all.
Conclusion
- Understanding the Product-of-Sum form is crucial for analyzing and simplifying Boolean expressions in computer science and digital logic design.
