How many sequential memory cells with target returns are required to display the target?

In understanding the number of sequential memory cells required to display a target, it's important to note how data is processed and represented in systems. The correct answer pertains to how binary data is structured for representation in memory.

When displaying a target, especially in digital systems, each memory cell can typically represent a single bit of information (either 0 or 1). To achieve a full representation of a target requires enough cells to accommodate all the bits necessary for that target's data.

For instance, if a target consists of data that can be represented in binary, the number of bits required is crucial. In many systems, one memory cell is usually not sufficient, as it would only hold the information of a single bit, which is inadequate for most targets that require more complexity and detail.

The concept of sequential memory cells suggests that when there is a need for more than just one bit, cascading or stacking additional memory cells becomes necessary. The answer being two indicates that two sequential memory cells are sufficient to cover the binary representation needed for a simpler target display, such as representing numbers (where 2 cells can represent values ranging from 0 to 3 in binary).

Thus, in this context, the answer involving two memory cells aligns with the basic principles of binary
