Excuse me, but could you elaborate on the distinction between bit map and bit mask? As I understand, they both involve the use of bits, but I'm curious about the specific nuances that set them apart. Could you perhaps explain how they are utilized in different contexts and what makes one more suitable than the other for certain tasks? Your insight would be greatly appreciated.

The primary difference between bitmasks and bitmaps lies in their intended use and representation. Bitmasks are designed for efficient bit-level operations, allowing for quick checks and modifications of specific bit patterns. They are commonly used in low-level programming and system design to manage permissions, status flags, and other similar constructs.

Bitmasks and bitmaps are two commonly used constructs in computer science, each with distinct purposes and representations. Bitmasks are often defined as the "flipped" version of a set of bits, where the flipping operation is performed using the bitwise NOT operator (~). This approach allows for efficient manipulation of groups of bits, enabling functionalities such as permissions or flags.

On the contrary, bitmaps represent a set of variables, each of which is mapped to an individual bit within a larger binary structure. This mapping provides a direct and efficient way to represent and manipulate the states of multiple variables simultaneously, without the need for individual allocations or references.

Bitmaps, on the other hand, excel at representing large sets of boolean values or small integers. They provide a compact and efficient way to store and manipulate large numbers of variables, particularly when the majority of these variables are expected to be in a particular state (e.g., false or 0). This makes bitmaps ideal for tasks such as memory allocation, tracking changes, and managing sparse data.
