Eight bits are required to store and send all three numbers. Three bits can store 2·2·2 values. So to store 3 values, you need at least two bits.
What are bits ?The smallest piece of data that a computer can process and store is a bit (binary digit). Similar to an on/off light switch, a bit is always in one of two physical states. Usually a 0 or 1, the state is represented by a single binary integer.
Computers interpret our intentions and process information based on how those "instructions" are represented as bits.
The majority of systems process and store data in bytes, even if a computer may be able to evaluate and alter data at the bit level. A byte is an eight-bit string that is regarded as a single entity. Bytes are always used to refer to a computer's memory and storage.
The place value, also known as the bit value, is the value that is assigned to each bit in a byte. Based on the individual bits of a byte, the place values are utilised to interpret the meaning of the byte as a whole. In other words, the byte values show which character corresponds to each byte.

what term describes the process of creating a program specific details first and then combining them into a whole
A computer programming paradigm known as object-oriented programming (OOP) arranges the design of software around data or objects rather than functions and logic.
The object-oriented programming (OOP) paradigm for computer programming organizes software's architecture on data or objects rather than around functions and logic. A data field with specific traits and behavior is called an object.
In OOP, the objects that programmers want to modify are given more weight than the logic required to do so. Large, complex, and frequently updated or maintained programs work well with this development approach. This includes both design and production software as well as mobile applications. Software for manufacturing system simulation, for instance, can use OOP.
The organization of an object-oriented program makes the method advantageous in collaborative development, where projects are divided into groups. The benefits of efficiency, scalability, and reused code are also provided by OOP.
