Today, we'll discuss abstraction, commonly known as description. There are two methods of description. These are symbolic language and body language. The abstraction is an important part for developing a computer. This is originated from the symbolic system in the computer system. The origin of symbolic system was developed when people try to communicate with each other. The symbolic language took communication to wider people and popularity group. The other part of abstraction is the body language. People accepted body language as well. The physical movement facilitates the development of sign language, which popularly became hand words. This form originated from early human attempts to communicate, leading to the development of systems like the symbolic system used in computers. It allows communication to reach a broader audience and is crucial for computer development. This method of description was also widely adopted. Physical movements associated with body language facilitated the development of sign language, commonly referred to as "hand words". Generalization is the process of finding similarities (the obvious) in repeated patterns, and hiding the similarities behind an abstraction. Specialization is the process of using the abstraction, supplying only what is different (the meaningful) for each use case.
