Packetization is the process of dividing data into small packets or units to transmit them efficiently over a network. There are various synonyms for the word packetization, such as fragmentation and segmentation. Fragmentation refers to the process of dividing a larger data unit into smaller pieces to allow easy transmission over a network. Segmentation, on the other hand, involves dividing the data stream into separate segments or packets for efficient data transfer. Other synonyms for packetization include encapsulation, reassembly, and serialization. Each of these terms is used in different contexts to describe the process of breaking down data into smaller parts for efficient transmission.
