👉 In computer science, a nonserial (or serial) data format is one that does not have a fixed number of characters or bits in each byte. This means that while the size of the data varies between different devices, the sequence of bytes they represent remains constant. Nonserial formats are commonly used in hardware and software applications where the number of bits per byte is limited by the device's capabilities. For example, nonserial formats are often used in video encodings such as H.264
