For example, when integer value 16,706 is transferred in ASCII and binary formats
are compared.
As shown in the figure below, five bytes are required to transfer the data in ASCII
format. In this case, the ASCII code must be converted to binary code. On the other
hand, only two bytes are required to transfer the data in binary format. In this case, the
data format does not need to be converted. Therefore, binary transfer is usually used
for high-speed data transfer.
