Final answer:
Computers and communication systems transfer information using data codes, represented in binary form as ones and zeros, enabling efficient and clear digital communication.
Step-by-step explanation:
Computers and communication systems use data codes to represent and transfer information between computers and network systems. These data codes often consist of a sequence of binary ones and zeros, with each one or zero representing one bit of data. This digital representation of data facilitates clear transmission, even with weak signals, and allows the use of algorithms to compress data, increasing transmission efficiency within frequency ranges. The establishment of standardized communications protocols, such as those stemming from the development of ARPANET and the subsequent emergence of the Internet, have been pivotal in enabling the global exchange of information.
