Serial communication Serial communication In telecommunication and data transmission, serial communication is the process of sending data one bit at a time, sequentially, over a communication channel or computer bus. This is in contrast to parallel communication, where several bits are sent as a whole, on a link with several parallel channels. Serial communication is used for all long-haul communication and most computer networks, where the cost of cable and synchronization difficulties make parallel communication impractical. Serial computer buses are becoming more common even at shorter distances, as improved signal integrity and transmission speeds in newer serial technologies have begun to outweigh
Ports and harbours in South Africa ports have an important, perhaps exclusively military role. Some are just marinas. Ports and harbours in South Africa Ports and harbours in South Africa, A port is a location on a coast or shore containing one or more harbours where ships can dock and transfer people or cargo to or from land.
