![]() ![]() ![]() Keyboard and mouse cables and ports are almost invariably serial-such as and and. The cables that carry this data (other than 'the' serial cable) and the they plug into are usually referred to with a more specific name, to reduce confusion. Practically all long-distance communication transmits data one bit at a time, rather than in parallel, because it reduces the cost of the cable. Main article: Many serial communication systems were originally designed to transfer data over relatively large distances through some sort of. Serial computer buses are becoming more common even at shorter distances, as improved and transmission speeds in newer serial technologies have begun to outweigh the parallel bus's advantage of simplicity (no need for serializer and deserializer, or ) and to outstrip its disadvantages (, interconnect density). Serial communication is used for all long-haul communication and most, where the cost of and difficulties make parallel communication impractical. This is in contrast to, where several bits are sent as a whole, on a link with several parallel channels. In and, serial communication is the process of sending one at a time, sequentially, over a. ![]()
