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
Serial killer that serial killers are always white might have become "truth" in some research fields due to the over-reporting of white serial killers in the media. According to some sources, the percentage of serial killers who are African American is estimated to be between 13% and 22%. Another study has shown that 16% of serial killers are African American, what author Maurice Godwin describes as a "sizeable portion". A 2014 Radford/FGCU Serial Killer Database annual statistics report indicated that for the decades 1900–2010, the percentage of white serial killers was 52.1% while the percentage of African American serial killers was 40.3%.
