Parallel communication a time. If both channels operated at the same clock speed, the parallel channel would be eight times faster. A parallel channel may have additional conductors for other signals, such as a clock signal to pace the flow of data, a signal to control the direction of data flow, and handshaking signals. Parallel communication is and always has been widely used within integrated circuits, in peripheral buses, and in memory devices such as RAM. Computer system buses, on the other hand, have evolved over time: parallel communication was commonly used in earlier system buses, whereas serial communications are prevalent in
Serial memory processing been found that confusability in the items in the memory set can affect item recognition. Auditory and phonological confusability in the memory set is associated with increased encoding time. As well, visual confusability in the memory set is associated with increased comparison time. It is shown that the modality of the items can affect different processes in item recognition. Serial memory processing Serial memory processing is the act of attending to and processing one item at a time. This is usually contrasted against parallel memory processing, which is the act of attending to and processing all items simultaneously. In short-term
