PARALLEL COMMUNICATIONS Meaning and
Definition
-
Parallel communications refers to a form of data transmission in which multiple bits of information are sent simultaneously over several channels or wires. In this method, each bit of data is transmitted on a separate wire, allowing for the efficient transfer of a large amount of information in a shorter period of time.
In this type of communication, the bits are organized in a parallel fashion, meaning that they are transmitted simultaneously in parallel channels. As a result, parallel communications have the advantage of faster data transfer rates and increased bandwidth as compared to serial communication methods. This is especially useful when dealing with large volumes of data or high-speed applications, as it reduces the time required to transmit information.
Parallel communications can be found in various applications, including computers, where they are used to send data between the central processing unit (CPU) and peripherals such as hard drives or printers. Additionally, parallel communication interfaces such as the printer port or SCSI (Small Computer System Interface) are commonly used for connecting external devices to a computer.
However, it is important to note that parallel communications also come with certain limitations. Maintaining synchronization between the parallel channels can be challenging, as any timing mismatch or delay can result in errors or data corruption. Furthermore, parallel communication requires a larger number of wires or channels, which can lead to increased complexity and cost in terms of cabling and hardware.
Etymology of PARALLEL COMMUNICATIONS
The word "parallel" in "parallel communications" comes from the Latin word "parallelus", which is derived from the Greek word "parallēlos". "Parallēlos" is a compound of "pará" (meaning "beside" or "parallel to") and "allēlōn" (meaning "of one another").
The term "parallel" is used in various contexts to refer to objects or lines that run alongside each other and never meet, emphasizing a similarity or comparison between them.
"Communications" is derived from the Latin word "communicare", which means "to share" or "to make common". It originates from "communis", meaning "common" or "general". The term "communications" refers to the transmission or exchange of information between individuals, devices, or systems.
