Therefore, parallel processing increases the throughput as well as improves reliability. Most modern computers support parallel processing to increase performance.
We can understand the functionality of parallel processing using the following example. In a supermarket, there are multiple queues, and there is a cashier for each queue. Each cashier bills the products of the customers in his own queue. Serial processing is a type of processing in which one task is completed at a time and all the tasks are executed by the processor in a sequence.
Parallel processing is a type of processing in which multiple tasks are completed at a time by different processors. Thus, this is the fundamental difference between Serial and Parallel Processing.
A major difference between serial and parallel processing is that there is a single processor in serial processing, but there are multiple processors in parallel processing. Therefore, the performance of parallel processing is higher than in serial processing. In serial processing, the workload of the processor is higher. This leads to a faster communication between the sender and receiver. But for connecting multiple lines between sender and receiver multiple connecting unit are to be present between a pair of sender and receiver.
And this is the reason why parallel communication is not suitable for long distance transmission, because connecting multiple lines to large distances is very difficult and expensive. So it is clear that utilizing multiple lines for data transmission in case of parallel communication is advantageous as it offers faster data transmission. But as the same time it is disadvantageous when considered in case of cost and transmission distance.

Skip to content The crucial difference between serial and parallel communication is that in serial communication a single communication link is used to transfer the data from an end to another.
The whole byte is transmitted in a single clock cycle which makes it relatively faster than serial communication. It can send 8 bits of data at the same time the serial mode can send one bit. But due to multiple channels required for each bit, parallel communication needs multiple wires to carry the data. It is more expensive and requires more space to accommodate those wires. Each byte sent must be received in the same pattern, which is why it is necessary to design the connectors in a design.
This increases the complexity of designing its connectors. Also due to multiple channels, the data is more vulnerable to interference such as crosstalk and skewing.
The former means when the bits skip into another channel while the later means the receiver has to wait for the slowest bit to complete the transfer. In both cases the signal gets distorted. Therefore, it is not efficient for long-distance communication but they are best for short-distance communication between various internal peripherals of any digital system.
The parallel communication provides quick and high-speed transmission but at high cost and requires more wires. Thus it is a better choice for short-distance communication to reduce the installation cost. While the serial communication seems slower and it is then the parallel communication but it is faster at long distances and at high frequencies.
