The Serial and Parallel communication processes play an important role in microprocessor. In Serial Communication in Microprocessor the data transmission takes place in serial way and In Parallel Communication in microprocessor the data transmission takes place in a single clock pulse.

In this article, we are going to discuss the Serial vs Parallel Communication in microprocessors with the other aspects related to it.

Serial Communication in Microprocessor

Serial Communication in a Microprocessor is a bit-by-bit operation. In this process, the data transmission takes place through a communication channel in a serial way. The microprocessor receives the data individually in the form of bits and makes it a complete data set. In simple words, Serial Communication in a Microprocessor takes place serially. Here is the complete process of Serial Communication in a Microprocessor as mentioned below.

Process of Serial Communication in Microprocessor

Here is the complete process of the serial communication in microprocessor as mentioned below.

• Staring Process of Communication: The data-sending process starts from a transmitter. The transmitter sends the first bit to the destination device or receiver.
• Data Transmission Procee: The transmitter starts to send the whole data bit-by-bit in a specific order. These messages are long and take a certain time to send.
• End Of Communication: When the transmitter finishes its work, it stops the bit transmission process.
• Optional Error Checking Process: This step is related to the receiver. The receiver checks the whole data which is known as the parity checking process. If there are some faults, the receiver asks the transmitter to send the data again.

Advantages and Disadvantages of Serial Communication in Microprocessor

Here are the advantages and disadvantages of the serial communication in microprocessor as mentioned below.

Advantages of Serial Communication in Microprocessor

• Serial communication in a microprocessor needs less wired connection than the parallel communication process.
• The structure of the serial communication process has low implementation costs and does not have complex hardware it.
• The data transfer method in the serial communication process is simple and transparent.
• Most of the telecommunication networks use this type of communication process for its simplicity.

Disadvantages of Serial Communication in Microprocessor

• Serial communication in a microprocessor is slower than the parallel communication process.
• The data transferring capability is low due to the lower bandwidth.
• The data needs to be organized properly as the serial communication process is not able to do that on its own.
• The sent data needs to be decoded properly after it reaches the destination to decrease the chances of error.

Parallel Communication in Microprocessor

Parallel Communication in a Microprocessor happens when the multiple data transmitted to the destination through the multiple channels. The basic bit structure of the Parallel Communication system is 8-bit which is known as byte. The data transfer process in parallel communication takes place in a single clock pulse. Each bit chooses its cable to travel to the destination. Here is the complete process of Parallel Communication in a Microprocessor as mentioned below.

Process of Parallel Communication in Microprocessor

Here is the complete process of the parallel communication in microprocessor as mentioned below.

• Staring Process of Communication: The data-sending process starts from a transmitter. The transmitter sends the first bit to the destination device or receiver.
• Data Transmission: The data can be divided into sets of multiple groups. These messages are complex and take a certain time to send through separate cables at the same time.
• Reception Of Data: The receiver gets the data and arranges it in the correct order to decode the message.
• End Of Communication: After the data transfer process, the receiver decodes the data and closes the process with a complete status.
• Optional Error Checking Process: This step is related to the receiver. The receiver checks the whole data which is known as the parity checking process. If there are some faults, the receiver asks the transmitter to send the data again.

Advantages and Disadvantages of Parallel Communication in Microprocessor

Here are the advantages and disadvantages of the parallel communication in microprocessor as mentioned below.

Advantages Of Parallel Communication in Microprocessor

• Parallel communication is faster than serial communication.
• Tt provides a high data transfer rate.
• This type of communication process creates a smaller number of errors.
• The data synchronization process is efficient as it sends multiple bits to the receiver simultaneously.

Disadvantages Of Parallel Communication in Microprocessor

• This type of communication process is costly as it needs more complex hardware to execute the process.
• The system transfers the data at a single clock time, but it suffers from the ‘skew’ due to the involvement of different wires.
• It can create a mess with the high-value data due to the latency factor present in it.
• The process transfers the data at the same time but through different cables. It can create overlapping errors in the receiver data.
