Lesson 62 of 62By Simplilearn
With the increase in the data and information exchange over the network channels, the need to detect any error or damage to the transmitted data becomes a necessary part of the process, and this issue is resolved using the checksum method.
This article on ‘What Is Checksum?’ will look into multiple steps involved in working the network checksum model.
The checksum is a network method to check for any error or damage to the data transmitted to the sender side from the sender side. The checksum method applies the bit addition and bit complement method to perform the checksum implementation.
The need to apply checksum or any other error-detection method is done simply to identify the damage to the data when it's being transmitted over the network channel.
The checksum uses the Checksum Generator on the sender side and the Checksum Checker on the receiver side.
Steps involved in the checksum error-detection method:
Let’s use an example to implement the checksum method and consolidate our understanding of the network principle.
For the given data value 11001100 10101010 11110000 11000011, perform the checksum method.
1. The first step is to perform the bit addition of the given data bits at the sender side.
Note: The extra carry bits are added to the summation result.
2. Perform the 1’s Complement for the bit addition result, thus obtaining the checksum value.
3. Integrate the checksum value and the original data bit and begin the data transmission to the receiver.
4. The receiver side will begin the Checksum Checker method, repeat the bit addition, and perform the 1’s complement.
5. If the complement result is 0, the data received is correct and without any error.
In this article, we looked into the information related to working the error-detection network method, the checksum method.
You can refer to Simplilearn’s Cyber Security Expert course to further understand the working of the checksum method. By completing this professional course, you’ll become more proficient with terms related to network principles and more experienced in performing the checksum method.
