🎯 Key Takeaways for quick navigation: 00:00 🎯 Introduction to Error Detection and Correction - Error detection and correction are essential topics in the field of computer networks. 00:29 🧐 Identifying Errors in Data Transmission - Errors in data transmission can occur due to various factors, including long distances, energy loss, attenuation, environmental effects, and more. - Error detection methods are used to identify the presence of errors in transmitted data. 01:51 🛠️ Error Detection and Correction Fundamentals - Error correction is an advanced step beyond error detection, allowing for pinpointing and fixing errors. - In computer networks, error detection and correction take place primarily in the Transport Layer and Data Link Layer. 02:21 📊 Types of Errors in Data Transmission - The types of errors, such as single bit errors and burst errors, depend on the application and context. - Single bit errors involve changes in individual bits, while burst errors affect multiple bits in a sequence. 04:44 📉 The Length of Error and Burst Errors - The length of an error is determined by the duration during which bits are corrupted, even if it's not continuous. - Burst errors, involving multiple bit changes, are more common due to longer error durations. 06:16 ⏲️ Error Duration and Bandwidth - The duration of an error is inversely related to the bandwidth of the channel, with faster channels requiring shorter error durations to result in single bit errors. 08:39 🔍 Calculating Corrupted Bits Based on Error Duration - The number of corrupted bits due to an error duration can be calculated by multiplying the duration by the channel's bandwidth. 09:08 🕵️ Methods for Error Detection and Correction - Error detection methods include Parity, Checksum, and CRC (Cyclic Redundancy Check). - Hamming Codes are commonly used for error correction, all of which rely on redundancy for error handling. 10:10 🔄 The Role of Redundancy in Error Detection - Redundant bits are essential for error detection and correction, ensuring the integrity of data transmission in computer networks.

Thank you! Anyone who can explain how does '101' convert to decimal 5 or '100' to decimal 4 , I would be grateful. What topic would I need to study to understand this conversion system? Thanks. Edit: 25/02/22 The answer to my question, I found in Lec-42 of the same series.

[@shreechandansamal5206]

This problem belongs to binary to decimal conversion.

[@saranshpandey3056]

2^2*1 + 2^1*0 + 2^0*1 = 5

[@rakeshkarmakar8681]

Sir ... suppose that there is an error in 3 bits .for example 1110011->1011010.Then what should be the length of the error?

[@smitbhamwala]

then length of error is 6 bits bcoz first error is in 2nd bit and last error is in last bit . So count every bit from 2nd bit to last bit.

[@jatilyadav4000]

Amazing video
