Checksum error detection is one of the most popular methods for identifying errors in transmitted data. The process involves dividing the main data into equally sized segments called fixed frames and using a 1โ€™s complement (checksum) to calculate the sum of these segments. The overall sum is then sent with the data to the receiver is called a packet.
At the receiverโ€™s end, the same process is repeated as discussed above and if all zeroes are obtained in the sum at the receiver, the data is correct and error otherwise. We discussed the topic with two problem examples in depth for better understanding.

Prim's algorithm aims to find a minimum spanning tree of an undirected edge-weighted graph. This algorithm starts with a single node and travels through several adjacent or connected nodes to explore all connected edges on the way. The spanning tree should be connected, it also finds a minimum spanning tree. MST is a greedy algorithm that adds the lowest weighted edge but does not form a cycle. We discussed every topic in depth for better understanding.

Hello everyone and welcome back after Eid Ul Azha. I hope you enjoyed your Eid very well. Now it's time to start our study.

In this video, you will learn about a small definition of Checksum and error detection. You all know it is a significant topic of Data Communication. The full video will be uploaded on this page real soon. You can also check the full video of this lecture on our YouTube channel ๐‘ญ๐’“๐’†๐’† ๐‘ช๐‘บ๐‘ฌ ๐‘ณ๐’†๐’‚๐’“๐’๐’Š๐’๐’ˆ.

This tutorial has discussed about Baseband Transmission using Limited Bandwidth in terms of Data Communication, one of the most popular topics in Data Communication in Bangla. Low pass channel is a channel with a frequency that starts from zero (0). A digital signal is a composite analog signal with infinite bandwidth. The LAN is a common example of baseband signaling. We studied two Approximations (Rough Approximation and Better Approximation) for bit rate and bandwidth calculation.

In this tutorial, we have discussed, Bandwidth of a composite (periodic and non-periodic Signal), one of the most popular topics in Data Communication in Bangla. The bandwidth of a composite signal refers to the difference between the highest and lowest frequencies contained in that signal. We explained about bandwidth and then we solved three numerical problems with frequency spectrum analysis.

In telecommunications, bit-rate is the number of bits that are conveyed per unit of time or per second. The bit rate is expressed in the unit bit per second (bps), in most cases in conjunction with prefix such as kilo, mega, giga, or tera. We explained about bit rate and then we solved three numerical problems related to bit rate. We discussed every topic in depth for better understanding.
