amazing video i shared it my friends who were also having a problem with computer and now your channel is pretty popular for understanding computer. Thank you for making these 😊😊
@11:26 ? In terms of Checksum....I said in the video, any random number could have been chosen. In this example, I chose 16. Think of a checksum as a secret code that we put on a message or a file to make sure it doesn't get changed or messed up when we send it to someone. Here's how it works: We create a unique code (the checksum) from the message or file using a magic math formula. We send the message or file along with the special code to our friend. When our friend gets the message or file, they use the same magic math formula to create their own special code. Our friend compares their unique code to the one we sent. If the two special codes match, it means the message or file is safe and hasn't been messed up. But if they don't match, it tells us there might be a problem, and we might need to send the message again. So, a checksum is like a guard that checks if our message or file stays safe during its journey.
The checksum is like a special number that helps you make sure your encrypted message didn't get messed up during transmission. Here’s how it works: A list of numbers are sent with you message. You add up all the numbers in your encrypted message, and the checksum is the answer. When you send your message to someone, you also send the checksum. When they get it, they add up the numbers in your message and check if the checksum you sent matches the one they calculated. If they match, it means your message is probably safe and didn’t change during the trip. If they don’t match, something might be wrong with your message, and you might need to send it again. So, a checksum is like a guard that checks if your encrypted message is still the same and hasn’t been messed up during transmission.
1 day before exam 😀
Bahahahha frr
Me too 🎉
One 1h before exam😂
Us moment
Same
how did you get 8 as a remainder
There are 4 lots of 16 in 72 (e.g. 4x16=64) 72-64 = 8… there are 8 left over, this is the remainder
1night before exam how wonderful
I wish you the very best of luck 🍀

Hi…check out my other playlists…I have videos on programming and pseudocode
I still don't get how in checksum how 8 is the reminder...could explain it a little cleary
I am great full to you I learned every lesson from your videos and that helped me increase my grades 😊 Thanks to you❤❤❤❤
Is the divider going to be given to us if we get a question about the checksum on an exam? Also I love your videos, they are really helpful!
…yes you’ll be given the divider… thank you for your kind words

Why Divide by 16?
