TOPIC 2 : Data Transmission:- Error Detection, PARITY, CHECKSUM, ARQ
Data is frequently transferred from one device to another. The two devices could be in the same building or thousands of kilometres away.
Irrespective of the distance travelled, the transmission of data needs to be considered with respect to:
How the data is transmitted, how can errors following transmission be detected and can the data be recovered and the role of encryption to make sure data that falls into the wrong hands can’t be used.
It is also important to consider ways of checking for errors in data once it
has been entered into a computer.

Cambridge IGCSE Computer Science helps learners develop an interest in computational thinking and an understanding of the principles of problem-solving using computers. They apply this understanding to create computer-based solutions to problems using algorithms and a high-level programming language. Learners also develop a range of technical skills, and the ability to effectively test and evaluate computing solutions.

Studying Cambridge IGCSE Computer Science helps learners appreciate current and emerging computing technologies, the benefits of their use and recognise their potential risks. It provides an ideal foundation for progression to Cambridge International AS & A Level and is valuable for other areas of study and everyday life.

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 😊😊

[damianpious]

Hi Could you make some videos for CIE AS and A level computer science too? That would be really helpful 😊

[deadricxshoe]

your videos led me to be the topper in my mid term exam!! aiming for an A* in the CIE as well!! IA

[MintD]

Thank you sooo muchh! Amazing series and great explanations as well!

[technicalasad]

These Videos really helped me in my exam. THANK YOU

[Maceoneone]

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!

[avsanimates]

Dude your videos are awesome I have exam tommorow so this is a great help

[-stephenhawking-]

Can you please refer to the video for check digit and activity 2.7

[tawandabvunzawabaya]

great job man was failing to understand

[nadheema]

I still don't get how in checksum how 8 is the reminder...could explain it a little cleary

[gamershere]

Do you have any videos on programming for igsce CS 2023?

[NadaAhmed-nkmv]

I didn't understand the checksum 😩😩
