TOPIC 1 : Data Representation and the first study area: data storage and compression - 1.3(b) Understand the need for data compression & Lossy and lossless compression methods

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.

I have an exam tomorrow on the whole chapter one, and I could barely understand the teacher so thank you so much man. you literally saved me

[MuhammadHishaamFarooq]

Too good! I have an exam tmr this video helps a lot.

[raza]

thanks for uploading these videos they really help me in my exams and every day studies

[T-ji]

thanks dude...great for last minute revision

[Maria-kpvy]

Sir, thank you so much for the video. It is truly very helpful.
However, I have some small doubts. For colored images, how do we determine how much red, green and blue a color has? Also, in Example 2, how did they write the values as 255? In the exam, will they tell us how many components of RGB a color has?

kindly share lecture on network hardware.

im doing the oct/nov/2022 session is this part of my syllabus because under data representation 1. 1.3 the last thing it says is Data Storage but nothing abt data compression

[nadine]

Is logic gates included in paper 1 exam ?

[matrix]

Is there a difference between mp4 and mp3 is it like more advanced or better quality of the sounds
