Units I: Computer Systems and Organisation

Encoding Schemes: UTF8 and UTF32
Concepts of Cloud Computing and Cloud Services (SaaS, Iaas, Paas), Cloud (public/private), Blockchain Technology

Unit II: Computational Thinking and Programming- 1

Decomposition: Concept, need for decomposing a problem, examples of problem-solving using decomposition.

For the convenience of the students, the Class 11 Computer Science Revised syllabus has been provided here in PDF format on Vedantu. This PDF can be downloaded for free from our mobile application and official website.

As we know, computer science is one of the most important core subjects in Class 11. It is part of the science stream of CBSE and it is most of our parents’ deepest wish that we would study this subject very well and get into a good engineering college to get great jobs in the budding corporate world.

Vedantu understands this, and also understands the rigour of studies that hits a student in the face as soon as Class 11 begins. It begins with the need for students to understand that the next year is the final board year and the preparations should begin for the same at the earliest. Thus, it is of imperative importance that all students of computer science in Class 11 take a good look at the syllabus of computer science class 11 to understand what kind of effort they will need to put into their studies.

There are 4 units in the CBSE Class 11 Computer Science Syllabus, and these units, as well as the subtopics which will be taught under them, are tabulated as follows.

Unit 1: Programming and Computational Thinking (PCT) - 1	Basics of Python programming Variables and methods to manipulate them Data types and operators Conditional statements Iterative computation and control flow Debugging Lists, tuples and dictionary Algorithm Strings

5. How will the Computer Science project for Class 11th be conducted by CBSE?

The project for the students of CBSE Class 11th will be formulated in such a way that the student has to apply most of the concepts studied in the syllabus for the completion of the project. During the 1st term of Class XIth, students will be required to prepare the synopsis of the project and submit it to the concerned faculty. This synopsis will contain only the documentation part. In the 2nd term of Class XIth, students will perform the final coding based on the synopsis they have submitted and will appear for the viva on the same subject. However, students will be allowed to modify their synopsis during the IInd term as well.
