Computer Science Class 12 Notes

Computer Science plays an important role in CBSE. Computer Science offers comprehensive exploration of computational thinking, computer networks and database management. CBSE offers both theoretical knowledge and practical knowledge. Computer science helps to understand the Python programming concepts, network principles and database systems, which helps students to face real-world challenges. The computer science focused on three main topics. Unit 1: Computational Thinking and Programming – 2, Unit 2: Computer Network, Unit 3: Database Management.

Unit 1: Computational Thinking and Programming – 2 helps the students to build a solid foundation in Python. Nowadays Python programming plays an important role in the field of software development, which helps to empower learners to create dynamic and reusable code blocks. In this unit students will be able to learn to create user-defined functions, arguments and parameters, what a global variable and local variable is, and how to create a file and its types. Students will also learn about data structures like stack operations and how to implement a stack using a list.

Unit 2: Computer Network covers core concepts of networking like the evolution of networks, data communication terminologies, the concept of communication, components of data communication, communication media, measuring capacity of communication media, IP addresses, and switching techniques. Students will also learn about transmission media, including wired communication and wireless media, and students will also learn about network devices like modems, Ethernet cards, repeaters, routers, hubs, gateways, switches, RJ45 and Wi-Fi cards.

Network topologies is also an important topic in computer networks, which include bus topology, star topology and tree topology. You will also learn about types of networks like PAN, LAN, WAN and MAN. This topic also includes web services like WWW, domain names, Hypertext Markup Language, URLs, web browsers, web hosting, web servers and extensible markup language.

Unit 3: Database Management. A database is the backbone of data storage; without a database, it is very difficult to store and retrieve data easily. In this topic students will learn about database concepts and its need, relational data models like attributes, tuples, domains, degrees, and keys like candidate keys, primary keys, alternate keys, and foreign keys.

Students will also learn about data definition language and data manipulation language, data types, how to create a database, how to use a database, how to display data, how to alter a table, how to drop a table, how to insert, delete, and select from a table, and students will also learn about distinct clauses, where clauses, in, between, order by, the meaning of null, is null, is not null, update commands, delete commands, aggregate functions like max, min, avg, sum and count, group by, having clauses, and joins. Students will also learn how to connect SQL with Python and different functions used in making connections between SQL and Python, like connect(), execute(), cursor(), fetchall(), fetchone(), etc.
