A typical B.Tech in Computer Science (or related) curriculum includes Computer Networks as a core subject. This subject covers fundamental concepts of networking, including network architecture, protocols, security, and various technologies. Specific topics often include network models (OSI, TCP/IP), data transmission, routing, congestion control, and network security. Detailed syllabi can vary by institution, but common themes include the theoretical foundations and practical applications of computer networks. 

Here's a more detailed breakdown of what's usually covered:

Core Concepts:

• Network Models: Understanding the OSI model and TCP/IP model for layered communication. 
• Data Transmission: Exploring different transmission media, encoding techniques, and multiplexing methods. 
• Error Detection and Correction: Learning about techniques to ensure reliable data transfer. 
• Media Access Control: Understanding how multiple devices share the same communication medium. 
• Switching: Exploring different switching techniques like circuit switching and packet switching. 
• Routing: Learning how data packets are forwarded from source to destination. 
• Congestion Control: Understanding techniques to manage network traffic and prevent congestion. 

Network Layers and Protocols:

• Application Layer: Studying protocols like HTTP, FTP, DNS, etc.
• Transport Layer: Focusing on TCP and UDP protocols.
• Network Layer: Exploring IP addressing, routing protocols, and ICMP.
• Data Link Layer: Understanding MAC addressing, error control, and flow control.
• Physical Layer: Dealing with the physical transmission medium. 

Network Security:

• Cryptography: Learning about encryption, decryption, and digital signatures.
• Authentication and Authorization: Understanding how to verify user identities and grant access to resources.
• Intrusion Detection and Prevention: Learning how to protect networks from malicious attacks. 

Other Areas:

• Wireless Networks: Exploring different wireless technologies and protocols (e.g., Wi-Fi, Bluetooth).
• Mobile Computing: Understanding the principles of mobile networking.
• Network Programming: Learning how to develop network applications.
• Network Management: Exploring tools and techniques for managing network resources.
