OSI Model Real Examples

What is the primary purpose of the OSI model?

• To define specific network hardware components.

• To provide a theoretical framework for thinking about networking.

• To replace the TCP/IP model in practical applications.

• To encrypt data for secure transmission.

Which protocols are primarily associated with the Transport Layer of the OSI model?

• HTTP and FTP

• IP and ICMP

• TCP and UDP

• ARP and VLAN

What is a key difference between TCP and UDP?

• TCP is faster and simpler than UDP.

• UDP provides reliable, end-to-end communication with error checking, while TCP does not.

• UDP operates at the Application Layer, while TCP operates at the Transport Layer.
