“Which OSI model layer handles congestion control in a network?”

"The Transport Layer the fourth layer of the OSI model manages congestion control ensuring reliable data transfer across networks. Protocols like TCP regulate data flow preventing network overload by adjusting transmission rates. This layer also handles error detection and correction enhancing communication efficiency. Understanding the Transport Layer’s role is vital for network engineers as it underpins robust data transmission in applications like web browsing streaming and cloud computing ensuring seamless connectivity in modern networks."
