What is the purpose of the transport layer in the OSI model, and how do devices like firewalls and load balancers operate at this layer?
The transport layer is a part of the OSI (Open Systems Interconnection) model, which ensures communication, between devices in a network.
Its key role is to ease data transfer by offering services such as breaking down data into smaller segments for efficient transmission and reassembling them at the receiving end.
Additionally, it manages error detection and correction to maintain the integrity of transmitted data.
The transport layer also supplies flow control mechanisms to regulate the pace of data exchange between devices.
It is worth mentioning that firewalls and load balancers although not technically part of the OSI model itself play roles in managing network traffic, security, and performance at this layer.
