Study Notes
Network Communication Issues
- The primary issue preventing the opening of a file is not specified, but the question implies it may be related to browser version or network communication.
Browser and Network Communication
- A message about an unsupported browser version is displayed because the browser being used is outdated or incompatible with the website or application.
OSI Model
Network Layer
- The network layer provides logical communication between application processes running on different hosts.
Transport Layer
- The responsibility of the transport layer is to provide reliable data transfer between devices.
- The transport layer is responsible for communication between hosts.
- At the sender side, the transport layer provides functionality to establish and manage connections.
- The transport layer is responsible for multiplexing, which allows multiple applications to share the same connection.
Connection-Oriented and Connectionless Protocols
- Connectionless protocols, such as UDP, do not establish a dedicated connection between devices before transmitting data.
- UDP is a connectionless and unreliable protocol at the transport layer.
- Connection-oriented protocols, such as TCP, establish a dedicated connection before transmitting data.
- The feature unique to connection-oriented protocols is establishing a dedicated connection before transmitting data.
- The feature unique to UDP is that it is connectionless and does not establish a dedicated connection.
Protocol Features
- The feature NOT available in both UDP and TCP is establishing a dedicated connection (unique to TCP).
- Multiplexing is a feature provided by the transport layer to allow multiple applications to share the same connection.
