The session layer is Layer 5 of theOSIcommunications model. It is the long-lived logical connection that persists between endpoints over time. A single session is all the back-and-forth communication between two endpoints. It helps a protocol to be more consistent and reliable. The TCP/IP pro...
The physical layer is the layer closest to the physical connection between devices. This layer covers a variety of devices and mediums, among them cabling, connectors, receivers, transceivers and repeaters. The physical layer doesn't deal with the physical medium, but it specifies the properties ...
That is, this plate extends from the west coast of North America to the middle of the Atlantic Ocean. 从“The top layer of the earth is called the earth’s crust”,可以推断出答案。反馈 收藏
Layer 7 is the layer of the OSI Model just beneath the surface of user interfaces, and on top of the other 6 layers of the model. In this layer, data is presented in a form that user-facing applications can use. DDoS attacks often take place on layer 7. ...
The session layer makes sure the session is open for a long enough period of time for all the necessary data to be sent through. The session layer then closes the session to prevent expending unnecessary resources. Also, it synchronizes the data transfer. If a large amount of data is ...
seven layers to perform specific functions while relying on the services provided by the layer immediately below it. When data is transmitted from one device to another, it passes through all seven layers at the sender and then traverses all seven layers at the receiver. Here's how it wo...
5. Session Layer The Session Layer manages and controls the connections between computers. It establishes, maintains, and terminates connections, ensuring that data exchanges occur efficiently and in an organized manner. The layer is responsible for session checkpointing and recovery, which allows sessio...
What is Transport Layer Security (TLS)? Transport Layer Security, or TLS, is a widely adopted security protocol designed to facilitate privacy and data security for communications over the Internet. A primary use case of TLS is encrypting the communication between web applications and servers, such...
The OSI (Open System Interconnect) model has seven layers, each of which is assigned a set of functions. Layer 4, or the transport layer, is the layer used in end-to-end communication across a network. It's crucial to the transmission of data across network connections. In this article,...
Layer refers to a sheet or level of material, often part of a larger structure, while a coating is a thin layer applied to a surface for protection or decoration.
