该层的主要功能:转换,压缩和加密。 工作在表示层的加密协议最常用的是SSL(Secure Sockets Layer)。加密协议并不一定需要工作在表示层,如IPSec(Internet Protocol Security,因特网协议安全)就工作在第三层网络层中。 第五层——会话层(Session) 可以把“会话”理解为两个应用程序进程之间的逻辑连接,两个应用程序通过...

The physical layer in OSI Model is the lowest layer. It includes physical equipment, such as switches and cables, that is required in the process of data transfer. The physical layer transfers unstructured, raw data bits, between the physical layers of the sending and the receiving device, eit...
The OSI model includes seven distinct layers. The application layer (layer 7), the presentation layer (layer 6) and the session layer (layer 5) comprise the software layers of an OSI, where all transmissions to and from software apps (including operating systems and utilities, such as web br...
NICs, or network interface cards, are a hardware component in this layer. They are typically in the form of circuit boards, which provide Internet-capable devices like computers with dedicated, full-time network connections. Receivers and transmitters are also crucial to first layer of the OSI mo...
SCTP is another connection-oriented protocol in Transport Layer. It aims to transmit data segments between endpoints alongside providing a full-duplex association. Understanding transport layer functions Layer 4 - the transport layer - is essential to computer networking. But specifically, how does the...

OSI protocols are used to form the neighbor relationship between routers (routers still establish ES/IS adjacencies and use IS-IS hello packets). Therefore, a NET address is required for SPF calculations (using Dijkstra's algorithm) and Layer 2 forwarding. The NET address is used to identify...
at which point the recipient’s device receives the bit stream and the email data traverses the same layers in reverse. At the end of the process, the email data lands in the application layer of the recipient’s device where it’s delivered, in human-readable form, to the recipient’s...
