Why is OSI model inefficient?
OSI models were never taken into consideration because of competition TCP/IP protocols that were already used widely. This is due to second reason that OSI model and its protocols are flawed that means both of them have fundamental weakness or imperfection or defect in character or performance or design, etc.
What is OSI model tell about its layers and their working?
OSI stands for Open System Interconnection is a reference model that describes how information from a software application in one computer moves through a physical medium to the software application in another computer. OSI consists of seven layers, and each layer performs a particular network function.
What are the main benefits of layered Open Systems Interconnection model?
The advantages of the OSI model are It distinctly separates services, interfaces, and protocols. Hence, it is flexible in nature. Protocols in each layer can be replaced very conveniently depending upon the nature of the network. It supports both connection-oriented services and connectionless services.
What protocol works on all layers of OSI?
Protocols supported at various levels
| Layer | Name | Protocols |
|---|---|---|
| Layer 6 | Presentation | MPEG, ASCH, SSL, TLS |
| Layer 5 | Session | NetBIOS, SAP |
| Layer 4 | Transport | TCP, UDP |
| Layer 3 | Network | IPV5, IPV6, ICMP, IPSEC, ARP, MPLS. |
Which OSI model layers typically correspond to the network architecture?
Which OSI model layers typically correspond to the network architecture? Session, Transport, Network, and Data Link layers (Layers 2-5).
What is layered protocol?
A protocol is a set of rules and conventions that describe how information is to be exchanged between two entities. A set of protocols layered in this way is called a protocol stack. A layer can have more than one protocol defined for it.
