Create devices and software that can communicate with products from any other vendor, allowing open interoperability.The OSI model helps network device manufacturers and networking software vendors: Perform troubleshooting, by identifying which network layer is causing an issue and focusing efforts on that layer.Understand and communicate the process followed by components communicating across a network.Determine the required hardware and software to build their network.The OSI model helps users and operators of computer networks:

#LAYER STACKING SOFTWARE SERIES#

It defines the connector, the electrical cable or wireless technology connecting the devices, and is responsible for transmission of the raw data, which is simply a series of 0s and 1s, while taking care of bit rate control. The physical layer is responsible for the physical cable or wireless connection between network nodes.

This layer is composed of two parts-Logical Link Control (LLC), which identifies network protocols, performs error checking and synchronizes frames, and Media Access Control (MAC) which uses MAC addresses to connect devices and define permissions to transmit and receive data. It breaks up packets into frames and sends them from source to destination. The data link layer establishes and terminates a connection between two physically-connected nodes on a network. The network layer uses network addresses (typically Internet Protocol addresses) to route packets to a destination node. The other is routing packets by discovering the best path across a physical network. One is breaking up segments into network packets, and reassembling the packets on the receiving end. The network layer has two main functions. The transport layer carries out flow control, sending data at a rate that matches the connection speed of the receiving device, and error control, checking if data was received incorrectly and if not, requesting it again. It is responsible for reassembling the segments on the receiving end, turning it back into data that can be used by the session layer. The transport layer takes data transferred in the session layer and breaks it into “segments” on the transmitting end. The session layer can also set checkpoints during a data transfer-if the session is interrupted, devices can resume data transfer from the last checkpoint. It is responsible for opening sessions, ensuring they remain open and functional while data is being transferred, and closing them when communication ends. The session layer creates communication channels, called sessions, between devices.

The presentation layer takes any data transmitted by the application layer and prepares it for transmission over the session layer. It defines how two devices should encode, encrypt, and compress data so it is received correctly on the other end.

The presentation layer prepares data for the application layer. A few examples of application layer protocols are the Hypertext Transfer Protocol (HTTP), File Transfer Protocol (FTP), Post Office Protocol (POP), Simple Mail Transfer Protocol (SMTP), and Domain Name System (DNS). It provides protocols that allow software to send and receive information and present meaningful data to users. The application layer is used by end-user software such as web browsers and email clients. We’ll describe OSI layers “top down” from the application layer that directly serves the end user, down to the physical layer.

#LAYER STACKING SOFTWARE ISO#

OSI was introduced in 1983 by representatives of the major computer and telecom companies, and was adopted by ISO as an international standard in 1984. However, the OSI 7-layer model is still widely used, as it helps visualize and communicate how networks operate, and helps isolate and troubleshoot networking problems. The modern Internet is not based on OSI, but on the simpler TCP/IP model. It was the first standard model for network communications, adopted by all major computer and telecommunication companies in the early 1980s The Open Systems Interconnection (OSI) model describes seven layers that computer systems use to communicate over a network.
