What is OSI Model: A Complete Guide to The 7 Layers of the OSI Model In thisFree Networking Training Series, we explored all aboutComputer Networking Basicsin detail. OSI Reference Model stands forOpen system interconnection reference modelwhich is used for communication in various networks. The I...
The physical layer defines how data will flow between connected devices (as simplex, half duplex or full duplex transmission). Physical topologies.The physical level specifies how network devices and nodes are situated (in bus, star or mesh topologies, for example). Standards like USB, Bluetooth ...
This sub-layer identifies the network layer protocol. On the sending computer, it encapsulates the information of the Network Layer protocol in the LLC header from which the Data Link layer receives the data packet. On the receiving computer, it checks the LLC header to get the information abou...
It is a standard model in computer networking. Supports connectionless and connection-oriented services. It offers flexibility to adapt to various types of protocols. Advantages of TCP/IP Here, are pros/benefits of using the TCP/IP model: It helps you to establish/set up a connection between ...
In order for the packet to get onto the basic networking transmission technologies of the network, it is then passed to OSI Layer 1 or the Physical Layer to complete the task. The physical layer takes the binary packet and physically encodes it onto network cabling — or places it onto the...
NICs, or network interface cards, are a hardware component in the physical 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...
The presentation layer ensures the data is prepared in a usable form for the application layer (receiving side) or for the network layer (sending side). Layer 6 is responsible for: Data translation Encryption & decryption Compression Other data preparation items ...
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...

However, within a routing domain that conforms to IS-IS, the lower-order octets of the NSAP should be structured as the ID and SEL fields shown in Figure 1 to take full advantage of IS-IS routing. End systems with addresses which do not conform may require additional manual configuration ...
