Network Basics: The 7 Layers of the OSI Model In the 1980s, networking was in its infancy. Engineers needed a way to visualize the different elements of a networking system. The computing world urgently required a standard language to communicate across companies, business sectors and even ...

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 Open Systems Interconnection (OSI) model—also called the OSI reference model—is a conceptual model that divides network communication and interoperability into seven abstract layers. It provides a standardized model that enables different applications, computer systems and networks to communicate. The...
What is TCP/IP Model? TCP/IP helps you to determine how a specific computer should be connected to the internet and how you can transmit data between them. It helps you to create a virtual network when multiple computer networks are connected together. TCP/IP stands for Transmission Control ...
The Open Systems Interconnection model (OSI model) is a product of the Open Systems Interconnection effort at the International Organization for Standardization. It is a way of sub-dividing a communications system into smaller parts called layers. A layer is a collection of co...
Once the packet reaches the destination server, the whole process reverses and the packet travels back up the layers of the OSI model. This process happens constantly as your computer communicates with other remote servers on the Internet.
The internet control message protocol (ICMP) model recognizes just four types of functionality (not seven). And that model doesn’t list those functions in a hierarchical form. Instead, the functions connect and intertwine based on the goal of the specific type of network communication. ...
The Physical Layer is the first layer of the OSI model. This layer specifies the standards for devices, media, and technologies that are used in moving the data across the network such as:- Type of cable used in connecting the devices ...
When troubleshooting network problems, the physical layer is typically the first place to start. The physical layer is the lowest layer in theOpen Systems Interconnect (OSI) modelofcomputer networking. In this article, learn how the physical layer of the OSI model is concerned with the physical ...
