The OSI model is divided into two layers: upper layers and lower layers. The upper layer of the OSI model mainly deals with the application related issues, and they are implemented only in the software. The application layer is closest to the end user. Both the end user and the application...
Wireless Bridge: - This Bridge connects with another Bridge without using wires. It uses radio signals for connectivity. In networking models such as the OSI layers model and TCP/IP model, the functionalities of Bridges are defined in the physical layer and data link layer. Just like a Hub, ...
Computer networking enables devices and endpoints to be connected to each other on a local area network (LAN) or to a larger network, such as the internet or a private wide area network (WAN). This is an essential function for service providers, businesses and consumers worldwide to share r...
Computer Network | Router: In this tutorial, we will learn what is a router, components of a router in networking? By Mahima Rao Last updated : April 26, 2023 What is a Computer Network Router?A router is a device used in networking to connect two or more packet-switched networks or...
The different types of media, topology, and transmission modes used for connecting the various types of nodes in the network have also been explained here. We have also seen how computer networks are used for intra-building networking, inter-city networking, and world wide web i.e. internet....
Even professionals working in the networking and security domain will find this book as an invaluable reference material. The strength of this book is its complete coverage of various layers of network layers from a security point of view."―Professor Tony Thomas, Ph.D., Indian Institute of ...
Section 2.1 demonstrated how computer system designers use layers to implement more elaborate versions of the three fundamental abstractions, and Section 2.2 explained how names are used to connect system components. Designers also use layers and names in many other ways in computer systems. Figure 2....

Packet Transmission across the Internet. ...
Figure 1.3 shows that these layers of software are organized primarily in a hierarchical fashion, with applications being the outermost ring and a variety of systems software sitting between the hardware and the application software.There are many types of systems software, but two types of systems...
New design contributions on all protocol layers except the Physical Layer, considering all types of networks mentioned above and their performance evaluation; novel protocols, methods and algorithms related to, e.g., medium access control, error control, routing, resource discovery, multicasting, conges...
