Data communication and networking topics
Network computing is a generic term in computing which refers to computers or nodes working together over a network.
The two basic models of computing are: 1- centralized computing:- where computing is done at a central location, using terminals that are attached to a central computer..
What is a computer network model?
A Computer Network model is made up of three primary components: A sender, A recipient, and A carrier.
It offers modularity and explicit interfaces, allowing subsystems to communicate.
It maintains layer independence by offering services from a lower to a higher layer without specifying how they are implemented..
What is computer network working?
Computer networking refers to interconnected computing devices that can exchange data and share resources with each other.
These networked devices use a system of rules, called communications protocols, to transmit information over physical or wireless technologies..
What is the purpose of a network model?
In computing, the network model is a database model conceived as a flexible way of representing objects and their relationships.
Its distinguishing feature is that the schema, viewed as a graph in which object types are nodes and relationship types are arcs, is not restricted to being a hierarchy or lattice..
What is the working model of the Internet?
Fundamentally, the Internet model is that independent networks connect to one another and, all together, provide the global Internet.
The independent networks may be enterprises with business services and employees connected to them, they may be cloud service providers or residential Internet service providers..
- Network computing is a generic term in computing which refers to computers or nodes working together over a network.
The two basic models of computing are: 1- centralized computing:- where computing is done at a central location, using terminals that are attached to a central computer. - TCP/IP is a functional model designed to solve specific communication problems, and which is based on specific, standard protocols.
OSI is a generic, protocol-independent model intended to describe all forms of network communication. - Three types of network models and their associated distributions: (a) random network, (b) scale-free network, and (c) hierarchical network.
