Networking Tutorial

Networking Tutorial Or Networking

The network is a connection between at least two computers usually by cable, running software which allows them to communicate with one another.

Users over a network can share computer resources such as hard drives, printers, modems, CD-ROM drives, and processors.

Although most networks are more complicated than this two-computer scenario, all networks are based on the concept of sharing.

There’s actually a great work of technology involved when one computer connects to and communicates with another.

In addition, there are many types of physical connections and related software to consider.

In the following sections, we discuss some fundamental concepts behind all networks and explain what kinds of network models are appropriate for various business environments.

LAN:

Topologies

Topologies Topology is a way for arranging a number of systems such that they provide a better communication and response among each other. Bus Topology – A bus topology connects each computer to a signal …

What is Network Protocol Drivers?

What is Network Protocol Drivers? Protocol Drivers  A protocol is a set of rules that govern communications between two entities (Stations). A protocol defines what is communicated how it is communicated. The key elements of a protocol are syntax, semantics, and timing.   Syntax …

Session Management

Session Management Session Management involves establishing, maintaining and terminating connections between stations on the network in order to transfer data. A session is analogous to a telephone call. The protocol drivers on the computer wanting to communication negotiate the creation of connections. One station …

Data Gram Services

Data Gram Services A datagram service is just like a basic messaging service. Unlike the complete service that session management provides, datagram data transfer services operate more like mailing a letter. Datagram services are connectionless, no association exists …

Acknowledgement

Acknowledgment is the process used to guarantee a reliable end to end data delivery. A protocol driver at one station guarantees reliable communications by requiring an acknowledgment for every data frame received. The protocol detects and recovers from errors by …

What is Routing?

What is Routing? Routing across a WAN requires the addition of a network address field to each frame. Intermediate systems Use the network address like an area code to route the frame to the correct destination LAN. …

Network Devices & Interface Specification

Network Devices & Interface Specification NDIS provides a very flexible environment for data exchange. It defines the software Interface, called the NDIS interface, used by protocols drivers to communicate with the network adapter. Advantages of a standardize Interface 1) …

Open Data Link Interface

Open Data Link Interface The Open Datalink Interface (ODI) specification was defined to simplify driver development and to provide support for multiple protocol drivers on a single network adapter. ODI allows Novell Netware drivers to be written without …
