A common set of communications rules,known as network protocols.

All the computers on any given network must use the same network protocol or protocol suite to communicate with each other.



The three major network protocols are TCP/IP,IPX/SPX and NetBEUI.

Network protocols are not tied to particular hardware,they r software and can be installed to or removed from any computer on the network at any time as necessary.



TCP/IP has evolved to become the dominant protocol for large and small networks alike.It is the internet standard protocol.



TCP/IP best used for most windows-based networks.

IPX/SPX best used for Novell 4.x and earlier networks

NetBEUI for older Windows for workgroups

Dear Friend



What is a Network Protocol?

Network protocols defines a language of rules and conventions for communication between network devices.



What Is Packet Switching?

Packet switching is a method used by network protocols including IP and Frame Relay to deliver data across a computer network connection in individually delivered small pieces.



PPPoE

PPPoE (Point-to-Point Protocol over Ethernet) is a network protocol sometimes used by broadband modems for connecting to DSL Internet service.



ARP - Address Resolution Protocol

ARP converts an IP address to its corresponding physical network address. ARP is a low-level protocol usually implemented in the device drivers of network operating systems. ARP is most commonly utilized on Ethernet networks.



HTTP - HyperText Transfer Protocol

The Hypertext Transfer Protocol - HTTP - provides a standard for Web browsers and servers to communicate. HTTP is an application layer network protocol built on top of TCP.



ATM Protocol - Asynchronous Transfer Mode Networking

ATM is a high-speed networking standard designed to support both voice and data communications. ATM operates at the data link layer (OSI Layer 2) over either fiber or twisted-pair cable.



Spanning Tree Protocol

The Spanning Tree Protocol implements a standard algorithm to prevent redundant transmission of data along intermediate hops between a source and destination host.



NTP - Network Time Protocol

Network Time Protocol is a server based system to synchronize time of day clocks computer across the Internet.



SOCKS

SOCKS is an Internet protocol designed to allow clients to communicate with proxy servers (or VPN servers) through network firewalls.



UWB

Ultra-wideband - UWB - is a communication method used in wireless networking to achieve high bandwidth connections with low power utilization. Originally designed for use in commercial radar systems, UWB technology is gradually being adopted in consumer electronics and wireless personal area networks (PANs).



Frame Relay

Frame relay is a network protocol designed for use on Wide Area Networks (WANs). Frame relay works over fiber optic or ISDN lines.



FireWire

FireWire (IEEE 1394) is a high-speed serial networking standard for connecting a computer to a nearby peripheral device such as a digital video camera.



X.25

X.25 is a standard suite of protocols used for packet switching and delivery between networks. The X.25 protocols works at the physical, data link, and network layers (Layers 1 through 3) of the OSI model.



SNMP - Simple Network Management Protocol

SNMP is a standard TCP/IP protocol for network management including the monitoring and control of network devices.



H.323

H.323 is a protocol standard for multimedia communications. H.323 was designed to support real-time transfer of audio and video data over packet networks.



SS7 - Signaling System 7

The SS7 protocol provides mechanisms for exchanging special-purpose messages on public telephone networks.



SCTP - Stream Control Transmission Protocol

SCTP is an alternative transport protocol to TCP and UDP. Some higher level network protocols like SIP and SS7 use SCTP.



Ethereal Network Protocol Analyzer

Ethereal is a high quality utility program commonly used by students, researchers and some companies to monitor network traffic.



"Internet Core Protocols - The Definitive Guide"

This book features in-depth technical background on fundamental network protocols such as TCP, ICMP and ARP.
