Networking Terminology

This page on Networking terminology describes terms related to networking domain. It covers OSI, TCPIP, ARP, RARP, Router, Hub, Switch, Ethernet, Gateway, MAC, PHY, IP address, Ethernet address, LAN, WAN, Internet, IoT, M2M etc.

Networking Terms Basic description RF Wireless World Reference
OSI Open System Interconnection OSI basics
TCPIP Transmission Control Protocol/Internet Protocol TCPIP comparison with OSI stack
ARP Address Resolution Protocol, maps ip address to the ethernet address ARP vs RARP
ARP protocol inside
RARP Reverse Address Resolution Protocol, maps ethernet address to the ip address Refer link above
Router The networking device used to route the packet to appropriate destination based on destination ip address embedded within IP Header. What is Router
Hub Connects more than one ethernet segments Ethernet Hub
Switch Switch works similar to router with intelligence built in to route the ethernet packet to appropriate sub networks. Ethernet Switch
Ethernet The medium built in to support higher data rate of transmission such as 10Mbps and 100Mbps. It is referred as ethernet cable. What is Ethernet
Gateway It connects two networks of different protocols. networking Gateway
MAC It stands for Medium Access Control Protocol. It lies at layer-2 of the OSI stack. It takes care of segmentation, assembly as well as flow control and error control(using ARQ protocol). WiMAX MAC protocol
PHY It stands for Physical Layer. It lies at layer-1 of the OSI stack. It takes care of functions such as modulation, syntax conversion, FEC, scrambling and so on. Wireless PHY
IP address The logical address used to define the device over the internet as well as intranet. It can be 32 bit or 128 bit in size as per IPV4 or IPV6 respectively. What is IP Address
Ethernet address The physical address used to identify the device connected over ethernet. It is a 48 bit address. What is Ethernet Address
LAN Local Area Network LAN vs WAN vs MAN
WAN Wide Area Network Refer above link
Internet Interconnection of computers to form larger network. Internet vs Intranet
IoT Internet of Things, the technology by which various devices can communicate to one another using ip address. IoT basics
M2M Machine to Machine communication M2M
