For an easy introduction, lets look at its classification in terms of physical size.
You will often hear the following.
It is an intermediary between LAN and WAN.
An easily familiar example is the Internet.
online grid Devices and Terms
There are various online grid devices available, and many terminologies used.
Lets find about them the following.
Router
A router is used to connect different networks together.
I.e., for two or more LANs to be interconnected, you need a router.
It is responsible for the path determination of sent data.
Switch
The switch is responsible for connecting the computers together.
The switch is a major backbone of LANs.
As it provides an avenue for different computers to be interconnected.
This unit is known to operate at layer 2 of the OSI model standard of communication.
Hence it is a layer two gadget.
The switch is an improved form of a bridge.
Wireless Router
You might have in your home.
A wireless router helps to connect multiple devices without wire.
Access point
An access point is used in place of a switch in wireless networking.
It consists of seven layers.
The hub is known as a layer one gadget (on the OSI model), likewise the repeater.
Ethernet
Ethernet to the cabling and ports system involved in networking.
The most common of which is the RJ45 connector.
IP address
IP means Internet Protocol.
IPv4 is the most commonly used.
It was developed when the challenges of increasing IP address depletion had to be met.
It is written in the form 2031:0000:130F:0000:0000:09C0:876A:130B.
It contains both numbers and alphabets.

Every computer, switch, or router has a MAC address that is unique to itself.
This is a source of unique identity to electronic devices for easy recognition.
It is as unique as the fingerprint of human beings.
You may use aDNS record lookupto find out the resolving IP address.
This function is carried out by a router (only when it is configured to do so).
Physically its one web link, but logically they are different networks.
This is done by a switch (only when configured to do so).
wireless networking, which involves the use of Wi-Fi-enabled computers, access points, wireless routers, etc.
