On certain occasions when Internet connection is lost then there are different possibilities of disconnection, If we want to check out our LAN (Local Area Network) then we need to perform a ping check to our local assigned IP if it responds then there is nothing wrong with the LAN connection or settings, one of the next remaining possibilities is checking that particular domain, if it does not respond then there are two possibilities, Either the ISP where the domain is hosted has suffered downtime or there is an issue with our own ISP connection. For investigating furthermore we need to perform ping check for the other domain and if it responds then there is nothing wrong with our ISP connection and the only remained possibility is that there is something wrong with the ISP of the domain hosted place. As Servers are hosted on two main platforms ‘Windows Hosting and Linux Hosting‘ I would like to share following Pingcheck procedures for both Windows and Linux.

For Windows

Start Menu >> Click Run

In Run Window type the command ‘cmd’ and hit enter key.

Command prompt window will open where you need to type the following

For checking LAN connection ”ping IP Address”

For chcking ISP connection “ping domain.com”

For Linux

Accessaries >> Terminal Window, this will open a terminal window where you need to type these command

‘ping domain.com’ or ‘ping IP address’

What is network?

A network is a collection of computers connected to each other. When the number of computers are interlinked with each other through the main server is known as network. The network allows computers to communicate with each other and share resources and information among the connected computers.

Computers on a network are sometimes called Nodes.

Computers and devices that allocate resources for a network are called Servers.

Types of Network
=============

1. Local-Area Networks (LANs) : The computers are geographically together in the same premises (that is, in the same building).

2. Wide-Area Networks (WANs) : The computers are not located in the same area, set wide apart and are connected by telephone lines or radio waves.

3. Campus-Area Networks (CANs): The computers are within a limited geographical area, such as a campus or military base.

4. Metropolitan-Area Networks (MANs): A data network designed for a town or city.

5. Home-Area Networks (HANs): A network contained within a user’s home that connects a person’s digital devices.

6. Global Area Networks (GANs): GAN is a model for supporting mobile communications across an arbitrary number of wireless LANs, satellite coverage areas, etc.

7. Virtual Private Network ( VPNs ) : A computer network in which some of the links between nodes are carried by open connections or virtual circuits in some larger network instead of through physical wires(e.g., the Internet). A VPN allows computer users to appear and edit from an IP address location other than the one which connects the actual computer to the Internet.
