Below steps will show configuration to set static IP address in Cent-OS machine. Network configuration files are under "/etc/sysconfig/network-scripts". We can open the file with editor like nano, vi, vim etc... Here I will...
Hi friends,How to access Virtual machine in Oracle VM VirtualBox from host computer to?
If you have a VM installed in virtual box, of your host system and want to access it from your host system. If your system is connected to a switch you can set network attached option as bridge and can access...
Imagine u have One Ethernet point came in your room and you want to connect two device one your laptop and other one is your desktop.Now what will you do?
You can purchase a switch or a hub and connect your devices with it, Or You May pull a new wire for the your second device.But both the options...
In this post we will know about network protocols organized by OSI model.
This is list of network protocols, classified by Open Systems Interconnection (OSI) model layers.
OSI model
Layer 1 (Physical Layer)
>> Telephone network modems- V.92>> IRDA physical layer>>...
The
most basic thing to understand network is to understand about OSI model.
It is one of the most important tools which help us to know how
networking devices like router, switch, hub, computer, etc... works.To understand OSI model easily, let’s take a real life example. Many of us have posted...
InternetInternet is the world-wide network of devices accessible to anyone, or we can also say is is a network of Computers which is open for all. It itself contains a large number of intranets. It has unlimited number of users, and has a unlimited visitors traffic too. It is never ending source of...
In a daisy chain, one network node is attached to the next in a line or chain. A daisy chain topology can be linear, where the first and last two nodes are not connected, or a ring, where the first and last nodes are connected. A ring topology allows for bidirectional passing, whereas in a linear...
Hybrid networks use a combination of any two or more topologies, in such a way that the resulting network does not exhibit one of the standard topologies (e.g., bus, star, ring, etc.). For example a tree network connected to a tree network is still a tree network topology. A hybrid topology is always...
A tree topology is combination of bus topology and star topology. The nodes of bus topology are replaced with standalone star topology networks. This results in both disadvantages of bus topology and advantages of star topology.AdvantagesIt is scalable. Secondary nodes allow more devices to be connected...
The value of fully meshed networks is proportional to the exponent of the number of subscribers, assuming that communicating groups of any two endpoints, up to and including all the endpoints, is approximated by Reed's Law.Type of Mesh :-Fully connected networkPartially connected
For Other Topologies...
In a ring topology, every device has exactly two neighbors for communication purposes. All messages travel through a ring in the same direction (either "clockwise" or "anticlockwise"). A failure in any cable or device breaks the loop and can take down the entire network.To implement a ring network,...
In local area networks with a star topology, each network host is connected to a central hub with a point-to-point connection. In Star topology every node (computer workstation or any other peripheral) is connected to a central node called hub or switch. The switch is the server and the peripherals are the clients. The network does not necessarily have to resemble a star to be classified as a star...
In bus topology all device share single communication line or cable. All devices are connected to this shared line. Bus topology may have problem while more than one hosts sending data at the same time. Therefore, generally the bus topology either uses CSMA technology or set one host has Bus Master...
Point-to-point networks contains only two hosts together by any communication media.
Example:- Two mobiles sharing data through Bluetooth. Or Laptop and a Desktop are connected to each other.
For Other Topologies Click HE...
Computer network topology is the way various components of a network (like nodes, links, peripherals, etc) are arranged. Network topologies define the layout, virtual shape or structure of network, not only physically but also logically. The way in which different systems and nodes are connected and...
Based on geographical area there are many types of networks. Some of the important types Of Computer networks are :-Personal Area Networks (PAN) :A network contained within a user's home to connects his/her digital devices.
The range of PAN is 1M to 50M
Example :- connection between to cellphone...
A computer network is a set of computers or any computing device connected together for the purpose of sharing resources and data. The device which stores Data or resource are generally know as Server, the device which access those data or resources are known as Nodes or Client.
