Networking between Host Computer and VM In VirtualBox

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...

OSI Model (7 Layers of OSI Model, and How it works).

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...

Daisy Chain Topology

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 Topology

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...

Tree Topology

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...

Mesh Topology

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...

Ring Topology

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,...

Star Topology

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...

Bus Topology

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...

Network topology

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...
