TOPOLOGY OF NETWORK

What is the Topology of Network ?
A network topology is the arrangement of a network, including its nodes and connecting lines. There are two ways of defining network geometry: the physical topology and the logical (or signal) topology.

What are the Type Topology of Network ?
  • BUS
  • RING
  • STAR
  • MESH
  • TREE
What is the Bus Topology Network ?

Alternatively referred to as a line topology, a bus topology is a network setup in which each computer and network device are connected to a single cable or backbone.

 What is the Ring Topology ?
  
The ring topology is actually a logical ring, meaning that the data travels in circular fashion from one computer to another on the network.

What is the Star Topology ? 
Alternatively referred to as a star network, star topology is one of the most common network setups. In this configuration, every node connects to a central network device, like a hub, switch, or computer. The central network device acts as a server and the peripheral devices act as clients.

What is the Mesh Topology ?
A network setup where each computer and network device is interconnected with one another, allowing for most transmissions to be distributed, even if one of the connections go down. It is a topology commonly used for wireless networks. ... A mesh topology can be a full mesh topology or a partially connected mesh topology.

What is the Tree Network Topology ? 

A tree network, or star-bus network, is a hybrid network topology in which star networks are interconnected via bus networks. Tree networks are hierarchical, and each node can have an arbitrary number of child nodes.

LOCAL AREA NETWORK

What is the Local Area Network ?

 Usually, a LAN comprise computers and peripheral devices linked to a local domain server. All network appliances can use a shared printers or disk storage. A local area network serve for many hundreds of users. Typically, LAN includes many wires and cables that demand a previously designed network diagram.

PRIVATE IP ADDRESS

PRIVATE IP ADDRESS:

What is the Private IP Address ?
A private IP address is a non-Internet facing IP Address on an internal network. Private IP addresses are provided by network devices, such as routers, using network address translation (NAT).

What Are the Private IP Address ?

Class A - From 10.0.0.0 To 10.255.255.255
Class B - From 172.16.0.0 To 172.31.255.255
Class C - From 192.168.0.0 To 192.168.255.255
