computer network
so, guys, this is my 1st blog I'm not professional in writing a blog and all stuff I also not a teacher or someone with great knowledge of networking. so basically I am a 19 years old undergraduate learner who shares you the stuff about networking. The basic funda of this blog series is everyone I mean dum like I also understand the concept of networking it is a very interesting concept. I this blog I covered basic topics like what is a network, support, topology, node, and layout. so without wasting your precious time let's get started.
Now as you heard the word network what comes in your mind 1st? I know 90% of people imagine a sort of wires, big devices where wires and all jumbling stuff I also imagine that kind of stuff when I first heard it but it is correct visualization because there is plenty kind of stuff in networking. so what is a computer network? networking means a connection of devices right, so computer network means the connection of computer or devices isn't it simple? here the main definition connection of all computers to transfer data or to share data is called computer network.
so, here is the question in your mind that when we call the computer or devices are in-network? suppose there are two computers (devices) are connecting via wired or wireless when one of the computer or device transfers data or communicate to another device then it is said that these two devices are in-network. computer network supports enormous applications such as the world wide web(www), digital video, audio shared use of application and storage server, printer, fax machine and us of email and instant messaging, etc. there is a word (node) which use in networking concept so what is a node? you simply say that node is the endpoint of networks. it is attached to a network for creating, receiving or transmitting information over a communication channel. generally identify by network address there are two nodes
1.node that use network(host)
2.node that implement network(switch, routers, hub)
we will discuss that type later
now we are headed to our last topic of this blog, Network topology
Network topology:- It is a layout of interconnected nodes over a computer network. (layout of connection)
there are 6 types in topology
1. Bus Network:- All nodes are connected to a common medium along this medium means there is one medium and all computers are connected to it see above figure so you get an idea. this is used in original ETHERNET called 10Base5 and 10Base2.(10Base5 and 10Base2 are the type of ethernet cable)
2. Star Network:- All nodes are connected to a central special node. and form a star type design. this layout found in wireless LAN(local area network).
3. Ring Network:- In this network, each node is connected to the right or left neighbouring node, so that all nodes are connected to each node. by travelling left or right we can reach the destination.
commonly used in FDDI(fibre distributed data interface).
4. Mesh Network:- In mesh a node is connected to an arbitrary number of neighbouring node in such a way that the distance between two nodes for travelling is minimum. means connecting a random node ion network so that the distance between the node is minimum.
5. Fully connected network:- In this network, every node is connected to each mode of network.
6. Tree network:- Nodes are arranged in hierarchically.
I hope this has been information is informally for you and I'd like to thank you for reading. (comment if it is helpfully and also suggest the way of my writing so I can improve it.)
