Basic Network Structure: As a programmer, we need to know how the Network works. that help them to understand the importance of Networking. how to set them in a general way to demystify and how networks really work.
so to understand this we need to understand the structure of the network.

 so today we are going to learn about what is a network and how the network works worldwide and basic network structure. we also going to take look at the structure of the network.
what is the internet, basic structure of internet
The basic network structure of the internet

Basic Network Structure

To communicate with one another man we need networks. and the internet is by which a computer can connect to another computer all over the world.

There are Tow Types of Networks

  • Local Network.
  • Global Network.

Local Network

The internet is a local network.
How we transfer the bits. the network can't work with the programming languages. they have not submitted strings whatever else.
what is local network, lan cable
Local Network
Again hardware it can only work with base two (2) numbers one(1) and not(0).
We need a LAN cable to used and transfer the bit.
LAN means Local Area Networks.

LAN Cable

It's a cable by which two computers connect and sends data to each other. the data is in sends and receive in electric charges Positive and Negative.

What is a Router

A router is a computer. it has a chipboard made of silicon. it has a firmware. it has a process as a memory as a RAM. so it can temporarily store data and also detect data.

When we connect LAN to the computer to Router. So we get Local Network.

 We have only two types of connectivity.

  • Wired
  • Wireless          

We can't have any other type. wireless need ariel technology. ariels send the bits and receive the bits. 
We need two or more computers for a network.
The network is two-way send or receive.

Global network

A global network is any communication network that connects the entire earth. when the local networks connect with each other then we give the shape to the Global Network.

Note: The first global network was established using electrical telegraphy and the global span was achieved in 1899.
