HOW DOES DATA TRAVELS THROUGH NETWORKS?

The internet has become an integral part of our daily lives, and the way we communicate, work, and access information has changed drastically over the past few decades. But have you ever wondered how data travels through the internet? In this article, we will take a deep dive into the complex system that makes it possible for us to send and receive data across the globe. The journey of data through the internet begins at the source, where it is created or transmitted. This could be a computer, smartphone, or any other device that can send data over the internet. When you type an email, upload a file, or send a message, the data is generated at this end. Once the data is generated, it reaches the network interface of the sending device. This could be an Ethernet port, Wi-Fi antenna, or any other device that enables communication over the internet. The network interface converts the digital data into analog signals, which can travel through the physical medium (cable) to reach the next device. The data now travels through a network of routers and switches, which direct it towards its destination. 

USING CELLULAR NETWORK

A cellular network or mobile network is a telecommunications network where the link to and from end nodes is wireless and the network is distributed over land areas called cells, each served by at least one fixed-location transceiver (such as a base station). These base stations provide the cell with the network coverage which can be used for transmission of voice, data, and other types of content. A cell typically uses a different set of frequencies from neighboring cells, to avoid interference and provide guaranteed service quality within each cell.

When joined together, these cells provide radio coverage over a wide geographic area. This enables numerous portable transceivers (e.g., mobile phones, tablets and laptops equipped with mobile broadband modems, pagers, etc.) to communicate with each other and with fixed transceivers and telephones anywhere in the network, via base stations, even if some of the transceivers are moving through more than one cell during transmission.
