Datacenter
People generally think of the internet as an immaterial object; however, the data that makes up the internet is stored at data servers. Businesses generally operate their own servers or rent them out from data centers giving them a chance to store their files online and make them accessible globally. An internet data center is a saving location to make it easy to access different files online.
A data center is made up of a large number of data servers that are housed within the same complex. Data servers require a working internet connection to access the files. Large data centers equipped with a huge amount of hard disk storage allow businesses that operate them to save more data. Large internet companies operate their own unique and dedicated data centers, while some data center offers their services to multiple clients.
How it works
Similar to two computers being connected in a local network, the internet server transfers information to the web browser with the help of network connections. The data stored on the internet server is divided into packets of transmission and send through a router that determines the best path through which the data can travel. The data may travel through a series of wired and wireless networks in order to reach the ISP (internet service provider) and finally to the computer.
Every time a user writes a web address in the browser, he is requesting information from the server. In turn, when you want to upload a piece of information over the internet, the process gets reversed. Over the years, data centers have evolved significantly by adopting different technologies, such as virtualization to increase IT flexibility and optimize resource utility.
