What is P2P.. (peer-to-peer) used for?

The primary goal of peer-to-peer networks is to mô tả resources và help computers & devices work collaboratively, provide specific services, or exedễ thương specific tasks. As mentioned earlier, P2P.. is used to lớn nội dung all kinds of computing resources such as processing power, network bandwidth, or disk storage space. However, the most comtháng use case for peer-to-peer networks is the sharing of files on the mạng internet.

This situation is similar khổng lồ a two-way road: the file is lượt thích multiple small cars coming to your PC, while also leaving to lớn others when it is requested.

It’s hard lớn take them down. Even if one of the peers is shut down, the others are still operating và communicating. For a P2P (peer-to-peer) network to lớn stop working, you have to lớn cchiến bại down all its peers.Peer-to-peer networks are incredibly scalable. Adding new peers is easy as you don’t need to lớn do any central configuration on a central VPS.When it comes to file-sharing, the larger a peer-to-peer network is, the faster it is. Having the same file stored on many of the peers in a P2P network means that when someone needs khổng lồ download it, the tệp tin is downloaded from multiple locations simultaneously.

P2P (peer-to-peer) network examples

We all use peer-to-peer networks lớn connect computers & devices without the need to lớn configure a hệ thống. Having lớn create a hệ thống for everything is expensive and difficult khổng lồ manage, so in some situations, it’s easier and more affordable khổng lồ use P2P. networks.

It was a network system similar khổng lồ the online forums today, but with the difference that USENET did not rely on a central VPS or administrator. USENET copied the same message/news to all the servers found in the network. Similarly, peer-to-peer networks distribute and use all the resources available to them.
