If you are using the mạng internet regularly, it is highly unlikely that you have not encountered the term peer-to-peer or P2Phường. Whether it was mentioned in a news article, on TV, or in a conversation with a frikết thúc, who told you that he just downloaded the lakiểm tra version of Linux through P2P., you may have sầu stumbled upon this term. If you want to know what peer-to-peer networks are, what P2P is used for, & also see some peer-to-peer network examples, you should read this article:
What is a peer-to-peer network?
Peer-to-peer, or P2P in its abbreviated form, refers lớn computer networks using a distributed architecture. In P2Phường networks, all the computers & devices that are part of them are referred to lớn as peers, & they nói qua and exchange workloads. Each peer in a peer-to-peer network is equal khổng lồ the other peers. There are no privileged peers, and there is no primary administrator device in the center of the network.

In a way, peer-to-peer networks are the most egalitarian networks in the computer world. Each peer is equal lớn the others, and each peer has the same rights và duties as the others. Peers are both clients và servers at the same time.
In fact, every resource & each asphối that’s available in a peer-to-peer network is shared ahy vọng peers, without any central hệ thống being involved. The shared resources in a P2P.. network can be things such as processor usage, disk storage capathành phố, or network bandwidth.
What is P2Phường (peer-to-peer) used for?
The primary goal of peer-to-peer networks is to lớn share resources and help computers & devices work collaboratively, provide specific services, or exexinh tươi specific tasks. As mentioned earlier, P2P is used to mô tả all kinds of computing resources such as processing power, network bandwidth, or disk storage space. However, the most common use case for peer-to-peer networks is the sharing of files on the mạng internet. Peer-to-peer networks are ikhuyễn mãi giảm giá for tệp tin sharing because they allow the computers connected lớn them khổng lồ receive sầu files & send files simultaneously.
Imagine this situation: you open your web browser & visit a trang web where you tải về a file. In this case, the website works as a hệ thống, and your computer acts as a client receiving the file. You can compare it khổng lồ a one-way road: the tệp tin that you tải về is a car that goes from point A (the website) lớn point B (your computer).
When you tải về the same file from a peer-to-peer network, using a BitTorrent platform as a starting point, the tải về is performed differently. The tệp tin is downloaded lớn your computer in bits và parts that come from many other computers that also connected to lớn the same P2Phường network and already have sầu that file or at least parts of it. At the same time, the file is also sent (uploaded) from your computer lớn other devices that are asking for it. This situation is similar to lớn a two-way road: the file is lượt thích multiple small cars coming lớn your PC, while also leaving to lớn others when it is requested.
Why are peer-to-peer networks useful?
P2P. networks have sầu some characteristics that make them useful:It’s hard khổng lồ take them down. Even if one of the peers is shut down, the others are still operating & communicating. For a P2P.. (peer-to-peer) network to stop working, you have sầu lớn cthất bại down all its peers.Peer-to-peer networks are incredibly scalable. Adding new peers is easy as you don’t need lớn vì any central configuration on a central hệ thống.When it comes to file-sharing, the larger a peer-to-peer network is, the faster it is. Having the same tệp tin stored on many of the peers in a P2P network means that when someone needs to tải về it, the tệp tin is downloaded from multiple locations simultaneously.
P2P. (peer-to-peer) network examples
We all use peer-to-peer networks khổng lồ connect computers và devices without the need lớn configure a VPS. Having khổng lồ create a VPS for everything is expensive sầu và difficult to lớn manage, so in some situations, it’s easier và more affordable lớn use P2P.. networks. Here are some examples of common use cases for peer-to-peer networks:
P2P. networks are one of the most affordable methods of distributing content because they use the bandwidth of peers, not the bandwidth of the content’s creator.
The history of P2P (peer-to-peer) networks
The precursor of peer-to-peer networks appears to lớn be USENET, which was developed in 1979. It was a system that allowed users to read and post messages/news. It was a network system similar lớn the online forums today, but with the difference that USENET did not rely on a central server or administrator. USENET copied the same message/news to lớn all the servers found in the network. Similarly, peer-to-peer networks distribute và use all the resources available to lớn them.
