What is Peer-to-Peer (P2P)?

1. Definition

Peer-to-peer (P2P) technology allows computers to communicate with each other directly, without relying on a central server. In a P2P network, each computer acts as both a client and a server, connecting to multiple other peers in the network.

2. Key Features

Decentralized: P2P networks do not have a central authority to control the network or store data. Instead, data is distributed across all computers in the network.
Resilient: P2P networks are more resilient to failures than centralized systems. If one computer goes offline, the network can continue to function by connecting other peers.
Scalable: P2P networks can grow and expand by adding more peers to the network.

3. Applications

P2P technology has a wide range of applications, including:

File sharing: BitTorrent and other file-sharing applications use P2P technology to distribute large files across the internet.
Cryptocurrency mining: Cryptocurrencies like Bitcoin can be mined using P2P networks, where miners solve complex mathematical problems to generate new blocks.
Distributed computing: P2P networks can be used for distributed computing projects that require large amounts of processing power, such as weather prediction models.

4. Advantages

Improved privacy and security: P2P networks can offer improved privacy as no central server stores user data.
Reduced costs: P2P networks do not require expensive infrastructure, making them cost-effective for applications that need to distribute data widely.
Increased flexibility: P2P networks can be adapted to a variety of different applications, making them versatile and customizable.

5. Limitations

Network speed can be inconsistent: P2P networks rely on the speed of individual computers, which can lead to variations in network performance.
Can be vulnerable to malicious attacks: P2P networks can be targeted by viruses and other malware that can spread through the network.
Requires a stable internet connection: P2P networks require a stable internet connection to function effectively.
