What is Proxy Server? Working, Benefits & Limitations - Proxy Server Explained

Proxy Server Proxy Server is server which retrieves data on the internet on the behalf of a user. A proxy server is an intermediate server that acts as a gateway between a client (such as a web browser) and another server (such as a website or another web server). The client sends a request to the proxy server, and the proxy server forwards the request to the destination server on behalf of the client. The response from the destination server is sent back to the proxy server, which then sends it to the client. There are several reasons why someone might use a proxy server. One common reason is to improve privacy and security. When a client connects to a website through a proxy server, the website only sees the IP address of the proxy server, not the client's IP address. This can help to protect the client's identity and location. Additionally, some proxy servers can encrypt the data that is sent between the client and the proxy server, which can further improve security. A...

What is Peer-to-Peer Network Model/Architecture? Advantages & Disadvantages

By
Image
 Peer to Peer Network Model A peer-to-peer (P2P) network model is a type of network architecture in which multiple computers (known as peers) are connected to each other without a central server or a hierarchy of clients and servers. In a peer-to-peer network, each computer has equal status and can both receive and send data directly to other computers. This means that every computer in the network can act as both a client and a server, and can share resources such as files, storage space, or processing power. Peer-to-peer networks are often used for file sharing, online gaming, and communication applications such as Skype or Zoom. They are generally more decentralized and resilient than traditional client-server networks, as they can continue to function even if some computers in the network go offline.
