In what way is instant messaging a hybrid of client-server and P2P architecture?

In what way is instant messaging a hybrid of client-server and P2P architecture?

Client-server and P2P are 2 common architectures for network applications. Another application that users hybrid architecture is instant messaging. In instant messaging, the chatting between two users is typically P2P; that is, the text sent between the two users does not pass through an always-on, intermediate server.

What is hybrid of client-server?

Abstract. The HCSA (Hybrid Client-Server Architecture), a flexible system layout that combines the advantages of the traditional Client-Server Architecture (CSA) with those of the Shared Disk Architecture (SDA), is introduced.

Is WhatsApp client-server or peer to peer network?

1 Answer. WhatsApp or most of the other messaging apps rarely work on a peer-to-peer basis. So it wouldn’t open a connection (from your device) to each of your friends’ devices. Instead, your device connects to their server.

Why do protocols such as HTTP FTP and SMTP run on top of TCP rather than on UDP what is meant by a handshaking protocol?

Why do HTTP, FTP, SMTP, and POP3 run on top of TCP rather than on UDP? The applications associated with those protocols require that all application data be received in the correct order and without gaps. TCP provides this service whereas UDP does not.

What are the difference between peer-to-peer and client server?

The main difference between peer to peer and client server network is that in peer to peer network, each node can request for services and provide services while in client server network, the client nodes requests for services and server node responds with services. The devices in a network communicate with each other.

What are characteristics of client server architecture?

Characteristics of Client Server Computing The client sends a request to the server and the server responds with the desired information. The client and server should follow a common communication protocol so they can easily interact with each other.

What is hybrid of client-server and P2P?

new hybrid architecture that is called P2PWeb, between the. centralized Client/Server and the non-centralized P2P. architectures for content delivery over the Internet. This. architecture helps to reduce the load over the server in order to.

What are hybrid network explain?

A hybrid network is any computer network that uses more than one type of connecting technology or topology. For example, a home network that uses both Wi-Fi and Ethernet cables to connect computers is a hybrid.

What is a P2P server?

In peer-to-peer (P2P) networking, a group of computers are linked together with equal permissions and responsibilities for processing data. Unlike traditional client-server networking, no devices in a P2P network are designated solely to serve or to receive data.

What is a P2P used for?

The primary goal of peer-to-peer networks is to share resources and help computers and devices work collaboratively, provide specific services, or execute specific tasks. As mentioned earlier, P2P is used to share all kinds of computing resources such as processing power, network bandwidth, or disk storage space.

Why FTP is called an out of band protocol?

FTP sends its control information, which includes user identification, password, and put/get commands, on one connection, and sends data files on a separate parallel connection. Because it uses a separate connection for the control information, FTP uses out-of-band control.

Why is SMTP used instead of HTTP?

SMTP and HTTP are both network layer protocols that are used to transfer information between hosts. SMTP is used to transfer emails between mail servers, while HTTP is used to transfer data from a web server to a web client.

How is instant messaging with a centralized index a hybrid?

In what way is instant messaging with a centralized index a hybrid of client- server and P2P architectures? It is a hybrid of client server and P2P architectures: a) There is a centralized component (the index) like in the case of a client server system.

Which is an example of a pure P2P system?

is centralized. Examples of file-sharing pure P2P systems are Gnutella and Freenet, where every node is a “servent” (both a client and a server), and can equally communicate with any other connected node.

Who are the client and server in P2P?

As stated in the text, all communication sessions have a client side and a server side. In a P2P file-sharing application, the peer that is receiving a file is typically the client and the peer that is sending the file is typically the server. What information is used by a process running on one host to identify a process running on another host?

How is metadata uploaded in a hybrid P2P system?

In current hybrid P2P systems, when a user logs on, metadata on her entire library is uploaded to the server and added to the index. Similarly, when she logs off, all of her library information is removed from the index. At any given time, only the libraries of connected, or active, users are in the index.
