What is the difference between sockets and WebSockets?

WebSockets typically run from browsers connecting to Application Server over a protocol similar to HTTP that runs over TCP/IP. So they are primarily for Web Applications that require a permanent connection to its server. On the other hand, plain sockets are more powerful and generic.

What is difference between socket and HTTP connection?

With sockets you go on the level lower and actually control the connection and send/receive raw bytes. HTTP connection is a protocol that runs on a socket. HTTP connection is a higher-level abstraction of a network connection.

Which is better cookie or session?

Cookies store it directly on the client. Sessions use a cookie as a key of sorts, to associate with the data that is stored on the server side. It is preferred to use sessions because the actual values are hidden from the client, and you control when the data expires and becomes invalid.

What is the difference between cookies and session in what circumstance should someone use cookies or session Support your answer with practical examples?

Cookies and Sessions are used to store information. Cookies are only stored on the client-side machine, while sessions get stored on the client as well as a server. A session creates a file in a temporary directory on the server where registered session variables and their values are stored.

Are WebSockets slower than sockets?

WebSockets performs quite well, with an average round trip time of about 20 microseconds (0.02 milliseconds), but straight up TCP still beats it handily, with an average round trip time of about 2 microseconds (0.002 milliseconds), an order of magnitude less.

What is a WebSocket connection?

WebSocket is a communications protocol for a persistent, bi-directional, full duplex TCP connection from a user’s web browser to a server. A WebSocket connection is initiated by sending a WebSocket handshake request from a browser’s HTTP connection to a server to upgrade the connection.

What exactly is a socket?

Definition: A socket is one endpoint of a two-way communication link between two programs running on the network. A socket is bound to a port number so that the TCP layer can identify the application that data is destined to be sent to. Every TCP connection can be uniquely identified by its two endpoints.

What is a port socket?

A socket port is one endpoint in a statement flow in the middle of two programs running over a network, also it is maintaining and allow communication between two different processes on the same or different machines. socket address is the combination of an IP address and a port number.

What is the difference between a session and a cookie?

The main difference between a session and a cookie is that session data is stored on the server, whereas cookies store data in the visitor’s browser. Sessions are more secure than cookies as it is stored in server. Cookie can be turned off from browser. Data stored in cookie can be stored for months or years,…

Where are session cookies stored in PHP?

If you’re using PHP you can check the session.save_path location and actually “see sessions”. They are either files on the server filesystem or backed in a database. The main difference between a session and a cookie is that session data is stored on the server, whereas cookies store data in the visitor’s browser.

Is cookie value available on server side or client side?

So cookie value is available on both client-side as well as on server side but there are some more differences between these two like the following: Local Storage Value can be shared between multiple windows of the same browser easily.

What is the difference between a session and a connection?

The terms session and connection are used to refer a communication between client and a server or two end points and they are used in same context. If you look at pure theory then: The bidirectional flow between client and server is a connection. Client Src IP (1.1.1.1) Client Port (12345) TCP ———> Server Src IP (2.2.2.2) Server Port (80)
