Web sockets and Ajax Comparison Table
Let’s look at the top Comparison between Web sockets and Ajax.
|Basis of Comparison Between Web Sockets vs Ajax
|Web sockets are used to define full-duplex communication between different servers and clients. It acts as a means of communication between both these sources and makes an exchange of data possible between them. Web sockets focus upon true concurrency and optimization of performance.
The distinguishing features of web sockets are as below:
|Events and Actions
When it comes to Web Socket events, there are mainly four events. They are:
– Open acts as a handshake between client and server.
|Ajax also supports events and actions. The steps that happen when an event occurs are as below:
– A XMLHttpRequest object is created.
– This object is then configured.
– The object then makes an asynchronous request to the webserver.
– The web server returns results that contain the XML document.
– The object calls the callback() function and processes the result.
– Once all this is done, the HTML DOM is updated.
|When web sockets are being used, then there are few issues that may occur. These can be Denial of Service, Man in the middle, XSS, etc. In order to overcome these web sockets, have the mechanism of a client to server masking, security toolbox, and customized browser developer tools with specific settings.
|Ajax provides security at the client-side and server-side. They use the same server-side security schemes which are used for regular web applications. A user can specify authentication, authorization and data protection as per client needs.
Both of them are useful while creating web pages. When the traditional request-response is required then, Ajax can be used, and when there is real-time communication involved and fast results are needed, then web sockets can be used. The connection, once established, will need fewer resources than Ajax requires. Hence for applications in today’s world where real-time data is given more importance, their web sockets with node js can be used for improved performances.
