Questimi 03):- Differentiate b/W XIB and NIB.(2MarkS)

XIBs are flat files rather than being a bundle. This makes it easier for SCM systems to deal with. When you compile your app, the XIB is compiled into a NIB file for inclusion in your app.

The compiled NIB that is included in the app bundle is no longer editable in Interface Builder and is much smaller than the equivalent XIB or legacy NIB file.

When browser sends request to web server, in which formats server sends back information to web server? Give 4 examples?

JS, server-side programming, and web browser, all work together. Web browser: xmlhttprequest object. Makes ajax possible. Talks to web server and get response. JS: sends request, waits for response, process response, updates web page. Web server: receives request and responds as HTML, plain text, XML, JSON. Or application server for more complicated tasks. Need web server for ajax examples. For talking to web server, we create xmlhttprequest (also called XHR in short) var newxhr = new XMLhttprequest(); again browser incompatibilities call open to specify what kind of data and where it will go can GET or POST newxhr.open(’GET’, ’shop.php?Productid=34’);
