These are some of the frequently asked questions in web designing w.r.t node.js

1. What do you mean by node.js?

Node.js is actually a Server side scripting language which is basically used to build expandable programs. It has got its own multiple advantages to rule over the other existing server side languages, one of such notable feature being the non-blocking I/O characteristic.

2. How node.js initially works?

Node.js language works on the v8 environment which is a virtual machine using JavaScript as the scripting language. It succeeds in achieving an elevated output using features like non-blocking I/O and also the single threaded event loop.

3. What do you understand by the term I/O w.r.t Node.js?

Generally I/O is the abbreviation used for Input/ Output, which will effectively access any and everything outside of the ongoing application. One the application is initiated; it is loaded into the memory of the machine which is running the program to get efficient and drastic outputs.

5. What are the applications of node.js?

The uses of Node.js include the following:

a) Web based applications in which it excels especially in the real-time web applications.

b) Network or server based applications

c) Distributed systems applications

d) General purpose applications

6. What are the advantages of using node.js?

a) It makes the development of expandable programs fast and easy.

b) Prominent for its speed and accuracy

c) Wide range of applicability

d) Every function is asynchronous of the other

e) Hardly does it block any program or function

7. Is node.js compatible with windows OS?

Yes it is very much usable on Windows operating system.

8. What is making node.js gain more attention from JAVA developers?

9. What are the merits and demerits of Node.js?

Merits:

a) If an application lacks a computation thorough with the CPU thorough, even then the application can be developed from top to bottom in Javascript, as much down as to the database level if in case the JSON storage object DB like MongoDB is being used by the programmer.

b) Crawlers used by Node.Js program receives a fully supported HTML response, which in turn is far better in the angle of SEO rather than using a single page based application or an app running on web sockets.

Demerits:

a) Any exhaustive CPU computation process will block the node.js responsiveness, so in that case a threaded platform would be a better choice.

b) Relational database are not very favourable when it comes to Node.js

10. What is the basic difference between Node.js and Ajax?

The difference between Node.js and Ajax (Asynchronous Javascript and XML) is that the former is a server side javascript used in the development of server software. Whereas, AJAX is a client side programming tool, which is frequently used to update the web page content without refreshing the entire page.
