What is REAL? Is there any VIRTUAL language. Any piece of code that perform some action is a language. How meaningful the action is is a different issue. So binary is as programming language as C, jav...

No, it is not a real programming language. it is just a markup language.

Revoking read basically takes out all permissions on that file.
In simplest term we cannot load any file (CFM or txt).

Enterprise level CF applications use separate clustering software with sticky session approach to use multiple webservers clustering. But to use coldFusion clustering for multiple instances ( can be on same server) we need to perform J2EE clustering.

ColdFusion can have client side non-coldfusion codes (Like JavaScript, Jquery). It cannot have client side coldfusion codes.

coldfusion is used mostly is serverside because of security reasons only.. But ican be used in client side too

Here we go.There are two types of structure:1. nested structure 2. Simple structure.For 1 st ,copied structure will not have the reference pointing towards the original so if you change the ...

You may use cfftp tag to access, upload and list files inside a secure ftp server.

If you already have an FTP account with a remote host, you can use the CFFTP tag to transfer files between your computer and your host right in your ColdFusion application.

We can use cfloop = "collection" attribute to loop over form and url. Form and URl comes in Structure format.

can be used to loop through URL and FORM.

Creating a Database Query/Queries that uses the existing query's output without accessing the database tablesfor example:<cfquery>db query reference : #existing query name.ID or name  ....

A DSN is used. These are set up in CF administrator and used in query code to connect to a database.

cfapplication can also be used.

is used to block a piece of code.

Yes, this is possible for example:

<cfif...>
   <cfif...>
      <cfif...>
     
  

The example of nesting of cfml loop while grouping the emloyees through department..one cfoutput loop is nested inside the other...

Yes it supports both .. client as well as session variables

All relational and non relational databse like Oracle,MSAccess,mysql

A variable can be declared dynamically and evaluated using the function EVALUATE()

supports two differnt types of lock, EXCLUSIVE and READONLY. An EXCLUSIVE lock prevents access by any other code and READONLY is more of a flag that marks a block of code that will only be executed if there is no active EXCLUSIVE lock.

the safest way to trasfer files from a client computer to coldfusion is to use Http file upload.

is used for directory access and manipulation. Using ACTION="list" we can get date,time,size and file attributes.

it is .cfm
