Why Local variable is preferred over Global variable ?

In my point of view Global variable has some advantage with Local variables is preferreddue to the following reasons:-

When we declare any global variable in web page then in case of error and logic its very

difficult to see on which line this variable is used and whats his value if we have more

than 2000 lines and all the functions in web page using that Global Variable so Global

variables can make the logic of a Web page difficult to understand.

As we know we can use Global variable everywhere so Global variables also make thereuse and maintenance of your code much more complex.


In JavaScript, what is event handling? What are the two types of events?

In java script we can capture events on do some operation on the basis of that particular

event. For example we want to load some data on web page then with the help of event

handling we can do this operation by using onLoad event.

We can put Event handlers in the body of web page and also in attributes of HTML.

From the attribute we can call any JavaScript function that will do his operation andcome back. Now we can also interact with server side with the help of AJAX in

JavaScript function.


18/48

In-Line Event Handling

We can place event handlers in the BODY part and also in HTML attributes the eventhandlers attributes consist of 3 parts the event handler, equal sign and a string of

JavaScript statement enclosed in quotes (single or double). And one more thing these

should be put in one line without newline due to this sophisticated event handling is not

possible with in-line event handling.


What is Structured Vector Graphics ?

This is a plug-in that is required to view swf (flash) files in the web browser


What kind of new jobs are created because of computing? And which old professions are

being eliminated?

Due to computing where people are getting benefits from automated systems on the otherhand the people that are with KHATA system or Manual system and they dont know

about computers are eliminated due to this reason and people take place of many people.

We can see in the offices where before computer if there are four person required now

only one person is required for example with the help of database we can store more than

thousand of information and only one person is managing the whole data that is DBA. In

the old system many people are writing the data in registers and then its also very

difficult to find the specific record.

Now we can see companies are hiring:-

Data Entry Operators

System Engineers

Software Developer

DBA etc.



19/48

What are Logic- or Time-Bombs ?

It execute the payload when predetermined event occursFor example use type particular phrase and particular data is reached.


What do you mean by FTP or File Transfer Protocol?

This protocol is used to upload the files on remote computers. This is used to transfer

files between computer on TCP/IP network e.g. internet and now a days many software

are available for uploading files using FTP like Mozila FTP, cute FTP etc.


Why should we, as computing professionals, be interested in studying the socialimplications of our creations?

If we see our life then we can judge computing technology is changing our life fast if we

compare with other technology.

We should highlight the mistakes and successes of the past. We should learn then andselect future direction accordingly. Computers are keep becoming more and more

powerful and gaining more autonomy.

Powerful Global Corporation.
