Following are the types of Application Softwares:- AutoCAD and Corel Draw Business Software Productivity SW Games Software Question No: 28 ( Marks: 2 ) Why Local variable is preferred over Global variable? In my point of view Global variable has some advantage with Local variables is preferred due to the following reasons:- When we declare any global variable in web page then in case of error and logic it s very difficult to see on which line this variable is used and what s 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 the reuse and maintenance of your code much more complex. Question No: 29 ( Marks: 2 ) 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 and come back. Now we can also interact with server side with the help of AJAX in JavaScript function.
In-Line Event Handling We can place event handlers in the BODY part and also in HTML attributes the event handlers 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. Question No: 30 ( Marks: 2 ) What is Structured Vector Graphics?

And which old professions are being eliminated? Due to computing where people are getting benefits from automated systems on the other hand the people that are with KHATA system or Manual system and they don t 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. Question No: 32 ( Marks: 3 )
What are Logic- or Time-Bombs? It execute the payload when predetermined event occurs For example use type particular phrase and particular data is reached. Question No: 33 ( Marks: 3 ) 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 day s many software are available for uploading files using FTP like Mozila FTP, cute FTP etc. Question No: 34 ( Marks: 5 ) Why should we, as computing professionals, be interested in studying the social implications 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 and select future direction accordingly. Computers are keep becoming more and more powerful and gaining more autonomy. Powerful Global Corporation.
