CS101 - Introduction to Computing - Q.No. 27 ( M - 2 )
What is the difference between the ‘single-line text input field’ and the ‘password input field’?
ANS:
A Password Field is good for sensitive information. The only item that is absolutely necessary is the Submit Button. It is a good idea to include a Reset Button for the convenience of the user.
A text field gathers information using a single line of text. This field is useful for short answers. The default text field is blank. If you want to specify the default text, use the VALUE attribute.

Internet is also called WAN, which means the interconnection of a large number of computer networks and it consists of millions of private, public, academic, business, and government networks of local to global scope that is linked by a broad array of electronic and optical networking technologies.
CS101 - Introduction to Computing - Q.No. 29 ( M - 2 )
In JavaScript, what is event handling? What are the two types of events?
ANS:
Event handling means capturing an event and responding to that.
Events e.g. onMouseOver, OnClick, onLoad, Onunload, updating the clock, etc. are captured by the Javascript & according to the programs they are responded to accordingly

How can we include images on a web page using HTML and Javascript?
ANS:
Image in HTML
It is easier to insert images and pictures i.e. JPG, GIF & BMP files in the web page through HTM codes.
The tag is used which is used as under:-
Height=(in pixels) width=(in pixels)
Images in JavaScript
Images in JavaScript may be used with the event handling i.e. OnLoad, OnUnload, OnError, and OnAbort, etc.
The properties i.e. used for Java script are as under:-
1. Name
2. Border
3. Complete
4. Height
5. src
for example:-XYZ” src=”abc.jpg”>

Elaborate Rester Graphics with examples.
ANS:
Raster graphics are digital images created or captured (for example, by scanning in a photo) as a set of samples of a given space. A raster file is usually larger than a vector graphics image file. A raster file is usually difficult to modify without loss of information.
Examples of raster image file types are BMP, TIFF, GIF, and JPEG files. CS101 - Introduction to Computing - Q.No. 34 ( M - 5 ) What is a Relational Database? Give the names of any three RDBMS software. (2+3) ANS: Database architecture consists of three levels, external, conceptual, and internal. Clearly separating the three levels was a major feature of the relational database. NAMES: Oracle Database software, Linux, and oracle e-business database software, and Oracle OLAP.
CS101 - Introduction to Computing - Q.No. 35 ( M - 5 ) How many ways are there to call a function in a program? Explain with example ANS: there are two methods of function in a program
1st method is used within the HTML coding with immediate in the even handling
on the other side function can also be defined in the heading portion of the HTML page.
it is a better choice to use function as it includes many statements in it.
OnMouseOver=“if(document.sendEmail.sender.value.length<1)
Window.alert(‘empty field!’)”
while in the heading portion
it will be as
function checkForm() {
if ( document.sendEmail.sender.value.length < 1) {
window.alert( “Empty Field” );
}
