Long Answer Type Questions [5 Marks each]

Question 1. When using a search engine to search, then would you use quotation marks around search terms? CBSE 2007

Answer:

 Quotation marks should be used around a phrase or search terms. Surrounding terms with quotation marks limit the search results to only those Web pages that contain the exact phrase, we have specified.

 Doing this ensures that, the concept will be searched for as a whole and not picked apart by the search engine or we can say, without the quotation marks, the results will include any page that contains the words we have used regardless of what order those words are in.

 E.g. typing death penalty without quotation marks could potentially retrieve all items that mention death, all items that mention penalty as well as the items about death penalty. This could lead to results that seem to have nothing to do with your topic. For best results, you should write “death penalty”.

Question 2. Transferring files through E-mail is restricted due to fill size. Justify.

Answer:

 Over the Internet, a message will often pass through several mail transfer agents to reach the recipients. Each of these has to store the message before forwarding it on and many therefore, need to impose size limits.

 The result is that while large attachments may internally send within an organisation, they are unreliable when sending across Internet.

 E.g. In general, 10 MB is considered safe for the maximum size of an E-mail but, Google’s Gmail service increased its limit to 25 MB.

Write the steps to design a database.

Answer: Steps to Design a Database There are various steps to design a database which are as follows:

 Step 1 Determine the purpose of your database The first step of designing a database is to determine the purpose and mechanism to design and use it.

 Step 2 Determine the tables Tables are one of the most important elements of a database, consist of rows and columns. To create a well-defined database, you have to keep some conditions which are as follows:  A table should not contain duplicate information.  Each table should contain information about one subject. e.g. One table is used to contain the personal information of the students and the other is used to contain the marks scored by the student.  Step 3 Determine the fields After creating a table, you need to decide the type and number of fields required for the tables in your database. Each field in a table contains individual facts about the table’s subject. e.g. A customer table may include company name, address, city, state and phone number fields.

 Step 4 Identify the primary key in a table From the fields of table, you need to identify a primary key which uniquely identifies each individual record of the table. The primary key helps you to reduce data duplication in the table.  Step 5 Determine the relationship between tables In this step, you need to determine relationship between two or more tables in your database. You can set- up a relationship between tables on the basis of common field between them. Establishing a relationship allows you to fetch any information from both the tables.  Step 6 Refine the design After you have designed the tables, fields and relationships, its time to study the design and detect any faults that might remain.  Step 7 Enter data and create other database objects When you are satisfied that the database structure meets the goals you needed, add all your existing data to the tables.

Long Answer Type Questions [5 Marks each] Question 1. Explain various attributes of tag.
Answer:
Attributes of Tag An attribute is an extra piece of information associated with a tag that provides further details about the tag. Following are the various attributes of tag:
The src Attribute: The src (source) attribute takes URL (Universal Resource Locator) of an image file as value, which points to the direct location of an image to be displayed. The image that you specify in your tag should be in your computer otherwise the image will not be displayed and in place of image a cross mark in a box 0 will appear.
The alt Attribute: This attribute of tag is used to provide alternate text when an image on a Web page cannot be displayed. The alternative text is the text associated with an image that serves the same purpose and conveys the same essential message. As per HTML standard, alt attribute is optional but is highly recommended.
The align Attribute: This attribute is used to set the position of an image in a Web page according to the user’s requirements. In HTML, images appear inline with a single line of the text. But, HTML standard does not define a default alignment for the images with respect to other text and images in the same line. There are some values of image alignment attribute as follows:
1. Top Alignment 2. Middle Alignment 3. Bottom Alignment 4. Left Alignment 5. Right Alignment
The width and height Attributes: When an image is added to a Web page, it is not mandatory to specify width and height of the image. At the time of loading an image, a box will appear on the place where the image will be loaded.
The border Attribute: You can set the border of an image that you want to use in your Web page. The border attribute of the tag specifies the width of the border around an image. By default, an image has no border in HTML.
Question 2. Which attribute is used to specify the location of an image file in tag? Explain.
Answer: The attribute you need to get an image to display on a Web page is the src attribute. In the src attribute of the tag, you can specify the path of the image that you want to add to the Web page. This may be an image in the same directory, an image somewhere else on the same server, or an image stored on another server. The syntax for src attribute is
Question 3. Define various alignments of align attribute with example.
Answer: There are some values of image alignment attribute as follows:
Middle Alignment This alignment is different in both Internet Explorer and Mozilla Firefox. In Internet Explorer, this alignment aligns the image to the middle of the tallest item in the current line. While in Mozilla Firefox, this alignment aligns the image to the baseline of the current line in which it is placed.
Example: To show middle alignment of an image. Alignment
Middle Alignment A flower, sometimes known as a b'oom or blossom, is the reproductive structure found in flowering plants. The biological function of a flower is to effect reproduction, usually by providing a mechanism for the union of sperm with eggs.
Bottom Alignment This alignment aligns the bottom edge of the image, to the same horizontal plane as the baseline of the text. Both Internet Explorer and Mozilla Firefox treat this alignment in the same manner.
Example: To show bottom alignment of an image. Alignment
Bottom Alignment
A flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants. The biological function of a flower is to effect reproduction, usually by providing a mechanism for the union of sperm with eggs.
Left Alignment This alignment aligns the image to the left on the Web page respectively of the browser window.
Example: To show left alignment of an image. Alignment
Left Alignment
A flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants. The biological function of a flower is to effect reproduction, usually by providing a mechanism for the union of sperm with eggs.

Question 5. Explain the following (with example):
1. linking on same Web page. 2. linking on different Web page.
Answer:
Linking on the Same Web Page
To create an internal link, you need to use a pair of tags. The first tag is used to specify the name of the target location for identification purpose. It is known as target fragment. You can use the tag with its name or id attribute to identify a fragment. This type of anchor is commonly called as named anchor.
The first step is to make the target fragment. The simple syntax to do so is written below:
Part A Where, “aa” is the name of fragment/segment you want to refer (like top, bottom etc.). The second tag is used to create a link to the target fragment. The simple syntax to link to the target segment is written below:
ClickHere In the second tag, the value of href attribute with # symbol is to be specified.
Example: To show the internal linking in an HTML document. Internal Linking<title></head> <body> <h1>Linking in a page </h1> <h3>Click here to go to the <a href="#bottom">bottom</a> of the page.</h3> > > > <a name="bottom"><h3> You are at the bottom of the page.</h3></a> </body> </html> Output: Linking Sections of Different Web Pages Internal linking enables us to link sections of different Web pages also. It can be done by specifying the name of the Web page and the section which is to be linked. To link two Web pages, you first need name to the section by using name attribute of <a> tag that you want to link. Suppose, we need to link a section of HTML1.html to HTML2.html. Create a named anchor in HTML1.html. The syntax is given below: <a name =”link”> Different Page </a> After this, you have to write the code to refer to it, from Web page HTML2.html. Following is the code to do so: <a href =”HTML1.html#link”> Here, HTMLl.html is the name of html file to the section of which you want to link and # link is the segment name you want to link in that html file.

Question 4. Consider the following XML document. Check this for well- formedness.
Ambrish Kumar Garg
Answer:
The above XML document is not well-formed. The document suffers from two errors which are as follows:
1. Improper nesting The MiddleName element is opened inside the FirstName element, yet MiddleName is not closed before the FirstName element is closed. 2. Mismatched cases of start and end tags The tag is closed with , which is incorrect. XML is case sensitive, thus the end tag of should be .
Question 5. Explain the structure of XML document.
Answer: Structure of XML- File/Document Every XML document includes both physical and logical structure which are as follows:
1. Physical Structure It contains the actual data used in a document. The basic storage unit called entity, each of which may refer to other entities. An entity has a name and content. It contains references to other entities. There is a special entity called document entity or root, that serves as a main storage unit. XML processor always start document processing from that unit. We have three classifications of entities, these are as follows: 1. Internal and External Entities For internal entity, there is no separate physical storage object and the content of the entity is given in the declaration. It contained inside the document. If the entity is not internal, then it is an external entity.
2. General and Parameter Entities General entities are entities which are used within the document content. In this specification, general entities are sometimes referred to with the unqualified entity, when this leads to no ambiguity. Generally, entities are declared and used differently. Parameter entities are parsed and used only in the DTD part of the XML document. 3. Parsed and Unparsed Entities Parsed entities contain text that is referred as replacement text intended to be processed by the parser and is considered as an integral part of the document. Unparsed entities are resources that can be of any type including text objects. This type of entity is never process by parser.
2. Logical Structure It is a template that enables the elements to be included in a document and in the order in which they have to be included. The logical structure includes the basic components of the XML document. It indicates how a document is built, irrespective of what a document contains. The first structural element is prolog which is the base for the logical structure. The structure of the document of example code:
Question 6. A well-formed document must have a root element. Explain with an example.
Answer: To create a well-formed XML document, it is necessary for it to have a root element. A root element is a unique element that contains all other elements in the XML document.

Delhi Delhi India
Consider the same code written in the following way: Delhi Delhi India The preceding code is not a well-formed document, since it does not contain a root element.
Question 7. Explain the difference between a well-formed and a valid XML documents. CBSE 2011
Answer:
1. Well-Formed XML Documents
A “Well-Formed” XML document means that document has the correct XML syntax. The XML document that follows XML grammar rules is called well-formed document. A document that includes sequence of markup characters that cannot be parsed or are invalid cannot be well-formed. The following points are to be kept in mind for a valid XML document:
1. The document must contain atleast one element
2. The document must have a root element A root element is a unique element in the XML document, which contains the complete document.
3. The element must have the opening and the closing tags To close a tag, you need to prefix the forward slash with the normal tag.
4. XML tags must be closed properly There must be a proper closing tag. In XML, empty tags must end with a following slash.
5. XML elements must be properly nested The parent element has to be opened before the child element and closed after the child element.
This code is not well-formed because the root element (College) is closed before the parent element (Student).
6. XML tags are case sensitive XML tags are case sensitive means the opening and ending tags must be in the same case.
7. XML attribute values should be in double quotation marks The attribute value in an XML document should be enclosed in proper quotes.
2. Valid XML Document
A valid XML document is .not only a well-formed document but as well as they also checked error against a DTD or schema. DTD is a set of rules that defines what tags appear, what value those tags may contain and how the tags are related to each other in an XML document. Validation can be done only if the XML document has valid DTD. When an XML document is checked or parsed according to a particular structure or guidelines, the process is known as validation of the document.
Question 8. Define CSS. How to create a CSS file?
Answer: CSS is a simple design language intended to simplify the process of making Web pages presentable. CSS is a type of stylesheet and this stylesheet consists of a list of rules. You can include a CSS in multiple XML documents that have the same data structure.
Syntax selector { property: value; } Declaration Block }
Creating a CSS File To create a CSS file, you need to have all the style rules composed in it and save it with extension .css.
You can define the color in CSS by name as well as by code like green color may be written as #008000 or rgb(0,128,0).
