Question 3. Explain the utility of comments in XML.
Answer: A comment is a note or information that appears in the code of an XML document to help you understand the code better.
Comments are not displayed in the output. They are not part of the program and therefore, are not parsed by the XML parser.

Question 4. State whether the following XML document is well-formed or not
<Student> Mapoj </Student>

Question 8. Write the procedure to link a stylesheet with an XML document.
Answer: Using CSS with an XML Document
To link an XML document with a stylesheet perform the following steps:

Create an XML document and save it as a file with the .xml extension.
Create a stylesheet and save it as a file with the .css , extension.
Link both the files in the XML document by using the PI.
<?xml-stylesheet href = “test.css” type = “text/css”?>

e.g. The following is the CSS document: 
People
{
background-color : light green; 
display : block; 
padding : 5px; 
font-family : arial;
}
Person
{
background-color : pink; 
border : 2px solid black; 
display : block; 
margin-bottom : 5px;
Name
{
font-family : bold; 
display : block;
}
Birthdate 
{
display : block;
}
Eyes
{
display : block;
}
Now, save it as test.css
The following is the XML document:
<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type = "text/css" href = "test.css"?>
<People>
<Person>
<Name>A</Name>
<Birthdate>Jan 24, 1987</Birthdate>
<Eyes>Blue</Eiyes>
</Person>
<Person>
<Name>B</Name>

< Eyes >Brown</Eyes >
</Person>
</People>
Now, save it as test1.xml

Question 9. What do you mean by Processing Instructions (PI)?
Answer: PI can be used to pass information to applications in such a way that escapes most XML rules. Its main use is of linking to an XML stylesheet in the prolog of an XML document. Processing instructions do not have to follow much internal syntax, it can include markup characters without escaping them and can appear anywhere in the document.

<Name> Rahul Sharma </Name>
<City> Delhi </City> </employee>
<employee EmpID="e004">
<Name> Praveen </Name>
<City> Noida </City></employee>
</employees>

Question 3. Compare XML with similar type of other languages.
Answer:

1. Comparing XML and SGML

XML	SGML
XML is a markup language.	SGML is a meta language used to define and describe generic markup language.
It does not include complex and optional features of SGML.	It is complex and requires overheads to use it.
XML allows creation of new tags to describe and present your data.	It is an ISO standard for specifying a set of tags,
XML allows data validation.	SGML does not allow data validation.
It describes the data and transfers data between applications.	It allows you to define and create platform-independent files.

2. Comparing HTML and XML

HTML	XML
HTML tags are predefined.	XML tags are not predefined.
HTML is case insensitive.	XML is case sensitive.
HTML is markup language that creates the form and appearance of the Web page.	XML is neither a programming nor a presentation language.

3. Comparing EDI and XML

EDI	XML
EDI (Electronic Data Interchange) is a collection of standards, formats and file layout.	XML is an emerging standard designed to simplify Web-based E-Commerce transactions between computer application.
EDI enables highly secure document exchanges.	XML document typically needs to be encrypted to maintain security level.
EDI documents are sent via private and relatively expensive Value Added Networks (VANs).	XML documents are generally sent via the Internet.
EDI does not processes low transaction values.	XML processes relatively low transaction values.
EDI allows companies to exchange electronic documents quickly between their trading partners.	XML allows you to create custom tags to present your document in a structured format.

Question 4. Consider the following XML document.
Check this for well- formedness.

<Employees><FirstName> Ambrish
<MiddleName> Kumar</FirstName>
</MiddleName>
<lastname> Garg </LastName>
</Employees>

Answer:

The above XML document is not well-formed.
The document suffers from two errors which are as follows:

Improper nesting The MiddleName element is opened inside the FirstName element, yet MiddleName is not closed before the FirstName element is closed.
Mismatched cases of start and end tags The tag <lastname> is closed with </LastName>, which is incorrect. XML is case sensitive, thus the end tag of <lastname> should be </lastname>.

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:

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.
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.
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.
The XML document cannot contain more than one root element.
The following code is an example of a well-formed document:

<address>
<city> Delhi </city>
<state> Delhi </state>
<country> India </country>
</address>
Consider the same code written in the following way: 
<city> Delhi </city>
<state> Delhi </state>
<country> India </country>
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:

The document must contain atleast one element
The document must have a root element A root element is a unique element in the XML document, which contains the complete document.
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.
XML tags must be closed properly There must be a proper closing tag. In XML, empty tags must end with a following slash.
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).
XML tags are case sensitive XML tags are case sensitive means the opening and ending tags must be in the same case.
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).

Long Answer Type II Questions [10 Marks each]

Question 1. Write two points of difference in HTML and XML. Write three points of well-formed XML document. Write the code to create an XML document to present following data: CBSE 2016

Answer: Two points of difference between HTML and XML follows:

HTML	XML
HTML is a markup language that creates the form and appearance of the Web page.	XML is a text-based markup language for processing and displaying data in a structured format.
HTML documents are viewable in a browser.	XML documents can be viewed only if proper stylesheet file is also available alongwith XML file.

Three points of well-formed XML document are as follows:

The document must have a root element.
The element must have the opening and closing tags.
XML attributes values, should be in double quotation marks.

<?xml version ="1.0" encoding="UTF-8" standalone="yes"?>
<Data><Datal>
<Furniture>Table</Furniture>
<Material >Wood</Material >
<Quantity>75</Quantity>
<Floor>1st</Floor>
</Datal>
<Datal>
<Furniture>Chair</Furniture>
<Materi al >Plastic</Materi al >
<Quantity>85</Quantity>
<Floor>IInd</Floor>
</Datal>
</Data>

Question 2. XML document structure can be divided in which two parts? What is meant by valid XML document (write three points)? Write the code to create an XML document to present following data: CBSE 2014

Answer: XML document structure can be divided into two parts as follows:

Well-formed XML document
Valid XML document

A valid XML document means to follow several terms, such as follows:

It is not only a well-formed document but as well as check error against a DTD.
It signifies that a document is well-formed.
It uses XML parser, XML validator for validation.

The XML code is
<?xml version = "1.0" encoding = "UTF-8"?>
<Employees>
<Employee>
<Name> Srishti </Name>
<Job> Programmer </Job>
<Department> Engineering </Department>
<Cubicle> 5E </Cubicle>
</Employee>
<Employee>
<Name> Aditi </Name>
<Job> Designer </Job>
<Department> Marketing </Department>
<Cubicle> 19T </Cubicle>
</Employee>
</Employees>

Question 3. Write two points of differences between XML and HTML. What is meant by a well-formed XML document (write two points)? Write the code to create an XML document with following data: CBSE 2013

Answer: The differences between XML and HTML are as follows:

HTML has predefined tags while XML has user-defined tags.
HTML document can be viewed directly by the Web browser while XML document cannot be viewed directly and need some proper stylesheet files.

A well-formed document means to follow several generic rules, such as follows:

XML document must contain atleast one element.
All tags must have the opening and closing tags as these XML tags are case sensitive.

The XML code is
<?xml version = "1.0" encoding = "UTF-8"?>
<Travels> <Travel>
<Designation> Singapore </Designation>
<Cost> 200000 </Cost>
<No_of_days> 8 </No_of_days>
<Mode_of_trans> Aeroplane </Mode_of_trans>
</Travel>
</Travel>
<Designation>Shimla</Designation>
<Cost> 10000 </Cost>
<No_of_days> 4</No_of_days>
<Mode_of_trans> Bus </Mode_of_trans>
</Travel></Travels>

Question 4. Explain with a help of an example, how root elements are placed in a XML document?
Answer: XML documents must contain one element that is the parent of all other elements. This element is called the root element. The root element encloses all other elements in XML. All other elements inside the root elements are the form of child element. The structure of the XML file should look like

<root>
<child>
<subchild>....</subchild>
</child>
</root>
e.g.
<company>
<employee>
<ecode> 101 </ecode>
<name> Rahul </name>
</employee>
<employee>
<ecode> 102 </ecode>
<name> Sahil </name>
</employee>
<employee>
<ecode> 103 </ecode>
<name> Muskan </name>
</employee>
</company>

You can see in the above example that the root element declared out here is <company> then comes the child element <employee> which in turn stores the <ecode> and <name> of the employee in the tags.

Answer: Preventions of Spyware
Due to the seriousness of spyware and the harm, it can affect your system and personal information, it is highly recommended you to take the given measures to prevent spyware from overtaking your system:

Download and install anti-spyware software: Most antivirus applications are effective in identifying different types of malware, including spyware, but may not detect all spyware variants. Once you install the anti-spyware software on your computer, you must keep your anti-spyware application updated to keep up with the latest forms of spyware.
Be cautious when Web surfing: The best defense against spyware is not to download it in the first place. Spyware is often installed on your computer when you visit an infected or malicious Website.

Therefore, you should exercise caution with links to Websites from unknown sources. In addition, you should only download programs from trustful Websites. When downloading a specific program, ensure that you are not downloading pirated software. Spyware can be distributed by exploits, that promote software piracy.

Lookout for pop-ups: Malware can lure you into installing spyware on your computer by prompting you with a pop-up window. If you see an unwanted or random pop-up alert, do not click “Agree” or “OK” button to close the pop-up window. This will actually install the malware on your computer. Instead, press Alt + F4 or click on the red “X” on the corner on the pop-up alert to close the window.
Keep current with operating system updates: Important system updates provide significant benefits such as improved security. Just as with any antivirus and anti-spyware software, not keeping up with operating system updates will make your PC vulnerable to the latest malware threats.
Harden your browser settings: Updated Web browsers may help to prevent exploitation by taking several defensive steps against spyware. Most Web browsers will warn you of executable programs and will suggest a safe course of action. In addition to having an updated Web browser, ensure that you have properly configured your browser and that all of your plug-ins and add-ons are updated, including Java, Flash and Adobe products.
Enable your firewall: Firewalls monitor the network and are capable of blocking suspicious traffic, which can prevent spyware from infecting your system.

Question 3. Differentiate between hackers and crackers.
Answer: Differences between hackers and crackers are as follows:

Hackers	Crackers
A hacker is a person intensely interested in the arcane and recondite working of any computer operating system.	A cracker is one who breaks into or otherwise violates the system integrity of remote machines with malicious intent.
Hackers obtain advanced knowledge of operating systems and programming languages.	Having gained unauthorised access, crackers destroy vital data, deny legitimate users service, or cause problems for their targets.
Hackers constantly seek further knowledge, freely share what they have discovered and never intentionally damage data.	Crackers can easily be identified because their actions are malicious.

Question 4. Explain SET, PCI and Kerberos.
Answer:

PCI (Peripheral Component Interconnect) is a computer bus for attaching hardware devices in a computer. These devices can take either the form of an integrated circuit fitted onto the motherboard itself, called a planer device in the PCI specification or an expansion card that fits into a slot.
SET (Secure Electronic Transaction) protocol, which is developed by Visa and Mastercard uses encryption for privacy and digital certificates to verify the three parties -the bank, the customer and the merchant. It ensures secure transactions online.
Kerberos is a third-party authentication that validates the clients over the network and provides secure communication or access to network resources.

Question 5. Write a short note on social networking.
Answer: It is a grouping of individuals into specific groups, like small rural communities or a neighbourhood subdivision, if you will. A social networking service is an online service, platform or site that focuses on facilitating the building of social networks or social relations among people.

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.

Question 3. List some advantages and disadvantages of an E-mail.

Speed E-mail can be sent at a very high speed.
Waste reduction E-mail goes a long way towards reducing the cluster of papers in the modern office, not to mention saving many trees.
Ease of use It is easy to send an E-mail as compared to traditional letter.

Disadvantages of E-mail are as follows:

Hardware requirement You need a computer to read or print E-mail.
Impermanent Your sent mail messages can be altered in all the ways.
A hasty medium It is a limitation because E-mail is so easy to use, it is also easy to send a message that you later regret.
Hard to convey emotions Without the extra clues of voice, posture and expression, it is easy to understand what someone really means in a message.

Question 4. Discuss the structure of an E-mail message.
Answer: In an E-mail message, you will see the following fields which are as follows:

Question 3. Write one example of each field, for which you would use CBSE 2007, 06, 05

Text data type
Memo data type

Answer:

Text data type It allows to store text or combination of text and numbers as well as numbers that don’t require calculations such as phone number. This data type allows maximum 255 characters to store.
e.g. if Employee is a table and Emp_No, Name and Description are fields, then name will be a Text field. Because, name is a character entry field.
Memo data type It allows long blocks of text that uses text formatting, e.g. in the Employee table, the field Description will be of Memo data type, because the length of description of employee may be large.

Question 4. Distinguish between Number and AutoNumber data type field. Give example of each. CBSE 2007, 05

Number	AutoNumber
It holds numeric values which are used for calculations.	It allows to store numbers that are automatically generated for each record.
The field length of this data type is 1,2, 4, 8 or 16 bytes.	The field length of this data type is 4 bytes.
It does not support field property New values.	It supports the field property New values.
e.g. in a table Employee, Salary is a Number type field.	e.g. in a table Bank, the AccountNo is a AutoNumber field as, for every new customer, this field will automatically increase and will provide a new number.

Question 5. Which field properties are used in Office Access 2007? Give the purpose of each field property.
