Long Answer Type Questions [5 Marks each]

Question 1. Explain various attributes of <img> tag.
Answer:

Attributes of <img> 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 <img> 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 <img> 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 <img> 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:

Top Alignment
Middle Alignment
Bottom Alignment
Left Alignment
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 <img> 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 <img> 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 <img> 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 <img src =”imagel. jpg”>

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.
<html>
<head>
<title> Alignment </title>
</head>
<body>
<h1> Middle Alignment </ h1>
<img src="flower2.jpg" align="middle">
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.
</body>
</html>

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.
<html>
<head> <title> Alignment </title> </head>
<body>
<h1> Bottom Alignment </h1>
<img src="flower2.jpg" alt="flower" align="bottom">
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.
</body>
</html>

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.
<html>
<head> <title> Alignment </title> </head>
 <body>
<h1> Left Alignment </h1>
<img src="flower2.jpg" align="left">
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.
</body>
</html>

Right Alignment
This alignment aligns the image to the right on the Web page respectively of the browser window.

Example: To show right alignment of an image.
<html>
<head> <title> Right Alignment </title> </head>
<body>
<h1> Right Alignment </h1>
Cimg src="flower2.jpg" align="right">
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.
</body> 
</html>

Question 4. Write HTML code to illustrate

listed hyperlinks
image hyperlinks

Answer:

Listed Hyperlinks: It is noticeable that <a> tag can also be used for more complex task (as with images or with lists etc.)

Example: To show listed hyperlinks.
<html>
<head> <title> List </title> </head>
<body> <h1>List </h1>
<ul>
<li> <a href="linkl.html"><img src ="F:Fruits-wallpaper-91.jpg" align="middle" height="75" width="75">
Fruit Chart </a></li><br><br>
<li> <a href= "link2.html">
<img src="F:\vegetable.jpg" align="middle" width="75" height="75">
Vegetable Chart </a> </li > </ul>
</body>
</html>

Output:

Image Hyperlinks: Images can also be used as hyperlinks. To create image as a link, following syntax is used:
<a href = “URL”> <img src=”image1.jpg”> </a>

Example: To show image as link.
 <html>
 <head>
 < title>Image as Link</title)
 </head>
 <body>
 <a href "http://en.wikipedia.org/wiki/Tweety")
 <img src="D:\Class10\computer\tweetyl.jpg"></a>
 </body>
 </html>

Question 5. Explain the following (with example):

linking on same Web page.
linking on different Web page.

Answer:

Linking on the Same Web Page

To create an internal link, you need to use a pair of <a> tags. The first <a> tag is used to specify the name of the target location for identification purpose. It is known as target fragment. You can use the <a> 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:
<a name =”aa”> Part A </a>
Where, “aa” is the name of fragment/segment you want to refer (like top, bottom etc.). The second <a> tag is used to create a link to the target fragment. The simple syntax to link to the target segment is written below:
<a href = “#aa”> ClickHere </a>
In the second <a> tag, the value of href attribute with # symbol is to be specified.

Example: To show the internal linking in an HTML document.
<html>
<head><title>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>
<br>><br><br><br><br><br><br><br><br> 
<br>><br><br><br><br><br><br><br><br>
<br>><br><br><br><br><br><br><br><br>
<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.

Long Answer Type Questions [5 Marks each]

Question 1. Why is Internet called ‘Network of Networks’?
Answer:

Internet is called ‘Network of Networks’ because it is global network of computers that are linked together by cables and telephone lines making communication possible among them. It can be defined as a global network over a million of smaller heterogeneous computer networks.
The network which consists of thousands of networks spanning the entire globe is known as Internet.
The Internet is a world wide collection of networked computers, which are able to exchange information with each other very quickly.
Mostly people use the Internet in two ways, E-mail and World Wide Web. In Internet, most computers are not connected directly, they are connected to smaller networks, which in turn are connected through gateways to the Internet backbone.
A gateway is a device that connects dissimilar networks. A backbone is central interconnecting structure that connects one or more networks.

It translates meaningful domain names into the numerical IP addresses, which is needed for the purpose of locating computer services and devices world wide.
It serves as the phone book for the Internet by translating human friendly computer host names into IP addresses.
The DNS can be quickly updated, allowing a service’s location on the network to change without affecting the end users.
It distributes the responsibility of assigning domain names and mapping those names to IP addresses by designating authoritative names servers for each domain.
It also specifies the technical functionality of database service. It defines the DNS protocol, a detailed specification of the data structure and data communication exchanges used in DNS, as part of the Internet Protocol Suite (IPS).

Question 3. Give an example of E-mail address and explain each part of it.

Long Answer Type Questions [5 Marks each]

Question 1. Discuss the components of a database.
Answer: A database consists of several components. Each component plays an important role in the database system environment.
The major components of database are as follows:

Data
It is raw numbers, characters or facts represented by value. Most of the organisations generate, store and process large amount of data. The data acts as a bridge between the hardware and the software. Data may be of different types such as User data, Metadata and Application Metadata.
Software
It is a set of programs that lies between the stored data and the users of database. It is used to control and manage the overall computerised database. It uses different types of software such as MySQL, Oracle etc.
Hardware
It is the physical aspect of computer, telecommunication and database, which consists of the secondary storage devices such as magnetic disks, optical discs etc., on which data is stored.
Users
It is the person, who needs information from the database to carry out its primary business responsibilities.

The various types of users which can access the database system are as follows:

Database Administrator (DBA)
A person, who is responsible for managing or establishing policies for the maintenance and handling the overall database management system is called DBA.
Application Programmers
The people, who write application programs in programming languages to interact and manipulate the database are called application programmers.
End-user
A person, who interacts with the database system to perform different operations on the database like inserting, deleting etc., through menus or forms.

Question 2. Define database management system. Write two advantages of using database management system for school. CBSE 2007,05, 04
Answer: DataBase Management System (DBMS) is a collection of programs that enable users to create, maintain database and control all the access to the database. The primary goal of the DBMS is to provide an environment that is both convenient and efficient for user to retrieve and store information.

The advantages of using DBMS for school are as follows:

In school, DBMS is used to store the data about students, teachers and any other related thing at a centralised location.
It provides security to the personal information of the school, stored in it.

Question 3. Distinguish between a record and a field in a table, with an example. CBSE 2007,05
Answer: Distinguish between a record and a field in a table are as follows:

Record	Field
It is a collection of data items, which represent a complete unit of information about a thing or a person.	It is an area within the record reserved for a specific piece of data.
A record refers to a row in the table.	A field refers to a column in the table.
Record is also known as tuple.	Field is also known as attribute.
e.g. if Employee is a table, then entire information of an employee is called a record.	e.g. if Empolyee is a table, then empld, empName, department, salary are the fields.

Question 4. 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.

Application Oriented Questions

Question 1. Consider the following table

Which of the above field can be selected as a primary key?
EmpName field also has unique values for all the records. Can it be made primary key? Give answer with reason.

Answer:

EmpNo can be selected as a primary key.
EmpName is having unique values, but there is no guarantee that if more employees are included then there would not be multiple people with similar names.
So, in future its values may be duplicate. Thus, it cannot be made as a primary key.
