66. Write down the Socket object methods to get information about a socket.

1. getInetAddress ()- displays which remote host the Socket is connected to

2. getPort () -displays which port the Socket is connected to on the remote host.

3. getLoca1Port ()- to find the port number for the local end of a connection

4. getLocalAddress () -tells you which network interface a socket is bound to.

67. What operations Multicast Socket Perform?

1. Join a multicast group

2. Send data to the members of the group

3. Receive data from the group

4. Leave the multicast group

68. What are Style Sheets?

Style sheets are collections of style information that are applied to plain text. Style

information includes font attributes such as type size, special effects (bold,italic,underline),

color and alignment. Style sheets also provide broader formatting instructions by specifying

values for quantities such as line spacing and left and right margins.

69. List down the ways of including style information in a document.

1.Linked Styles -Style information is read from a separate file that is specified in the

<LINK> tag

2.Embedded Styles -Style information is defined in the document head using the

<STYLE> and </STYLE> tags.

3.Inline Styles -Style information is placed inside an HTML tag and applies to all

content between that tag and it companion closing tag.

70. Define cascading.

Cascading refers to a certain set of rules that browsers use, in cascading order, to

determine how to use the style information. Such a set of rules is useful in the event of

conflicting style information because the rules would give the browser a way to determine

which style is given precedence.

71. What are the style precedence rules when using multiple approaches?

Inline styles override both linked style sheets and style information stored in the document

head with <STYLE> tag.

Styles defined in the document head override linked style sheets.

Linked style sheets override browser defaults.

72. Give the syntax to specify a characteristic in linked style sheet.

{Characteristic: value}

Multiple characteristic/value pairs should be separated by semicolons.

73. List down font characteristics permitted in style sheets.

1.font-family

2.font-size

3.font-weight

4.font-style

5.font-variant

74. Write a note on content positioning characteristic "Visibility".

Enables the document author to selectively display or conceal positioned content; Possible

values are show or hide.

75. Define XML.

XML is a meta-markup language that provides a format for describing structured data. This

facilitates more structured declarations of content and more meaningful search results across

multiple platforms.
