A webform on a web page allows a user to enter data that is sent to a server for processing. Webforms resemble paper forms because internet users fill out the forms using checkboxes, radio buttons , or text fields.
You are now familiar with the fact that internet presents a two-way communication model, also called theClient-Server Model. In the client server model some data is processed on the client side and certain data is processed by the server on the server side.

Cryptography is the technique of converting a message into unintelligible or non-understandable form such that even if some unauthorized or unwanted person intercepts the message he/she would still not be able to make any sense out of it. Cryptography is thousands of years old.
Techniques used for cryptography Substitution In substitution we replace each letter in the message with another to make the message non-understandable. For example, each letter "a" in the message can be replaced with letter "d" and letter "b" with letter "e" and so on. Transposition It is based on scrambling the characters in a message. A transposition system may first write a message into a table row by row then the message can be read and rewritten column by column to make it scrambled.
str.toLowerCase()
str.toUpperCase()
str.Split()
str.toUpperCase() : Convert to uppercase
str.Split() : splits the string on the basis of blank space.

Data to be delivered on a network has to be converted first into serial transmission. This is done through a device called Network Interface Card (NIC) that must be installed in a computer on the network. NIC has also got printed on it a 48 bits unique address called the MAC or hardware address of the computer machine. In other words, it consists of 12 hexadecimal characters and can have different format as shown below:
- 090017A9B2EF
- 09:00:17:A9:B2:EF
- 09-00-17-A9-B2-EF
