WHAT IS CRYPTOGRAPHY

Everyone has secrets; some have more than others. When it becomes necessary to transmit those secrets from one point to another, it's important to protect the information while it's in transit. Cryptography presents various methods for taking legible, readable data, and transforming it into unreadable data for the purpose of secure transmission, and then using a key to transform it back into readable data when it reaches its destination.

Predating computers by thousands of years, cryptography has its roots in basic transposition ciphers, which assigns each letter of the alphabet a particular value. A simple example is to assign each letter a progressively higher number, where A=1, B=2, and so forth. Using this formula for example, the word "wise GEEK", once encrypted, would read "23 9 19 5 7 5 5 11". During World War Two, machines were invented that made the ciphers more complicated and difficult to break, and today, computers have made cryptography even stronger still.

Importance of IT in Commerce

While we are taking about Importance of it in Commerce. So First we need that we fully Understand with IT and Commerce. After that we easily determine importance of IT in Commerce.

What Is IT

IT stands for Information Technology. Information Technology is the use of computers and software to manage information. In some companies, this is referred to as Management Information Services (or MIS) or simply as Information Services (or IS). The information technology department of a large company would be responsible for storing information, protecting information, processing the information, transmitting the information as necessary,

What is An Artificial Intelligence

“Artificial Intelligence is the science and engineering of making intelligent machines, especially intelligent computer programs. It is related to the similar task of using computers to understand human intelligence, but AI does not have to confine itself to methods that are biologically observable. The term was coined in 1956 by John McCarthy at the Massachusetts Institute of Technology. “

Artificial intelligence includes

What Is An Application

First, this is necessary, we known that what is program and Software. In Easy way we can say. Group of instruction called as a Program. And group of program is called as Software.

Software Defines in Two Categories.

1- System Software

2- Application Software
