Internet

The Internet is a global system of interconnected computer networks that use the standard Internet protocol suite (often called TCP/IP, although not all applications use TCP) to serve billions of users worldwide.



                                                                                   It is a network of networks that consists of millions of private, public, academic, business, and government networks, of local to global scope, that are linked by a broad array of electronic, wireless and optical networking technologies. 

               

         The Internet carries an extensive range of information resources and services,such as the inter-linked hypertext documents of the      World Wide Web (WWW)  and the infrastructure to support email.

Web applications

                    Types of web

 A web application is an application that is accessed by users over a network such as the Internet or an intranet. The term may also mean a computer software application that is coded in a browser-supported programming language (such as JavaScript, combined with a browser-rendered markup language like HTML) and reliant on a common web browser to render the application executable.

Web applications are popular due to the ubiquity of web browsers, and the convenience of using a web browser as a client, sometimes called a thin client. The ability to update and maintain web applications without distributing and installing software on potentially thousands of client computers is a key reason for their popularity, as is the inherent support for cross-platform compatibility. Common web applications include web mail, online retail sales, online auctions, wikis and many other functions.

Relational database

A relational database is a collection of data items organized as a set of formally described tables from which data can be accessed easily. A relational database is created using the relational model. The software used in a relational database is called a relational database management system (RDBMS). A relational database is the predominant choice in storing data, over other models like the hierarchical database model or the network model. It consists of n number tables and each table has its own primary key.

Relational database theory uses a set of mathematical terms, which are roughly equivalent to SQL database terminology. The table below summarizes some of the most important relational database terms and their SQL database equivalents.

Information system

Data、Information and IM

Week one

This week I started new course on IT , and also I've started to know about IT . First , IT's full name is Information Technology.It's a good beginning for me  perhaps .

DO
NOT
BE
DOUBE .
ITS
ME .

Follow our lectuer miss Zainal@ , I understood the difference betwent Date and Information .

EXAMPLE:

Definition of  DATA:

Data is something same as symbols . We compile those symbols into computer become information such as music , picture , video and others .

Definition of INFORMATION:

Information is complete data . Everything we take from internet is information .

Computers process data into information . That is great ,isn't it .

IM ( Information management) is the collect and manage various information from different space .
