What is Data?Data consists of a series of facts or statements that may have been collected, stored, processed and/or manipulated but have not been organized or placed into context.
When data is organized or arranged in a meaningful manner, it becomes information.

ACCURATE
Accurate information is error free. In some cases inaccurate information is generated because inaccurate data is fed into the transformation process.
COMPLETE
Complete Information contains all the important facts.
ECONOMICAL
Information should be relatively economical to produce.
RELIABLE
Reliable information can be dependent on. In many cases, the reliability of the information depends on the reliability of the data collection method.

What is a System?
A system is set of elements or components that interact to accomplish goals.
The elements themselves and the relationships among them determine how the system works.
System have inputs, processing mechanisms, outputs and feedback.

Computer-Based Information System
( C B I S )
A computer based information system (CBIS) is a single set of hardware, software, databases, telecommunications, people, and procedures that are configured to collect, manipulate, store and process data into information
For example :
Payroll System
Order Entry System
Inventory Control System

Hardware
Hardware consists of computer equipment used to perform input, processing and output activities.
Tangible parts of computer systems
Hardware includes :
Input Devices
Processing Devices
Output Devices
Storage Devices

Software
Software is the computer programs that govern the operation of the computer. These programs allow the computer to, for example, process payroll, send bills to customers and provide better customer service
There are two basic types of software:
System Software
Application Software
