Data Is, Information in raw or unorganized form (such as alphabets, numbers, or symbols) that refer to, or represent, conditions, ideas, or objects Ex:- Each student’s test score is one piece of data

Integration of hardware and software technologies and human elements designed to produce timely, integrated, accurate and useful information for decision-making purposes.
Components of CBIS
Input: Captures raw data from organization or external environment
Processing: Converts data into meaningful form
Output: Transfers processed information to people or activities that use it
Feedback: Output returned to appropriate members of organization to help evaluate or correct input stage
Information Systems components
Hardware – desktops, laptops, PDAs
Software – operating systems, application programs
Data – facts and figures entered into computers
Procedures – how the other four components are used
People – users, technologists, IS support
