1. Input Devices : Such as Keyboard, Mouse etc.

2. CPU: It has three components – The control unit, memory unit and the logical unit.

3. Output Devices: Such As Monitor, Printer.

4. Hardware & Software

The System Software such as MS DOS, Windows 7 etc.- are a set of programs which control the operations & help processing.
The Application software such as MS Word, Tally etc. enables the user to perform useful specific functions.

Management Information System (MIS): Is an information system that provides the needed information to the managers to manage the organization effectively. It combines the three resources viz; technology, information & people for the efficient management of an enterprise.

3. Reliability : The information is reliable.
4. Real Time User Interface : AIS enables direct & simultaneous interaction between user & the machine. 

Limitations of Computerized AIS :
1. Staff Opposition : As it reduces the no of employees, staff usually opposes it.
2. High Development Costs : Development requires qualified engineering staff & training also, so it‟s a costly affair.

Limitations of DBMS:

1. High setting up costs
2. Lack of Expertise Knowledge
3. Security Problems
