FIRSTLY, BEFORE LEARNING ABOUT THE INFORMATION SYSTEM WE SHOULD KNOW WHAT THE SYSTEM IS. A SYSTEM IS A COLLECTION OF ELEMENTS OR COMPONENTS AND IT HAS INPUTS, PROCESSING MECHANISM, OUTPUTS AND FEEDBACK. SO  INFORMATION SYSTEMS CONSISTS OF INPUT, PROCESS, AND OUTPUT.

In this week, the lecturer gave us three cases relating Information Systems like TPS, MIS, ESS and so we had to explain the systems used in different organizations. This helped me to understand the role and importance of IS in any organization. And I  together with my group had to present my map of IS systems in different fields in my country-Uzbekistan. Others also presented and have learnt about the usage of IS like TPS, MIS, ESS in different fields in different countries. 
To continue during the lecture the teacher gave some case study tasks in which we had to define and explain about the IS system used in 3 organizations, and so we answered the questions by giving explanation about IS systems like TPS, IMS, ESS in a restaurant, company and more. 

THERE ARE MANY COMPONENTS USED TO CONSTRUCT AN I.S.: HARDWARE, SOFTWARE, DATABASES, PEOPLE, AND PROCEDURES.
