    Topic 3: Information System

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.

THE  INFORMATION SYSTEM IS AN APPLICATION OF COMBINATION OF HARDWARE, SOFTWARE, INFRASTRUCTURE, AND PERSONNEL THAT SUPPORTS 

PLANNING, CONTROL, COORDINATION, AND DECISION MAKING IN AN ORGANIZATION. THEREFORE, INFORMATION SYSTEM IN ORGANISATION INCLUDES BUSINESS, PEOPLE AND INFORMATION. 

 THERE ARE MANY TYPES OF I.S.:

              
               1.TRANSACTION PROCESSING SYSTEM(TPS)

               2.DECISION SUPPORT SYSTEM(DSS)

               3.EXPERT SUPPORT SYSTEM (ESS)    

               4.MANAGEMENT INFORMATION SYSTEM(MIS)

               5.OFFICE AUTOMATION SYSTEM(OAS)

            

I.S.  CAN BE USED TO SUPPORT BUSINESS OPERATIONS AND SUPPORT DECISION MAKING MANAGEMENT.  IT WILL OPERATE TRANSACTION PROCESSING SYSTEMS, OFFICE MANAGEMENT SYSTEM AND ENTERPRISE COLLABORATION SYSTEMS. IN ADDITION, I.S.  SUPPORTS MANAGEMENT SUPPORT SYSTEMS, INFORMATION SYSTEMS DECISION SUPPORT SYSTEMS AND EXECUTIVE INFORMATION SYSTEMS.

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.

                                     TOPIC 2: IT AND ICT 

WHAT IS ICT? 

ICT( INFORMATION COMMUNICATION AND TECHNOLOGY) IS THE COLLECTION OF COMMUNICATION TECHNOLOGIES LIKE: THE INTERNET, NETWORKS, MOBILE PHONES AND OTHERS.   THEREFORE, ICT CONSISTS OF IT AND MEDIA BROADCASTING AND IS USED IN MANY PROFESSIONAL FIELDS SUCH SCIENCE, MEDICINE,EDUCATION, BANKING, BUSINESS AND GOVERNMENT.  

FOR INSTANCE, IN EDUCATION ICT IS USED IN E-LEARNING,  IN COMPUTER LABS AND OTHER TOOLS. ICT IS ALSO ESSENTIAL IN BANKING FOR EXAMPLE, E-BANKING, ATM, SMART CARDS, E-FUNDS TRANSFER, AND E-DATA INTERCHANGE. MOREOVER, BUSINESS ORGANIZATIONS ARE HIGHLY DEPENDENT ON ICT BECAUSE THEY USE MOBILE PHONES, LAPTOPS AND PC, EMAIL, E-BUSINESS TO COMMUNICATE WITH COLLEAGUES AND RUN THE BUSINESS.  

WHAT IS IT? 

IT(INFORMATION TECHNOLOGY) IS THE NAME OF TECHNOLOGY THAT IS USED FOR CREATING, STORING, EXCHANGING, AND CONSUMPTION OF INFORMATION. OR SIMPLY PEOPLE USE IT TO HELP THE INFORMATION AND THE PROCESS OF COLLECTING INFORMATION IN ANY ORGANIZATION. FOR INSTANCE, INTERNET SITES, CELLULAR PHONES, FAX MACHINES, AND MORE. 

IT HAS ITS TECHNOLOGY ARCHITECTURE WHICH IS:

A MAP OR PLAN OF THE INFORMATION TOOLS IN ANY ORGANISATION.

AND THIS ARCHITECTURE HAS THE ENTIRE ORGANIZATION'S BUSINESS NEEDS FOR INFO, AND INFRASTRUCTURE AND OTHER TOOLS.

INFORMATION TECHNOLOGY INFRASTRUCTURE CONSISTS OF ALL PHYSICAL AMENITIES: IT COMPONENTS, IT SERVICES, AND IT PERSONNEL THAT CONTROL THE ENTIRE ORGANIZATION. 

-IT COMPONENTS ARE: COMPUTER HARDWARE, SOFTWARE, AND COMMUNICATION TECHNOLOGIES.

-IT PERSONNEL IS PEOPLE WHO WORK WITH IT AND IS

-IT SERVICES ARE DATA MANAGEMENT, SYSTEMS DEVELOPMENT AND SECURITY MANAGEMENT. 

During this week we had an activity about how the ICT and IT are applied in healthcare, educational system and business. In addition, we had a group discussion about the difference between IT and ICT. By discussing and activity the lesson became more interesting and productive.

TO CONCLUDE, NOW I KNOW THE DIFFERENCE BETWEEN ICT AND IT, AND I'M EAGER TO LEARN MORE ABOUT IT.

INFORMATION TECHNOLOGY FCC 123 TOPIC 1

INTRODUCTION TO INFORMATION AND TECHNOLOGY FCC 123 

TOPIC 1 : Data, Information and Information Management 

FIRST OF ALL, WE SHOULD KNOW SOME BASIC INFORMATION ABOUT COMPUTER AND COMPUTER GENERATIONS IN ORDER TO UNDERSTAND THE DIFFERENCES BETWEEN DATA AND INFORMATION, THE PROBLEMS OF INFORMATION MANAGEMENT.

 A COMPUTER IS A PROGRAMMABLE MACHINE THAT DOES WHAT WE INSTRUCTED IT TO DO. IN ADDITION, THERE ARE 4 BASIC OPERATIONS THAT A COMPUTER DOES: INPUT, PROCESSING, OUTPUT AND STORAGE AND MAYBE, COMMUNICATION.  

 MOREOVER, THERE ARE 5 GENERATIONS OF COMPUTERS: 1ST GENERATION-ENIAC (ELECTRONIC NUMERICAL INTEGRATOR AND COMPUTERS) USED VACUUM TUBE. 2ND GENERATION OF COMPUTERS USED TRANSISTORS AND USED HIGH LEVEL LANGUAGES(COBOL), 3RD GENERATION USED MICROCHIPS AND OS AND MONITOR. 4TH GENERATION  USES MICROCHIPS AND MORE HUMAN FRIENDLY. 5TH GENERATION COMPUTER IS THE COMPUTER WE ARE USING NOW AND IT IS BASED ON AI(ARTIFICIAL INTELLIGENCE) AND CAN BE USED BY VOICE AND TOUCH.

          THERE ARE 6 CATEGORIES OF COMPUTERS:

          1. EMBEDDED

          2. MOBILE COMPUTERS

          3. PERSONAL COMPUTERS

          4. MID-RANGE COMPUTERS

          5. MAINFRAME 

          6. SUPERCOMPUTERS 

          AND NOW IT'S TIME TO EXPLAIN THE DIFFERENCE BETWEEN DATA AND INFORMATION. 

DATA IS A RAW MATERIAL LIKE NUMBERS, SYMBOLS AND PICTURES ETC. DATA CANNOT BE USED FOR ANYTHING WHEN IT IS IN THAT FORM. 

 INFORMATION IS THE PROCESSED DATA THAT CAN BE VERY USEFUL AND IMPORTANT WHEN MAKING RIGHT DECISIONS IN BUSINESS IT MANAGEMENT AND SO ON. IN ADDITION, AFTER PROCESSING INFORMATION BECOMES KNOWLEDGE. KNOWLEDGE IS MORE IMPORTANT THAN INFORMATION AND IT HAS STRUCTURE, GROWTH AND SYSTEM. FURTHERMORE, INFORMATION CAN BE A CAPITAL RESOURCE BECAUSE COMPANIES LIKE MICROSOFT AND APPLE SPEND MILLIONS TO GET THE RIGHT INFORMATION.

DATA INTEGRITY INCLUDES ''GIGO'' (GARBAGE IN GARBAGE OUT) WHICH MEANS, INPUT AND OUTPUT OF DATA TO THE COMPUTER.

           THE ECONOMICS OF INFORMATION AND TECHNOLOGY HAS TWO BASIC ELEMENTS:

           
1. REACH: IS THE NUMBER OF PEOPLE USING THE SOURCE, SHARING INFO AND SO ON. 

           
2. RICHNESS: IS THE QUALITY AND QUANTITY OF TE INFORMATION THAT IS SHARED. 

           
AND IT HAS 3 SUB ELEMENTS:

          
1. BANDWITH

          
2. CUSTOMIZATION

         
 3. INTERACTIVITY

INFORMATION MANAGEMENT IS THE COLLECTION OF TERMS THAT ARE USED FOR MANAGING ANY KIND OF INFORMATION. IM INCLUDES THESE STEPS: CAPTURE, STORE, MANAGE, PRESERVE, DELIVER. AND IM INVOLVES PEOPLE, CONTENT, TECHNOLOGY AND INTERACTION. 

THERE ARE MANY PROBLEMS INVOLVED WITH IM FOR EXAMPLE, PROBLEMS OF SECURITY, TECHNOLOGY AND SOFTWARE, ETC. 

         

  THE FIRST WEEK WAS VERY GOOD BECAUSE I COULD REVISE MY KNOWLEDGE ABOUT COMPUTERS AND INFORMATION AND DATA. BEFORE, I TOOK COMPUTER AND INTERNET COURSE SO THE FIRST LECTURE HELPED ME TO LEARN MORE ABOUT IT.

         
IN CONCLUSION,  THIS WAS THE FIRST IT LECTURE I TOOK IN THIS SEMESTER AND I'VE LEARNT MORE THAN THAT AND I'M VERY INTERESTED IN THAT COURSE. SO GOODBYE FOR NOW AND I'LL POST AGAIN AFTER A WEEK. TAKE CARE AND SO GOODBYE!!!
