 Good morning student. I am Dr. Sachin R. Gengze, Professor and Head, Department of Electronics Engineering at Vulture Institute of Technology, Seoul. In today's session, we are going to discuss about what are the features of a typical information system. The learning outcome of today's sessions are like this. At the end of this video, when you watch this video, you are able to explain a process flow in an information system. You can also explain the components of an information system and you can talk about or you can evaluate, you can discuss about the major capabilities of information system. So, we already know what is an information system. I will just, I will just give you a, I will just repeat the definition of an information system. As we know, the information system is a one which can collect, process, store, analyze and disseminate information for a specific purpose. As I said, take an example of banking. It can collect, it can collect the information. It can process the information. When we are withdrawing the money from our account, then our, our account balance should be, should be deducted by, by that much of amount. Then it is a processing. Then my banking account information is stored. There can be an analysis also. For example, the bank manager can look into the different customers and can find out who are the valuable customers and who are, who are the customer which, which may, which are not that valuable. Then this information can be disseminated. This information can be disseminated internally into the bank with the managers and clerks or this information can also be disseminated with the customer. For example, when I am withdrawing money, I get an SMS from the bank. So, that is nothing but the dissemination of information. So, the information system basically collects, process, store, analyze and disseminate information for a specific purpose. So, the purpose is important. For example, the system which I am talking about is a banking system or a saving bank account, my saving bank account. So, that is a specific purpose. When we are talking about the information system, we are, we are definitely talking about a computer-based information system and not the manual information system which uses the different digital technology. It uses laptops. It uses computer. It uses your smartphones. It uses all the communication media and, and then it is called as a computer-based or a digital information system. Information system basically consists of many small subsystems and then these small subsystems or components are connected through wired or wireless network. So, that is a typical flow in, in an information system. Basically, information system, why we require an information system? Because we have some input, we have some business problem to be solved. For example, I have to maintain or the bank has to maintain my saving bank account and for that it requires an information system. So, what is the input for the information system? The information, the input for the information system is the business problem which can be solved by the people using programs, equipment and the storage and then it generates the output and the output is nothing but the solution to the problem. So, if you look at the input, the input consists of the data. It consists of the information. It consists of the instructions and opportunities. So, all this input is being processed by the information system. As I say, the people are using different programs and different equipment. It may be laptops, it may be your hand, it may be your smartphones, it may be your desktop computer and then there can be a storage in which all this storage processed data is stored, the information is stored and then there can be an output. So, after processing we can get output. What can be output? The output can be different types of the reports. It can be graphs, it can be calculation, it can be recommendations and all that. So, that is called as an output. So, basically the business problems are solved. The business problems are processed to generate the required output. Now, there can be two types of the information system, one in which the human intervention may be required, one in which the human intervention may not be required. So, depending upon what kind of business problem we are going to solve, there can be human intervention or there cannot be a human intervention. Then once we understand what is the process flow of a typical information system, the next part is of course, what are the different components or the building blocks of the information system. So, as you can see the information system consists of mainly five or six part. Definitely as I say this is the information system we are talking about is a digital information system and for that we require the hardware. The hardware may be your desktop computer, it may be laptop computer, it may be smartphone, it may be BDA, it may be servers, all that will come under the banner of hardware. Definitely the hardware, only hardware is of no use, we require software, we require program and for processing as we know the information system has to do different tasks like accepting the data, the processing data, analyzing data, degenerating the information, storing the data and information, designating information for doing all this we require software. So, all that will come under the banner of software. Then there is of course, this hardware and software together will generate that or there can be input also and that is what is called as the data and information. Then there are certain procedures and certain processes which need to be followed in an information system and that will come under the banner of procedures. Most importantly as we say that information system consists of different component, different building blocks which are connected to each other, they may exist in a same campus, they may exist all over the world, they are talking to each other and these components, these subsystems are connected using the networking and communication device and as we know internet is one of the major networking that we are using for this information system. Then there is something called as a viewer interface, ultimately the information system are made to help the people and then the people has to interact with the information system and that interaction is going to take with what is called as the human or user interface. So, it consists of the different GUIs, different types of the GUIs, the GUI which is required for desktop or for laptop or mobile view and all that. So, all that is called as the user interface and mostly the basic there should be a purpose of desiring the information system. The information system should have a particular application, a particular purpose and that is also taken as the one of the building block of the information system. So, as we can see over this is very important to understand that the typical information system consists of a hardware, a software, then there has to be data information, there has to be some procedure to be followed, all these are talking to each other using networking and communication and in some of the cases or in most of the cases the information system is meant for the human or for the people, for the benefit of the people, for the assistance of the people and it must have the human interface or the user interface and then there has to be purpose or application for which this information system is being designed. We, you are requested to pause the video here for some time and just think about what are the different building blocks of a typical information system, try to name them and what is the purpose of each of the building block and then you can take, you can explain one of the example where in how these different building blocks are being utilized in that particular information system. So, I hope you are ready with your answer and you and you are able to describe a typical application of information system and what are the different building blocks of this information system and how they contribute into the application of information system. After that we will come to the last part of the session and which is about the major capabilities of information system. As I said the concept of information system was was into existence even before the digital technology people were maintaining the manual information system, book keeping and lasers. As we have moved from that manual information system to the digital information system, what are the major capabilities of this information system, how they are going to help us, how they are going to make our problems or how they are making to solve the problem easier that is what is called as the major capabilities of the information system. So, let us understand what are the what are these capabilities. First they perform high speed high volume computation as we know computers are today's computers are very fast in processing the data and that is why as we are using this the computers for processing our data the information system itself is a very high speed and high volume. We know that the computers and the servers are equipped with a high volume of data, high volume of storage capability and that is why the information system can also store very high volume of data and information. They provide fast accurate reliable communication between and within organization anytime any place. As I said the computers are very fast our information systems are very fast as soon as I withdraw my money from the ATM immediately I get a message then it is very accurate. As this information systems are processed by the computer we know that there cannot be any mistakes done by the computer there can be bugs but there cannot be any mistakes and then that is why this as long as there are no bugs exist these information systems are very accurate and reliable. And then this information system can communicate within the organization maybe in a banking there can be different section and then there can be communication between these section using the information system or it is between the communication maybe between the bank and the customer. So that is the all they are all this type of communication the internal communication and external communication is possible with the information system and anytime any place. Previously the bank was only open from 10 in the morning up to 3 o'clock in the afternoon but now if I have an ATM card I do not need to go to a bank I can I can even I can withdraw my money at 12 o'clock at the night I can go to any ATM at any place my bank account may be with a particular branch but if I have an ATM card or if I have a debit card or a credit card I can go to any of the ATM center across the globe and I can withdraw the money at any time at any place. So this capability is possible only because of the information system then the information system allowed to store huge amount of easy to access huge amount of data and information. So as I say the information systems are backed up by the computer technology digital technology which are now possible with which which is now possible to provide huge server with a huge capability of a storage of the data and that is why it is it does not matter for example as I say that the Facebook is storing huge amount people are uploading their posts the people are uploading the audios and videos and photographs and everything on the Facebook and that is why the the amount of data is large or huge but at the same time that data can be accessed I can just go and Facebook and see that what is the post I have posted one year back and within few second I get that or within fraction of the second I get that answer. So although the data is large the processing of the data is fast and the retrieval of the data is also fast the information system allow me quick and easy access of the information anytime anywhere on multiple type of the devices I can access my banking using an internet bank internet back internet banking from my mobile phone or my desktop computer or I can walk through I can walk through into an ATM center and can do that or if if I still believe in the traditional banking I can go to personally to a bank and I can do that. So it it means that it is a very easy quick access of information anytime anywhere on multiple devices the devices are all digital they are all connected they are all smart and I can use them then the information system allow you to present with the graphs and chart which is very important for analysis or rather understanding or interpreting the information if the information is only presented in a tabular format then it will be difficult but if the table is converted into a graph then I can I can understand that graph I can I can get whatever I want out of that graph very easily and that is also one of the major capability of the information and lastly the information system allow you to facilitate work in a hazardous environment. So where it is not possible to depute the human I think that there we can we can put the information system or we and then that information system can work can collect the data can process the data. So these are the major capabilities of the information system and that is why as we know the information systems are becoming more and more popular in today's world. With that we come to the end of this session in which we discussed about the different features and capabilities of the information system. The references to be followed for this session it include two of the books the first book is information technology for management by Terman and Volvino and then it is from the Wiley student edition and it's a second edition and the second book is from Sengage Learning and it and and its name is information system and it's by Stair and Reynolds. Thank you student for patient
