Chapter 1 - Summary of important concepts
What is an Information System?
Computers are changing every aspect of our lives from entertainment to shopping, from the work we do and where we do it, to how we communicate with friends and relatives. This section discusses the components of an information activities i.e. input (captures or collects raw data from within the organization or from its external environment). Processing (converts this raw input into meaningful form). Output (transfers the processed information to the people who will use it or to the activities for which it will be used). Plus feedback processes. The most important process is the feedback process; unfortunately, it’s the one most often overlooked. The hardware (input and output) and the software (processing) receive the most attention.

Figure 1-4 shows how using feedback completes the information processing loop. To be a good information systems manager, however, you must bring into that loop far more than just computer data. In a typical online ticket-selling Website, the raw input consist of order data for tickets, such as the purchaser’s name, address, credit card number, number of tickets ordered, and the date the game. Computers store these data and process them to calculate order totals, to track tickets ordered, and to send requests for payment to credit card companies. The output consists of tickets to print out, receipts for orders, and reports on online ticket orders. The system provides meaningful information, such as the number of tickets sold for a particular game, the total number of tickets sold each year, and frequent customers.
COMPLEMENTARY ASSETS: ORGANIZATIONAL CAPITAL AND THE RIGHT BUSINESS MODEL
Once technology was considered “too technical” for the rest of us to understand. Computers were relegated to the back room with a few technicians running around in white coats. No one else
