Business professionals can no longer count solely on IT specialists to make decisions on development, purchasing, and deployment of information systems. Regardless of their major field of expertise, those who have the proper IT knowledge and skills stand a better chance of receiving more lucrative job offers and faster promotions.
We call it the decimal counting system. However, we could also use a system consisting of only two digits, zero and one, to represent quantities. This is the binary counting system. Because computers and related devices use the binary system—a system that uses two digits—they are referred to as digital systems. However, digital systems are not used only to represent information that contains numbers, or quantities. They can also represent any information as combinations of zeroes and ones, or, more accurately, the two states that represent zeroes and ones.
Digital information consists of zeroes and ones representing two states. When you have a mechanism that can represent two states, such as electrically charged and uncharged elements, magnetized and nonmagnetized areas, light and no light, you have a way to represent the zeroes and ones. Based on such signals, information can be represented, stored, communicated, and processed digitally. That is, a digital copy is an exact copy of the original.
For example, an analog copy machine reproduces images by reflection or a similar technique.

The copy may be good, but it is never as good as the original. And as you make a copy from the copy, the quality deteriorates. When you make a copy of a digital file, such as an image file or a musical file, the system you use first captures the combinations of signals the digits, zeroes and ones that make up the file. When processed by the proper hardware and software, the digits are transformed back into the image, or music, or whatever other information you copied.
As long as your computer or other digital device can capture all the digits that make up the information, the original information can be re-created fully. Digital information is stored and communicated by way of electromagnetic signals— electricity, magnetism, and light.
These processes involve little or no moving parts. Therefore, storage, retrieval, processing, and communication of digital information are extremely fast. These capabilities—accuracy and speed—make digital systems powerful and therefore useful and important in so many fields: business, education, entertainment, and many others. Umbrella Shall I or shall I not take the umbrella? Perhaps you should buy a smart umbrella, such as the Ambient Forecasting Umbrella.
Through a radio receiver, the umbrella receives weather information from AccuWeather. A small display in the handle pulses light according to the probability of rain.
If the probability is 60 percent, the handle pulses once per second. If the probability is percent, it pulses times per minute. Source: Bermudez, A.
For instance, you probably seek information for entertainment and enlightenment by viewing television, watching movies, browsing the Internet, listening to the radio, and reading newspapers, magazines, and books. In business, however, people and organizations seek and use information mainly to make sound decisions and to solve problems—two closely related practices that form the foundation of every successful company.
What is a problem? A problem is any undesirable situation. When you are stuck in the middle of nowhere with a flat tire, you have a problem. You can solve both problems with the aid of information. In the first case, you can call a towing company, which might use a computerized tracking system to send the tow truck closest to your location; in the second case, simple accounting software can help.
An organization or individual that identifies more than one way to solve a problem or a dilemma must make a decision. This dilemma calls for decision making.
Both problem solving and decision making require information. The purpose of information systems is to support these activities. In addition to solving problems and making decisions, businesses use information systems to support daily operations, such as electronic commerce, making airline reservations, and many other activities.
As a professional, you need to understand and apply information fundamentals to succeed. Why You Should Be Well-Versed in Information Systems You might be surprised at how much information technology IT knowledge your prospective employer will expect of you when you interview for your next job, even if the position you seek is not in the IT area. Information is the lifeblood of any organization, commercial or nonprofit; it is essential to sound problem solving and decision making, upon which business success is built.
In fact, the main factor limiting the services and information that computers can provide within an organization is the budget. Because of rapid changes in technology, information systems, unlike many other business components, are quickly changing in form and content. A computer considered fast and powerful today will be an outdated machine in 18—24 months. In 12—24 months, a better program will surpass one that is considered innovative right now. The dynamic nature of information technology is like a moving target.
A professional who does not stay informed is of diminishing value to an organization. All knowledge workers—professionals, scientists, managers, and others who create new information and knowledge in their work—must be familiar with IT.
Moreover, they must know which IT is relevant for their work and what information they can obtain with a certain technology or networked resource. Professionals must at all times maintain a clear picture of their organizations and the outside business environment.
They must know what resources are available to them and to their competitors. Information technology provides excellent tools for collecting, storing, and presenting facts. But to be truly effective, those facts must be manipulated into useful information that indicates the best allocation of various resources, including personnel, time, money, equipment, and other assets. Regardless of the operations being managed, information systems ISs are important tools.

Successful professionals must know which ISs are available to their organizations and what systems might be developed in the future. Understanding what these terms mean, both generally and in the business context, is necessary if you are to use information effectively in your career.
Data vs. The word data is derived from the Latin datum, literally a given or fact, which might take the form of a number, a statement, or a picture. Data is the raw material in the production of information. Information, on the other hand, is facts or conclusions that have meaning within a context. Raw data is rarely meaningful or useful as information.
To become information, data is manipulated through tabulation, statistical analysis, or any other operation that leads to greater understanding of a situation. Assume that you work for a car manufacturer. Last year, the company introduced a new vehicle to the market. Reading through all this data would be extremely time consuming and not very helpful.
However, if the data is manipulated, it might provide highly useful information. The marketing analysts then can pass the resulting information along to the appropriate engineering or manufacturing unit. Also, the company might already have sufficient data on dealers who sold cars to the customers surveyed, the car models they sold, and the financing method for each purchase.
But with the survey results, the company can generate new information to improve its marketing. For instance, by calculating the average age and income of current buyers and categorizing them by the car they purchased, marketing executives can better target advertising to groups most likely to purchase each car.
If the majority of buyers of a particular type of car do not ask for financing, the company might wish to drop this service option for that car and divert more loan money to finance purchases of other cars.
Management Information Systems (MIS) and Business Technology
In this way, the company generates useful information from data. These calculations are processes. A process is any manipulation of data, usually with the goal of producing information. Hence, while data is essentially raw materials, information is output. Just as raw materials are processed in manufacturing to create useful end products, so raw data is processed in information systems to create useful information see Figure 1. Some processes, however, produce yet another set of data.
