During the holidays I visited a local computer shop. There I noticed that all computers were networked together using a LAN and that they had a main server computer which is used not only to share resources with one another but it also ran a web server which is used for their company website. I spoke the one of the workers and they explained to me that because of new computer technology it is now much easier to repair and build computers, the old computers were very hard to assemble and installing software could become a mess, where as the new computers now days are much easier to assemble and you need not to be a computer professional to build one. Computers now days can be built by a complete novice and the help of a manual.
New technology is developed every day and at a faster pace. Computers have become extremely fast and reliable and are still becoming even faster every day. Almost every technology is now run by computers. Computers have become a necessity in life, and schooling. Our schooling system has benefited in many different ways from computers and schools have become to rely on computers. New technology will increase the speed in which we learn and discover and as new computers are made and invented, the speed in which we learn will increase and our knowledge will increase dramatically.
An information system involves the effectiveness use of people, processes, hardware, software, networks and technology to help achieve a company’s goals and objectives. An Information System involves using the above resources to transform data into information.
An information system can be manual or computerised, although as a result of the increasing speed and efficiency of computers, there are very few organisations today that would not have at least one computers in operations.
Operational systems involved in the introduction of a computer based system to the business environment.
This system processes the data produced day to day business transactions of a company or business. Transactions such as the ordering of stock, customer invoicing and billing.
An expert system is a form of Artificial Intelligence (AI) that combines the knowledge base on human reasoning and the use of extremely powerful computers. While expert systems seem to be thinking on their own they are limited by their programming. Expert systems are used in many different places an example is the fuel injection of a car.
Managing Information Systems
Managing information systems was introduced as the result of Operations Systems. A Management Information System is a computer based system that produces information for top-level, middle-level and lower-level management that is both accurate and timely.
Decision Support Systems
A Decision Support System consists of a group of people and procedures as well as a set of programmes sharing data and information. A DSS is oriented around effective decision making within the business.
Executive Information Systems
An Executive Information System supports the internal and external information requirements of top-level managers. It features the capabilities of both Decision Support Systems and Management Information Systems, hence giving far greater flexibility and support.
As the name suggests, this system involves most of the employees. An Office System includes LANs, WANs, e-mail, Internet, voice mail, word processing, database management, spreadsheets, desktop publishing, and intranets.
