Introduction

Information Technology Management Since the beginning of time, humans have had the need to communicate with each other. Cavemen gradually learned to communicate through making audible grunts and making drawings in the sand. Indians were able to communicate over long distances by creating plumes of smoke with a fire and a blanket. In the 1800's people entertained the idea of sending letters using horseback mail carriers. Early settlers could wait weeks or even months to receive information that is no longer accurate. The invention of the telegraph saved time by allowing people to send chunks of information back and forth to each other over a communications line. It was not until the invention of the telephone that people could actually have a real-time conversation over a long distance. In the modern age, technological advancements have created many ways that information can be sent and received. To name a few, satellites, cellular phones, pagers, computers, and high speed networks have changed the way the world does business. Information is known as the knowledge derived from data that has been transformed into something meaningful and useful. Managing data is subjected to a value-added process that produces meaningful information for decision making. The knowledge that individuals gain, whether it be concepts, tools, or categories, are used to create, store, apply and share information with others. There are many forms of knowledge, ranging from books to the internet. Business organizations process and store large amounts of data that is then translated into useful information for employees to use and make business decisions. ...read more.

They rely on a series of routers, network switches and miles of communication cables that link PC's, Servers, and mainframe computers together to form a data communication network. The internet consists of a rapidly growing network of thousands of computers, educational, corporate, private, and research networks around the globe. The internet has had a Information Technology Management 5 dramatic impact on many organizational strategies, processes and functions around the world. The Internet is often referred to as the Information Superhighway. Any person with a computer and a network card and a modem can access the internet. Internet access makes possible, the four basic functions: e-mail, telnet, FTP, and the World Wide Web. E-mail allows users to write letters and send memos to anyone who has an e-mail account. Telnet allows users to access remote systems to configure and interact with them. File transfer protocol allows users to migrate files and data from one computer to another. User can download everything from small documents to large programs. The World Wide Web allows users to input and access video, text, sound, and images over the internet using a web browser. Users can also use a web search tool called a search engine, which allows a user to find exactly what he or she is looking for on the internet. An extranet is similar to the intranet, however, it is not to be accessed by the general public. The extranet is a wide area network that connects members of an organization, suppliers, and customers together over a network to meet a business need. ...read more.

Conclusion

Information Technology Management 8 The implementations of such information systems have dramatically changed the world of business and management. Companies have formed a dependency on such systems to the point in which they cannot compete without them. I see the success of an information system to be directly related to having quality components and excellent systems management. Disaster recovery procedures must be in place along with having the right resources and documentation in the case of such an event. Backup procedures and redundancy is the key to having a failsafe information system. People take these systems for granted when being used on a day to day basis, and do not understand the value until the system is inaccessible. There is endless work involved in creating, configuring, securing, and maintaining these systems and they are constantly being changed and updated. A knowledgeable support staff is also crucial to the success of an information system. Keeping up with the latest and greatest technology systems in the business world can prove to be quite costly. I think that the cost associated with the support and maintenance of modern information system is well worth the money. Costs are being reduced in other areas by the simplification of every day tasks by these information systems. I think that the internet along with company intranets and extranets are the best way for companies to share information, maximize productivity, and deliver results. While there are some issues pertaining to security and privacy, new technologies and the appropriate technology management principles will provide innovative ways to resolve these and other problems as they arise ...read more.
