Data Communication – The Language of the Future

A career in data communications lets you work in an engineering discipline, helping computer systems and devices “talk” to each other. Networking, routers, routing protocols, and networking over the Internet are applications directly related, and of interest to, data communication majors and those considering a degree in data communication.

Data communication is sometimes considered a sub-discipline of telecommunications, computer science, IT and computer engineering, which is a primary reason why people who have education, expertise and interests in these disciplines may ultimately pursue careers in data communications. Another reason is that computer networks rely heavily on these disciplines, drawing a direct connection between the fields.

The following make students and career professionals strong candidates for careers in data communications:

Students and tech-savvy professionals who are interested in how computer networks “communicate with each other” and want to influence that communication.
Young people ready to enter the working world and seasoned professionals wanting to “re-invent” themselves who have interests in local area networks (LANS), and wide area networks (WANS).
Anyone interested in how networks are interconnected, allowing communication with a variety of different kinds of media.
Once you determine data communication is the field for you and you have an idea of what occupation within the data communications industry you may want to pursue, you can begin going after your data communication degree.
ITT Technical Institute not only offers a highly sought after degree in data communication, combining classroom study with real-world training, the institute also offers the option of getting your data communication degree online, which makes it easy for you to balance your data communication education with your work and personal life.

The data communications courses online carry the same value as those offered in our classrooms. Here, you will not only learn the fundamentals of data communications, you’ll learn and know how to apply what you’ve learned. This makes obtaining employment and following your career path much easier after graduation.

Whether you choose to get your entire data communication degree online or in the classroom, you’ll be on your way toward a rewarding career that helps computer networks communicate, which helps the business world communicate. Who knows, perhaps you can help develop a streamlined approach to network communication or maybe even help transform the entire industry and the ways in which we communicate electronically?

Characteristics of a Data Communications System

The use of data communications systems are becoming increasingly prevalent these days because of the rapidly changing way in which we do work, communicate or entertain ourselves. We use computers for most purposes these days, but are never satisfied with the available technology. One of the fastest changing fields we have today is communications, and most of the developments in information technology are therefore directly concerned with this field.

There are many ways in which data can be exchanged between two computers. The wide variety of transmission mediums available ensure that data can be exchanged with ever increasing ease. These mediums include satellites and microwaves in addition to the regular wire cable systems.

Every data communications system requires a few characteristics in order for it to be successful. The first of these characteristics is that the data should have a well defined origin and destination so that it reaches the place it is intended for. Therefore, the transmission should only be from a source device to a destination device without any interference from any other devices.

The system will be successful only if the data is delivered in an accurate manner. In fact, this is of the utmost importance. The system will need to retransmit the data if any error occurs during the process of initial transmission. Needless to say, the best systems are those that have the least errors.

The time taken to transmit data is also very relevant. The system needs to offer real-time transmission of data. This is of special importance in real time systems because the data is redundant if it delivered after a delay. These points need to be kept in mind while evaluating the effectiveness of systems for data communications. The end result is the transmission of data in a timely and reliable manner while being very cost effective.
