Over the past several decades, as data processing capability has been introduced into the office,
data communications products and services have gradually assumed increasing importance.
Now, technological developments and the widespread acceptance of standards are
transforming the ways in which information is used to support the business function. In addition
to the traditional communications requirements for voice and data (meaning text and
numerical data), there is now the need to deal with pictorial images and video information.
These four types of information (voice, data, image, and video) are essential to the survival
of any business in today’s competitive international environment.What is needed in a business
data communications book is a treatment not just of data communications but also of
information communications for the business environment.
Information communications and computer networking have become essential to the
functioning of today’s businesses, large and small. Furthermore, they have become a major
and growing cost to organizations. Management and staff need a thorough understanding of
information communications in order to assess needs; plan for the introduction of products,
services, and systems; and manage the systems and technical personnel that operate them.
This understanding must comprise the following:
• Technology: The underlying technology of information communications facilities,
networking systems, and communications software
• Architecture: The way in which hardware, software, and services can be organized to
provide computer and terminal interconnection
• Applications: How information communications and networking systems can meet
the requirements of today’s businesses
