ENVS 1200 Lecture 21 Notes – Computer Peripherals
Introduction
• As an alternative point of view, the network represents an essential component of
modern technology infrastructure, offering the ability to interconnect computers,
storage devices, computer peripherals, cellular telephones, personal digital assistants,
video and audio devices, and, most importantly, other networks, to share resources and
services, to share and exchange data and knowledge, and even to communicate and
socialize.
• From this perspective, a computer is simply another device connected to the network.
• In this view, for example, a computer connected to a network might be masquerading as
a telephone or a display device for videos or a source of music, using the network as the
medium of communication.
• Both views are important and useful at different times.
• Often, viewing a network connection as an I/O device is a very useful approach to
system design and problem solving
• Particularly if your goal as a user is simply to obtain data from a database stored on a
server somewhere on a particular network
• On the other hand, if your job is to design and implement, or maintain and administer a
network
• You must thoroughly understand the design issues from the perspective of the
technology and infrastructure of the network itself.
• We are interested in the latter ie. We ill open the cloud, so to speak, and study
the basic concepts and infrastructure of network technology.
• As has been the case throughout this text, our primary focus is on broad fundamental
concepts
• Rather than the specifications and details of a particular type of network or
methodology
• In a field as fast-changing as network technology, specifications can and will change
