Naturally, computer networks are expected to perform well, and it's vital to understand the factors that can impact network performance. A network's bandwidth is the number of bits that can be transmitted over the network in a certain period of time. Latency is how long it takes a message to travel from one end of a network to the other and is measured in time.
A Systems Approach. Computer Networks: The book encourages readers to think, through a number of perspectives, about how a network can fit into a larger, complex system of interaction.

Even a relatively Troubles continue for Huawei as new bans and government reports put security into question, but the company is attempting to We believe that the text to support this effort needs to provide balance between discourse and technical depth, whi le taking an historic, developmental approach.
We should not assume that students in these classes cannot manage technical detail; neither should we expect them to become engineers. Yet a text without technological underpinning provides explanations too vague to be sufficiently meaningful.
The business student with no prior background in the subject will not have the technical context within which to comprehend and assimilate what appear to be high-level concepts, whereas the more experienced student or professional is not provided with the possibility of deeper insight.
In our courses. This becomes clear later on when a problem is confronted, or when the student is questioned a year. We have developed a pedagogy that. Accordingly, we searched for texts supporting that pedagogy. What we found was a variety of approaches: Texts that combine basics and appl ications in each chapter, an organization that forces piecemenl treat ment of the foundation material.
In our experience, that approach doesn' t work wel l. Yet they often have little understanding of what is going on in the networks they are using. Getting students to grasp the meaning of an architectural model such as OS! How, for example, can a description of the data link layer's functionality be meaningful under this scenario?
The upshot is that the student is left wi thout much con text or basis to value, let alone really comprehend, the subject. Technologies do not arise spontaneously.
Instead, each builds upon what preceded it, guided, prodded, and molded by performance necessity, business concerns, political issues, and engineeri ng capabilities. In our text, we take the same view, noting how the tield developed in response to a variety of pressures and, thereby, how each step led to the next. At the same time. This histori cal developmental approach leads to a broad understanding of the field that also provides the basis for further study, whether in the classroom or on one's own.
We believe so strongly in this approach that we have explored certain topics more than might at fi rst glance seem warranted.
