An Introduction to Computer Networks 1 An Overview of Networks. 13 of selected important network applications, or the basics of network. working, the computer network will more likely be successful in the company. Lauren has decided to review basic network concepts with her coworkers as. Introduction. -A network can be defined as a group of computers and other devices connected in some ways so as to be able to exchange data. -Each of the .

Terrestrial microwaves are in the low gigahertz range, which limits all communications to line-of-sight. These Earth-orbiting systems are capable of receiving and relaying voice, data, and TV signals. Cellular and PCS systems use several radio communications technologies. The systems divide the region covered into multiple geographic areas. Each area has a low-power transmitter or radio relay antenna device to relay calls from one area to the next area.

It's too simplistic to view a computer network as simply delivering packets among a collection of computers, however. A network should be thought of as the way to deliver a set of applications distributed over those computers. Success includes both understanding the applications' requirements and recognizing the limitations of the underlying technology.

The challenge is to fill the gap between what the application needs and what the technology can provide. Networks do not remain fixed and must be able to evolve to accommodate technological changes, and networking and IT professionals must be able to manage them. Designing a network to meet those requirements isn't easy. The most basic requirements for a network are that they must provide general, cost-effective, fair and robust connectivity among a large number of computers.

Network architectures are general blueprints that guide the design and implementation of your network.

The idea of abstraction, which hides your networking details behind a well-defined interface. The idea of abstraction is to make a model that can capture an important aspect of the system, but the challenge is to identify abstractions that simultaneously provide a service that proves useful in a large number of situations.

Abstractions naturally lead to layering. The idea is that you start with the services the underlying hardware offers, then add a sequence of layers, each of which provides a higher level of service. Layering helps IT professionals build a network into more manageable components.

One of the things that has made the Internet such a success is the fact that software running in general-purpose computers provides so much of its functionality, which means new functionality can be added easily. As a result, new applications and services can deployed in a heartbeat. Knowing how to deploy network software is an essential part of understanding computer networks. Specific instructions and visual representations for both the client and the server can be found in the networking PDF.

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.
