Target Audience Anyone desires a practical, technical introduction to the field of networking. High-school, community college, and lifelong-learning students interested in careers as network technicians, network engineers, network administrators, and network help-desk staff.
In addition, instruction and training are provided in the proper care, maintenance, and use of networking software, tools, and equipment and all local, state, and federal safety, building, and environmental codes and regulations.
Course Objectives The CCNA certification indicates knowledge of networking for the small-office, home-office SOHO market and the ability to work in small businesses or organizations whose networks have fewer than nodes.
Approximately 35 hours will be designated to lab activities and 35 hours on curriculum content. A case study on structured cabling is required, but format and timing are determined by the Local Academy.

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. Network performance is measured by bandwidth and latency. 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.

Computer Networks: A Systems Approach, Fifth Edition, teaches the key principles of computer networks, using the Internet as a primary example to explain protocols and networking technologies. The book encourages readers to think, through a number of perspectives, about how a network can fit into a larger, complex system of interaction. His research focuses on the design and implementation of networked systems.
