CompTIA Network+ 2009: Network Protocols

This course is included in our On-demand training solution.

Overview

In the late 1970s, those people working in the computer networking field felt that there was a need for a set of standards that could be used by anyone designing and developing applications and services that would need to communicate across a network. The Open Systems Interconnection (OSI) model was designed to meet this need. The OSI model is a set of communication standards, or protocols, that enable devices and applications to communicate with each other, regardless of their origin. These protocols are sets of formal rules that govern communication and allow developers to design applications or devices that can communicate with other designer’s products without the need for direct collaboration between them. In this course, the OSI model is explained as is a wide range of protocols, including those that are part of the TCP/IP suite of protocols. The protocols are the foundation of networking and without them there would be no network and no Internet.
This course maps to CompTIA’s Network+ (2009) exam objective explain the function of each layer of the OSI model and for explaining the function of common networking protocols and identifying commonly used TCP and UDP default ports.

Target Audience

The audience for CompTIA Network+ 2009 training will comprise IT personnel with at least 9 months IT networking experience. Good computer literacy along with a sound technical acumen should be present. Students looking to acquire job skills, and to be trained specifically to pass the associated CompTIA Network+ (2009 Edition) certification exam will want to study this learning path.

Prerequisites

CompTIA’s A+ credential is a recommended, although not mandatory, prerequisite.

Expected Duration

180 min.
