CompTIA Network (Exam N10-007) Lesson Introduction The CompTIA® Network+® certification covers a wide range of knowledge and skills that apply to different networking job roles. Any networking jo... b role requires a fundamental knowledge of network terminology, components, standards, types, and configurations. In this lesson, you will identify the basic concepts of networking theory. With a background in CompTIA Network+ information and skills, your networking career can move in many directions. Whether you are a network support technician, installer, or administrator, knowledge of basic networking theory provides the necessary foundation needed for learning more advanced networking concepts. A good grasp of fundamental networking theory will help you succeed in any network-related job role. Lesson Objectives In this lesson, you will: • Describe the primary types of networks. • Identify the layers and purpose of the OSI model. • Identify the primary data transmission methods on a network. 1 TOPIC A Network Types This lesson introduces the primary elements of network theory. In the information technology industry, there is a set of common terminology used to discuss network theory. In this topic, you will define common terms used in networking. Networking, like any other technical discipline, has a language of its own. Part of mastering the technology involves familiarity with the language you use to describe that technology. With so many technical terms involved in the field of networking, the information and definitions in this topic will help you get familiar with these terms and the context in which they are used in networking. Network Components There are several common components that make up a network, each of which performs a specific task. Network Component Description Devices Hardware such as computers, tablets, cell phones, servers, printers, fax machines, switches, and routers. Physical media Media that connects devices to a network and transmits data between the devices. Network adapters Hardware that translates data between the network and a device. Network operating systems Software that controls network traffic and access to common network resources. Nodes Any device or computer that can connect to a network and generate, process, or transfer data. Servers A network computer or process that shares resources with and responds to requests from computers, devices, and other servers on the network. Network Segments A subdivision of a network that links a number of devices or serves as a connection between two nodes. Backbone A very-high-speed transmission path that carries the majority of network data. It connects either small networks into a larger structure or server nodes to a network where the majority of client devices are attached. Client A computer or process running on a device that initiates a connection to a server. The term "client" most often refers to workstation or desktop computers employed by end users. Any device on the network can function as a client when it uses other computers' resources, such as a Windows Server computer accessing resources on another server. Host A network-attached computer that communicates with hosts and other devices to provide data or services. [Show More]
