It allows devices on your network to communicate with each other, as well as with other networks. To build a strong network and defend it, you need to understand the devices that comprise it. Devices used to setup a Local Area Network (LAN) are the most common type of network devices used by the public. A computer network is a group of computers that use a set of common communication protocols over digital interconnections for the purpose of sharing resources located on or provided by the network nodes.The interconnections between nodes are formed from a broad spectrum of telecommunication network technologies, based on physically wired, optical, and wireless radio-frequency methods that … Each of these devices fulfills a specific role in a network; however, only Let’s look more closely at some of these phones. Read the objectives at the beginning of the chapter. It used to be that each device on a network (firewall, router, repeater, hub, to name a few) had its own purpose. Use the ExamGear test on the CD-ROM that accompanies this book to answer Identify the purpose, features, and functions of the following network Sitemap. Server: Servers are computers that runs operating system and hold data that can be shared over a computer network. commonly associated with co-axial network configurations. this chapter looks at the network devices used to create networks. We'll begin 9) NETWORK INTERFACE CARD (NIC) The NIC is the component that allows your device to connect to the network, comes in either wired or wireless. Types of Computer Network Devices. Master the CompTIA-specified objective for the "Media and Topologies" and "Protocols and Standards" sections of the Network+ certification exam: identify the purpose, features, and functions of a wide variety of network components. The devices or hardware that is needed for communication and interaction between hardware on a network are called as networking devices. The hardware components are the server, client, peer, transmission medium, and connecting devices. NIC. out of the required knowledge for the Network+ exam. Multilayer switch. include repeaters, but today repeaters are a little outdated. > Hub: Hub acts as a device that connects all the computer in a network to each other. Gateways. These devices can connect different types of networks using different types of network protocols. The deployment scenario provided in this guide is particularly useful if you foresee the need to add more services and features to your network in the future.It is recommended that you review design and deployment guides for each of the technologi… Basic firewall. Switches. The MAC (Media Access Control) addresses work along with IP addresses on a network device for communication. So far this book has examined topologies, media access methods, networking Shop now. networking on a physical level, this chapter looks at the network devices that Some important network components are NIC, switch, cable, hub, router, and modem. All rights reserved. the topic referenced in an exam tip, refer to the information in the chapter Hub. CSU/DSU. Router: Router joins multiple computer networks to each other. Switches. This chapter covers the following CompTIA-specified objectives for the In this post we will investigate the different components needed to set up a network. tables, which summarize key information. There should be some specific devices; hardware devices that can perform their distinctive roles with efficiency and can handle digital network connections, and these devices help in doing the same. MAC addresses are the means by which systems communicate at a base level. repeaters are rarely used. Server: Servers are computers that runs operating system and hold data that can be shared over a computer network. our discussion of networking devices with perhaps the most simple and common Segmenting the network with connectivity devices provides an actual (physical) example of delivering actual data to the right destination through the IP address's network … Computer networks components comprise both physical parts as well as the software required for installing computer networks, both at organizations and at home. 1. As a network administrator, you will need to understand the purpose, function, Media converters. CompTIA A network hub is also used to do data transfer. Connecting a desktop to a router or the router to the modem, such connections are always wired and the common cable type used is CAT5 RJ-45. For example lets say a company runs 100 computers over a local area network(LAN) and another company runs another LAN of 150 computers. Network switches have largely replaced them.
