Some of them are the switches, routers, firewall etc. Recognize the purpose and functions of various network devices such as routers, switches, bridges, and hubs. ... a special connection is opened up between two network devices, and the channel remains open to transmit data until it is closed. Select the components required to meet a given network specification. Some examples of end devices are: Computers ,laptops, file servers, web servers. Let us explore some of these devices in greater detail. These devices form the interface between the human network and the underlying communication network. A switch forwards data to its destination by using the MAC address embedded in each packet. Comparing and contrasting Network devices, their features and Functions. Gateways. A hub does not perform any tasks besides signal regeneration. The network devices that people are most familiar with are called end devices. This computer functions effectively as a NAT Router, and must be left switched on for the other computers to access the Internet. Devices Objectives This chapter covers the following CompTIA-specified objectives for the “Media and Topologies” and “Protocols and Standards” sections of the Network+ exam: 1.6 Identify the purpose, features, and functions of the following network components:. Wireless access point transmits the signal which allows the client to connect to the access point and to the route traffic between the wireless and wired interface. Routers. With the help of dynamic routing protocols, routers will let other network devices know about not only the topology of the network but also about network changes. Switch Connects devices on a twisted-pair network. One should know about all of them to get some good insights about the network devices. Network Infrastructure devices are the physical components used to build the computer network.Depending on the size of the enterprise network, different models of different capacity and quantity of network infrastructure devices are used in the network. Hubs. Learn how the most common types of network protocols works in computer network. Without network protocols, the modern internet would cease to exist. CSU/DSU. Device Function/Purpose Key Points Hub Connects devices on a twisted-pair network. Understanding these basic network protocols with functions will help you in managing network effectively. This configuration is not normally used anymore. Switches. General Networking Physical Components and Functions. There are many network devices which are being used these days to get connected to the internet. Network devices may be inter-network or intra-network. Bridge Divides networks to reduce overall network traffic. Features and functions of Wireless access points Bridges. Identify the appropriate media, cables, ports, and connectors to connect Cisco network devices to other network devices … Modem. In a building if there are devices which uses network, then the device can use the internet wireless without any cables connections. Some devices are installed on the device, like NIC card or RJ45 connector, whereas some are part of the network, like router, switch, etc. The basic routing function can be split into two areas; one is to build a map of the network and for that routers typically use either static routing or dynamic routing protocols.
