networking devices and their functions ppt

Network devices are components used to connect computers or other electronic devices together so that they can share files or resources like printers or fax machines. Functions of a Network Switch A switch is a device that is used at the Access or OSI Layer 2; a switch can be used to connect multiple hosts (PCs) to the network. Network devices may be inter-network or intra-network. OSI stands for Open System Interconnection is a reference model that describes how information from a software application in one computer moves through a physical medium to the software application in another computer. A hub does not perform any tasks besides signal regeneration. A communication device is a hardware device capable of transmitting an analog or digital signal over the telephone, other communication wire, or wirelessly.. A classic example of a communication device is a computer modem, which converts a computer's digital information to an analog signal for transmission over a telephone line. Individuals, professionals and academics have also learned to rely on computer networks for capabilities such as electronic mail and access to remote databases for … OSI Model. Switches, routers, and wireless access points are the essential networking basics. 1. Describe the purpose and functions of various network devices. The App Service Environment, which deploys into your VNet and supports Isolated pricing plan apps. Exam: Cisco 200-120 - Interconnecting Cisco Networking Devices: Accelerated (CCNAX) As your network grows, it needs to be broken into smaller networks or network segments to ensure better performance of the network. Wireless access points (WAPs) Modems. Combined software packages containing monitoring tools can cover all of these elements of company infrastructure. The primary purpose of a Hub is to regenerate a signal. While a wired or wireless link is technological in an AP, it usually means a wireless device. The “loopback” device, which is a virtual interface to the local machine, is an example of this. The functions of a router, switch and hub and are all different, even if at times they are integrated into a single device. This tutorial explains computer peripheral devices and their function in details with examples. Some devices are installed on the device, like NIC card or RJ45 connector, whereas some are part of the network, like router, switch, etc. What is Bridge in Networking. Gateways. A network topology refers to the way in which nodes in a network are connected to one another. This enables you to use multiple services in a network environment while minimizing the influence that the services have on each other. Within the next 3 years, 90 percent of IT organizations may support corporate applications on personal mobile devices. Switch Connects devices on a twisted-pair network. Ethernet Tutorial – Part I: Networking Basics Computer networking has become an integral part of business today. Modem Also, you will learn about the most common types of protocols used by the network models while communicating one system with another. CSU/DSU. 3. You will also need to configure their connections to keep network traffic private. A wide range of devices are used in modern networking. Network interface cards (NICs), ISDN adapters, and system area network cards. Network protocols are the languages and rules used during communication in a computer network. Firstly, what are Network Protocols? Routers. Hub is a device which is used during the Physical layer of the OSI Model, which is indeed the first layer. The network structure defines how they communicate. Before going straight to the table. Through them, devices connected to your network can communicate with one another and with other networks, like the Internet. Cybercriminals are increasingly targeting mobile devices and apps. Of course, you need to control which devices can access your network. Learn how computer peripheral devices (such as RAM, ROM, processor, input and out device, motherboard and storage device) work with functions and specifications. Access Point. LAN: LAN stands for “local area network”. 40 Network Protocol Names And Port Numbers With Their Transport Protocols And Meanings tabulated by Precious Ocansey (HND, Network Engineer). Network Layer – The network layer is responsible for creating routing table, and based on routing table, forwarding of the input request. A network interface may be associated with a physical device, or it may be a representation of a virtual interface. Switches, routers, and wireless access points perform very different functions in a network… Their stiffness caused network administrators difficulty when installing and maintaining thinnet and thicknet. A hub connects two or more computers together (like switch in diagram above). The following is a brief introduction to common network components and devices. Bridge basically works in a bus topology.As mentioned in below example, In bus topology the time PC 1 wants to send data to PC 8, it broadcast the data to all the connected devices in a network and like this, it creates lots of traffic. Routers and switches are both computer networking devices that allow one or more computers to be connected to other computers, networked devices, or to other networks.. Definition: A connectivity device to which network cables are attached to form a network segment. Devices used to setup a Local Area Network (LAN) are the most common type of network devices used by the public. A SOHO router is a broadband router built and marketed for small offices and home offices. The Internet Protocol (IP) is the principal communications protocol in the Internet protocol suite for relaying datagrams across network boundaries. Computing devices are the electronic devices which take inputs, process the inputs and then calculate results from the inputs. Zigbee is an IEEE 802.15.4-based specification for a suite of high-level communication protocols used to create personal area networks with small, low-power digital radios, such as for home automation, medical device data collection, and other low-power low-bandwidth needs, designed for small scale projects which need wireless connection.. A collision occurs when two devices within the same domain attempt to send data at the exact same time. Here we tell you about the same. Unlike a hub, a switch forwards a message to a specific host. Switches.

Its routing function enables internetworking, and essentially establishes the Internet.. IP has the task of delivering packets from the source host to the destination host solely based on the IP addresses in the packet headers. Virtual network integration allows your function app to access resources inside a virtual network. The router can identify packets by their IP addresses, port numbers, etc., and transmit the packets such that each type of traffic remains below its specified limit. Hubs typically do not filter data, but instead retransmit incoming data packets or frames to all parts. At this point, you can see that routers can connect different types of networks together and send data between them. A switch forwards data to its destination by using the MAC address embedded in each packet. If this occurs, the switch drops both packets, and the end devices are forced to retransmit. Or in simple words, these are basically the mathematical devices which… Some of the Devices used in Network Layer are, Routers: A router is a switch like device that routes/forwards data packets based on their IP addresses. Since the workload for these types of businesses is primarily on the internet, they require a local area network (LAN), which means their network hardware is structured specifically for that purpose. Platform security ensures that each device is available to perform its intended function and doesn't become the network's single point of failure. A SOHO network can be a mixed network of wired and wireless computers. A collision domain is a Layer 2 network boundary where devices can send a broadcast frame and reach all devices within said segment. network management system: A network management system (NMS) is a set of hardware and/or software tools that allow an IT professional to supervise the individual components of a network within a larger network management framework. Types of Network Protocols and Their Uses - In this chapter, you can find a detailed description of various useful protocols and their types. With a keyboard, it is possible to input text and numbers, as well as execute a number of actions, such as printing, taking a screenshot or moving around a Web page. Let us explore some of these devices in greater detail. So, from overcoming this problem we are using a networking device bridge.
