Wireless repeaters
A wireless repeater receives an existing Wi-Fi signal from a router or access point and rebroadcasts it to extend the range of the network. It can bridge long distances that devices cannot connect directly or improve signals in areas with interference. However, throughput is reduced by half and interference is doubled compared to direct connection. Compatibility with older encryption and wireless standards can also impact a repeater's effectiveness. Alternatives include configuring additional routers or access points with wired backhaul, or using powerline networking devices to broadcast Wi-Fi in dead spots. Properly positioning routers and upgrading antennas can also boost a network's range without using a repeater.
Hubs vs switches vs routers
A hub, switch, and router each serve different functions in a network. A hub simply connects devices together but broadcasts all data to all ports. A switch connects devices and sends data only to the port of the intended recipient to avoid congestion. A router connects multiple networks together, both wired and wireless, and chooses the best path to send data packets between the networks.
Network devices
This document defines and compares common networking devices and terms. It discusses hubs, switches, routers, bridges, gateways, network interface cards (NICs), and modems. Hubs are basic devices that connect networked devices but do not monitor traffic or activity. Switches are more intelligent devices that can direct traffic to specific ports. Routers connect different networks and use routing tables to determine the best path for traffic. Bridges and gateways also connect different networks using different protocols.
Neetika (ppt)
Network hardware devices mediate data transfer within computer networks. Common basic networking devices include routers, bridges, switches, hubs, and repeaters. Routers connect similar networks, bridges connect similar network segments, switches manage bandwidth, hubs provide connection points, and repeaters extend network length. Hybrid devices include protocol converters, bridge routers, and digital media receivers. Other hardware like modems and network cards establish network or dial-up connections.
Internetworking
This document provides an overview of networking concepts and describes how data is exchanged between network devices. It explains that a hub operates at the physical layer, broadcasting all traffic to all connected ports so that all devices share the same bandwidth and collision domain. The document also introduces switches and routers, describing their roles in selecting the path that data travels and how they allow for separate collision domains and bandwidth allocation. It provides examples of how data is encapsulated as it passes through the different layers of the OSI model.

Network devices such as repeaters, hubs, bridges, switches, routers, and gateways are used to connect, expand, and manage network traffic. They operate at different layers of the OSI model from the physical layer to the network layer. Repeaters and hubs operate at the physical layer and broadcast traffic to all ports. Bridges segment networks at the data link layer by filtering traffic based on MAC addresses. Switches further improve segmentation by opening virtual circuits between connected devices. Routers connect multiple networks and use IP addresses to choose the best path at the network layer.

Bridges and gateways 52
This document discusses bridges and gateways. It defines a bridge as a connecting device with its own processor and memory that uses two network interface cards to connect two portions of a network at the physical and data link layers. Bridges are used to divide large networks into smaller subnetworks and connect two local area networks. The document also defines a gateway as a device that connects two networks using different protocols by operating at all seven layers of the OSI model and translating between different frame formats and protocols. Gateways are more powerful than bridges and used to connect incompatible networks.

networking devices
This document defines and describes several common networking devices and the layers in which they operate. It discusses gateways, hubs, switches, repeaters, routers, and bridges. Gateways can operate at any OSI model layer and join different network types. Hubs operate at layer 1 and broadcast traffic to all ports. Switches are more advanced than hubs, sending messages only to requesting devices. Repeaters amplify and resend weakened signals. Routers forward data between networks and are located at gateways. Bridges create separate collision domains and filter traffic by MAC address. The document also compares hubs and switches, noting switches are active devices that can send traffic selectively while hubs are passive and broadcast to all ports.
Internetworking devices
Networking devices like hubs, switches, routers, and gateways interconnect networks and manage data flow. Hubs operate at the physical layer and connect segments but do not filter traffic. Switches operate at the data link layer and can direct traffic to specific ports for better performance than hubs. Routers operate at the network layer and can connect networks across LANs, MANs, and WANs using IP addressing to route packets. Gateways can operate at multiple layers and act as connections between different network protocols or applications.

This document outlines a proposed metadata project for a school yearbook collection containing approximately 100 volumes from 9 schools in the area from 1921 to present. The collection is currently only accessible in person by appointment. The goal is to create an online digital collection to make the yearbooks more accessible and searchable. The proposed solution is to select a metadata schema, controlled vocabularies, and content management system to describe the materials. Key steps would include scanning materials, creating metadata according to the application profile, and continually analyzing and refining the metadata. This will help preserve the collection and make it more discoverable while balancing user needs, standards, and available resources.

Ethernet and Fast Ethernet standards define the physical implementation of local area networks using twisted pair cable and fiber optics. Ethernet uses CSMA/CD access method over coaxial cable or twisted pair up to 100 meters, while Fast Ethernet operates at 100 Mbps over twisted pair or fiber. Repeaters can extend the length of an Ethernet segment by regenerating the signal past the maximum segment distance.
