A network hub is a device that allows multiple computers to communicate with each other over a network. Image: Hub and wireless hub network icons. In the Open Systems Interconnection (OSI) model, network hubs operate at the physical layer (layer 1). A hub acts like a repeater: all data that arrives to one port is sent to all other ports (without looking at IP address for the data's destination). Compared to a standard switch, the hub is slower as it can send or receive information just not at the same time, but typically costs more than a hub. Hubs and switches serve as a central connection for all of your network equipment and handles a data type known as frames. Definition: A connectivity device to which network cables are attached to form a network segment. Passing it along to every port ensures that it will reach its intended destination.

The hub contains multiple ports. The purpose of a hub is to form a single network segment on which all devices can communicate directly with each other. Devices on a hub function as a network segment and share a collision domain. When a hub receives a packet of data (an Ethernet frame ) at one of its ports from a network device, it transmits (repeats) the packet to all of its ports to all of the other network devices. Huge List Of Texting and Online Chat Abbreviations, How To Create A Desktop Shortcut To A Website. A third type of hub, called a switching hub, actually reads the destination address of each packet and then forwards the packet to the correct port. Hubs can be used as a standalone device or connected to compatible hubs and switches to form a larger network. They're often made of plastic and receive power from an ordinary wall outlet. This differs from a switch environment, where each port is allotted a dedicated amount of bandwidth. The most commonly used hub is an ethernet hub. Hubs were available in different shapes and different numbers of ports. Thus, when two devices connected to a network hub transmit data simultaneously, the packets will collide, causing network performance problems. A Hub is a networking device that allows one to connect multiple PCs to a single network. It is one such device like others which are used in the network like a switch and router.

Dual-speed hubs internally consist of two hubs with a bridge between them. Hubs connect segments of a LAN. Vendors now offer UPSes with functions that help regulate voltage and maintain battery health. Hubs typically do not filter data, but instead retransmit incoming data packets or frames to all parts. However, when a data frame arrives at any port of a network switch, it examines the destination address and sends the frame to the corresponding device(s). This places a lot of traffic on the network and can lead to poor network response times. Webopedia is an online dictionary and Internet search engine for information technology and computing definitions. Creating a desktop... Microsoft Windows is a family of operating systems.
