3. Hubs A Hub is a hardware device that connects multiple Ethernet devices together, making them act as a single network segment. The Hub contains several Ethernet ports which allows it to connect several computer to it. It works in such a way that the hub is connected to a router, and it simply broadcasts all data it receives to the computers connected to it. It is also known as: Ethernet Hub Active Hub Network Hub Content Page Next Page Previous Page

4. Bridges A Bridge device is a special hardware that filters data traffic at a network boundary. It reduces the amount of traffic on a LAN by dividing it into two segments. The Bridges inspect incoming traffic into a specific network and then decides, whether to forward it or discard it. There are different types of bridges such as: Ethernet Bridge Traditional Bridge Multi-port Bridge Content Page Next Page Previous Page

5. Switches Switches are quite similar to hubs, in terms of connecting multiple computer together on a network. There are also several differences such as: Switches boost the performance on a network, due to that way the data is transmitted between the computer in a network. Bandwidth is not sub-divided amongst the computers, for example if there is 100Mbps, and if there is two computer, each computer will have 100Mbps. A switch can be both half or full-duplex, unlike the Hubs, where there is only half-duplex. Content Page Next Page Previous Page

6. On-line & Off-line On-line and off-line have very important meanings in regards to computer technology and telecommunication. On-line is when the computer is connected to the Internet or the World Wide Web. While off-line means that the computer is not connected to the Internet or the World Wide Web.
