Where there is a need for a great deal of analysis of network performance and security, switches may be connected between WAN routers as places for analytic modules. Some vendors provide firewall, [21] [22] network intrusion detection, [23] and performance analysis modules that can plug into switch ports. Some of these functions may be on ...
4-port 10BASE-T Ethernet hub with selectable MDI-X/MDI port 8-port Ethernet hub with one 10BASE2 connector and eight 10BASE-T ports. An Ethernet hub, active hub, network hub, repeater hub, multiport repeater, or simply hub [a] is a network hardware device for connecting multiple Ethernet devices together and making them act as a single network segment.
A router [a] is a computer and networking device that forwards data packets between computer networks, including internetworks such as the global Internet. [ 2 ] [ 3 ] [ 4 ] A router is connected to two or more data lines from different IP networks .
Using the switch to connect only the systems that are communicating provides much greater security than a network hub, which broadcasts all traffic over all ports, [3] allowing an eavesdropper to intercept and monitor all network traffic. A CAM Table Exhaustion Attack basically turns a switch into a hub. [4]
In data communication, a physical network node may either be data communication equipment (DCE) such as a modem, hub, bridge or switch; or data terminal equipment (DTE) such as a digital telephone handset, a printer or a host computer. If a network is a local area network (LAN) or wide area network (WAN), every LAN or WAN node that participates ...
The hub manages and controls all functions of the network. It also acts as a repeater for the data flow. In a typical network the hub can be a network switch, ethernet hub, wireless access point or a router. The star topology reduces the impact of a transmission line failure by independently connecting each host to the hub.
Router: a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. A data packet is typically forwarded from one router to another through the networks that constitute the internetwork until it reaches its destination node. [3] It works on OSI layer 3. [4]
A local area network (LAN) is a computer network that interconnects computers within a single physical location. It is the most common type of computer network, used in homes and buildings including offices or schools, [ 1 ] [ 2 ] [ 3 ] for sharing data and devices between each other, including Internet access .
