Key Features
Hubs: There are a large number of devices that can be called hubs, some of which are not usable on Ethernet networks, and others that are Ethernet hubs. For a small network, selecting a hub is generally a matter of getting a good price and anticipating your network's expansion. Switches: Devices that filter and forward packets between LAN segments. KVM (Keyboard,Video,Mouse) switches allows control over more than one computer and are popular among users who have upgraded their home PC systems and want to still use their old computers but do not want to invest in a second keyboard, monitor and mouse.
Layer 2 Switches (The Data-Link Layer) \r\nLayer 2 switches operate using physical network addresses. Physical addresses, also known as link-layer, hardware, or MAC-layer addresses, identify individual devices. Most hardware devices are permanently assigned this number during the manufacturing process. \r\nSwitches operating at Layer 2 are very fast because they only sort physical addresses, and don¿t look at the data packet very closely to learn anything more about where they are sent.\r\n \r\n Layer 3 Switches (The Network Layer) \r\nLayer 3 switches use network or IP addresses that identify locations on the network. They read network addresses more closely than Layer 2 switches, identifying network locations as well as the physical device. A location can be a LAN workstation, a location in a computer's memory, or even a different packet of data traveling through a network. \r\n \r\nSwitches operating at Layer 3 are smarter than Layer 2 devices and incorporate routing functions to actively calculate the best way to send a packet to its destination. Although they are considered "smarter", they may not be as fast if their algorithms, fabric, and processor do not support high speeds.
