Which stackable switch feature allows for interconnection of multiple switches and will provide a cost effective solution for networks that require high bandwidth and high availability?
special backplane port
What are VLANs used for?
VLANs provide the capability so virtually segregate traffic on a network. VLANs work by tagging traffic packets and ensuring that packets with separate VLAN IDs are only available at ports which have been configured for that VLAN ID.
How do off switches work?
Off and on switches connect to a current. An on switch allows the current to run through an object, essentially "turning it on". Off switches cut of this current.
Does the contrast utility accessibility feature allow you to select a color scheme setting in which you control the contrast between text and background?
Yes, the High Contrast accessiblity feature allows you to do so.
What feature connects island to mainland?
An isthmus is a narrow strip of land that connects an island to the mainland. It is a natural feature that allows for land access between the two land masses.
Which type of firewall serves as a relay between users and servers on the Internet and inspects all traffic and allows or denies traffic based on a set of rules?
packet filtering firewallproxy firewall
What do switches do?
A switch is a device that segments networks into different subnets. Segmenting the network into different subnets keeps one network from overloading with traffic. Therefore, a switch forwards all data in the data layer and sometimes the network layer as it filters the data. A switch allows a connection to be established and it terminates a connection when there is no longer a session to support. Prior to switches there were hubs. Hubs also connected multiple independent (connected) modules in a network, but they were not as efficient as switches. Since most switches work in Layer 2, and not in Layer 1 like a hub, they are better at filtering data. A switch looks for Ethernet MAC addresses, keeps a table (the bridge forwarding table) of these addresses, and navigates the switch between ports. The switch prevents collisions and gives full bandwidth to each connection at the switch port. Switches save bandwidth by only sending traffic to destinations that have traffic. When a switch switches Ethernet frames, they monitor the traffic for the response from that frame and see what device, on what port, responds to that flooded frame. There are different types of switches that range from "dumb" switches that lack manageability and can monitor only 4-8 ports to "managed" switches that can get statistics on switch traffic, monitor connections, and hard-code up to 96 port speeds and duplex. Then again, there are "chassis-based" switches with blades or cards that perform not just switching, but routing and intrusion detection too! If you are interested in this, look into Cisco's Catalyst 6500 Series. Another type of switch preferred by large enterprises is the "Layer 3 Switch," because it has the functionality of a router .
What does a solenoid do on a riding lawnmower?
It works as the connector between the battery and the starter. When the key is turned the solenoid makes the connection between those two cables and allows the engine to crank over. If the mower is equiped with safety switches they override the connection and keep the solenoid from working until all the switches have been closed.
What feature that enables Excel to create a series automatically?
The Fill Series feature allows you to do this.
What is a VLAN trunk?
A VLAN trunk allows for data to travel across a single link between two devices even if the data is from multiple VLANs. This allows for reduced cabling needed as for you won't have to run multiple cables between switches in order to have up-links for every VLAN.
What are the key features of garmin mapsource?
There is one big key feature of Garmin mapsource. The great thing about Garmin mapsource is that people can report a crash while they are sitting in their car which allows other to avoid the traffic.
