Are there any switches which are powered by poe?
No, there are no switches that are powerd by POE.
The POE uses one of the 4 pair in CAT cabeling so reasonably priced POE switches are slow 100Mb ps. POE switches use a LOT of power 8watts per port.
Costs are coming down now. £400 for a 24 port GB switch like Netgear GS724P. But does no-one at all do a small say 4-port switch powered by PoE, of which I could use many, to extend the number of points in our school network without rewiring.
Have just found that there are switches that are powered by PoE. Linksys SLM2005 and SLM2008 which are 5 and 8 port managed 10/100/1000 switches.
Your computer is refusing to update network drivers?
If you've been having computer problems and someone suggests that you "update your drivers" but you haven't a clue what that means, you're not alone. A lot of new computer users have trouble with the concept, but take heart, it's not hard to learn.
Here's a step-by-step on how to manually update your drivers below. However, if you are looking for a quick solution, here is a program that will seek out and manage drivers for you:
Try Driver Detective. Or download a Driver Detective Trial Version (note: a download will begin).
What is used to express gain of loss in a fiber optic system or component?
The decibel is used to express gain or loss relative to a known value. In fiber optics, the decibel is most commonly used to describe signal loss through the link after the light has left the transmitter.
microcomputers assign one device at a time. The channel/control units decide where the next byte can be found or stored from an external device. They are similar to how they store their data. They are different on how they operate.
An average quality network hub can cost around one hundred American dollars, a lower quality one may cost slightly less than that and extremely high quality one would probably cost significantly higher than most other alternatives.

How data can be transferred using wired and wireless methods?
This is assuming that there is no outside access to the Ethernet network such as a Internet connection. If there were then firewalls would be needed to prevent a outside intrusion of the network.
In addition to physical access security, a wireless network requires authentication and encryption to prevent unauthorized devices from connecting to the wireless network or capturing and decoding the data that is being transferred via a wireless network connection.
If the wireless network has outside WAN access then you would also need firewalls as with the Ethernet network.

Information or data is transmitted in digital computers by voltages that are switched on or off?
voltages must be on before data information can be transmitted in digital computers
and not so when using the internet, because the message is transmitted at the slightest glimpse of power source. does not need proper voltage to carry out transmission
Does SSL operate at the transport layer or application layer?
I've always considered it to operate at the transport layer as it;s simply an encrypted version of TCP. However, Wikipedia OSI-model lists it as operating at the presentation layer, as it's concerned with the transformation of data between the application and transport layers.
How can one address the security risks of network consolidation?
Several solutions exist depending on the type of consolidation and the needs of the company. Some include Virtual Private Networks(VPN), using gateway anti-spyware and anti-virus protection, URL filtering and anti-spam service.
What is the range of network id in class B ip address?
In a Class B range, the first network address would be 128.0.0.0 and the last network address would be 191.255.0.0
Class B addresses are assigned to medium-sized to large-sized networks with up to 65,534 hoasts per network.
How does lan architecture differ from a lan topology?
The LAN Topology is only one of the parts that make up a LAN Architecture. The Topology refers to the way the components in a network are physically connected and the most common Topologies in Ethernet are: Bus, Token Ring, and Star. Bus consists of a single cable segment with all the components connected to that single cable with T-connectors; Token Ring consists of, as the name implies, a cable ring to which all the components are connected and in which data flows in one direction except in the case of an interruption in the ring caused by a computer being down and a token is passed between the computers with whomever holds the token having transmit priority; the last and most currently used is the Star Topology in which all the components are connected to a switch that controls traffic between them. The Architecture encompasses more than just the Topology, defining the type of media (Twisted Pair/Fiber Optic) used to transmit the data, the speed of the transmission, the type of signal (base or broadband), and the maximum length of a segment of cable. Look up IEEE Ethernet Standards for Wired Networks for more information. Whoever answered this question before saying there's no difference has no idea what they're talking about, take it from someone who is studying Information Systems in business and is taking a test on precisely this subject in a LAN class the day after writing this. I hope I answered your question satisfactorily.
What is the difference between hard disks and floppy disks?
hard disks are generally contains within the computer and contain FAR more memory than a floppy disk does. floppy disks generally contain 1.44 mb where as hard drives are constantly developing and are currently about 1TB MAX. floppy disks are external in the same way as CD's
A modem is connected to a computer and a phone line. When the internet is required the modem dials up and ISP and connects to the ISP computers by a phone call. The phone call remains connected to the ISP computer until access to the internet is no longer required.
