yes each and every device in a network will have unique mac address.
What is the difference between green networking and green computing?
Green networking is ambiguous. It could be a group of environmentalists meeting together. Or it could mean energy efficient ways of running a network as is the context here. Green computing is more general since not all computing is network related. Green networking would use green computers.
Green networking includes:
- Consolidating servers when practical. Server consolidation is the digital equivalent of carpooling. Just like carpooling means less vehicles on the road and less fuel used, less servers means less computers and less electricity used.
- Using server virtualization to make consolidated servers seem less complex. That way, it seems like you are running different servers on the same computer, and you can run multiple servers on one computer as you would on multiple machines.
- Using systems management to increase efficiency. That way, you can balance productivity and usage with costs. You might decide that it would be more efficient to outsource your server requirements. A dedicated server company might do the job more efficiently and cost effectively.
- Upgrading older equipment to more energy-efficient products. This one is obvious. Newer mainstream computer systems tend to use less power these days than previously. But even if they require more power, it may be possible to use less of the newer computers to get same or more productivity than with the older one.
- Substituting remote administration videoconferencing, and telecommuting for travel. While this can result in more electricity being used, it is still in the spirit of green networking and computing practices since you would use less fossil fuels and hopefully create less environmental impact.

How do you repair the accidentally cut fiber optic cables?
If you accidentally cut a fiber optic cable, you will need to contact your phone company immediately. This is who owns the cable and they will have to repair it. They will charge a large amount of money because you did not locate the lines before you started digging.
Why is MPLS pricing for private WANs so much more expensive than a regular ethernet connection?
MPLS pricing for private WANs is much more expensive because it is private and is said to have a faster internet connection because not as many users are linking up to it as opposed to a busier public high-traffic WAN.
The seeds INSIDE the packet should be. The packet itself is paper or foil and is of course, not alive.
Who do I call when I cut buried fiber optic cables?
You can call the company that installed the cables or any company that installs fiber optic cables. It's always a safe bet to call a professional before digging in a area where you think there may be cables buried.
Is your wep key your product key?
No. Your WEP key is the password placed on the router you are trying to access.
Is there any way to combine two Broadband connection?
No, there is no any device yet build to do that, but yes you can use the load balancing between two different internet connection, if your both connection speed is 1 mbps and you using load balancing feature then your 1st download speed is 1mbps but at the same time if you downloading another file then 2nd file also downloaded with 1mbps speed. if you are downloading 4 files at the same time the download speed for each file is 512 kbps.
What is the web server response to the web client GET request?
The response from the server is:
HTTP/1.1 200 OK
This means that the request from the client succeeded.
If the page you requested is already stored in the cache of your browser you will get:
HTTP/1.1 304 Not Modified
This means that the page has not been modified since it was stored in your cache.
jump around and it will work out
Your computer cannot see others on the lan why?
Are you sure your on the LAN and the same subnet. Could be a number of things. Though you'll probably find its a security precaution. I use a program on all my LAN's which make each computer invisible to the other.
Im assuming your just not getting a ping reply. If this is the case, it could be firewall settings. Ping the ip and ping the name (only if you have reverse dns set-up).
Name a difference between a mainframe with terminals and a network of computers?
For a mainframe with terminals, data processing takes place on the mainframe computer only as the terminals are 'dumb'. Conversely, in a network of computers, each computer has its own processor.
What kind of wing chun was used in Ip Man?
the wing chun kind. although wing chun is taught with slight variations it doesn't have "kinds" although if you are asking because you want to learn the method closest to grandmaster yip mans teachings it is possible to find teachers who teach (or at least claim to teach) methods that were passed down from yip man himself but the closest thing would be to learn from yip mans son yip chun who is in his mid 80 and still one of the top practitioners.

Why is a proper server shutdown important?
Because the server operating system finishes writing data from clients and data that is in memory. If you shut the server down abruptly that data is lost. Also data can become corrupted. Either way, you end up with lost data. Usually servers are run in business environments and the lost of any data is considered unacceptable to them.
In computer terms what does TOPOLOGY stand for?
Topology refers to the way equipments are connected one to another. For example, in a star topology all machines are connected through a central connector (a hub or switch), in a full mesh every equipment is connected to every other equipment, etc.
