a company has about 50 computers operating as stand alone machines in the 4 buildings on its 3 hectare sitethey wish to have the advantages of a central server for storage and linking to the outside Suggest a network structure which will allow the above to be met (Thanks)
You are right, they are reflectors! The best place to start, if you are interested in photography is a good 101 class in collegeIf you aren't in college yet, start with some classes in high schoolThat's when I caught the photo bug! I'm not a pro, but I love taking pics to this day! Good luck with your hobby! :)
They are reflectorsYou can use them too, to reflect light back into the shadow sideI would not suggest using aluminum foil, thoughThat might cause unwanted highlights and uneven lighting Just use a white piece of posterboard, or foam boardHave an assistant hold it and try different angles until you see the effect you wantIf you are taking just head shots, your subject might be able to hold a smaller piece just out of camera range themselves.
The simplest would be an extended LANAll the buildings would have a switch that connects the computersThe 4 switches connect to another switch You can also use four ethernet cards on the server to plug in the four incoming cables from the LANSThe LANs would be bridgedYou can install the server any where in the networkI would suggest DHCP over Windows Server 2003/Client configurationYou can share internet too using a proxy server (Winproxy, proxyi) or Internet connection seviceA switch is a box with 16/32/64 ports.
