type networking

well that ques has a very big big answer basically in a cafe u would have a lan and for a lan u can use cat5 that is a stp cable it would give u goof speed of 100Mbps now for connectors if u have money and skillful people for configuration u can go for a switch or even a router but if u dont have then use hub and too active hubs ok it would help more as they r bit intelligent and less in cost i think u would go for a star topology only using a hub thats all but u can seperate the 25 in two groups take two hubs atleast and configure two separate lans it would be more faster and there would be less congestion ok due to less systems in a single lan

hi friends In networking mainly 3 types of networking 1). LAN(local Area Network) 2). MAN(Metro politan Area Network) 3). WAN(Wide Area Network) In a small networking we'll used LAN only

if u have 25 computers its better u to choose LAN{local area network).thera are other types of networks such as MAN(metro politan area network),WAN(wide area network) these netwoking types will used when more number of computers are employed for work.

depends on what you mean by types? there are wireless, satelite, utp cable, bus topology, star topology.. hhehehe, anyhow, for 25 pc, in human language, i guess, err. let's see, are all the PCs in a room. if so, you need only network cards (NIC), most new PC comes with it. UTP cable or also called network cable or CAT5 cables, 2 x 16 ports or 24 porst switchs to connect the cable from each of your PC to the switchs, so that all PC can be connected to play network games, online games, sharte internet, etc... up to you.. cheers, hope this helps
