Computer network

A computer network is a system for communication among two or more computers.

Computer networks may be categorized with respect to range:

• personal area network (PAN)
  • wireless PAN
• local area network (LAN)
  • wireless LAN
• metropolitan area network (MAN)
• wide area network (WAN)

Computer network applications may be categorized with respect to the functional relationships between components:

• client-server
• multitier architecture
• peer-to-peer

Computer networks may be categorized with respect to network topologies:

• star network
• grid network
• toroidal networks and hypercubes
• tree and hypertree networks

Computer networks may be implemented using a variety of protocol stack architectures, computer buses or combinations of media and protocol layers, incorporating one or more of:

• ARCNET
• DECNET
• Ethernet
• IP
• TCP
• Appletalk
• Token Ring
• IPX
• FDDI
• HIPPI
• Myrinet
• ATM
• RS-232
• IEEE-488
• USB
• IEEE 1394, aka Firewire, iLink
• X.25
• Frame relay
• Bluetooth
• IEEE 802.11
• System network architecture

And face the chances of them 'ungry guns. It's that wot makes me snarl and set me jor: If I gets knocked out in this blasted war? But . . . wot the 'ell, Bill? Wot the 'ell? Ay, wot the 'ell's the use of all this talk? And some of 'em they 'ad no legs to walk, And -- well, I couldn't look 'em in the face, I'm under forty-one and take me place A fool, you say! Maybe you're right. I've ceased to think; I only know The Convalescent . . . So I walked among the willows very quietly all night; There was no light at all, at all; I wint from tree to tree, And I listened and I listened, but I nivver heard a moan; I was lookin' for the livin', but I only found the dead. Sure I know that it was Shamus by the silver cross he wore; Oh I had no time to tarry, so I said a little prayer, And it's Springtime, and I'm thinkin' that I only dreamed it all; Where I knelt beside me brother when the battle-dawn was red. Where I prayed beside me brother ere I wint to fight anew: Where all is love and laughter, sure it's hard to think of loss . . . The Man from Athabaska Oh the wife she tried to tell me that 'twas nothing but the thrumming And she thought that I was fooling when I said it was the drumming .
