Basic notions of networking
Network (computing)#
Set of computers linked together (cable or wireless). These computers can remotely:
- Share resources (modem, hard drive, CD-Rom drive, applications, etc.)
- Exchange data: documents, chats etc.
Network cables or ethernet cable#
- UTP-CAT5 (Unshielded Twist Pair Category 5): 100 megabit/second
- UTP-CAT6 (Unshielded Twist Pair Category 6): 1gigabit/second
- straight ethernet cables: connects a computer to a switch
- crossed ethernet cables: connects 2 computers together
Network card#
Hardware that provides access to the network. This is where the data passes. The network card provides a MAC address to the computer in question in order to identify it on the network (physical address). A network card attaches to the computer’s PCI port.
