Many different modes of operations (10BASE-T half-duplex, 10BASE-T full-duplex, 100BASE-TX half-duplex, etc.) exist for Ethernet over twisted pair, and most network adapters are capable of different modes of operation. Autonegotiation is required in order to make a working 1000BASE-T connection.
The 10BASE-T standard was devised to be used with existing twisted pair cable installations with straight-through connections. When a terminal device (with an MDI port) is connected to a switch or hub, this crossover is done internally in the switch or hub ( MDI-X port).
To connect two ports of the same configuration (MDI to MDI, or MDI-X to MDI-X) with a 10 or 100 Mbit/s connection (10BASE-T or 100BASE-TX), an Ethernet crossover cable is needed to connect the pair that each interface transmits on to the receive conductors of the other interface.
A cable terminated according to T568A on one end and T568B on the other is a crossover cable when used with the earlier twisted-pair Ethernet standards that use only two of the pairs because the pairs used happen to be pairs 2 and 3, the same pairs on which T568A and T568B differ. Crossover cables are occasionally needed for 10BASE-T and ...
The configuration of 100BASE-TX networks is very similar to 10BASE-T. When used to build a local area network, the devices on the network (computers, printers etc.) are typically connected to a hub or switch, creating a star network. Alternatively, it is possible to connect two devices directly using a crossover cable.

Autonegotiation can be used by devices that are capable of more than one transmission rate, different duplex modes (half duplex and full duplex), and different transmission standards at the same speed (though in practice only one standard at each speed is widely supported).
