High level view: Teaming is having two network cards operate as a single card in the OS. This is good if one fails, as the other continues to work.

From intel white paper:
Features available by using Intel's Advanced Networking Software (ANS) include:
Fault Tolerance
Uses one or more secondary adapters to take over for the primary adapter should the first adapter, its cabling or the link partner fail. Designed to ensure server availability to the network.
Link Aggregation
The combining of multiple adapters into a single channel to provide greater bandwidth. This only works widens bandwidth to multiple destination addresses. ALB mode provides aggregation for transmission only while RLB and LA/FEC/GEC/3ad modes provide aggregation in both directions. FEC/GEC/LA/3ad modes require a matching aggregation capable switch, while ALB and RLB modes can be used with any switch.
Load Balancing
The distribution of the transmission and reception load the among aggregated network adapters. An intelligent adaptive agent in the ANS driver repeatedly analyzes the traffic flow from the server and distributes the packets based on destination addresses. (In LA/FEC/GEC/3ad modes, the switch similarly provides load balancing on incoming packets.)
Note: Load Balancing in ALB mode can only occur on Layer 3 routed protocols (IP and NCP IPX). Load Balancing in RLB mode can only occur for TCP/IP. Multicast/Broadcast and non routed protocols (NetBeui, Microsoft* IPX, etc.) are transmitted only over the primary adapter.

Not wishing to be pedantic, but I'd say that it 'is having two or more network cards'

Pfft, that waspedantic.Burbleflop said:
I'm sure that in this case, we are talking about 2.

Pedantic, but factually correct. How can you be sure the OP was talking about 2? It is a reasonable assumption given that a lot of servers come with dual network cards but it wasn't actually stated.
