The Terms About Memory

When I use top, it displays the following about the memory information. What are the meanings of actv, in_d, in_c and and cached?

Mem: 2581428k av, 2522240k used, 59188k free, 0k shrd, 329648k buff
1743216k actv, 0k in_d, 54704k in_c
Swap: 1052216k av, 214328k used, 837888k free 1666468k cached

also, I use free,

total used free shared buffers cached
Mem: 2581428 2527264 54164 0 329676 1666676
-/+ buffers/cache: 530912 2050516
Swap: 1052216 214328 837888

What's the "-/+ buffers/cache" supposed to mean? What's the difference between cached and buffers?
