Throughput

Written in bytes per second (or other magnitudes), which is the amount of data passing through the medium per second. Typically on networks we use bits rather than bytes, just because they started like that.

K means a 1000 or 1024? In networks we only care about base 10, but in computers themselves (ie: OS's) they use powers of 2.

K: ${10}^3$
M: ${10}^6$
G: ${10}^9$
