Bandwidth - Whether it refers to FSB, memory or internet transmission, bandwidth is the rate at which data travels through a medium. MHz or Bps, more is better.
Latency (also called CAS Latency)
The amount of time in nanoseconds (often measured in clock cycles) between a request to read the memory, and when it is actually output. SDRAMs are typically referred to as CL2 or CL3, with CL2 parts being faster.
So less is better.
