1 DNA and RNA base pairing is slightly different, since DNA uses the bases adenine, thymine, cytosine, and guanine; RNA uses adenine, uracil, cytosine, and guanine. 2  Uracil differs from thymine in that it lacks a methyl group on its ring.

Linux has a notion of Load Average which is defined as: System load averages is the average number of processes that are either in a runnable or uninterruptable state. A process in a runnable st...
For example, one can interpret a load average of 1.73 0.60 7.98 on a single-CPU system as: during the last minute, the system was overloaded by 73% on average (1.73 runnable processes, so that 0.73 processes had to wait for a turn for a single CPU system on average). during the last 5 minutes, the CPU was idling 40% of the time on average.
