What does standard error, and Pr(>|Z|) mean in GLM?

I received these output from R:Estimate, Std. Error, z value, and Pr(>|Z|). I know z value = Estimate / Std E, but what exactly is "std. error" and Pr(>|z|) mean?

The "Pr(>|z|)" is the so called "p-value" of the test for whether the coefficient point estimate is significantly different from 0. Intuitively, it tells us if our point estimate has been calculated precisely enough to distinguish it from zero. We typically define "precisely enough" using the $p < .05$ maxim.
