To those who have spent a dozen years wrestling with balky PCs and their inexplicable crashes, disruptive and costly hardware and software upgrades, and insatiable demands for service and support, the network computer offers simplicity. Stripped of the hardware and software that complicate PC life and only capable of network access and display, the network computer relies on the network for virtually all software, services, processing, data, and resources.

We first state general linear model, ridge-type estimator and general ridge-type estimator, and the constraint biased estimator. And then, we introduce some basic theory about matrix and some conclusion about the admissibility of estimator in Gauss-Markov model. In the third chapter, we discussion several equivalent characterization of the best linear unbiased estimation, we proved that admissible characterization of admissible of linear estimation is as conditional general ridge-type estimation in general linear model. A necessary and sufficient condition that homogeneous linear estimator is admissible estimator is obtained.
