Administration of SharePoint products and technologies can be complex, but fortunately Microsoft has centralized the vast number of administrative functions into a small number of highly powerful tools. Familiarity with these tools, and in particular with the SharePoint Central Administration tool, is subsequently a must for a SharePoint administrator.
In addition to the SharePoint Central Administration tool, powerful command-line administration using PowerShell and the legacy STSADM tool is available, and database and IIS-specific administration tools provide for additional administrative functionality. Through the use of these tools, administration of a SharePoint environment becomes more streamlined and capable.
