Blocking 101

Pretty new to SQL Server and support multiple applications on SQL Server.
Just encountered a situation where "blocking" was occurring.
Can someone provide me more information or a link explaining Blocking and
how I can use SQL Server Enterprise Manager to determine who and what is
causing the blocking.
Any help is appreciated and I Thank You in advance for your help.
