A "PGA tournament" is any tournament on the PGA Tour while the Masters is a specific single tournament.
That said, the PGA Championship is a single event which is often referred to as "The PGA Tournament". The PGA Championship is played at a different site in the US from year to year - although several courses have hosted the Championship more than once. Some of the courses have been private clubs while others have been public clubs. The Masters is ALWAYS played at Augusta National Golf Club, a private club. Membership at Augusta National Golf Club is strictly by invitation; there is no application process.
Both tournaments are by invitation only, but the PGA does not explicitly invite any amateurs while the Masters invites both professionals and winners of amateur tornaments. The only way for an amateur to guarantee an invitation to the PGA Championship would be to win one of the other PGA majors - i.e. the Masters, the US Open, or the Open Championship. Realistically, if an amateur were to win the British Open they would probably also garner an invitation to the PGA Championship.
2010 is the 74th Masters.
Many golf tournaments are held in April, but the most famous tournament is the Masters, held in Augusta, Georgia. The four "major" golf tournaments are the Open, the US Open, the Masters, and the PGA Championship.

Participation in the Masters golf tournament is at invitation only and the field of players numbers about 90. This makes it smaller than most professional golf tournaments.
