Watch Zaheer Khan in this video, he take 4 out of his 5 wickets around the wicket !!

A right arm bowler, bowling round the wicket has the umpire to his left just before delivery of the ball. And bowling over the wicket has the umpire on his right side.

Like wise a left arm bowler bowling round the wicket has the umpire on his right and bowling over the wicket has him on his leftside.

the bowler who is bowling when his another arm is close to the wickets other than the bowling arm which rotates in circular manner to the wickets is AROUND THE WICKETS.

.1 Right arm bowler bowls from the left side of the wickets where his left arm is close to wickets (Right Arm Round the wickets)

.2 If the same bowler bowls it from the left side of the wickets where his left arm is not towards the wickets ( Right Arm Over the wicket?

If a right-arm bowler bowls around the wicket he is on the right-hand side of the umpire with his bowling arm facing the leg side to a right-handed batsman. A left-arm bowler operating around the wicket would have his bowling arm on the offside to a right-handed batsman.

The method of bowling in which a bowler delivers the ball from the side of the wicket that puts his dominant hand farther from the wicket.

And opposite of it is 'Over the wicket' in which your dominant hand is nearer to the stumps(wickets)

If the bowler is right handed, bowling to the right hand side of the stumps is round of the wicket and for a left handed bowler to the left hand side of the stumps.

A bowler bowling round the wicket means his non- bowling arm is nearer to the stump while bowling.

Edit:

Who is the fool here who thumbs downs the right answers?

to confuse the opposition for taking the wickets.

Non-Bowling arm is nearer to stumps.

Right end of the umpire.
