@Processing is done at client side.
I feel processing is done both on client and server side depending on requirement. BL are usually on server side (sitting beside data tier). Usually presentation and few client centric processing are done at client side. Conceptually, client machine is considered to be dumb or minimal machine. Thats why processing are delineated to central server etc. May be you could elaborate your article.
i did not get the information about 2-tier and 3-tier archietecture
