the mauryan administration had four division …

Mauryan administration was centralised in nature with king as the sole authority of power .This is unlike modern day democratic system where administration is carried out through working of executive ,legislative and judiciary in close co-operation with each other.The administration today is highly decentralized with formation of panchayats ,gram sabhas etc
In judiciary the king was the supreme power he himself was the judge but in modern days judicial system is based on checks and balances where higher courts review function of lower courts and entire authority is not vested in one person.
Revenue system today is complex as earlier land was the major source of revenue during Mauryan times but today with coming up of industries ,advance trade there are many sources of revenue .
