The system of 'checks and balances' refers to a principle of government under which separate branches are empowered to prevent actions by other branches and are induced to share power. Here's what each point means:

i) Horizontal distribution of powers: This refers to the division of powers among different branches of government - typically the legislative, executive, and judicial branches. Each branch operates independently of the others, but all are equal in status and have powers that the others cannot infringe upon.

ii) Separation of powers: This is a model for the governance of a state where the state is divided into branches, each with separate and independent powers and areas of responsibility so that the powers of one branch are not in conflict with the powers associated with the other branches.

iii) Put a check on the exercise of unlimited powers of government by maintaining a balance of power among various institutions: This means that each branch of government can limit, or check, the power of the other branches to prevent any one branch from becoming too powerful. For example, the executive branch can veto laws passed by the legislative branch, but the legislative branch can override that veto.

iv) Federal division of powers: This refers to the division of powers between the central government and individual states. Both levels of government are sovereign in their respective spheres of authority. This system is designed to ensure that no single entity has complete control over the country's governance.
