Parliamentary Model
Theoretically, the legislative branch of government has more power in a Parliamentary system than in a Presidential system of government.
In a congressional system the President holds a lot of power, hence the name executive branch. In a parliamentary system the power is spread wider out and one person does not have absolute power. In a parliamentary system there is a wider representation of people, more representatives, and many different positions.
Parliamentary democracy
It can be, but not necessarily. A unitary state is simply one where the power is centralized in one place and contrasts with a federation in which power is divided among states/regions and a central government. For example, the UK is a unitary state (for the most part) whereas the US is a federation. A parliamentary form of government simply means that the executive branch/ministers/cabinet are part of the legislative body. Both unitary and federal states can have parliaments. For example, India is a federation with a parliamentary system where as the UK is a unitary state with a parliamentary system.
The statement, "The parliamentary form of government gives most of the power of government to the executive" (that is, to the executive branch of the government), is in fact generally false. While an executive branch of a parliamentary system may in fact have tremendous freedom to act politically as its particular genius dictates, it nevertheless receives legitimacy from the legislative branch of the government, which retains the power to revoke the power of the executive branch by formal schedule, in identifiable emergency-situations, or otherwise.

Multiple political parties are most common in a parliamentary system. In this system, parties often form coalitions to achieve a majority, reflecting a wider range of political views and interests. This contrasts with a two-party system, where two dominant parties typically compete for power. Countries like Germany and India exemplify parliamentary systems with multiple active political parties.
Most countries in Europe are parliamentary democracies, including the UK, Netherlands, Ireland, Germany and Austria. France and Russia have a semi-presidential system of government. Europe's only dictatorship is Belorus.
Parliamentary is the British political system. Presidential is the American political system.
No
Generally, a Parliamentary system will get work done quicker, but a Presidential system is sometimes desirable because it partly limits the government.
