What do you understand by the term 'Fundamental Rights'?

Modern age is the era of democracy. Every democratic country grants its citizens some special facilities for their progress and development. We can call these facilities as the right. The conditions which are considered more essential are called the Fundamental Rights. These are called Fundamental Rights as:
(i) These rights are essential for the all round personality development of an individual.
(ii) These rights are included in the constitution of a country as such.
(iii)  Every activity by the government and the law erected by the parliament should be conditioned by the rights.
