For people who may not be strongly associated with the internal components and functioning of a computer, for them, the definition of computers may restrict only to the extent of an electronic device which performs the given instructions and delivers output. This definition sounds highly simple and to some extent is true. However, the functions of the collateral in-build devices such as the mother board, Registry, memory, hard drive etc have a great role to play in its smooth functioning.
Computer Registry, though may not boasts of its usage, however plays an integral role in the functioning of a computer. A computer registry is like a library catalog which stores all the information, settings, instructions, obsolete data etc and makes it available if asked to retrieve. An operating system cannot operate without the support of a good computer registry. It is the strong backbone of the system which facilitates its smooth functioning.
