Hydraulic turbines 1.Converts hydraulic energy into mechanical energy. 2.Produces electrical energy. 3.Very costly and have cumber some design. 4.Maintenance cost is high as it has many confidants. 5.Examples- pelton turbine,francis turbine, Kaplan turbine, etc. Hydraulic pumps 1.Converts mechanical energy into hydraulic energy. 2.May utilize electrical energy to produce pressure energy. 3.Less costly and easy design consideration. 4.Less maintenance cost as it has very less components. 5.Examples - centrifugal pumps, reciprocating pumps.
( RAM) Randam access memory is a volatile memory. This means that is lose all its data when the power is switched off. It is also known as the main memory of computer system that store the data temporarily and allows the data to be accessed in any order. The data can be accessed at a faster speed in RAM as compared to the secondary storage because it is the internal memory of the computer . RAM consists of different ICS, which are mounted on the printed circuit board. RAM stores the application programs and the data on which the user is currently working so that the processer can easily access the required application program and data in a less amount of time. RAM is also known as read, write memory because I can perform both read as well as write operation. The storage capacity of RAM is uselly less than secondary storege devices. RAM can be of two types _ static RAM and dynamic RAM.
