All actions which have the objective of retaining or restoring an item in or to a state in which it can perform its required function.The actions include the combination of all Technical and corresponding Administrative, Managerial and Supervision action. Ref….Wikipedia.org
A machine consists of a power source and a power transmission system, which provides controlled application of power. It uses gears and gear trains to provide speed and torque conversions from a rotating power source to another device.
It allows the outer drive wheel to rotate faster than the inner drive wheel during a turn.This is necessary when the vehicle turns, making the wheel that is travelling around outside of the turning curve roll farther and faster than the other.
It is a base of two process. Digitized information is recorded in binary code of combinations of digits 0 and 1, also called bits, which refers word and images.It enables immense amount of information to be compressed on a storage device that can be easily preserved and transported. It transformed how people communicate,learn and work.
There are 3 types such as Portable, Semi-Portable and Volatile methods. Portable method consists of Memory Card, Disk Drive, ROM catridge, Flash memory etc.,. Semi-Portable method consists of Hard Disk, non-volatile ROM, and Volatile methods include Volatile RAM, Neurons.
In simple terms,a software programme consists of two main codes “Source Code” and “Object Code”. Source code is written in computer programming language which can be understood only by a computer professional. To use the software code the source code is converted to object code by a programme known as “Compiler”. Any upgradation can be done only at Source code. In the Open source it is available at Free where it is vice versa in a licensed programme.
It is an automobile transmission that does not change gears automatically, but rather facilitates manual gear changes by dispensing with the need to press a clutch pedal at the same time a changing gears.
The basic circuit is Tank – Pump – DCV – Motor – Tank. When the DCV is at neutral position the hydraulic oil flows back to the tank. This type of circuit is inexpensive and is used for constant displacement pumps.
The basic circuit is Tank – Pump – Motor – Pump. Here the DCV is avoided. The oil from the motor is send back to pump inlet. These are used for hydrostatic transmissions. The response is better and works with higher pressure. Comparatively this is expensive and is used with variable displacement pump.
