A machine is something which makes our task easy or simple.

• It saves our time.
• It saves our energy and
• It helps us in performing our tasks with perfection.

There was a time when we used to do our work manually. We used cover long distances on foot, we used to calculate big calculations manually, we used write letters instead of using a phone and we used to beat the heat of summers by living in the woods and in the mountains. But with the invention of machines our life has got changed completely. Our life has not only got comfortable but has become more speedy.

Common machines of 2012 are ACs, Cars, Computers, Airplanes, Hydrolic cranes, Load lifters, Cell phones etc

With the invention of computers we are:

• Doing tedious calculations which we used to do manually.
• Communicating with our frinds, relatives, employers etc through emails, voice calls, video conferencing, instant messaging etc
• Saving our precious time and
• Saving paper.

With the invention of fans, water coolers, air conditioners etc we are cooling our offices, cars, buses, hospitals etc. With the help of these cooling machines we are no more uncomfortable staying in a desert. With the invention of wheels, petrol engines, GPS navigation system, automobile engineering etc we are traveling at high speeds. We are completing big construction projects too and on time. Those animals which we used to use for big construction projects have got replaced by the Hydrolic Cranes and Load Lifters. Machines are helping us in our kitchens as well. With the help of an oven we are baking our pizza pretty quick. With the help of a water purifier we are purifying the contaminated tap water in no time and with the help of a cell phone we are talking to our dear ones without cables and at no cost.
