Everything we see around us when we look around us is made by technology. At present, new scientific discoveries are being made on a daily basis. New models of TVs, fridges, ACs, mobile phones, computers, motorcycles, cars, etc. are being dumped in the market every day. Just as the market is full of all these things, our home is also full of many of these things. That is why the modern age is called the age of science and technology.Today everyone wants a home with all the material things of the present time. Materials of material comforts like TV, fridge, AC, mobile phone, computer, washing-machine etc.
