Fourth‚ protocols promote compatibility among network devices. To transmit and receive data successfully‚ the various devices involved in a particular session must conform to a mutually acceptable mode of operation‚ such as synchronous and duplex‚ or half duplex. Without protocols to provide such conformity‚ messages sent between devices would be distorted and garbled. Finally‚ protocols promote network designs that are flexible‚ expandable‚ and cost-effective. Users

The object of ball bearings (and roller bearings) is the substitution of pure rolling motion for plain sliding friction. <br> <br>Ball Bearings rely on the rolling motion of hardened steel balls to absorb loads. This rolling motion produces far less friction than the sliding motion. These steel balls are held in circular rows between an outer and inner ring‚ which have raceways‚ or slots‚ grooved into them to guide the balls. Ball bearings are available in both filling-slot and no filling-slot types

Potholes are caused due to poor quality and badly maintained roads. The constant movement of the overweight vehicles like trucks is also responsible for these ill roads. This ill quality roads will cause severe damage to the vehicles in terms of tyres and the shock absorbers and most important thing is the accidents which is caused due to this. A system called Pothole Detection System which detects holes on roads or uneven roads. So that it helps in maintain the roads in a good condition. Here two
