Earlier every electronic devices were large in size and bulky. It was a challenge in transporting and carrying these machines from one place to another. It is amazing to see the size of these devices started shrinking over the period. Today we almost carry most of these gadgets in our palm or pocket. This is entirely a new era of macro managing which are wave soldering and PCB assembly board.

The technological advancement in electrical engineering in making the devices smaller is called electronics. In order to shrink the mass we have to connect the parts internally. This is achieved by connecting using liquid metal like mercury or copper on a circuit board. Devices are not only smaller in size but they consume less power. Mostly the type of power used is DC current. This has created a revolution in the field of engineering.

The device does not work if motherboard is broken. There is no way that we can attach. The only option is to replace the circuit. The blueprint or the design can be obtained on a transparent paper which helps us to reconstruct the appliance as many times as we want. There are printed motherboards available in the market which makes lot easier in constructing a circuit.

This appliance created for producing visual effects with varied colors which are generally coded in RGB. The combination of red, green and blue color forms a picture. A printer is a piece of equipment that prints beautiful color picture on a paper. It uses various colored ink to produce text or picture.

Chips are different parts in a circuit board that performs specific function. CPU, RAM, SMPS and Hard Drive are some of the examples of chips in computer that does specific activities. This is quite similar to the human body like we have heart, brain, arteries and stomach. CPU is the central processing unit which contains the processor which keeps ticking like a clock every millisecond. The random access memory stores the information temporarily whenever required.

It is an amazing experience of human interaction with computer. The art of making a machine intelligent enough to design a product on its own without human intervention is known as artificial intelligence. We can also make computer to design large machines which is known as computer aided manufacturing or CAM.

The advancement in technical side has simplified our living to a great extent. Technology is there in every sector construction, entertainment, Artwork, Sports and each and every aspect of our life. It used to take a year to construct a building now it takes just a month.Technology has an impact on cultural change. People prefer to share their emotions through social media rather than physical interaction.

What we think was impossible is possible now. The technological revolution has completely taken humans into a new dimension altogether. This change has increased the morale and confidence of a man to the skies. There is a vast difference in the social and economic status now compared to the earlier days.

Producing at large quantities is a crucial aspect in any business. With the increase in population the demand is increasing hence we have to look at ways to increase the supply maintaining the same cost. Today every commodity in the market is produced in mass within no time. This is achieved from automation. This process has increased the production ten folds.
