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.

When every part of a device is connected externally using basic wiring it is called electrical. The wiring is used for supplying power in form of electricity which can be either AC or DC current. That why most of the electrical devices are huge in size and not easy to transport.

Motherboard is the backbone and integral part. It is also known as circuit board. This contains all the parts in the form of chips. There are many thin silver lines running across each chip.The chip holds the memory of the device.

We can listen to our favorite music on a radio. This machine is designed to catch frequencies of different countries so that we can listen to songs in various languages. Mobile phone is an amazing piece of equipment that we can carry in our pocket and talk to anybody in the world.

Hard drive is designed to store the information or data permanently. The power supply unit ensures the electricity is supplied to all the parts of the computer. Apart from computer the chips are present in our mobile phones, tablets and other day to day gadgets. There are micro and macro chips according to the size.

The architecture involved in designing circuits is called CAD also termed as Computer Aided Design. This is where the blueprint of a part is drawn determining specific functionality. Earlier the skeleton of a machine is drafted manually. Sometimes we see the product does not function as expected. There is a breakthrough in medical science due to this technology. We have found a remedy for early detection of deadly disease like cancer.

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.

After the industrial revolution the technology has been the major life changer for mankind. The drastic change was a necessity for humans. It was a step towards seeing the world in a new way. Initially it started with the industry trying to produce commodities in a faster pace.

So more people to produce high numbers cost more money which is not a intelligent business strategy. This is the reason why humans invented machines for mass production. This considerably reduced resource, time and cost for manufacturing. The profit margin considerably increased across industries.
