A Brief History of Computer Development

Computers have developed since its first use in the late 19th century. The first generation which was a room-large sized has shrunk into a much slimmer and smaller design. Even with the small size, the current computer has hundreds, even thousand times speed in processing data.

Nonetheless, whiners are everywhere. You can find a lot of people complaining about how slowly their computers work even though many major updates and upgrades have been taken. We have good news for those people, or you: a new generation of computer is right in front, and it definitely will outrun the speed your current computer is having now, and no, it’s more beyond upgrading the RAM.

What is it?

PCBOptical computer, as its name suggests, uses light to process data. As you all know, light travels faster than anything else in the universe. In other words, optical computers will be the fastest working computer ever.

The use of light in transferring data itself has been used in fiber optic wiring. Those who witness the shifting between the old copper wire to fiber optic would know what difference this will make.

How does it work?

Computer ChipThe optical computer uses photons to transfer data. The photons travel literally in a speed of light. Current computer, on the other hand, uses electrons to do all the works and that is why it is called an electronic computer.

The computer will use infrared as the medium to process the data. There is a reason as for why infrared was chosen. It is because light could carry a huge amount of data and infrared has the smallest capacity which your current computer could handle.

Nonetheless, some challenges cannot be ignored

Personal ComputerThe data that photons could carry is much larger than that the current computer could handle. It needs a special microchip to read the data. Electronic computers do not have sufficient retrieving instrument that could manage the enormous size of data that flood in at the same time. Thus, until the particular component is created, which scientists believe will be very soon, you can be happy with your computer for now.


Not only that, an optical computer can work so fast that the data that has been stored from all over the world so far can be accessed in a blink of an eye. Many believe that this will bring out unwanted privacy exposure. Who would want their bank, health, or marriage record available to be accessed by literally anyone in a short time? Not to mention national security issues too.
