From the size of your palm to gripping it with your two fingers. Something that enabled the computer to be what it is today in terms of electronics started off with vacuum tubes. These tubes enabled currents to be controlled and in a way that they are able to transform from alternating currents to direct currents. The influence of the tube later established the way for the future of transistors. It also made it possible for computers to perform heavy computing problems and used towards other technological inventions.

The tube is made up of two components called a cathode and anode and a key characteristic of having each tube free of any gas removed before it becomes a final product. There are also different versions of the tube. The main purpose of a vacuum tube is to gather electrons, to be sent off to a charged sheet of metal where it becomes positively charged by the electrons. From, this there are different types of tubes like diode, triodes, tetrodes and pentodes. With the main purpose of converting alternating currents to direct currents. An alternating current is electricity that can flow in directions while a direct current is electricity flowing in one direction only. The first sight of vacuum tubes on a computer were seen on the ENIAC computer with hundreds of tubes to produce electric current to the room filled computer.

Well how might this impacted the world of laptop computing? The vacuum tube has influenced greater and compacted inventions that would be later used in laptops to support electronic circuits. Innovation inspired the drive to create something better to have the same if not greater power than the original tube. Which lead to the evolution of transistors to semiconductors and eventually integrated circuits.

So, instead of having thousands of vacuum tubes now we have chips of circuits that are small in size and much more powerful. These chips enable your computer to function properly and help run tasks even calculations.
