WHAT IS FIRMWARE

 What is firmware?


Firmware is a small piece of software that makes hardware work as its manufacturer intended it to.


It consists of programs written by software developers to make hardware devices "tick." Without firmware, most of the electronic devices we use daily wouldn't be able to work. 
They would not do anything.

WHAT IS FIRMWARE


For example, did you know that a simple traffic light has firmware on it? Yes, it does, and the firmware is what tells it to change the lights at regular intervals. 

Without firmware, the traffic light would be just a "stupid" mast, placed on the side of the road, doing nothing except looking bored. What is firmware in the case of less sophisticated hardware devices such as traffic lights, washing machines, card machines, surveillance cameras, and TVs? The firmware is all the software on them, also acting as their operating system and controlling everything about those devices’ functioning. Traffic lights need firmware to run.

We often tend to think about a hardware device as a device that is just hardware. 

And we assume that it just works by itself. However, almost none of the modern hardware devices would work without this particular software written directly onto them.

Earth's shine seems to be fading due to global warming as the oceans heat up

  In recent years, the climate change crisis has escalated to unprecedented levels, resulting in unimaginable and life-changing consequences. An acclaimed new study contends that global warming is dimming our planet, literally! Global warming is causing the Earth's brightness to decrease, according to a new study. Now you're probably wondering, "how do you even measure something like that?" But researchers have their ways. Keeping track of the Earth's shine requires them to calculate the Earth's 'albedo', or reflectance. The albedo is calculated utilizing something called the 'earthshine'. The crescent moon is most noticeable immediately after sunset or before sunrise, when its dazzling crescent gives way to a dark disc with a faint glow. A crescent moon's unlit parts are known as earthshine because they are glowing from the light reflected from the Earth. The study revealed that earthshine data over the last three years indicates that our ...

What is Gun Cotton? How is it different from Black Gun Powder?

  Nitrocellulose (also known as cellulose nitrate, flash paper, flash cotton, guncotton, pyroxylin, and flash string, depending on form) is a highly flammable compound formed by nitrating cellulose through exposure to a mixture of nitric acid and sulfuric acid. One of its first major uses was as guncotton, a replacement for gunpowder as a propellant in firearms. Guncotton was actually developed as a “Smokeless Gun Powder”, Essentially, the main difference between Black Gun Powder and Smokeless Gun Powder is that you need almost zero incombustible components. The key problem with black powder was that it produced a cloud of smoke, not only from Un combusted carbon but also, unavoidably, from ash, the salts formed from whatever anion happened to latch on to the sodium or potassium cations present from the nitrates in black powders. Black powder ash contains a high proportion of potassium or sodium sulfates and carbonates, and because the inorganic saltpeter component was about 2/3 of...
