Gadgets that can be used to take in commands and compute them accordingly are called computers. These normally have very many functions which could otherwise be too challenging to perform without them. Almost everyone in the world today knows what exactly these are and what people use them for. Nowadays, people can comfortably use them without much stress. They are of many types but the most common ones are those people purchase for personal use.
One of their most striking features is being able to receive commands and execute them appropriately. This is what makes a difference between them and other gadgets like a calculator, which can only execute timely orders. Some specially made calculators, however, have the ability to carry out certain tasks which are rather difficult to perform.
These devices that are able to process information and do computations come in different sizes. While some may need a very long period of time to do even simple calculations, a number of them have the ability to perform very many calculations within a fraction of a second. However, in theory, they all should be able to carry out the same forms of tasks. This means that what a particular computer can do, the other should be able to do. What is only required is to feed in the correct commands and have enough memory.
Sometimes back, these devices were so big in size and used a lot of energy. They were therefore limited to carry out a small number of tasks. These tasks included computing of trajectories for military use or astronomic application.
With time, due to technological improvement, they were greatly reduced in size and power requirement cut down. This enabled them to be used for a wider variety of tasks. This is because power was now being used more economically.
Despite the fact that PCs are very commonly utilized, they were discovered long after many others. Some devices like cell phones, ATM machines, portable organizers, and a large variety of other gadgets devised to help in the flow of information, also have the ability to receive and execute some commands. They are thus known to be embedded nature. They may be differentiated from other forms as they are stagnant in their function.
Different embedded systems vary in both size and shape depending on what function they have been made perform. For instance, a number of changes can be done to an MP3 player device so that one can be able to adjust the time on the clock, and also replace the songs within its memory. However some devices are quite fixed and one cannot be able to change settings that were installed in them during their production. An example is the traffic light device.
It is very clear that computers are one of the most vital inventions in the life of humankind. They help people to accomplish very many tasks which are timely and challenging, within a limited span of time. They can be used to take in information, organize it and keep it. Their use continues to grow with continued technological growth.
