Machines which can receive instructions and execute them are referred to as computers. They execute commands according to the information fed into them. These machines are commonly utilized all around the world. Currently a huge number of people find it quite easy to understand what they are and also how to utilize them. There are many different types of these machines, which are distinguished from each other according to their sizes, shapes and efficiency.
Their capability of feeding in instructions and using that information is what makes them special. Other devices like calculators can only yield results to a timely instruction. However, some of the recently designed calculators can do some tasks that are quite challenging.
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.
Traditionally, these gadgets were enormous in size. This necessitated use huge amounts of energy. They could therefore not be used to carry out a wide range of tasks. They only used to perform the very necessary tasks.
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.
Those machines purchased by individuals to carry out their own individual work are the most commonly occurring although they were innovated long after many other types. Some gadgets for example portable organizers, gas pumps, mobile phones and several others that can be used to transfer information, are also capable of taking in information and using it. They are hence known to be embedded. They are however different in that their use is limited.
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.
