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 ability to take commands and use them is what makes a difference between them and other electronic devices like the calculators. For instance, a calculator will only give results to an immediate command, which is unlike a computer. Actually, a number of most recent calculators have certain programs that help them to perform tasks that are not so simple.
These gadgets with ability to taking in commands and executing them accordingly have various sizes. Their efficiency also varies in that some will take hours or even days to complete a certain number of tasks while others will need only a few seconds to get the same amount of work done. In actual sense, all these gadgets should be capable of performing all the tasks which any of them can perform. The implication of this is that a particular machine will be capable of doing what any other can do. The only thing that is needed is the appropriate command and memory that is sufficient.
In the past, these machines were constructed in such a way that they were very large in sizes and consumed so much power. Thus, they were only utilized to do limited variety of functions. These functions are those like to compute trajectories used by astronauts or in the military. Therefore, they were not put into their full use.
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.
Various embedded devises come in different sizes and shapes, based on the work they are meant to carry out. For example, many alterations may be carried out on an MP3 gadget in order to for one to be capable of adjusting the clock time and to remove songs in it and put new ones. However, for some gadgets, this is not possible as they contain fixed settings. These settings are originally installed when they are being produced. A good example is the devise used in traffic lighting.
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.
