All You Need To Know About Computers

By Steve Hiles


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.

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.

As time went by, and as technology continued to develop, it was discovered that these machines could be made smaller. This consequently would lead to less energy demands. The number of uses would also be immensely increased.

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.

Many embedded gadgets have varying appearances according to the role they are designed to do. A variety of adjustments many be done on a musical device, in order to serve the purposes the user intends it to serve. For example, one may alter the clock or add songs. Although this is possible for some gadgets, for others it is not. This especially happens when these gadgets have been designed to function in a specific way.

The many uses of computers render them very useful to people. Hence they are one of the very important innovations in human history. They enable people to carry out very huge amounts of work in a short duration of time. They can therefore be used to promote accuracy and efficiency at work. Their uses continue to increase with growth in technology.
