What is a computer?
We are all familiar with what the computer is in a specific, current sense. Personal computers (PCs) are found in most aspects of everyday life and for some it is difficult to even imagine the world without them. However, this term means more than simply the Mac and PC we know. The computer is in its most basic machine that can receive instructions and to calculate on the basis of these instructions.
It is the ability to accept instructions - often known as programs - and perform them that distinguishes a computer from a mechanical calculator. While both are able to make calculations, the calculator simply responds to immediate entry. In fact, most modern calculators are actually a computer with a number of pre -installed programs that help with complex tasks.
Computers range from very small to very large. Some are able to make millions of calculations in one second, while others can take a long time to make even the simplest Calculations. But theoretically, anything thatOne computer is able to do, it will also be able. Due to the right instructions and sufficient memory, a computer found in the wrist lessons should be able to achieve everything that a supercomputer can - although it can take thousands of years to complete the operation.
suddenly computers were extremely large and required a huge amount of energy. As a result, they were only useful for a small number of tasks - for example, computing trajectories for astronomical or military applications or breaking code. Over time, they have been reduced with technological progress and their energy requirements have been extremely reduced. This allowed the use of force for stunning series of use.
As computers prevail, they almost do not start scratching the surface of the use of a computer in our world. Interactive devices types contain their own computers. Cell phones, GPS units, portable organizers, ATMs, gas pumps and millions moreH The devices use them to streamline their operations and to offer functions that would not be impossible without one.
Computer, like this, is often referred to as an embedded computer. The inserted type is distinguished from the PC because it is basically static in its function. While PC, some cell phones and some personal organizers may have new software installed and use a wide range of features, the inserted computer usually has only a few purposes that are relatively repaired after the device production.
built -in systems differ in the amount of change to which they can happen after production. For example, the MP3 player is a built -in computer, but it can have quite a bit of interaction and changes to it. This can allow the user to change the colors used, change the clock, update firmware and change songs or lists of songs in memory. One at the traffic light to take another example is probably quite solid. Is set to respond to several certain programs - the time of the day, the trigger when the car PIt will melt, and possibly input from the central database in the case of more advanced systems. These programs are not created for interactivity and will probably never change throughout the life of the system.
The computer is one of the most powerful innovations in human history. With their use, people are suddenly able to perform a stunning amount of calculations at dazzling speeds. Information can be crushed, organized and displayed in the blink of an eye. As the technology continues in the procedure, the computer will undoubtedly become even more ubiquitous - and in many cases it will probably be even less recognizable.
