We explain what a computer is, what is hardware and what is software. In addition, the three basic elements of a computer.
What is a computer?
The computer, also generally known as a computer or computer , is a complex machine that processes and executes orders of various kinds to result in endless different tasks. Created many decades ago, this device is constantly evolving and is one of the most popular inventions in history , occupying a place in almost every home in the world.
Like the human body, the computer needs a material, tangible and visible part to function , but also ideas, functions and a “soul” that cannot be seen. Both things are called hardware and software .
The hardware is the physical elements (peripherals) such as the keyboard, the mouse , the screen or monitor, the cables, platelets and all kinds of elements that form the computer in a solid way. But inside, recorded in memory, we find the software, which are the programs, operating systems and functions installed that give life and coordinate the material to work.
Parts of a computer
There are three basic elements without which we could not have a computer.
- First, the disk (s) that store the information. Here the operating system that makes the basics work will be stored at the factory , and where the programs can then be installed and all the files that are part of our own use of the device can be saved.
- Secondly, there must be units that solve and analyze each of the orders that the users issue , and the ones in charge of this are the processor and the memory. The speed and response of a computer will be provided by these elements, which today can satisfy millions of calculations and executions in a few seconds.
- Finally, it is the peripheral elements that complete the most important functions of a computer. What we see through a screen, what we write using a keyboard, or what we print for a printer is what we definitely do all the time , but that depend on the two groups of things above. Over time we can surely observe the evolution of these devices forever.
