We explain what a computer is, what hardware is and what software is. Also, the three basic elements of a computer.
What is computer?
The computer, also generally known as the computer or computer, is a complex machine that processes and executes orders of various kinds to result in a myriad of different tasks. Created many decades ago, this device continues to evolve and is one of the most popular inventions in the world. 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 are called hardware and software.
The hardware is the physical elements (peripherals) such as keyboard, mouse, the screen or monitor, the cables, platelets and all kinds of elements that make up the computer in a solid way. But inside, recorded in memory, we find the software, which are the programs, operating systems and installed functions that give it life and coordinate the material to function.
Parts of a computer
There are three basic elements without which we could not have a computer.
- First of all, the disk (s) that store the information. Here the factory will be saved operating system that makes the basics work, and where you can later install the programs and save all files which are part of our own use of the appliance.
- Second, there must be units that resolve and analyze each of the orders that users impart, and those 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 type using a keyboard, or what we print on a printer is what we ultimately do all the time. weather, but that depend on the two groups of things above. Over time we will surely be able to observe the evolution of these devices forever.
