What is Computer Hardware and Software?
Computer Hardware and Software: The computer, also commonly known as a computer , is a complex machine that processes and executes orders of various kinds to result in a host of different tasks. Created many decades ago, this device is in constant evolution and is one of the most popular inventions in history , occupying a place in almost every household in the world.
Like the human body, the computer needs a material, tangible and visible part to function , but also of ideas, functions and a “soul” that can not be seen. Both things are called hardware and software .

Parts of a computer
There are three basic elements without which we could not have a computer.
- First, the disk or discs that store the information. The operating system that makes the basics work is saved in the factory , and then the programs can 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 users give , 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 write through a keyboard, or what we print by a printer is what we do all the time , 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.
