Hardware refers to all of the physical (playable) components of the computer: disks, disk drives, monitor, keyboard, mouse, printer, motherboards, chips, and other peripherals.
Instead, software is intangible, it exists as ideas, concepts, symbols, but it has no substance. A good metaphor would be a book: the pages and ink are the hardware, while the words, sentences, paragraphs, and the meaning of the text are the software. A computer without software would be as useless as a book with blank pages.
Hardware types
It is generally classified as basic and complementary, understanding by basic all that device necessary to start the operation of the computer, and the complementary, as its name says, serves to perform specific functions or beyond the basic ones.
Hardware study
The study and design of hardware is a field of study of electronic engineering, the field of electronics encompasses the analysis and design of digital and analog systems. One of the best known digital systems is the microprocessor. Electronics is responsible for the design of these digital systems, so complex, which is where computing is really done.
Electronic engineering encompasses many fields of study such as in the field of electronic control, industrial robotics and micro-botics, home automation, digital signal processing, telecommunications, analysis and design of computer networks, modern control, control theory. , design and implementation of assembly programs with digital electronic devices, the design of computer systems, etc.
In the design of computers, electronics is responsible for the control of peripheral devices, the design of the assembly program for microprocessors, since this science is really what creates the assembly programs that reside in the CPU in the form of instructions, and not it could carry out many important functions that computers have. In the programming of hardware devices, electronics have a widely accepted field in computer design and through which the logic of information movement is carried out.
