What is the difference between hardware and software on computers
Software and hardware, what difference is there between the two main components of a personal computer?
If you are wondering what the difference is between software and hardware, this article will help you not to get confused. You can thus avoid bad figures and maybe use the information to help you in the study of a fairly complicated and insidious subject such as computer science. First of all, a precise definition of computers must be given. This tool, which has now become fundamental in everyday life, is also called a computer or calculator: it is a programmable machine, within which it is possible to memorize all the instructions needed to perform certain operations and actions.
The two main components of any personal computer are hardware and software. Their activities are the basis for the proper functioning of any device and cooperate so that all operations are successful. Hardware (from English hard, which means hard and ware which means object) is the physical component of the personal computer. It includes all the electronic, electrical, mechanical, magnetic and optical parts, which are part of the set of components, otherwise called tools.
One of the parts that make it up is the processing unit, also called the CPU (Central Processing Unit), or the brain of the computer, that component that executes instructions and processes data. The CPU is in turn formed by the control unit, the arithmetic-logic unit, the registers and the cache memory. The other hardware components are the ROM and RAM storage units, the input devices (mouse, microphone, keyboard etc.) and the output devices (monitor, printer, audio speakers). Instead, the software is the set of programs that are installed on the computer to make it perform certain functions.
The software is divided into system software, the part that manages and supervises the work of the various components of the computer and their interaction, and application software, the part that allows the user to use the computer for certain activities, such as write a text, process an image and so on. In summary, it can be said that the difference between hardware and software consists in the fact that the first is the set of physical components that allow the processing and storage of the data entered, while the second is the set of instructions that make the computer perform certain functions that the user requires.
