What is Computer Hardware?
A computer system consists of a central processing unit (CPU) responsible for data processing, one or more input peripherals that allow information input, and one or more output peripherals that enable the output of the processed data.

Hardware Types
Hardware can be divided into two categories:

Essential hardware that covers the indispensable set of components required to give a computer minimal functionality.
Complementary equipment used to perform certain functions that are not absolutely essential for the operation of the computer.
Briefly, a data entry medium, memory, and processing unit and a data output medium constitute the basic hardware.

Strictly necessary data input and output mean application-dependent. From a common user’s perspective, there must be at least one keyboard and monitor for the input and output of information, respectively.

However, it does not mean that the keyboard or monitor cannot be a computer for which it is not required, but you can enter information and extract your processed data through a data acquisition/output card.

Computers are electronic devices that can interpret and implement programmed and stored instructions in their memory; mainly consists of arithmetic-logic and input/output operations.

Data is taken, processed, and stored, and finally, outputs are produced. Therefore, every computer system has components and hardware devices dedicated to them, at least some of the functions:

Processing: Central Processing Unit or CPU
Storage: Memories
Input: Introduction Peripherals
Output: Output Peripherals
Input/Output: Mixed Peripherals
From a basic and general perspective, an input device is a device that provides the tools to allow the entry of information, data, and programs.

An output device provides tools for recording output information and data. Memory gives temporary or permanent storage capacity, and the CPU provides the calculation and processing of the entered information.

A mixed peripheral is a peripheral that can perform both input and output functions, the most typical example is the hard drive.
