The Hardware Components of a Computer System are basically the platform for all electronic and informatic functionalities that a computer could have and actually that has and it still takes time to develop and perfect. The history of programming and computational devices pretty much have very close or absolute attachments. While modern computer were invented there were different marcs that are keystone for what we got nowadays, like the first computational device, the first program, the first compiler and others. 

So far, the computers have take solid establishments on most of people’s lives and the capabilities and possibilities have increase, also characteristics such as size and appearance have come to be very convenient and pleasant.

Computers have 5 main parts:

The main part of a computer is defined as the CPU whichs means Central Processing Unit, The CPU is the component of a computer's circuitry that performs data manipulation and executes program instructions. It conducts arithmetic and nonnumeric operations in the arithmetic/logic unit (ALU) and control functions in the control unit (Salem Press Encyclopedia of Science, 2022).

Random-Access Memory (RAM) is the second of the main parts of the computers and it is also called Short Term Memory or Volatile Memory due to its information is lost when the computer shutdowns or restarts.

Storage Devices are a means for computers to retain or keep information even when computers shut down and capacities stores tend to go from megabytes to many gigabytes.

Input Devices: Are usually peripherals that will let you take actions on the interface or programs, such as keyboards, mouses, scanners and cameras. There are other kinds of input devices, such as Audio Devices like Microphones or even gaming controllers.

Output Devices:

Are usually peripherals that would have an external action such as Printers, Monitors, Speakers, and others.

There are other components of computers that are actually very important like the Motherboard, also sound cards, video cards and etcetera.

Computers have an electronic component with integrated circuits, that have microprogramming, and it is essential for the computer to work. Also, the ALU performs the mathematical operations on a programmable device, it adds, multiplies, divides and subtracts. It also carries out binary numbers and then numbers are stored on high-speed storage circuits called registers. After this when computers are functioning and we have screens and images, and there are interfaces, algorithmically based languages and other languages have develop, also it has being possible to draw and modify images or even scan images, which makes a lot possible.

Applications or application software takes a great part of the could do-s of computers, from desktop computers to cellphones, and other devices. Most basically but essentially, able to perform word processing, tables and presentations. Also listen to music, watch movies or make phone calls, but there are many many applications nowadays, with different functionalities.

Thanks to the Computer Hardware we are able to conveniently utilize and do all what we do with computers nowadays. There was an electronic development, but there was a mathematical development also that adhered and had to surge for computers to understand signals and numbers. More in depth there are other ways that computers can perform different operations and tasks, just like with databases. Databases could make different data compilations that can also gets retrieved. Databases have different functions such as storing information or automatically performing calculations. Database management in general requires rigorous teaching or training. Databases is widely used all over the world, for example on stores, libraries, enterprises and on the government.

            The development of computers and computer hardware also have to mention the expansion of common networks and the internet. It is actually very implemented on computers nowadays and that pretty much has also develop a need for protecting data which we could call Network Security. It does take training or a lot of teaching to learn how to Manage Networks in most cases.
