The importance of computers nowadays for all of us is already well known by the great majority of users. We can use computers at work, at school and at home. We can also have and use computers in our cars and this is also very important because we are all traveling all the time and in this way having a computer which we can take with us on the road is very important. There are many other possible things and activities in which we can use computers as well. In the past, users were no offered as many opportunities as they are being offered nowadays. This is why it is also very important for all of us to be aware of the fact that we need to have the necessary knowledge about our computers so that we might be able to work with them properly and to improve them according to all sorts of changes and improvements being made to computer components which are very important in determining the performance of the computer.

A basic notion about our computers is the fact that they consist of both hardware and software. These two parts are very important and users should be aware of the necessity to always learn something new about them and in this way about their computers. When discussing about computer hardware, a very important aspect which needs to be taken in account by users is the fact that they have to become able to answer the following questions: what are the hardware components of a computer, which are their main functions and how do they actually influence the performance of the computer? All of these three questions have very important answers which can be considered an important key in understanding the way in which a computer functions and the way in which it could be improved when this is required.

The main computer hardware components are considered to be the monitor, the motherboard, the central processing unit, the random access memory, the basic input output system, the hard drive, the CD and DVD drive, the power supply and even others. It can be noticed in this way the fact that almost all computer hardware components are actually considered to be vital in enabling the computer system to operate. They are very important within the computer system and this is why users have to be aware of the necessity to include good computer components within their computers if they want to be able to have a well computer which might enable them to have very good results while working with them.



When discussing about what computer hardware components are within a computer it is also important to be mentioned the fact that they are all tangible components which widely influence the performance of any computer. They are all important in one way or another and many of them actually influence one another so that their importance is even greater.  The computer case is also a hardware component and it is very important because it stores all the other components which enable the computer to function. It protects these components and in this way it enables them to function properly and to determine the computer system to function as it should as well. The central processing unit is considered to be the actual brain of the computer. This is because it deals with all the instructions being operated by the computer system and with the functions of the computer as well. The random access memory is usually attached to the motherboard. Both the motherboard and the random access memory are very important hardware components. The motherboard is very important because on it there are placed many essential hardware components for the computer and others are connected to it.



The random access memory is used to store different types of data but this type of data is only temporarily stored within the computer. Once the computer has been turned off, these types of data will be deleted. The power supply is also very important within the computer. This is because it represents the component which gives power to other hardware components in order to enable all of them to function. Without it other hardware components could not function and in this way the computer could not function either. The hard drive is another storage device included within the computer hardware. It is used to store all sorts of data which remain stored even after the computer has been turned off. It enables users to have access to this data anytime this is required. Nowadays many changed have been made to computer hard drives as well to other hardware components.



These changes are very good to be taken in account by users because they might be enabled to improve their computers by buying some of them. These components are very important to be analyzed in any discussion on computers related to the answer of the following question: what are the hardware components of a computer? Another important component to be considered and analyzed by users is the mouse. It is a very important input device which users appreciate very much as it offers them the possibility to easily choose certain instructions that might be needed to be operated by the computer system. It is also very useful in helping users to select something on their computers screen or on the web pages browsed by them. It enables users to enter in this way certain commands which they need to have operated by the computer in order to receive the necessary results displayed on the computer screen.



When discussing about what hardware components are within a computer it is very important to analyze their importance. In this way, users will understand better what they refer to and how they influence the performance of the computer system. There are five categories of computer hardware components. These five categories are as it follows: the input category, the output one, the storage category, the processing and the category including communication devices. These five categories reveal the main roles of hardware components within a computer. Some are used for data storage and others for processing the necessary data. Some are used to introduce the necessary data to be operated by the computer system and others are used to display the necessary results for users. All of the hardware components are in this way very important and they influence the performance of any computer.
