All computer components are connected to the main board. You can also find more items on the motherboard, such as sound board, operating memory, network board, processor, and modem. These components can be divided into the following groups: input units, output units and processing unit. Inputs and outputs can be attributed to separate groups because the components that these components are part of can receive and distribute information.

A processing unit is a system of components that other components rely on. The computer's processing unit collects all major features on the system, such as processing speed, which limits the number of operations the computer performs in one minute. Operative memory is another important aspect of your computer. The amount of information stored in a computer depends on the amount of memory that is also known as RAM. This information aims to process current data and intermediate information in this memory. This way, the information is available as long as the computer is connected. The operating memory also contains an operating system that cannot be accidentally erased.

You need to get more memory if you want to have a better operating system. That is why you have a ROM memory. Its capacity allows you to hold more amounts of information as long as necessary, without restricting the computer in any way. That way, it doesn't matter if your computer is disconnected because it will still keep the information stored on it. Memory capacity is measured in kilobytes, megabytes, and gigabytes.

Computer software is the logical part, including programs that guarantee good computer performance. The program consists of the operating system and application programs. The main reason for the emergence of the operating system is the need to implement the initial operations of managing computer resources. These operations are low level. It is impossible for a practical user to perform hundreds of initial operations in order to achieve the result they want to achieve. Thus, you can say that the operating system can be associated with an auxiliary translator that translates correspondence between computers and the same user.

An operating system is a set of programs that manages computer resources and ensures their efficiency. This operating system also makes the connection between computer logical components and hardware. These programs lead to full computer activity, they help the user and coordinate programs and applications. These systems are intended for users and administrators, and operating systems used by users with the most security experience. Thus, you have all kinds of Windows versions, but there are also operating systems like Windows NT, Linux, or BSD Free.
