Internal computer hardware motherboard set up the motherboard in the computer, and it has other names such as: The system board, the main board, and its primary function is to provide a connection between the CPU and RAM, and between other parts of the computer, and the motherboard has several types; each type works with specific types of processors and memory modules.CPU the central processing unit (CPU) crosses the brain of the computer, as the device responsible for the interpretation and implementation of the system of factors issued by the program and the devices connected to the computer, and was introduced in all modern electronic devices, the central processing unit (cpu) two main components, Hamama comes: : (CU); the component responsible for extracting information from memory, translating and executing it. Unit of arithmetic and logic: (ALU); it is the Muslim universe for His Excellency arithmetic and logical operations and solve them correctly. Power supply the power Supply is also called the power supply unit (PSU), and the power supply and its functions, including:provides power to the computer. It pulls the right amount of electric current and converts the current frequency into a constant current. Regulates the electrical voltage to eliminate the resulting mutations of electrical systems. Power supplies are classified based on the number of watts they generate, the more power a computer has, the more watts it provides. HDD terminals are classified as the largest part of the internal parts of a computer, where data, such as: the operating system, most files, and some accounts contain return letters to the drives, such as: (c, D, e) representing the partitions of the drives, and usually your operating system on the primary hard drive. Random Access Memory (Random Access Memory) has a temporary storage unit in the computer, where the information stored in it is provided once the computer is closed, and it is proved that was the last one on the motherboard, and can install a chip and one or more of the chip on the motherboard, and there are two types of random ones, namely: the idea of random dialing DRAM, andPlants its international research station was international (ODD; Plants its upper) technology transfer stuff laser, complete this technique to complete its data from its external, Where is the empowerment process and the data, modify and delete, and it is perfect on Poverty Photo perches pays: (cd, dvd, blu-ray).
