What Is It Inside My Computer?

A motherboard is a big circuit board that we use to connect the microelectronics needed for a computer system. Motherboards have connectors which permit main system components like the CPU and RAM to attach to the board. So the CPU, ram and all the other peripherals are using the motherboard in order to communicate and transfer data. We can also attach to the motherboard network, video and sound cards. Nevertheless, several modern motherboards support these features with integrated components. Central Processing Unit (CPU) The Central Processing Unit or CPU is the brain of the computer system. It is the module that processes all of the information within the computer. The kind of processor should be the first decision made when buying or upgrading a personal computer. Very important when selecting a new processor is the CPU's MHz or GHz speed and the bus speed. Higher MHz or GHz means better performance. Hi-tech CPU's need more power and create more heat than other slower models. Therefore, laptop computers, usually use CPU's that are slower and need less power in order to increase the time they can work using batteries. Before buying a new processor, remember that applications continue to evolve. Selecting a CPU of low speed may satisfy today's requirements but upcoming applications will be more complicated and if the processor is not fast enough, the overall user experience will not be acceptable. The processor is placed through a socket on the motherboard and is always the largest module on the motherboard. Random access memory or RAM is a type of data storage. It is used in computers to store programs and information while being processed by the central processor. All computer programs run from random access memory. The amount of RAM is the second most essential factor in computer performance. All the applications require memory to work properly. The more applications that need to run at the same time, the more RAM required. The amount and type of RAM that can be used on a computer system is depended by the motherboard. Controller cards When we close the power any data stored in RAM is lost. Applications and user data must be stored in a medium that will not lose them when the power is removed. Magnetic storage devices, optical storage devices, flash drives and magnetic storage devices preserve data even without any power. Magnetic storage devices are the most common form found in computers. These devices store information in the form of magnetic fields. They include: Hard disk drives, floppy drives and tape drives.
