Types of Hardware Computer
Types of Computer Hardware, it needs both hardware and software components. For every computer system, there can be several hardware components attached to the system as per the requirements. The computer hardware contains mechanical elements and electronic elements of the computer. The hardware of the computer system includes monitor, CPU, keyboard, mouse, printer, sound system, RAM, hard disk and many more. Hardware is used for taking input data from the user, store the data and display the output and execute the commands given by an individual.
RAM: RAM (Random Access Memory) is a type of computer hardware that is used to store the information and then process that information. The processing speed of RAM is much faster than a hard disk but Ram is a volatile device which means when a computer system is shut down all the information stored is wiped out from RAM whereas hard disk is non-volatile which means it stores the data permanently in it. The data can be easily stored in RAM and can be easily fetched from RAM. The fetch process of data is very fast in Ram compare to hard disk. There are two types of RAM SRAM (Static Random Access Memory) and DRAM (Dynamic random access memory). The use of SRAM is in a cache memory of the hard disk is another type of computer hardware that is used to store the data in it. The hard disk can be preinstalled in CPU or can be used as an external device.
Hard disk: The hard disk is the non-volatile component which means the data is stored permanently in hard disk and it does not wipe out when the system is shut down. The hard disk contains electromagnet surface which is used to store huge chunks of data and can be accessed easily. The hard disk has the capacity to store trillions of bytes of data in its storage. In the internal of hard disk, it has a collection of stacked disks which have electromagnetic surface used to store data in it. Every hard disk has a certain processing speed which varies from 4200-15000 rpm. The higher the rpm more is the processing speed of a hard disk. The high processing speed is used in supercomputers.CPU. And the DRAM is mostly used in modern computers.
Monitor: For the computer hardware, the hardware is another device that is used to display the output, videos and other graphics as it is directly connected to the CPU. The video displayed by the monitor uses the video card.
