![]() ![]() The CPU is made of computer chip which contains billions of small transistors installed on it. The CPU is also called the brain of the computer as every operation is executed in the CPU only. The CPU is a core part of any PC, laptops, tablets, and notebooks. ![]() CPUĬPU (Central processing unit) is the core hardware part of the computer system which is used to interpret and execute most of the commands using other computer parts i.e. The LCD is used in a modern computer as they are thinner and lighter and easy to use compared to CRT monitors. The CRT was used as an old model of computers. ![]() There are two types of computer monitors which are CRT and LCD. For laptops, tablets the monitor is pre-built in the system and there is no separate hardware installed in these devices. The desktop is connected via a cable and gets fitted in a computer video card which is installed in the motherboard of the computer system. The monitor can be compared to the television set but the difference is the resolution and graphics displayed by the monitor are of much high quality compare to the television set. The video displayed by the monitor uses the video card. Monitorįor 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 high processing speed is used in supercomputers. The higher the rpm more is the processing speed of a hard disk. Every hard disk has a certain processing speed which varies from 4200-15000 rpm. In the internal of hard disk, it has a collection of stacked disks which have electromagnetic surface used to store data in it. The hard disk has the capacity to store trillions of bytes of data in its storage. The hard disk contains electromagnet surface which is used to store huge chunks of data and can be accessed easily. 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 can be preinstalled in CPU or can be used as an external device. The hard disk is another type of computer hardware that is used to store the data in it. ![]()
