| Types of computer hardware:
Ram: RAM (Random Access Memory) is a type of computer hardware used to store information and then process it. The processing speed of RAM is much faster than that of a hard drive, but RAM is a volatile device, which means that when the computer system shuts down, all stored information is erased from RAM while the drive is running. non-volatile hard. , which means it permanently stores data on it. . Data can be easily stored in RAM and can be easily extracted from RAM. Ram data recovery process is very fast compared to hard drive. There are two types of RAM SRAM (Static Random Access Memory) and DRAM (Dynamic Random Access Memory). The use of SRAM is done in the CPU cache. And DRAM is used mainly in modern computers. Hard disk: A hard drive is another type of computer hardware used to store the data it contains. The hard drive can be pre-installed in the processor or can be used as an external device. A hard drive is an immutable component, which means that data is permanently stored on the hard drive and is not erased when the system is turned off. Hard drives contain an electromagnet surface that is used to store large amounts of data and is easily accessible. A hard drive is capable of storing billions of bytes of data in its storage. Inside the hard drive, it contains a set of stacked drives whose electromagnetic surfaces are used to store data. Each hard drive has a certain processing speed that ranges between 420015000 rpm. The higher the number of revolutions per minute, the faster the processing speed of the hard drive. High processing speed is used in supercomputers. Monitor: As for computer hardware, hardware is another device used to display output, video and other graphics as it is directly connected to the processor. The video is displayed by the monitor using the video card. The monitor can be compared with the TV, but the difference is in the resolution and the display graphics of the screen is of very good quality compared to the TV. The desktop computer is connected via a cable and integrated into a computer video card installed in the motherboard of the computer system. For laptops, tablets, monitors are built into the system and no separate hardware is installed on these devices. There are two types of computer monitors, CRT and LCD. CRT was used as an older computer model. LCD monitors are used in modern computers because they are thinner, lighter, and easier to use than CRT monitors. CPU: CPU (central processing unit) is the main hardware of the computer system used to interpret and execute most instructions using other parts of the computer i.e. software and devices. The processor is an essential part of any PC, laptop, tablet, and notebook. The processor is also known as the brain of the computer because each operation is performed only in the microprocessor. The processor is made up of a computer chip that contains billions of tiny transistors installed on it. All calculations are done inside these transistors. Other hardware components such as monitor, keyboard, mouse, printer, audio system are connected to the central processing unit. Mouse: It is a manual input device used to point something on the screen. Mouse can be wired or wireless. If the mouse is wired, it is directly connected to the CPU. The mouse can use the laser ball to scroll up or down on the screen. Any movement made from the mouse sends direct instructions to the computer to move the pointer around the screen. Keyboard: A keyboard is another type of computer hardware used to provide input and commands to the computer. The keyboard can be wired or wireless. The keyboard contains alphabets, numbers, special characters, and other buttons to provide input to the computer. It is an input device that receives input from the user and processes commands. Printer: A printer is a type of hardware used to print something seen on a computer and then transfer the displayed information onto paper. Printers can be differentiated based on size, processing speed and other factors. Reference: https://www.educba.com/types-of-computer-hardware/ Download 123.29 Kb. Share with your friends:
