Types of Computer Hardware
For the working of the 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 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 fetch process of data is very fast in Ram compare to hard disk. And the DRAM is mostly used in modern computers. 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. 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 rpm. The higher the rpm more is the processing speed of a hard disk.
The high processing speed is used in supercomputers. 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. 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 desktop is connected via a cable and gets fitted in a computer video card which is installed in the motherboard of the computer system. For laptops, tablets the monitor is pre-built in the system and there is no separate hardware installed in these devices.
The CRT was used as an old model of computers. CPU 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. The CPU is made of computer chip which contains billions of small transistors installed on it. All the calculations are performed inside these transistors.
The other hardware components which are monitor, keyboard, mouse, printer, sound system are connected o CPU. It is a hand operator input device that is used to point something on the screen. The mouse can be wired or wireless.
If the mouse is wired it is connected to the CPU directly. The mouse can uses the laser o ball to scroll up or down on the screen. Any movement done from the mouse sends instructions directly to the computer to move the cursor on the screen. The keyboard is another type of computer hardware that is used to give input text, commands to the computer. The keyboard can be wired or wireless. The keyboard contains, alphabets, numbers, special characters and other buttons to give input to the computer.
It is the input device that takes input to the user and processes the commands. The printer is a type of hardware that is used to print something which is seen on the computer and then transfer that displayed information to paper. The printers can be differentiated based on size, processing speed, and other factors.
There are many types of hardware devices present in the market. Choosing the right hardware device with the correct specification gives the best performance result. The hardware devices vary in size, specification and it should be chosen as per the compatibility of the computer system.
Different type of hardware device has a different role. And a complete set of hardware devices makes an effective computer system. This is a guide to Types of Computer Hardware. Here we discuss the basic concept with 7 different types of computer hardware along with respective advantages. You can also go through our other suggested articles to learn more—.
Computer hardware and software
Computer hardware includes the physical parts of a computer , such as the case ,  central processing unit CPU , monitor , mouse , keyboard , computer data storage , graphics card , sound card , speakers and motherboard. By contrast, software is the set of instructions that can be stored and run by hardware. Hardware is so-termed because it is " hard " or rigid with respect to changes, whereas software is "soft" because it is easy to change. Hardware is typically directed by the software to execute any command or instruction. A combination of hardware and software forms a usable computing system, although other systems exist with only hardware. The template for all modern computers is the Von Neumann architecture , detailed in a paper by Hungarian mathematician John von Neumann. This describes a design architecture for an electronic digital computer with subdivisions of a processing unit consisting of an arithmetic logic unit and processor registers , a control unit containing an instruction register and program counter , a memory to store both data and instructions , external mass storage , and input and output mechanisms.
Our projects, designed around the PIC16F84, a powerful 8-bit microcontroller an ideal aid for teaching and learning about computer hardware and software.
2.3. Introduction to Computers
Hardware refers to the physical elements of a computer. This is also sometime called the machinery or the equipment of the computer. Examples of hardware in a computer are the keyboard, the monitor, the mouse and the central processing unit.

Computer Hardware: Hardware refers to the physical components of a computer. Computer Hardware is any part of the computer that we can touch these parts. These are the primary electronic devices used to build up the computer. Computer Software: Software is a collection of instructions, procedures, documentation that performs different tasks on a computer system. The code can be machine-level code or the code written for an operating system.
