Hardware is any component that is physically connected to a PC or a laptop and is used for performing tasks. Computer hardware comprises the major parts of a desktop or laptop computer, including the case, motherboard, processor, hard disk, random-access memory (RAM), video card, hard drive, optical disc, CD-ROM, and battery. Modern PC’s usually has at least one optical disc, one CD-ROM and at least one hard drive. Some additional peripheral devices may also be required for optimum performance.
The components of PC hardware differ according to the type of desktop PC it is used on. The main differences are in the size, speed, type of input and output devices and expansion capabilities. Desktop computers all have different speeds and input and output devices. They can only communicate with one another using a keyboard, mouse or both. Laptops, on the other hand, have more input and output options and are able to communicate with other computers and other mobile devices. Network attached storage (NAS) devices allow local computers to share files.
Desktop PC hardware is divided into analog and digital parts. An analog component is one that produces an electrical signal, while a digital component is one that produces a signal that is interpreted by a computer program. Audio hardware, printers, scanners and televisions are all examples of digital components in desktop computer hardware. The physical components of computer hardware are constantly being replaced, since new technology comes out every few months.
Desktop PC hardware generally comes in three distinct sections: Integrated Circuits (ICs), System Memory (SMs), and Processor Unit (PUs). ICs are the most important part of any PC since they control all the other elements of the machine. System memory is what the CPU uses in order to store applications and data that the computer needs to run. And the last part, the processor, is where all the work is done in order to deliver the output to the computer system.
Much of the old computer hardware that is no longer used can be recycled. In fact, it is becoming quite popular to “recycle” old parts in computers. Some people donate old components to charity, and others even sell them in order to get the money that they need for their own necessities. Recycling programs are widespread and have almost completely eliminated junking. Those who have a bit of computer hardware experience are able to do this recycling themselves.
It is very important to recycle your components in order to make room in the landfill for newer, less harmful materials. If you decide to keep your old hardware, the best thing to do is to donate them. This helps save the environment. Even though laptop computers now have hard drives that can hold billions of pieces of data, that doesn’t mean that you should throw away your old keyboard, mouse or joystick.
