What Is Computer Hardware?

Hardware refers to the physical devices and equipment that comprise a computer system. It is contrasted with software, which is the set of instructions that govern how the hardware functions. Most people associate hardware with the guts of a desktop or laptop computer, but the term actually covers a much broader spectrum of technologies. For example, microprocessors, which are the brains of most computers, are also found in embedded systems that control automobile engines, microwave ovens, and CD players.

When selecting computer hardware for your business, it's important to consider all of the specific needs of your organization. For example, an employee who spends a lot of time on the road for business might benefit from a mobile device with a longer battery life than a desktop PC. In addition, the type of computer hardware selected will have a big impact on your ability to store data and access it from different locations.

There are many different types of computer hardware available, which can make the process of determining which products to purchase overwhelming. However, a comprehensive market research effort is key to making a wise technology investment for your company. In addition, the right IT service provider can help you to navigate this often complex landscape and establish strong partnerships with technology vendors to provide the best solution for your needs.

Computer Hardware Classification

There is a wide variety of computer hardware components that can be grouped into two distinct categories: internal and external. The distinction is based on whether the hardware is housed inside or outside of the case, although there are some exceptions to this rule.

In general, internal hardware components are responsible for processing information created by the software and presenting it to users in real time. This can include things like the monitor, keyboard, mouse, and speakers. In addition, internal hardware can also include a webcam or microphone that is used for communication purposes.

One of the most essential internal computer hardware components is the motherboard, which provides a central hub for all other hardware. The motherboard is essentially a printed circuit board that allows the various hardware components to communicate with one another. Without a functioning motherboard, the computer would not be able to operate properly.

When it comes to external hardware, there are a few broad categories that can be identified. Most common are input and output devices. Input devices are used to issue user commands into the internal processor, and they can include things like keyboards, mice, trackpads (or touchpads), light pens, and joysticks.

Output devices are used to display the results of the CPU's work, and they can be in the form of a monitor, speaker, printer, or projector. A few other types of external hardware include scanners, hard disk drives, and flash drives. Hard disk drives use spinning metal platters with magnetic arms to read and write data, while flash drives employ a similar technology to store bytes on silicon chips.
