Computer hardware includes all the internal components of a computer, including the processing unit, main memory, hard disk, processor, video card, motherboard and sound card. The term “hardware” can also be used to refer to the non-software components of a personal computer, which may include printed circuit boards (PCBs), motherboards, input and output devices, cable connections and networking devices. In contrast to software, hardware is less involved and is, therefore, less expensive. Despite the fact that hardware is cheaper, it does not have the same impact on the performance and speed of a computer as software. As a result, some people tend to disregard hardware while ignoring software.
For instance, say you are in the office, and you want to transfer files between your home computer and your work computer without using any software. You simply need an external drive that can transfer the files without any difficulty. With a simple push of the button, the task would be completed. But this scenario is a bit complicated. If you have multiple external hard drives, each with a different configuration, how would you transfer all those files? Without software, your tasks would take place in a completely different manner.
However, if you had software for your external hard disk drives, the new hardware for your CPU would not even enter into the picture. Your software would recognize the disk drives and your CPU would not need any new hardware. Now, if your computer system has two processor cores, each having two logical processors, you would need four physical disks for your two logical processors. This clearly indicates that you have to increase the size of your hard drive if you want to upgrade your computer system.
When it comes to upgrading the RAM of your computer system, you can always go in for faster RAM. However, adding a second hard drive or a sound card may not be possible with the existing RAM. So, what do you do? Well, in such a situation you have to add another physical disk for the additional processing cores. Even though this might be a bit more expensive than the other options, it will ensure that your CPU will be faster.
However, what if you do not have any extra hardware? In such a scenario, you might have to look out for some other way out. If you cannot put in any extra hardware to your computer system, you will have to buy some additional physical elements or you will have to upgrade the RAM and the CPU.
Operating systems and their pre-installed components are another area where people have to make compromises. While Windows operating systems come with a standard set of tools, it becomes imperative to look out for freebies and third-party software packages to customize your system. Some operating systems also come pre-installed with software such as Adobe Acrobat Reader. In such a scenario, you will have to spend a little bit extra money to get these applications installed on your system software.
