The functionality of a laptop and desktop is similar; however, the hardware and compatibility of various software are different. A desktop is a graphical user and physical computer unit that operates on a software operating system such as a windows desktop (Bagheri, Severin & Rajan, 2020). On the other hand, a laptop is an all-in-one computer that uses AC or batteries to store data for several hours connected to power directly. The research will compare one Mac and PC based on processor, memory, graphics processor, connectivity, and price. In almost all cases, Macs outperforms PCs in many cases due to hardware optimization, although it has a skimp RAM than the PC. In my case, I will compare the Apple iMac 27-inch (2020) and Dell SPS 8940 (PC).

Literature review

The advancement in technology has increased the manufacturing and the sales of desktops and laptops. Approximately 94% of the entire population uses laptops and desktops to access information from the internet. The use of desktops, laptops, and other internet devices such as smartphones and tablets will continue to grow since people are aggressive and proactive in connecting with others across the globe through the internet. Based on Subramanian & Yung (2017), the manufacturer aims to shift from desktops to All-in-one PC (APC) due to the many advantages of using the PC.

The modern PC ensures that the user can control the internet devices all-in-one PC. The main reasons many people shift from the desktop to the PC are portability. It is easier to maintain a laptop than a desktop since all the hardware is connected together. The use of a PC is also environmentally friendly since it reduces power consumption. The use of a desktop has become an outdated technology because of its complexity in maintenance and portability.


Apple iMac 27-inch (2020)

Apple iMac 27-inch (2020) is one of the perfect examples of all-in-one for all. The PC provides the user with the highest experience in the field of technology since it is packed with powerful tools, incredibly intuitive, and beautifully designed (Onwuchekwa, 2021). The device is a 27-inch model with expanded memory and storage, faster graphics, and a processor. The other main advantage of the device is that it has clear pictures and a large hard disk for video and audio storage, including a stunning Retina 5K display that is faster and better than ever.

Additionally, the Apple iMac 27-inch (2020) accommodates 500 units of brightness and one billion colors that enable a user to experience the graphics and photos leap off the screen. It also contains a non-textured glass option and true tone technology to minimize glare. The Pro Display XDR has played a critical role in reducing the eye challenges associated with workplaces with lightning conditions, direct light, and sunlight. Contrary to the typical matte display coating, the new technology nano-texture in the Apple iMac 27-inch etched into the glass at the reduced nanometer level.

Dell XPS 8940

THE Dell XPS 8940 model was released in 2020 specifically for gaming, a pre-built home. Dell XPS 8940 has 128GB of DIMM DDR4-2666/2933 memory. It accommodates 10th gen Intel Core processor. The motherboard utilizes the H470 chipset. It is developed with a pre-built Display Port output or graphics card with HDMI. The model in this category contains better cooling, multiple drive bays, and 4x PCle slots. Dell XPS is the best option for users looking for a device with little upgradability (Towne, Ory, Smith, Peres, Pickens, Mehta & Benden, 2017). The model contains a dedicated GPU warning. The user will know where there is enough power supply through the application. However, some PSUs lack the dedicated GPU warning, and therefore, the user must purchase an auxiliary PCle power connected to monitor the power supply.
