What type of device primarily offers modular designs for easy upgrades and repairs?

Desktops are primarily designed with modular components, allowing for easier upgrades and repairs compared to other types of devices. This means that individual parts such as the CPU, RAM, storage drives, and graphics cards can be replaced or upgraded without needing to replace the entire system. This modularity is a key advantage, as it enables users to adapt their systems to new technologies or performance needs over time, significantly extending the lifespan of the device.

In contrast, laptops, tablets, and smartphones generally have more integrated designs to achieve portability and compactness. This can often limit the ability to upgrade or replace parts without specialized knowledge or tools, making desktops the superior choice for those seeking modularity and ease of repairs.
