2: Smartphones

3: Tablets

4: Desktop computers

Answer: 4: Desktop computers

Desktops have been the most effortless devices to upgrade, like adding RAM onto them as the process is fast. Desktop systems are designed expandable so as to have nothing keeping you from inserting components by opening the outer cover and using any available slot for adding or replacing hardware if needed. As opposed to traditional desktop computers that require special tools for maintenance, RAM modules can be easily installed or swapped out by simply opening the case. On the contrary, the laptops, smartphones and tablets are generally limited in their possible upgrades due to their integrated designs and diminished size, thus, at times, it becomes feasible or even impossible to add or replace the components such as RAM except with certain tools or specific knowledge.
