Final answer:
Tablets are typically not upgradeable, whereas laptops offer options to upgrade components like RAM and hard drives.
Step-by-step explanation:
One of the main hardware differences between a tablet computer and a laptop computer is that tablets are typically not upgradeable. Laptops often offer more flexibility for upgrades, such as the ability to increase RAM or replace the hard drive. On the contrary, tablet computers are usually designed with a fixed configuration, which means that the internal components like the storage, RAM, and battery are not intended to be replaced or upgraded by the user. Moreover, in reference to the given options, laptops do not always include a multitouch touchscreen and they typically utilize x86 or x64 processors (Intel or AMD), whereas tablets often use ARM processors.
