upgradable

upgradable

Capable of being revised, almost always with the expectation that additional features or capabilities will be included. All software is upgradable to a certain extent. If available, a new version can be successfully installed over an older version, as long as no conflicts with other applications are introduced. Depending on the intentions of the manufacturer of a machine, software stored in a firmware chip, such as flash memory, may or may not be upgradable.

Desktops Are Upgradable - Laptops Are Limited
A computer may or may not be upgradable. For example, many components in most desktop PCs can be replaced, but there is limited upgradability with laptop computers. In a laptop, memory is typically the only internal component that can be easily changed. The hard disk can be upgraded, but requires more mechanical ability. In addition, unlike a desktop computer, which typically allows a second disk to be added, the laptop's single disk must be replaced entirely, requiring re-installation or copying of the software. USB and FireWire ports enable laptops to be upgraded with external devices, but not internally. See upgrade.
