upgradable

Capable of being revised with the expectation that additional features or capabilities will be included. Most software is upgradable. If available, a new version can be successfully installed over an older version, as long as no conflicts with other applications are introduced. Software stored in a flash memory firmware chip may also be upgradable. See firmware.

Desktops Are Upgradable - Laptops Are Limited
USB and eSATA ports enable all computers to be upgraded with external hardware; however, internal devices 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. Storage can be upgraded, but requires some mechanical ability. In addition, unlike a desktop computer, which typically allows a second drive to be added, the laptop's single drive must be replaced entirely, requiring re-installation or copying of the software. See update, USB and eSATA.
