POST

POST￿stands￿for￿power-on￿self-test.￿POST￿is￿a￿test￿performed￿by￿the￿computer￿whenever￿you￿turn￿on￿the￿power.￿POST￿checks￿ system￿integrity.

RAM￿(random￿access￿memory)

The￿computer's￿system￿memory,￿including￿conventional￿and￿ extended￿memory.￿You￿can￿write￿to￿and￿read￿from￿RAM.￿ Information￿stored￿in￿RAM￿is￿temporary,￿and￿is￿erased￿when￿the￿ system￿is￿turned￿off.

Refresh￿rate

The￿refresh￿rate￿is￿the￿rate￿at￿which￿the￿image￿on￿the￿LCD￿screen￿ is￿rewritten￿to￿the￿screen.￿A￿fast￿refresh￿rate￿helps￿keep￿the￿image￿ from￿flickering.

Resolution

The￿resolution￿is￿the￿sharpness￿or￿clarity￿of￿the￿image￿on￿your￿ LCD￿screen.￿Resolution￿is￿measured￿by￿the￿number￿of￿pixels￿the￿ computer’s￿screen￿can￿display.￿For￿example,￿a￿resolution￿of￿ 800x600￿means￿that￿the￿screen￿can￿display￿800￿pixels￿in￿row￿and￿ can￿display￿600￿rows.￿The￿more￿pixels￿displayed,￿the￿higher￿the￿ resolution￿and￿the￿better￿the￿image.￿

ROM￿(read-only￿memory)

Permanent￿computer￿memory￿dedicated￿to￿a￿particular￿function.￿ For￿example,￿the￿instructions￿for￿starting￿the￿computer￿when￿you￿ first￿turn￿on￿power￿are￿contained￿in￿ROM.￿You￿cannot￿write￿to￿ ROM.￿(ROM￿is￿not￿the￿same￿as￿RAM).

Sector

Also￿known￿as￿disk￿sector.￿The￿portion￿of￿a￿track￿that￿is￿numbered￿ and￿can￿hold￿a￿specified￿number￿of￿characters￿(usually￿512￿KB).

Shadow￿RAM

A￿write-protected￿area￿of￿RAM￿that￿contains￿a￿copy￿of￿the￿BIOS.￿As￿the￿computer￿boots,￿the￿BIOS￿is￿copied￿from￿its￿permanent￿ location￿in￿ROM￿to￿RAM.￿The￿BIOS￿can￿be￿executed￿much￿faster￿ in￿RAM￿than￿in￿ROM.￿The￿BIOS￿remains￿in￿shadow￿RAM￿until￿ you￿turn￿off￿the￿computer.
