(abbr. HeatSink and Fan) a device consisting of a fan attached to a heatsink (typ. metal fins) used to cool hot chips in the computer (usually the CPU, graphics card, northbridge chip).
(abbr.) An internal 40-pin connection for hard drives, CD-ROMS, Zip drives. see IDE settings
(abbr.) An obsolete expansion slot inside a computer used for a variety of devices. see Identifying Expansion Slots
prefix, a unit of 1000, in computer terms it refers to 210 or 1024

non-standard, a design that belongs to the company that produced it and probably incompatible with other designs and standards.
(abbrev. Random Access Memory) This is what most people are taking about when they say 'memory'. Some people though are talking about the 'hard drive' when they say 'memory'. This is usually the sticks that are put into the computer and the numbers that scroll by when your computer starts up. It is volatile, in that, when power is turned-off, everything is lost from RAM. Identify RAM.
