Thermal grease
Thermal grease, also called thermal gel or thermal compound, is used to create a heat-inductive layer between a processor and
heat sink. Applying thermal grease between the processor and heat sink increases the heat transfer from the processor to the
heat sink, as the thermal grease has better conductivity than air.
Video card
Video cards process graphics data and send video output to a display device such as a monitor or projector. Video cards can be
of two types:
● Integrated–Often referred to as on-board video card, it is integrated on the system board. In some computers, the video
card is integrated on the processor. Integrated video cards generally share the system memory (RAM) and the may also
utilize the processor to perform video processing.
An Accelerated Processing Unit (APU) is integrated on the same die as the processor and provides higher data transfer rates
while reducing the power consumption.
● Discrete– Discrete video cards are installed separately on the systemboard. Discrete video cards have dedicated memory
on the cardsand generally provide higher performance than integrated videocards. These cards are best suited for graphic
intensive applications,high‑definition video games, and so on.
NOTE:
When a discrete video card is installed on a computer that also has an integrated video card, the integrated
video card is disabled by default. Use the BIOS setup program to select which card to use.
Switchable graphics allow computers equipped with both a low‑power integrated graphics chip, and a high‑power discrete
graphics card to switch between either cards, depending on the load and requirements.
TV tuners
You can use TV tuners to watch television on your computer. TV tuners are available for desktop and laptop computers as
internal or external devices.
NOTE: TV tuners are not supported in all computers.
