21
Q

Expansion Slot

A

An expansion slot is a hardware interface that enables the communication between your PC and expansion devices such as sound cards, network cards (Wi-Fi, Ethernet, Bluetooth), and other connector cards (USB, FireWire, eSATA).

22
Q

Heat Sink

A

An aluminium or copper cooling device that conducts heat from the processor to the thin metal fins to radiate it into the air.

23
Q

Cooling Fan

A

A form of “Active Cooling” that uses an air cooler to blow air and improve heat dissipation.

24
Q

Heat Pipe

A

A hollow device filled with a special fluid which helps to carry heat away from the processor to the fins.

25
Q

Liquid Cooler

A

A device that uses water or some other fluid pumped through tubes to a heat sink away from the CPU.

26
Q

Thermal Paste

A

A heat conducting pad placed in a thin layer to improve the heat transfer by eliminating air gaps.

27
Q

Name all types of expansion slots and what they are used for?

A

PCIe = used by most new expansion cards
PCI = used by older expansion cards
Mini-PCI and Mini-PCIe = Used primarily for internal expansion of laptops and compact PCs
ExpressCard = used to expand laptop devices via an external slot

39
Q

CPU Characteristics

A
  • Core Count = A core is an independent processor embedded on to CPU. It can process a single instruction stream or thread at a time.
  • Ability to hyperthread = Also known as simultaneous multi-threading (SMT) places additional registers on a physical core, allowing it to behave like 2 logical cores.
  • Cache = The CPU cache is fast memory used to process instructions or data. An instruction cache speeds up executable instruction fetching. A data cache speeds up data fetch and store.
  • 32-bit or 64-bit architecture = The processor’s bit-value tells you how many bits it uses for its memory addresses. 32-bit supports maximum of 4GB of RAM. 64-bit supports anything over 4GB.
  • Integrated GPU = A graphics processing unit on the same chip as central processing unit. This allows for the CPU to directly control displays, provided that
  • Virtualization = allows your computer system to run as a unique computer system with full access to all hardware for individual applications. For example, with virtualization, your computer can run a Linux operating system for one application and a windows operating system for another.
  • No-execute bit (NX Bit) = A security feature that allows the operating system to classify areas of memory as non-executable, preventing the CPU running any code residing there.
  • Clock Speed = every processor has a clock speed that determines how quickly it can process data. Modern CPUs used in PCs and mobile devices range roughly between 1 GHZ and 5 GHz clock speed.
40
Q

CPU Cooling methods
