What are heat sinks? How do they work?
A component designed to lower the temperature of an electronic device by dissipating heat into the surrounding air.
Explain how liquid cooling systems work?
As the liquid passes through the heat sink, heat is transferred from the hot processor to the cooler liquid.How is Thermal compound used?
Thermal grease is primarily used in the electronics and computer industries to assist a heat sink to draw heat away from a semiconductor component such as an integrated circuit or transistor.
Briefly explain the difference between DRAM, SRAM, SDRAM, DDR, DDR2, DDR3, RAMBUS?
Dynamic Random Access Memory
Static Random Access Memory
Synchronous Dynamic Random Access Memory
Double Data Rate
Double Data Rate 2
Double Data Rate 3

What are processor sockets?
Mechanical component that provides mechanical and electrical connections between a device and printed circuitList Bus slots?
ISA, VESA, PCI-X, PCI ExpressWhat is PATA? IDE? EIDE?
Parallel ATA is a hard disk interface also known as IDE. EIDE is an enhanced version of IDEWhat is SATA, eSATA?
Serial Advanced Technology Attachment. eSATA is a special connector for external devicesWhat is BIOS/CMOS?
BIOS is basic input/output system. CMOS is complementary metal-oxide-semiconductor1.3 Classify power supplies types and characteristics
1.4 Explain the purpose and characteristics of CPU's and their features
There are many types of power supply. Most are designed to convert high voltage AC mains electricity to a suitable low voltage supply for electronics circuits and other devices. A power supply can by broken down into a series of blocks, each of which performs a particular function. Identify 2 CPU types?
PC, Mac What is Hyper threading?
is Intel's term for its simultaneous multithreading implementation in itsAtom, Core i3, Core i5, Core i7, Itanium, Pentium 4 and Xeon CPUs. Explain Speed (real vs. acual)?
Real speed is the computer at its maxium potential, which is really is never at, Actual speed is the speed it really goes.
Explain 32 bit vs. 64 bit?
The terms 32-bit and 64-bit refer to the way a computer's processor (also called a CPU), handles information. The 64-bit version can handle large amounts of random access memory (RAM) more effectively than a 32-bit system.
