Memory
The smallest unit of data a computer can process.
What is a bit?
Interprets, manages and carries out the basic instructions that operate a computer.
What is the CPU?(central processing unit)
The two common types of RAM.
What is DRAM(dynamic random access memory) and SRAM(static random access memory)?
The process of recycling electronic devices.
What is eCycling?
A type of bus which is part of the motherboard and connects the processor to main memory.
What is the system bus or FSB(front side bus)?
Helps speed the processes of the computer by storing frequently used instructions and data.
What is memory cache?
A single chip with two or more separate processor cores.
What is a multi core processor?
This RAM chip must be re energized constantly or all contents in it will be lost.
What is DRAM(dynamic random access memory)?
A technology which uses the constant flow of fluid(s), such as water and glycol, in a process that transfers the hot fluid away from the processor to a radiator-type grill, which cools the liquid and then returns the cooled fluid back to the processor.
What is liquid cooling technology?
This bus connects the processor to cache memory.
What is the backside bus(BSB)?
A circuit board that enhances the functions of a part of a desktop or server system unit or provides connections to peripheral devices.
What is an adapter board or expansion card?
Processors which can execute more than one instruction per clock cycle.
What is superscalar?
A small circuit board where RAM chips reside.
What is memory module?
A small ceramic or metal component with surface fins to absorb and disperse heat produced by electrical components such as the processor.
What is a heat sink?
The number of bits the computer can transmit at one time.
What is bus width?
The two types of memory modules.
What are SIMM(single inline memory module) and DIMM(dual inline memory module).
One billion ticks of the clock system per second.
What is Gigahertz(GHz)?
This DRAM variation is synchronized with the system clock and faster than DRAM itself.
What is SDRAM(synchronous dynamic random access memory)?
A bracelet designed to prevent electronics from electrostatic discharge by preventing the build up of static energy on the user.
What is an anti-static wristband?
The number of bits a processor can interpret and execute at a given time.
What is word size?
The main difference between volatile and non volatile memory.
What is volatile memory loses its content once the computer is turned off however non volatile memory does not lose content even if the computer is powered off.
What are the four basic steps processors perform to execute an instruction?
1.Fetching- Gaining the application instruction or data item from a location in memory
2.Decoding-Translating the instruction into binary
3.Executing-Carrying out the commands
4.Storing-Writing the result to memory
This variation of DRAM transfers data twice instead of once for each clock cycle and is faster than SDRAM.
What is DDR SDRAM(Double data rate synchronous dynamic random access memory)?
Converts wall outlet AC power into DC power.
What is power supply/laptop AC adapter?
This bus is used to transfer actual data and the other is used to transfer information about where the data should be located in memory.
What is the data bus and address bus?
