Cache - is a temporary storage location that enables fast retrieval to allow for fast processing
SRAM - Static Random Access Memory: it is volatile, meaning when power is removed the memory is lost, it is more expensive then DRAM and requires more transistors therefore more area. But it is uses less power because the capacitor does not discharge.
DRAM - Dynamic Random Access Memory: it is non-volatile, meaning when power is removed the memory is conserved, it is less expensive requires less transistors than SRAM but consumes more power because of the leakage from the capacitor and the memory needs to constantly be recharged, hence "Dynamic" the constant raising and lowering of voltage.

LOGIC GATES:
Adders - Full adder with a carry has the following: sum = (A^B)^Cin and Cout = (A*B)+(Cin*(A^B))
Flip-flop - A D-FF will have an input 'D' and a output 'Q' and also a clock and possibly a reset: the input will hold the data until the clock cycle changes whether on the positive edge or negative edge and the output will receive that value and hold it until the next clock cycle. This can be used as a storage (or register) in which you can probe the output and see what the value of 'D' was at the previous clock cycle.

Someone from Intel Corporation gave me information about what to expect in the job interview at Rooftop Slushie.
