Secondary memory (or secondary storage) is the slowest and cheapest form of memory. It cannot be processed directly by the CPU. It must first be copied into primary storage (also known as RAM ).
HDD or Hard Disk Drive
actually HDD or Hard Disk Drive is not memory. It is storage. Memory would consist of RAM ie: DDR, DDR2, DDR3, ETC...
The most simplest is dram(direct random access memory) although this technology isn't used in most modern computers, and because it's so old it is propably the cheapest.
The most expensive memory you can frind per megabyte is 942,518,4562 dollars. it cost this much because you are cheating in your tech class. if you still cant find the answer you must need some extra help.
I'm not sure what you mean by "type" (whether referring to a particular brand or not). Generally, memory that is DDR2 instead of DDR3 will be less expensive. Memory that runs at lower numbers of Mhz, for example 1600Mhz instead of 1866Mhz or 2666Mhz, will also be less expensive and also ram with smaller Gb in their banks will be less expensive. For example: if you had a computer and you were going to put 16Gb of RAM into it, you could achieve that by either putting in 4 banks (4 "sticks") of memory which are 4Gb each or by putting in 2 banks of 8Gb each. A "stick" of memory which is 8Gb is more expensive than a "stick" with 4.

At Home Depot, the least expensive ceramic tile costs $0.78 per square foot. The more expensive tiles are over $3.00 per square foot.

Kruger National Park in South Africa is an expensive place to stay. The least expsive hotel is the Kapama River Lodge, with average prices between $230 and $250 dollars per night.
First eat some kinds of nuts as almond and hazelnut. Then play such games like playing with memory cards. At last but not the least one doing sport is sufficient for example walking at least 20minetse per day.

A type of fuel for RC car, helicopters, and boats. Very expensive, up to £35 per litre
Memory Type: DDR2 PC2-6400, DDR2 PC2-8500, DDR2 (non-ECC)Maximum Memory: 8GBSlots: 4Each memory slot can hold DDR2 PC2-6400, DDR2 PC2-8500 with a maximum of 2GB per slot.
ECC (error correction code) memory can detect 2 bit errors (per 64 bits) but can only correct 1 bit errors (per 64 bits)
