How memory works
Part 1:
J = 74 = 01001000
a = 97 = 01100001
c= 99
o = 111
b = 98
C = 67

Part 2:
For a hundred dollars at http://www.bestbuy.ca/Search/SearchResults.aspx?query=desktop+memory&lang=en-CA you can find up to 8 GB of RAM or $100. You can get this by getting 4 2GB chips. These chips are sold in pairs with a cost of $41.98 meaning you can buy two pairs with $100.

Part 3:
List six of the ten different types of electronic memory from page 1 of the website. RAM, ROM, cache, flash, BIOS, virtual memory
Check out the Memory Hierarchy Pyramid on the Computer Memory Basics page (page 2) and read the included explanation.. Insert a copy of the picture below and then, in one sentence, explain what it means when Level 2 cache is further up the hierarchy than a USB drive.
It means that the CPU is going to load memory in the level 2 cache faster than from the USB drive
ROM stands for ___read-only memory_____. It is a type of permanent/temporary (highlight one) memory.
BIOS stands for ____basic input/output system_____. It provides basic information for the computer on ____storage devices, boot sequence, security, and plug and play capability__ (4 things are listed on the website)..
RAM stands for ____random access memory___. It is a type of permanent/temporary (highlight one) memory.
Page 2 describes all the things that can be loaded into RAM. List three or four.
-Essential parts of applications -Files open for use in the application
-anything that's open or loaded
What happens to the data stored in RAM when an application is closed?
It is purged(deleted) and sometimes stored in a permanent storage device.
What is the cheapest form of read/write memory available today? Why is it so popular to use large quantities of this kind of storage?
Hard disks, it is popular because people can buy a large amount of memory permanently for a very cheap price.
What does bit-size mean (as in 32-bit or 64-bit computer)?
Bit size refers to how much byte of information the CPU can access from the RAM at once.
The length of the clock cycle is used to determine a CPU’s processing speed. What unit of measurement is used?
gigahertz or megahertz
RAM is not fast enough to keep up with the CPU. Therefore some even higher speed memory is needed. What is this high speed memory called?
cache
Explain registers. Where do they sit on the memory hierarchy pyramid?
The memory cells stored in the CPU that contain vital information for the CPU. They sit at the top of the pyramid.

Part 4:
What are the Memory Address Register and the Memory Data Register? What are they used for?
The Memory Address Register is memory on the CPU that stores information on where to send and fetch data. The Memory Data Register stores data going to a storage unit or data after fetching from the computer storage.
What is virtual memory? How does it relate to the hard drive?
Virtual memory is memory contained in the hard drive there is often large quantities of this memory and it is a slow, but permanent form of memory.
