b. have a least one chip installed
c. use bank compatible chips
d. all of the above
7. When you push down on the RAM chips, be sure:
a. the computer is turned on.
b. the end clips snap into place to hold the RAM securely.
c. you leave an empty slot between chips.
d. the small plastic clips on the side remain in the open position.
8. What prevents you from installing a RAM chip in the wrong direction?
a. notches in the chip
b. the end clips
c. a red light LED indicator
9. To test the RAM chip after installation is complete, you should:

More about RAM
Task: Use an online learning resource to discover more about RAM and how it works.
Assignment: Visit http://computer.howstuffworks.com/ram.htm to learn more about RAM.
Answer the following questions that have been taken from the unit on How RAM Works.
RAM stands for:
Which is true?
o Both RAM and SAM are used in computer systems
o Only RAM is used in computer systems
o Only SAM is used in computer systems
A memory chip is a(n) ___________________ made of millions of transistors
For dynamic memory to work, either the CPU or the memory controller has to
come along and ____________________ all of the capacitors holding a 1 before
Because it has more parts, a ______________________ takes up a lot more
space on a chip than a dynamic memory cell. Therefore, you get less memory
per chip, making it a lot more expensive
The type of board and connector used for RAM in desktop computers has
evolved over the past few years. The first types were proprietary, meaning that
different computer manufacturers developed memory boards that would only
work with their specific systems. Then came ________________, which stands
As processors grew in speed and bandwidth capability, the industry adopted a
new standard in ________________________. With a whopping 168-pin
connector and a size of 5.4 x 1 inch, they range in capacity from 8 MB to 128 MB
per module and can be installed singly instead of in pairs.
Memory chips with built-in error-checking typically use a method known as
_________________to check for errors. Do most modern memory chips use this
type of error checking? _________________________
