Assume you have a computer that contains 2GB of memory. It contains four memory slots. Each slot can contain 128 MB, 256 MB, 512MB, 1 GB, or 2GB memory modules. Currently, each slot contains a 512MB memory module. What combinations of memory modules will satisfy your memory upgrade to 8GB? Which of these combinations is the least expensive.

Don't switch names.

Provide what YOU THINK about these questions, and a tutor with this expertise might respond.

There are four slots:

* 512MB (1/2GB) +
* 512MB +
* 512MB +
* 512MB = 2048MB = 2GB

To upgrade to 8GB, you might choose to remove the existing chips and replace them, for example with the following configuration,

2GB + 2GB + 2GB + 2GB = 8GB

(2GB x 4)

Can you think of any other ways to do this? For example, if you don't want to buy 4 new chips you could probably reuse 3 of them, buy one new chip and keep one of the old chips as a spare.

Just one possible suggestion.

The suggestion above would not give 8 gig though, unless yu can get a 6.5,

You could keep 2 sticks get a 4g and 3g to make 8.
The cheapest method and using all slots is the one above 2+2+2+2
