Which of the following amounts of memory BEST represents the upper limit of RAM when using a 32-bit architecture?
A. 2 GB
B. 4 GB
C. 6 GB
D. 16 GB
B. 4 GB
So, the number of bytes it can address is 2^32 bytes, or 4GB. So it makes sense to me that most 32 bit machines limit the amount of ram to 4gb (ignoring PAE).
Theoretically, there is no limit. Even 32-bit CPUs can have an address space above 4 GB. It depends on how the memory management system is implemented in hardware, which is usually independent of the CPU’s word length. Pointers in programs are always word-length, but these are virtual addresses anyways (and not physical), so they are further mapped into a different address space. – Breakthrough

Which of the following printer processes would be LEAST suitable for creating archival documents?
A. Thermal
B. Inkjet
C. Laser
D. Impact
A. Thermal
Explanation:
The printed area from a Direct Thermal printer can potentially fade over time. If the label is exposed to excessive light or heat the material will darken to the point that text may become unreadable and barcodes may lose their ability to be scanned. For this reason, Direct Thermal printing cannot be recommended for “lifetime” applications. While the readability of labels printed with Direct Thermal printing can vary greatly depending upon the environment that the labels are used in, the printing technology still provides enough of a lifespan for common bar code applications such as shipping labels, receipt labels, and nametag labels.
