Operating Systems第 25 / 100 题
A user reports that Windows shows only 3.5 GB of usable RAM even though 8 GB is installed. Which is the most likely cause?
a.A 32-bit version of Windows is installed
b.The RAM is faulty
c.The pagefile is disabled
d.The GPU is integrated
解析
A 32-bit Windows install can address only about 4 GB total, so much of 8 GB appears unusable. Upgrading to 64-bit Windows resolves it. Faulty RAM usually causes crashes rather than a clean address-space limit.
