Q:

What is cycle stealing?

Answer

We encounter cycle stealing in the context of Direct Memory Access (DMA). Either the DMA controller can use the data bus when the CPU does not need it, or it may force the CPU to temporarily suspend operation. The latter technique is called cycle stealing. Note that cycle stealing can be done only at specific break points in an instruction cycle.

C) Glorious revolution occured	D) Beginning of the end of cold war

Answer & Explanation Answer: D) Beginning of the end of cold war

Explanation:

The Cold War started with building tensions between the US and the USSR during World War II. As Stalin began to annex more countries and spread communism throughout Eastern Europe, the US began to feel threatened and feared that they would start a war amongst the capitalist nations. The US started an attempt to limit the spread of communism and protect capitalism, which led to a series of passive aggressive and indirectly hostile exchanges between the two nations.

The beginning of the end of the cold war, the Berlin Wall came down. The USSR began to collapse the following year, in 1990.
