Correct Answer: Relationships
Correct Answer: 3
Correct Answer: An attribute that can be broken into components
Correct Answer: Type 1
Correct Answer: All of the above as goals of OLE DB.
Correct Answer: the processing speed depends on DATA BUS WIDTH
Correct Answer: Maximum of 24 logical drives The extended partition can only have 23 logical drives
Correct Answer: There are situations, called hazards, that prevent the next insturction in the instruction stream from executing during its designated clock cycle hazards reduce the performance from the ideal speedup gained by pipelining There are three classes of Hazards: 1 Structural hazards: It arise from resource conficts when the hardware cannot support all possible combinations of instructions simultaniously in overlapped execution 2 Data Hazards: It arise when an instruction depends on the results of previous instruction in a way that is exposed by the overlapping of instructions in the pipeline 3control hazards it arise from the pipelining of branches and other instructions that chage the PC
Correct Answer: The Transmission-Gate's input is connected to the D_LATCH data input (D), the control input to the Transmission-Gate is connected to the D-Latch enable inputs (EN) and the Transmission-Gate outputs is the D_LATCH output(Q)
Correct Answer: Because 8085 processor is 8 bit ALU (arithmetic logic review) Similarly 8086 processor has 16 bit ALU
