Answer:
Explanation:
If the HDD is spinning, this means that the power cable is correctly connected and that the drive is receiving power and powering on. However, this does not mean that the HDD is functioning correctly and reading the information. Therefore, the next logical step would be to check the SATA cable that connects the drive to the motherboard. The cable may be broken or maybe the SATA slot on the motherboard. Switch out the cables and plug it into another slot. If this does not work, then it may be that the HDD is broken. Multiple Beeps can also mean that the RAM or CPU is not plugged in correctly or broken.
Answer:
The target computer's operating system and gain unauthorized access to the hardware, hook into the keyboard with functions provided by the OS, or use remote access software to transmit recorded data out of the target computer to a remote location.
No physical sensation of pressing a button results in misfires. Lack of physical divisions between keys makes touch typing impossible. Smaller key spacing results in typos.
Answer:
tech A only
Explanation:
Technician A is right because a cracked exhaust manifold allows more oxygen into the exhaust stream, which affects oxygen sensor voltage. Technician B is wrong because a clogged air filter raises Hydrocarbons (HC) and also affects O2 (Oxygen) and CO (Carbon Monoxide) levels.
Answer:
11 cycles.
Explanation:
One interesting thing to observe in this is that, there is no data hazard because here in any of the two consecutive instruction, they do not share any common register and hence no collision.
Also assuming each this program starts with address 0, so that condition checking at the end which is "bne $7, $4, 0x040" will not lead to branching which repeats the loop. Which means this sequence of 7 instructions run only once.
Now if there is no pipeline hazard (which is the case here) and there are n instruction with s stages in pipeline with each stage take 1 cycle, then total cycle required to finish the program will be n+(s-1)=n+s-1
Here number of instruction n=7 and in multicycle datapath usually pipeline stages s=5.
Then number of cycles needed to execute this sequence will be = 7 +5 -1 = 11 cycles
