A computer with a 240-watt power supply is connected to a 120 V circuit and is left on continuously for one month (31 days). How

much current does it draw? What is the resistance of the computer? How much energy does the computer use if it does not enter a power save mode? If electricity costs $0.11/kW hr, how much does it cost to leave the computer on for a month?

Answer:A load has resistance and this is measured in ohms. Every electrical device or load has resistance. Resistance is like a restriction to the flow of electrons and electricity is dissipated as heat energy in a resistance. For a fixed voltage applied to a load, the higher the resistance, the lower the current. Going back to the water analogy, when you stand on a hose, you increase the resistance and restrict the flow. The only way to restore the flow is by getting the pump to pump harder, and force water through the restriction, i.e. the pump needs to have a higher pressure. Alternatively if you take your foot off the hose, you increase the diameter and lower the resistance and more water can be forced through. In an electrical circuit, if the voltage is increased, more current is forced through the resistance. If the resistance is lowered, more current will flow even if the voltage doesn't change. Even connecting wires in a circuit have resistance, so when high currents need to be carried by a cable, it needs to have a sufficiently large diameter and cross sectional area (CSA) to avoid overheating.

A computer’s memory is composed of 8K words of 32 bits each. How many bits are required for memory addressing if the smallest ad
victus00 [196]

Answer:

The minimum number of bits necessary to address 8K words is 13.

Explanation:

You have the number of words to address that is 8000 words, a word is the smallest addressable memory unit.  

8000 words can be addressed with 2^{n}  units. Now you have to find the value of n that approximates to the number of words.  

2^2=4\\2^4=16\\2^7=128\\2^{10}=1024\\2^{12}=4096\\2^{13}=8192

So you can see that 13 bits are needed to address 8K words.

Describe copyright statute, disclaimers, and filing procedures.
gayaneshka [121]

Answer:(Answers may vary.)

I researched about different concepts regarding statute of limitations, disclaimers, and filing procedures regarding copyright issues.

Statute of limitations

Statute of limitations for copyright falls under two categories. The first is a limitation for ‘Criminal Proceedings’. In this case, the statute stands that the claim (or lawsuit) has to be filed within five years of the cause (act of infringement). The second consideration is in the ‘Civil Action’ case. Here the claim (lawsuit) has to be filed within three years of the cause. Many times the last act of infringement is taken as the date from which these five (or three) years are calculated. There have been cases where the date when the infringement was discovered by the victim, is taken as a starting date.

Disclaimers

A disclaimer is a statement that is intended to pass on some information about the content of the design to the viewer. This disclaimer may be to signify the intent of the designer behind the content. It may also be a suggestion or warning to ensure the viewer uses discretion while viewing the content. A disclaimer is mutual understanding between the designer and viewer. This would protect the designer rights in a situation where the viewer claims damages after the viewer clearly disregarded the disclaimer.

Filing procedures

A claim for copyright has to be filed (ideally) before any infringement occurs, or within three months of the infringement. Timely registration would help the claim for damages. I can file for a copyright online (U.S. Copyright Office). I can also file for a copyright in printed form at the U.S. Copyright Office. I would need two copies of my work at the time of filing. The online facility is charged (fees) lesser than direct submission. I would have to sure which form I fill, as all the forms refer to different types of work.

Explanation: I just did it and it showed me.
