Answer:
1. PCB0
2. PCB1
Explanation:
Given that PCB is often referred to as Process Control Block, is a form of data structure that is applicable and utilized by the computer operating systems to store all the information concerning a process.
This process is carried out in a way that when Process P0 is initialized, the operating system established a related process that takes the computer processing unit from Process P0 and allocates it to Process P1, the Operating System, in turn, will save P0's PCB, and then reload P1's PCB.
Hence, If process P0 is switched to process P1, the state for P0 will be saved into "PCB0" and the state from "PCB1" will be reloaded.
What is the capacity of a disk with two platters, 10,000 cylinders, an average of 400 sectors per track, and 512 bytes per sector?
What is the use of cache memory? Explain the concepts of cache hit and cache miss.
Answer:
The capacity of the disk is "40 GB".
Explanation:
Given value:
[tex]\to \text{cylinder}= 10,000\\\\\to \frac{sector}{track} = 400\\\\\to \frac{bytes}{sector} = 512\\[/tex]
[tex]\text{Calculating the size of track} = \frac{bytes}{sector} \times \frac{sector}{track}[/tex]
[tex]= 512 \times 400 \\\\ = 204,800 \ \ Or \ \ 200 \ K[/tex]
[tex]\text{Calculating the size of surface} = \frac{byte}{track} \times \ cylinder[/tex]
[tex]= 2000 \ K \times 10,000 \\\\ = 20, 000,000 \ K[/tex]
[tex]\text{Calculating the capacity of a disk} = \frac{byte}{surface} \times \frac{surface}{disk}[/tex]
[tex]= 20, 000,000 \ K \times 2 \\\\ = 40, 000,000 \ K \\\\= 40 \ GB[/tex]
Cache memory is often used to speed up the runtime. It will enable us to improve performance unless we can store information, that is retrieved constantly in memory space.
Hit Cache: when the Processor relates to representing database data, Cache Hit results. Miss Cache: when this Processor responds to a non-present cache data, this will trigger its miss of cache.It doesn't have to retrieve the Main Memory through secondary storage.Pleases Help ME An example of a _________________ impact is when a product is back ordered and the business contacts the customer via email to let them know of the new ship date.

jeremy has a handful of resisters and all of them except one have for bands the exception has three why?
Answer:
The 3 band resistor does not specify the tolerance.
Ususally this means the tolerance is 20%, which is not great.
Explanation:
The last band is typically the tolerance band, i.e., the lower the tolerance the more accurate the value as indicated by the other bands. In case of a 3 band code, there is no tolerance specified and you have to assume the default of 20%.

What are some areas in Computer Science that make use of multivariate statistical testing or MCM methods? Explain why they are used.
Explanation:
Computational modeling is one of the areas of Computer Science that uses mathematical systems to perform multivariate statistical tests to solve highly complex problems in multidisciplinary areas, such as medicine, engineering, science, etc.
An example of the use of multivariate statistical tests is social development research in social science, which uses multiple variables to find more hypotheses and greater coverage between variables.
Multivariate statistical tests have the benefit of making research more effective and providing a more systematic and real view of the study.

During periods when the internet is not slowed by congestion, the number of internet searches is probably close to the socially efficient number. how can we tell this this is true?
Answer:
We can this is true because the number of internet searches that are being done at that time is just enough to meet the actual capacity of the internet facility.
Explanation: Socially efficient number is that number that is just enough to meet the actual capacity of a given system such as an internet connectivity or internet facility.
When the number of internet searches are just enough not to cause congestion in the search engines or internet facility,it can be said that the socially efficient number has been achieved.

Suppose that one of the following control signals in the single-cycle MIPS processor has a stuck-at-0 fault, meaning that the signal is always O, regardless of its intended value. What instructions would malfunction? Why? (a) RegWrite (b) ALUOp1 (c) MemWrite Repeat for all three signals (a) to (c) above, assuming that the signal has a stuck-at-1 fault.
Answer:
Explanation:
RegWrite:
• All R-type instructions, lw and addi:
• The result of the operation/load/addition would not be written back to the destination register
• ALUOP
• The following R-type instructions: add, sub, and, or, slt
• With ALUOp stuck at 0, the ALU decoder would interpret all those instructions as either add or subtract operations. The ALUOp gets decoded to add or subtract depending on ALUOp[0].
• MemWrite:
• Only sw is affected.
• The memory write won’t take place.

The function should return a new list giving the average velocity between consecutive time measurements. The new list should have length one less than the original lists.
Below is the function that takes two parallel lists;
List of times in increasing order and that of distance travelled by that point in time.
I put into consideration the instructions given in the question.

you are packing a mobile phone containing a lithium ion battery and you get a prompt on the screen to put a lithium ion label on the box. You have run out of such labels and have only lithium metal labels left. what should you do?
Answer:
Do not use such labels because they may be misleading and are unethical.
Explanation:
Note, there is a big difference in design between the two terms or labels. Lithium metal batteries are non-rechargeable batteries. In other words, they cannot be recharged after they run down. For example, most watches, calculators, or car keys are made of lithium metal batteries.
While Lithium-ion batteries (or Li-ion batteries) are rechargeable batteries , and they are commonly used by mobile phones, laptops, and other gadgets.
Therefore, with such differences in mind, it may be very misleading when someone in possession of the mobile phone sees the lithium metal labels; then thinks the battery is non-rechargeable.
There are different instructions that comes with labeling, lithium metal label is quite different from Lithium-ion labels and as such one cannot use one for the order.
What one should you do is to never use the lithium metal labels in place of Lithium-ion labels. It is better to go and get the required label. If not found, the mobile phone should not be packaged for transport.
One has to comply with the regulations regarding batteries and the packaging of lithium batteries.
Lithium Metal Batteries are known as primary battery. That is, they are non-rechargeable. They are said to have lithium metal or lithium compounds in them.
They have high energy density than other lithium batteries. They can be found in Watches , Calculators etc.
Lithium-ion batteries are known to be secondary battery. That is, they are said to be rechargeable in nature. They can be found in Mobile phones, Laptops etc.
When shipped, any packages that has lithium-ion batteries must be labeled with UN3480 or UN3481.
When shipped, any packages that has lithium metal batteries must be labeled with UN3090 or UN3091.
