Question
If a function receives an object as an argument and needs to change the objects member data, the object should be:_____________.
A) passed by constant reference
B) passed by reference
C) passed by value
D) none of the above
Answer:
The correct answer is B)
Explanation:
The above question relates to computer programming.
Passing by reference is the same and can be used interchangeably with passing by address.
A special ID used by a computer's procesing unit for recording or tracking data is referred to as a memory address.
When the memory address of a calling function is passed on to the function, the function is said to have been passed by address or reference.
This enables changes to be made to the function or argument directly from the parameter.

Write a function that will sum all of the numbers in a list, ignoring the non-numbers. The function should takes one parameter: a list of values (value_list) of various types. The recommended approach for this:
a. create a variable to hold the current sum and initialize it to zero.
b. use a for loop to process each element of the list.
c. test each element to see if it is an integer or a float, and, if so, add its value to the current sum.
d. return the sum at the end.
In python 3.8:
def func(value_list):
lst = [x for x in value_list if type(x) == int or type(x) == float]
return sum(lst)
print(func(["h", "w", 32, 342.23, 'j']))
This is one solution using list comprehensions. I prefer this route because the code is concise.
def func(value_list):
total = 0
for x in value_list:
if type(x) == int or type(x) == float:
total += x
return total
print(func(["h", "w", 32, 342.23, 'j']))

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%.

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.
What is the advantage of using a translation look-aside buffer (TLB), also called associative memory, in the logical-physical address mapping process? Explain how the logical-physical address mapping logic works using an inverted page table. When does the MMU detect page-fault? Explain four of the main steps for resolving page faults.
Answer:
A) The advantage of using TLB is that it is used for storing the recent transactions of the virtual memory to the physical memory and this is used for the sole purpose of fast retrieval of data
B) When using an inverted table the logical-physical address mapping logic works as a hashing function by connecting pieces of the hardware of logical address and getting them translated to the physical address. this hash function in turn generates the index to the frame table
C) The MMU detect page-fault when there is an exception been raised by the computer when a program is ran to access a memory page and this program is not mapped out by the MMU in the process
The four steps are :
The first step is to check on the memory address requested to make sure of a valid memory request.
The second step is to setup A free frame and a disk operation that is scheduled for getting the necessary page from the disk.
As the the I/O is been completed the processor table is been updated
Finally the Instruction will get restarted from the beginning indicating what might have been caused by a page fault.

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.

wordList is a list of words that currently contains the values ["tree", "rock", "air"]
Which of the following lines will result in the list containing the values ["air", "rock", "air"]
A. wordList[0] = wordList[2]
B. wordList[2] = wordList[O]
C.insertitem(wordList, O, "air")
D. removeltem(wordList,0)
Answer:
A. wordList[0] = wordList[2]
Explanation:
Required
Which line would give ["air", "rock", "air"]
From the question, we have that:
wordList = ["tree", "rock", "air"]
which means that:
wordList[0] = "tree"
wordList[1] = "rock"
wordList[2] = "air"
Analyzing the options.
A. wordList[0] = wordList[2]
This will assign the item in wordList[2] to wordList[0].
and the result would be
So:
wordList[0] = "tree"
would change to
wordList[0] = "air"
The new content of wordList would then be ["air", "rock", "air"]
Option (A) answers the question
The list variable wordList contains three string values, Hence, to obtain the list, ["air", "rock", "air"], the lines wordList[0] = wordList[2] would be used.
List values are indexed from 0 ; hence, tree = index 0 ; rock = index 1 ; air = index 2 To assign the the string "tree" to index 0, then wordList[2] is assigned to wordList[0].wordList[0] is now "air"Hence, the required line of code would be wordList[0] = wordList[2]

d) *(sptr +3) is correct syntax for accessing value in sarray[3] by using pointer
Explain why the expected value of an F ratio is 1.00 when the null hypothesis is true if there is no treatment effect the numerator.
Answer:
The reason is that the f ratio is balanced due to the numerator and denominator having equal sources of variability.
Explanation:
The expected value of an F ratio is 1.00 when the null hypothesis is true because in a scenario where there is no treatment effect, we have both the numerator and the denominator of the F ratio both measuring equal sources of variability.
Whenever this happens then the F ratio will be balanced and also it will have a value that is near 1.00.

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]

List the delay components in the end-to-end delay. Which of these delays are constant and which are variable? Draw a picture to illustrate your network and where each type of delay occurs.
The delay components in the end-to-end delay are processing delay, Transmission delay, Propagation delay, and Queuing delay.
What is an end-to-end Delay?End-to-end delay, also known as one-way delay, is the length of time it takes for a packet to go from its source to its destination across a network. It is a word frequently used in the monitoring of IP networks, and it varies from round-trip time in that only the path from source to destination is measured.
Now according to the question, the propagation, transmission, and processing delays are all constant. The time required to send data bits is the cause.
Variable queuing delays exist.
The waiting time is dependent on packet size, and only one packet can be transferred at a time in the queue process.
