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.

A function is a block of orgaof code that is used to perform a single, related action. Functions provide better modularity for your application and a high degree ofAdvertisement
As you already know, Python gives you many built-in functions like print(), etc. but you can also create your own functions. These functions are called user-defined functions.
Defining a Function
You can define functions to provide the required functionality. Here are simple rules to define a function in Python.
Function blocks begin with the keyword def followed by the function name and parentheses ( ( ) ).
Any input parameters or arguments should be placed within these parentheses. You can also define parameters inside these parentheses.
The first statement of a function can be an optional statement - the documentation string of the function or docstring.
The code block within every function starts with a colon (:) and is indented.
The statement return [expression] exits a function, optionally passing back an expression to the caller. A return statement with no arguments is the same as return None.
Answer:
def functionName( arguments ):
statement1
statement2

Sptr is a pointer pointing to the beginning of an array called sarray. To access the value in sarray[3] by using the pointer, you would use:a) *sptr[*3] b) *sptr+3 c) sptr +3 d) *(sptr + 3)
Answer:
The correct option for accessing the value in sarray[3] is : d) *(sptr+3)
Explanation:
a) *sptr[*3] is wrong option because its syntax is not right it will give errors.
b) *sptr+3 is also wrong option because it will add 3 to the value of sarray[0].
c) sptr+3 is wrong option because it will only access the address of sarray[3] not the value it contains.
d) *(sptr +3) is correct syntax for accessing value in sarray[3] by using pointer

def square(numA, numB):
return numA ** numB
base = 5
power = 2
answer = square (base,power)
print(answer)
numA and power
power and base
numB and power
base and numA
Answer:
numB and power
Explanation:
Correct answer edge 2020
The variables have the same scope for the given function is power and base. The correct option is B.
What are variables?A variable in mathematics is a symbol and placeholder for any mathematical object. A variable can specifically represent a number, a vector, a matrix, a function, a function's argument, a set, or an element of a set.
A variable in computer programming is an abstract storage location with an associated symbolic name that contains some known or unknown quantity of information referred to as a value; or, to put it another way, a variable is a named container for a specific set of bits or type of data.
Because power and base are declared in the same container, they have the same scope. Because they are not present in a function, their scope is said to be global.
Thus, the correct option is B.

Write a program that computes the minimum, maximum, average, median and standard deviation of the population over time for a borough (entered by the user). Your program should assume that the NYC historical population data file, nycHistPop.csv is in the same directory.
Answer:
import pandas as pd
df = pd.read_csv('nycHistPop_csv', skiprows=5)
NY_region = list(df.columns[1: -1])
select_region = input("Enter region: ")_capitalize()
if select_region in NY_region:
pass
else:
raise("Region must be in New york")
def pop(location):
# or used describe() to replace all like: print(df[location]_describe())
print(df[location]_min())
print(df[location]_max())
print(df[location]_mean())
print(df[location]_median())
print(df[location]_td())
pop(select_region)
Explanation:
Pandas is a python packet that combines the power of numpy and matplotlib used for data manipulation. It is good for working with tables that are converted to dataframes.
The nycHistPop_csv file is read to the code to a dataframe called "df", then the user input and the function "pop" is used to automatically generate the statistics of a given region.

What is the minimum size of a data type, in bytes, to be impacted by system endianness. (Whole numbers only)?
Answer:
30
Explanation:
A data type must be at least 2 bytes in size to be affected by the endianness system.
What is endianness system?Endianness in computing refers to the arrangement of bytes inside a word of digital data stored in a computer's memory.
Big-endian or little-endian are the two main ways that endianness is stated.
The least significant byte in a word is kept at the largest memory location and the most significant byte is kept at the smallest address in a big-endian system.
The term "endianness" refers to the arrangement of bytes as they are stored in computer memory. Endianness is classified as big or little depending on which value is stored first.
Thus, for the endianness system to apply, a data type must be at least 2 bytes in size.

Return-from-trap instruction returns into the calling user program while simultaneously reducing the privilege level back to ________ Select one: a. User mode b. Kernel mode c. OS mode d. CPU mode
Answer:
A. user mode
Explanation:
A computer system is a machine that is run by a series of programs that connect the virtual parts (software) to the hardware or electronic parts. The kernel is a computer program that connects the software and hardware of a computer system.
The kernel-mode has several privileges like I/O, interrupts and traps, etc. This mode is tapped by root or administrators to utilize these privileges. Unlike the kernel mode, the user-mode does not have these functions, so a return from the trap instruction (kernel) reduces the privileges back to the user mode.

The comments are adequate to describe the function. B. The lines need to end with semicolons like other C++ statements. C. The parameters should be described more completely. D. The eparaml, eparam2, eparam3 should be just eparam.

A. The comments are adequate to describe the function.
Explanation:
C++ programming language comments starts with two forward-slash ("//") and can be written above a code statement or at the right-hand side of the code statements
The comments of the area() function with three parameters width, height, and length are adequate to describe the function as it does not need to end with a semi-colon.
The task of handling how active processes are making efficient use of the CPU processing cycles is called_______?
Answer:
Scheduling.
Explanation:
A scheduling computer system refers to an ability of the computer that typically allows one process to use the central processing unit (CPU) while another process is waiting for input-output (I/O), thus making a complete usage of any lost central processing unit (CPU) cycles in order to prevent redundancy.
Hence, the task of handling how active processes are making efficient use of the central processing unit (CPU) processing cycles is called scheduling.
In terms of the scheduling metrics of a central processing unit (CPU), the time at which a job completes or is executed minus the time at which the job arrived in the system is known as turnaround time.
Generally, it is one of the scheduling metrics to select for optimum performance of the central processing unit (CPU).
