Sequential and direct access are two methods to locate data in memory. Discuss why major devices now a days use direct access? How can we convert data that is written on a device that supports only sequential access to a device that only support direct access method?
Answer:
Direct data access reduces the speed of retrieving data from memory or storage. Retrieving data and storing it in a cache memory provides direct access to data in the storage.
Explanation:
Sequential memory access, as the name implies, goes through the memory length location in search of the specified data. Direct memory access, provides a memory location index for direct retrieval of data.
Examples of direct and sequential memory access are RAM and tapes respectively. Data in sequential memory access can be access directly by getting data in advance and storing them in cache memory for direct access by the processor.
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

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.

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.

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.
Answer:
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.

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.
