Answer:
B. /etc/fstab file.
Explanation:
The /var/filesystem file is a subdirectory of the root directory of a linux operating system, used to store files during the operation of a computer system.
The /boot/config file is a file directory used to store system configuration parameters which can be accessed by the GPU before the installation of the ARM CPU and linux.
The /etc/mount (or /etc/mtab) and /etc/fstab are used to show the list of mounted volumes. The /etc/mtab gives details of already mounted volumes, but the /etc/fstab shows the list of possible volumes to be mounted upon the boot of the system.
Picking the largest one of input or partitioned data as pivot value
Median of input or partitioned data is expensive to calculate
Data is sorted already and always pick the median as pivot
Choose the incorrect statement:
When the median is always picked as pivot in input/partitioned data, then quicksort achieves the best-case time complexity.
Mergesort has O(N(log(N)) time complexity for its worst case, average case and best case
Insertionsort reaches its best-case time complexity O(N log(N)) when the input data is pre-sorted
Quicksort is practically fast and frequently used sorting algorithm.
Choose the incorrect statement:
In the lower bound analysis by using decision tree, each branch uses one comparison to narrow down possible cases
In the lower bound analysis by using decision tree, he number of required comparisons can be represented by height of decision tree
A decision tree to sort N elements must have N^2 leaves
O(N log(N)) lower bound means that comparison-based algorithm cannot achieve a time complexity better than O(N log(N))
Choose the incorrect statement regarding time complexity of union-find operation:
Inverse Ackermann function does not depend on N and is a constant factor.
When we use arbitrary union and simple find for union-find operation, the worst-case time complexity is O(MN) for a sequence of M operations and N elements
Union-by-size and Union-by-rank both improve the time complexity to O(M log(N)) for a sequence of M operations and N elements
To finish the entire equivalence class computation algorithm, we need to go over each pair of elements, so if we use union-by-rank with path compression for find operation, then the overall time complexity is O(N^2 log*N), where log*N denotes the inverse Ackermann function.
Choose the incorrect statement regarding Dijstraâs algorithm
Dijstraâs algorithm is a greedy algorithm
Dijstraâs algorithm requires to dynamically update distance/costs/weights of paths.
To begin with, Dijstraâs algorithm initializes all distance as INF
Dijstraâs algorithm can be implemented by heaps, leading to O(|E|+|V| log(|V|)) time complexity, where, particularly, log(|V|) is due to "insert" operation in heaps.
i) Picking the largest one of input or partitioned data as pivot value.
ii) Insertion sort reaches its best-case time complexity O(N log(N)) when the input data is pre-sorted
iii) A decision tree to sort N elements must have N^2 leaves
iv) Inverse Ackermann function does not depend on N and is a constant factor.
v) Dijstraâs algorithm requires to dynamically update distance/costs/weights of paths.

Answer:
Linear search can be suitable for searching over an unsorted array. whereas, Elements in the array need to be in sorted order for binary search. The binary search algorithm uses the divide-and-conquer approach, it does not scan every element in the list. Hence, It is the best search algorithm

DMZ
internal network
external network
Answer: DMZ
Explanation:
DMZ is the demilitarized zone network and it is use in providing he various services to the users or customers by using the public internet. It basically contain organizational services in the logical and physical sub-network and usually works in large network.
The main purpose of DMZ that it is use as web server over the internet for reaching to the users and customers. It also add one additional layer in the organization for security purpose.
Some of the services that DMZ provides as web server, DNS and proxy server.
Answer: Drop out
Explanation: Drop out is the situation that is defined as abandoning a study in between after taking up or participating in it.This is considered as the act of withdrawal which can happen due to personal reason, lost interest in the course/study,etc.
Other options are incorrect because abandonment is leaving something before taking up or during the course, margin of error is used for defining the error that occurs in the sample survey and mortality signifies temporality or death.Thus, the correct option is drop out.
Answer:
B.
Explanation:
In Javascript, the if should have a condition attached to it with parenthesis and curly braces.
Answer: All of the above
Explanation: A group is considered as the collection of two or more constituents/individuals. The characteristics of the a group are interaction , interdependence,interaction etc. There is a sense of responsibility and trust to work to achieve goal by depending on each other is described as the interdependence and for this interaction between group is needed as to maintain good communication and also there is a influence of each other on each group member.
