If an object is passed as an argument, is passed into the parameter variable is option d. a reference to the object.
When does a provided object seen as an argument?The same way we call a function for other variables, we write the object name as the argument when passing an object as a parameter. Example: In this example, a class with an integer variable named "a" and a function named "add" that accepts an object as an input are both present.
Therefore, in the case above, function can receive values as arguments. A parameter variable is a variable that is specific to the function that the argument is passed to. In other words, the value of the argument is copied into the parameter variable.

a network administrator views the output from the show ip route command. a network that is both advertised by both rip and ospf appears in the routing table flagged as an ospf route. why is the rip route to this network not used in the routing table?
The RIP route is not used because OSPF has a lower administrative distance.
Why is the rip route to this network not used in the routing table?The administrative distance of a routing protocol is a measure of its trustworthiness, where a lower number indicates a more reliable protocol. The administrative distance of OSPF is lower than the administrative distance of RIP, so when a network is advertised by both RIP and OSPF, the OSPF route is preferred, and the RIP route is not used in the routing table. This is why the network appears in the routing table flagged as an OSPF route.

the time complexity for inserting an element into a binary search tree is . o(n) o(nlogn) o(n^2) o(logn)
The time complexity for 'inserting' an element into a binary search tree is a: O(n).
A binary search tree (BST) is a special sort of binary tree whereby the left child of a node has a value less than the parent and the right child has a value greater than the parent. A binary search tree helps to maintain quickly a sorted list of numbers. For inserting an element in a binary search tree, it is required to traverse all elements giving the worst-case time complexity of O(n). Thus, the time complexity of inserting an element into a binary search tree is O(n).

suppose the cache access time is 15ns, main memory access time is 220ns, and the cache hit rate is 95%. assuming non-overlapped access, what is the average access time for the processor to access an item?
The average access time for the processor to access an item is 25.25ns.
What do you mean by access time?
Access time is the amount of time that passes between making a request to an electronic system and that request being fulfilled or the required data is provided.
Access time is the amount of time that passes in a computer between the point at which an instruction control unit starts a request for data or a request to store data and the point at which the request is fulfilled or the storage process begins.
Solution Explained:
Given,
hit rate= 0.95
miss rate = 1- hit rate = 1-0.95 = 0.05
cache access time = 15 ns
memory access time = 220 ns
In general average access time is given by:
hit rate * ( cache access time ) + miss rate * ( cache access time + time to hit memory to get data from memory)
We don't need to add cache access time when a miss occurs because parallel access is taking place in this instance.
Consequently, the formula in this instance is:
avg(time) = hit rate * ( cache access time ) + miss rate * ( time to hit memory to get data from memory)
Putting the values in the formula, we have
avg(time) = 0.95 * 15 + 0.05 * 220
= 25.25 ns

Chapter 5 described an atomic attribute as one that cannot be further subdivided. Such an attribute is said to portray atomicity. Outline all the benefits gained from ensuring atomicity in database design. Provide an example of a database design scenario in which atomicity ensures the integrity and flexibility of the database system.
An example of a database design scenario in which atomicity ensures the integrity and flexibility of the database system is transfer of money between two bank accounts.
How is atomicity explained?Atomicity is one of the ACID properties of Transactions that must be enforced by the DBMS's concurrency control and recovery methods. Atomicity requires that we execute a transaction to completion, which means that the transaction is either completely executed or not executed at all.
If the transaction fails to complete for any reason, such as a system crash in the middle of transaction execution, the recovery technique must undo any transaction-related effects on the database. Money transfer between two bank accounts is an example of where atomicity is required. If money is deducted from account A, it must be credited to account B, or the entire transaction must be reversed.

corey flynn (cflynn) currently belongs to several groups. due to some recent restructuring, he no longer needs to be a member of the hr group. to preserve existing group membership, use the usermod -g command listing all groups to which the user must belong. do not include the primary group name in the list of groups. in this lab, your task is to: remove cflynn from the hr group. preserve all other group memberships. view the /etc/group file or use the groups command to verify the changes.
The newgrp command sets up the group membership for a user to log in on Unix-like operating systems. The GNU/Linux version of newgrp is covered on this page.
What Are Groups Used For?A user account is given to every person who has access to a Linux system. A user name and password are just two of the features offered by this user account. Each user is also a part of one or more group accounts.Being a part of a group grants a user special access to system resources, such as files, directories, or running processes (programs). Because many Linux security features use groups to impose security restrictions, this group membership can also be used to prevent access to system resources. Later chapters of this book discuss these security features.To Learn more About Linux version refer To:
