apply the (1) fifo, (2) lru, and (3) optimal (opt) replacement algorithms for the following page-reference strings:
Answers
This is the page reference strings and the corresponding page replacement algorithms. Page-reference string: 4, 3, 2, 1, 4, 3, 5, 4, 3, 2, 1, 5. FIFO, 4 - - - |4 - - - |4 - - - |4 - - - |1 - - - |1 5 - - |1 5 3 - |1 5 3 2 |1 4 3 2 |5 4 3 2 |1 4 3 2 |5 4 3 2.
For the first four page references, the FIFO algorithm simply puts each page in the next available frame. When page 1 arrives, it replaces page 4 because that is the oldest page. The same thing happens for page 5. Then, when page 2 arrives, it replaces page 1 because that is the oldest page. Finally, when page 5 arrives again, it replaces page 3 because that is the oldest page. LRU, 4 - - - |4 3 - - |4 3 2 - |1 3 2 - |1 4 2 - |4 5 2 - |4 5 3 - |1 5 3 2 |1 4 3 2 |1 4 5 2 |1 5 4 2 |1 5 4 3. For the first four page references, the LRU algorithm simply puts each page in the next available frame. When page 1 arrives, it replaces page 4 because that is the least recently used page.
The same thing happens for page 5. Then, when page 2 arrives, it replaces page 3 because that is the least recently used page. Finally, when page 5 arrives again, it replaces page 4 because that is the least recently used page. OPT, 4 - - - |4 3 - - |4 3 2 - |1 3 2 - |1 4 2 - |4 5 2 - |4 5 3 - |1 5 3 2 |1 4 3 2 |5 4 3 2 |1 5 3 2 |1 5 4 3. The OPT algorithm looks ahead to see which page will be used farthest into the future and chooses the page that won't be used for the longest time. For the first four page references, the OPT algorithm simply puts each page in the next available frame. When page 1 arrives, it looks ahead and sees that page 4 will be used next, so it replaces page 4. The same thing happens for page 5. Then, when page 2 arrives, it looks ahead and sees that pages 3 and 4 will be used next, so it replaces page 3. Finally, when page 5 arrives again, it looks ahead and sees that pages 4 and 2 will be used next, so it replaces page 4.

Write pseudocode for one or more selection statements to decide whether a year is a Leap year. The rules are:
A year is generally a Leap Year if it is divisible by 4, except that if the year is divisible by 100, it is not a Leap year, unless it is also divisible by 400. Thus 1900 was not a Leap Year, but 2000 was a Leap year.
Answers
isLeapYear= false
if Year%4 = 0
if Year%100 != 0 or Year%400 == 0
isLeapYear = true

in a fee simple absolute, the owner has the greatest aggregation of rights, privileges, and power possible. true false
Answers
In a fee simple absolute, the owner has the greatest aggregation of rights, privileges, and power possible is a true statement.
What is a real estate fee simple interest?The word "fee simple" is used to refer to the largest permissible ownership interest in real estate. It is also known as "full ownership." A buyer of real estate (land) typically considers themselves to be the sole owners of the property. In other words, they believe they own the land outright. Therefore, fee simple refers to a sort of ownership or level of rights that an owner has over real estate.
Note: Comparing fee simple ownership to a life estate or an easement covering the real property may help in comprehending it.
Complete legal rights are accorded to the fee simple owner, and these rights are unaffected by time (i.e., they never expire). A fee simple owner, more specifically, is fully authorized by law to possess, use, and transfer the land to others. Anyone else who asserts a right to the real estate has a smaller claim than the fee simple owner, such as a lienholder or the holder of an easement.

Authentication is concerned with determining _______.

There are three basic kind of authentication. The first is knowledge-based — something like a password or PIN code that only the identified user would know.

Answers
The correct way to declare a pointer is int* ptr; Therefore none of the options are correct. So the correct option is option d.
In C++, a pointer is a variable that holds the memory address of another variable. Pointers provide a way to directly manipulate memory and access data indirectly.
The correct way to declare a pointer in C++ is by including the data type followed by an asterisk (*) before the variable name. Therefore, the correct way to declare a pointer is as follows:
int* ptr;
This syntax indicates that the variable "ptr" is a pointer to an integer. The asterisk (*) is an integral part of declaring a pointer variable in C++. Therefore the correct answer is option d. none of the above is correct.
