The time complexities of the functions is (a) f1 = f3 < f2
How to compare the time complexities?The time complexities of the functions are dependent on the loops and conditional statements in the function.
From the given code, we have the following highlights:
Function f1: 2 loops and 1 conditional statementFunction f2: 2 loops and 1 conditional statement in the second loopFunction f3: 2 loops and 1 conditional statementConsidering the function f2
The conditional statement in the second loop implies that the conditional statement would be executed several times as long as the loop is valid.
This means that:
f2 > f1 and f2 > f3
Functions f1 and f3 have equal loops and conditional statement.
This means that
f1 = f3
So, we have:
f2 > f1 = f3
Rewrite as:
f1 = f3 < f2
Hence, the time complexities of the functions is (a) f1 = f3 < f2

ii) Explain how space and time overheads arise from use of paging, and how the
Translation Lookaside Buffer (TLB) mitigates the time overheads.
Answers
Answer:
A translation lookaside buffer (TLB) is a memory cache that is used to reduce the time taken to access a user memory location.[1] It is a part of the chip's memory-management unit (MMU). The TLB stores the recent translations of virtual memory to physical memory and can be called an address-translation cache. A TLB may reside between the CPU and the CPU cache, between CPU cache and the main memory or between the different levels of the multi-level cache. The majority of desktop, laptop, and server processors include one or more TLBS in the memory-management hardware, and it is nearly always present in any processor that utilizes paged or segmented virtual memory.
Space and time overheads arise from use of paging, and how the Translation Lookaside Buffer (TLB) mitigates the time overheads contains the most recent jvm to memory address translations.
What is Translation Lookaside Buffer?A computer cache called a translation lookaside buffer (TLB) is employed to speed up the process of accessing memory locations. t is a component of the program memory on the semiconductor. Here between the CPU and also the CPU cache, here between PC and the primary storage, or among several layers of the multi-level cache are possible locations for a TLB.

Given a list of numbers, find the correct function to find the sum of the squares of only the positive elements.
sqsum1
sqsum2
sqsum3
sqsum4
sqsum5
Answers
Answer:
sqsum4
Explanation:
So to raise a number to a power in python, you can use the ** operation, which is usually confused with the ^, which is an operation, but it is not for raising numbers to a power. It is the xor bit operation, which if you don't know at the moment, it's fine, since it's not necessary for this. each of these lists uses a generation comprehension which is generally defined as: (x for x in object if condition) with the if condition being optional, but in this case it's necessary. If it's a bit confusing, you can define a generator using a function so it's a bit more spread out:
def generator(object):
for x in object:
if condition:
yield x
Although in this instance were going to be performing some operation on x, which in this case is squaring it. So let's just look at the two functions that use the **, since they should be the only options that will be correct.
sqsum1(nums):
This function does square x, except it uses incorrect syntax. The condition should come after the for loop. Python likely wont tell you this, because it may think you're trying to do something else. You can do one line if statements like this: a if condition else b, which will return a if the condition is true, and b if it isn't. So it may think that you're trying to do this one line if statement, and say that you're missing an else. The function could even implement in this way: x**2 if x > 0 else 0 for x in nums. This way if the x is negative it counts as 0, or in other words isn't counted towards the sum. But without this fix, the function will raise a syntax error
sqsum4(nums):
This will square each number in x only if the current element "x" is greater than 0, or in other words positive. And then it returns the sum. So this function returns the expected output

D) 1. A transaction has two SQL requests.
2. Both successfully complete.
3. The data is then committed.
Answers
D) Transaction has two SQL requests, both successfully complete, the data is then committed.
Explanation: Atomicity requires that all SQL requests in a transaction should be fully completed and if not, the entire transaction should be aborted. The transaction should be viewed as a single logical unit of work that is indivisible.
A transaction has two SQL requests both successfully completed and then the data is committed. Option (d) is correct.
What do you mean by Transaction?An executed contract between a buyer and a seller to trade goods, services, or financial assets in exchange for money is known as a transaction. The phrase is also frequently used in business accounting.
Atomicity mandates that each SQL request inside a transaction be fully finished; otherwise, the transaction must be canceled. The transaction should be seen as a single, indivisible logical unit of work.
A database's atomicity assures that it adheres to the all or nothing principle. In other words, the database views each transaction as a single, complete entity. As a result, when a database processes a transaction, it either executes it in full or not at all.
Therefore, Option (d) is correct. A transaction has two SQL requests both successfully completed and then the data is committed.
