Disk access is way slower than
memory access. Caching is a technique to improve the disk access time. Block cache is a caching technique which
reduces disk accesses time. Here a
portion of disk is bought to cache for reading and a modified blocks are first
changed in cache but reflected in the disk at one go. On the other hand with write through caching
each modified block is written to cache and at the same time it is written to
the disk. Write- through caching
requires more disk I/O so they can have a negative effect on the performance.
Answer:
def insSort(arr):
ct=0;
for i in range(1, len(arr)):
key = arr[i]
j = i-1
while j >=0 and key < arr[j] :
arr[j+1] = arr[j]
j -= 1
ct=ct+1;
arr[j+1] = key
return arr,ct;
print(insSort([2,1]))

The correct answer is D. Mature Phase
Explanation:
Most products go through four different phases, this includes the emerging phase, the growing phase, the mature phase, and the decline phase. In each of these phases, the product has a different impact on the general market.
In the case of the mature phase, this occurs once the product is established in the market, which means the product is known by many people and is considered as key or necessary. For example, nowadays smartphones are in the mature phase because these are an important part of the market or are key. Moreover, this phase occurs after the product grows in the market, and before it declines. Thus, a product is a key technology during the mature phase.
